Introduction

Congratulations on your purchase of the M-Audio ProFire 610 audio interface. ProFire 610 is part of M-Audios award winning series of FireWire1-baseddigital recording systems and features solid hardware design, robust driver technology, and a powerful Control Panel application to help you capture your best performances with the highest possible fidelity. This rugged interface includes many features found on the flagship ProFire 2626 interface including a powerful DSP-based monitor mixer, high quality preamplifiers featuring Octane technology, two discrete headphone outputs, and an assignable Master Volume Control knob to facilitate many 1 A bout 1394 iLink and kinds of recording and mixing. Furthermore, the portable design and bus FireWire: powered operation of ProFire 610 allow you to make professional-grade recordings anywhereat the studio or on the road. Some computer manufacturers Even if youre an experienced digital recording enthusiast, please take a moment to read through this User Guide and familiarize yourself with the features and operation of ProFire 610. You may also want to refer to your audio softwares documentation to better understand how ProFire 610s features are integrated with the program. Your experience and enjoyment of your ProFire 610 will be greatly enhanced by a good working knowledge of your audio software.

Headphone Monitoring

ProFire 610 features two headphone outputs on its front panel. The first headphone jack outputs the same audio signal as rear-panel outputs 1/2 while the second headphone jack outputs the same audio signal as rear-panel outputs 3/4. The first two tabs of the Control Panel (e.g., the Analog Out 1/2 and Analog Out 3/4 tabs) are used to set up mixes for these outputs, respectively. Headphone monitoring and mixing is covered in greater detail in the About Overdub Recording and Monitor Mixing section of this guide. NOTE: f the Master Volume knob 9 is assigned to control analog output pairs 1/2 I or 3/4, it will also affect the level of the first and second headphone outputs, respectively.
Connecting the Analog Outputs
Connect the rear-panel line outputs 13 to a mixing console, amplifier or powered monitors. By default, analog output pair 1/2 is controlled by the front-panel Master Volume knob 6 , however, this knob can be assigned to control other outputs pairs through the ProFire 610 Control Panel.
! AUTION: Analog output streams that are not assigned to be controlled by the Master Volume C knob will be sent to the analog outputs at maximum level.
IP: To control the level of the main monitor mix without affecting the level at the headphone T outputs, assign the Master Volume knob to either analog outputs 5/6 or 7/8 and use those outputs for your main monitors. This prevents the Master Volume Knob from influencing the levels of headphone outputs 1 and 2 and effectively provides front panel volume controls for three unique stereo outputs. If you already have a way of controlling the main monitor mix level (e.g. through the use of an external mixer), another good use for the assignable Master Volume Knob is as an auxiliary send. Simply connect one of the analog output pairs to an outboard effects unit and assign the Master Volume Knob to the respective channels. Bring the outboard effects outputs back into the ProFire 610 interface using line inputs 3 and 4 as the auxiliary return and use the Master Volume Knob to control the auxiliary send level.

Software Control Panel

The ProFire 610 driver software provides a simple but powerful interface to connect with your computers Digital Audio Workstation software. The Control Panel provides five independent multi-channel mixers, featuring six input channels sourced from the physical inputs, as well as ten output channels from your audio software. Each mixer is routed to its own pair of hardware outputs, allowing five unique mixes to be created from any of the hardware inputs and software returns. The ProFire 610 Control Panel is installed in your system when you complete the driver installation procedure. To open the Control Panel: W indows XP/Vista users: A small M-Audio logo will be placed in the system tray, generally located at the bottom of your Windows desktop. Double click this icon to open the Control Panel. ac OS X users: The ProFire 610 Control Panel can be found in System Preferences, under Other. M NOTE: he ProFire 610 Control Panel can also be opened from an ASIO compliant T music programs audio setup page.

Mixer Tabs

This section of the User Guide provides a basic overview of the ProFire 610 monitor mixers and describes the various buttons, knobs, and sliders found on the mixer pages. Refer to the About Overdub Recording and Monitor Mixing section of this guide for an in-depth tutorial of how to set up and use the monitor mixers. Each Mixer tab contains sixteen mono input channels (which can function as eight stereo pairs) and one stereo master mix output channel. Each mixer channel strip contains (from top to bottom): level meter, pan, mute, solo, and level fader. Each adjacent pair of channels also shares a stereo link button. Each of these features is discussed in detail below.
The first six channels (on the left side of the mixer) correspond to the hardware inputs of the interface (i.e., analog inputs 1-4 and S/PDIF L/R). To the right of the hardware inputs are the ten software return channels that correspond to the outputs of your audio software. The remaining two channels (on the right side of the mixer) control the mixed output of the selected Monitor Mixer. The Control Panel features five mixer tabs along the top of the window (Analog Out 1/2, 3/4, 5/6, 7/8, and S/PDIF Out L/R). Use these tabs to select the output for which youd like to create a monitor mix. For example, select the Analog Out 7/8 tab to create a monitor mix that routes to analog outputs 7-8. Note that the two headphone outputs on the front panel of ProFire 610 correspond to Analog Outputs 1/2 and 3/4, respectively. For example, if you would like to create a monitor mix for second headphone output, use the Analog Output 3/4 tab.
IP: The first five tabs of the Control Panel (e.g., Analog Output 1/2, 3/4, 5/6, 7/8 and T S/PDIF Output L/R) can be renamed by double-clicking on the tab. This allows you to select a customized title for each monitor mix. For example, if the bass player has a headphone mix playing back through Analog Outputs 3-4, this tab can be labeled Bassists Mix. Note that renaming a Control Panel tab only changes the name in the Control Panel application itself; tab name changes do not affect your audio application in any way. Level Meter Each channels level meter will display the corresponding channels input or output level. Each meter offers an indicator to display recent level peaks. The peak indicators hold time can be configured through the Peak Hold setting in the view menu. This menu is described in the Additional Functions section of this guide. Pan The pan control routes each channel to the left or right output bus. Double-clicking, Alt-Clicking (Windows) or Option-Clicking (Mac) on a pan knob will center the knob. Mute Clicking the mute button will mute the associated channels output. The button will illuminate to indicate that the corresponding channel has been muted. Alt-Clicking (Windows) or Option-Clicking (Mac) on a mute button will enable/disable the mute function for all channels within the currently displayed mixer. Solo Clicking the solo button will solo the associated channels output. The button will illuminate to indicate that the corresponding channel has been soloed. All other channels will be muted, except any other channels where the solo button is active. Alt-Clicking (Windows) or Option-Clicking (Mac) on a solo button will enable/disable the solo function for all channels within the currently displayed mixer. Stereo Link Clicking the stereo link button causes both of the corresponding adjacent channels to be controlled by either channels fader and mute/solo buttons. Alt-Clicking (Windows) or Option-Clicking (Mac) on a link button will link/unlink all channels within the currently displayed mixer.

Level Fader

The Level Fader controls the output level for its corresponding channel. Double-clicking or Alt/Option-Clicking on a channel fader will set the fader to unity gain. Channel Name The name displayed at the bottom of each channel strip can be changed by clicking on the field. Once you have entered a new name, press the enter/return key to confirm the new channel name. Note that changing channel names only affects the appearance of the channel names within the Control Panel mixer tabsthis feature does not affect your audio application in any way. Also note that renaming a channel in one mixer tab results in the new name appearing in all of the remaining mixer tabs. IP: Once you have finished naming a channel, pressing the tab key allows you to immediately T jump to the next channel and begin naming it. This lets you name all of the mixer channels quickly.

Settings Tab

The Settings window provides controls for various ProFire 610 hardware and synchronization settings. Note that the Control Panel provides separate drop-down menus for hosted and standalone modes. Hosted mode (i.e., when the interface is used with a computer) is the most common use of ProFire 610 whereas standalone mode allows the interface to be used without a computer. Both sets of drop-down menus are covered in this section. For more information about standalone mode, refer to the Standalone Operation chapter later in this guide. Hosted Mode Sync Source This drop-down menu lets you select the digital synchronization source of the interface when ProFire 610 is in Hosted Mode. The menu selects between ProFire 610 internal sync or external sync via an incoming S/PDIF signal.
Windows only: Buffer Size drop-down menu.

AHosted Mode Sample Rate

T his drop-down menu sets the sample rate of ProFire 610. Note that when using the interface with an ASIO or CoreAudio application, the sample rate can also be determined by your audio application. This parameter may not be editable from within the ProFire 610 Control Panel if your audio application is running. In this case, any changes to the sample rate must be made through the audio application itself. If the application does not provide a way to set the sample rate, quit the application, then change the sample rate through the ProFire 610 Control Panel. I f ProFire 610 is set to External sync, this menu will display the current incoming sample rate, and selection will be disabled. If the unit is set to External sync and an error is detected in the incoming sample rate, the field below the menu will display one of the following two messages: U nsupported an unsupported sample rate is detected Unlocked no valid clock source is detected

If External sync is selected and a sync error is detected, the Power LED 8 will blink.
Mixers Active at Sample Rates Above 96 kHz
When operating at sampling rates of 176.4 or 192 kHz, ProFire 610 can use two of its available Monitor Mixers. These two drop-down menus allow you to select which two mixers will remain active at sampling rates above 96 kHz. For example, if you would like to use the Analog Out 1/2 and S/PDIF Out L/R Monitor Mixer tabs, select them from the Mixer 1 and Mixer 2 drop-down menus. Note that when operating at sampling rates of 176.4 or 192 kHz, signals can still be sent to outputs that are not selected in these drop-down menus. However, these outputs will not feature any monitor mixing capabilities (i.e., the outputs of your audio software will be routed directly to the output and you will not be able to modify your signals before they reach the physical output ports). Master Volume Knob These checkboxes determine which analog output pair(s) will be affected by the Master Volume knob 6 on the front panel of the interface: If a box is checked, the volume level of its corresponding outputs will be controlled by the Master Volume knob; if a box is left unchecked, the outputs will play at full volume regardless of the position of the Master Volume knob. This feature gives ProFire 610 a great deal of flexibility in how it can be used. For example, in multi-channel surround mixing scenarios, you can use the Master Volume knob to simultaneously set the level of all speakers by checking the outputs that are connected to your speakers. On the other hand, if you are mixing in stereo using outboard equipment (i.e., compressors, reverb modules, etc.), you can use the Master Volume knob to set the output level of the main outputs (connected to your speakers) while allowing the additional outputs (that are connected to your external equipment) to remain unaffected. This will let you use the Master Volume knob to set the loudness level of your speakers without affecting your external gear. Note that the Master Volume Knob settings remain active even if the interface is used in Standalone Mode. For example, if the Master Volume knob is assigned to control analog outputs 1-2 in hosted mode, the Master Volume knob will continue to control the levels of analog outputs 1-2 when ProFire 610 is used as a standalone device.
! ARNING: Unchecking one of the Master Volume Knob boxes allows its corresponding W outputs to play at full volume (i.e., without any attenuation). This may result in very loud signals being sent to your speakers, headphone amplifiers, or other equipment. Be mindful of your outgoing levels anytime you uncheck one of these boxes to avoid potentially damaging your equipment (or hearing). If you wish to leave these boxes unchecked in order to allow full, unattenuated signals to play through the interface, it is strongly recommended that you have an external provision for controlling your levels (such as an external mixer).

IP: Keep in mind that it is always possible to convert from one format to another with T little or no audible degradation in sound quality. However, it is not possible to raise the fidelity of your already recorded files by increasing the sample rate or bit-depth. Therefore, if you are not sure about what rate to work at, try to use higher sample rates and bit-depths if your computers hard drive and processor allow you to work at these rates.
In most cases, you can set the sample rate and bit depth of your project from within the audio application itself. This configuration varies from program to program, but these settings are usually found in the Setup or Project Setup menus of your program. If your audio application does not have a configuration page or does not have provisions for changing sample rates, use the ProFire 610 Control Panel to make these changes. You may need to close your audio application before the Control Panel allows you to make any changes. NOTE: f you are recording or playing back to an external digital device through the I S/PDIF ports, be sure that you have set up proper clocking. Clocking is covered in detail in the Digital Clocking section of this guide.
About Overdub Recording and Monitor Mixing
Much of the popular music that you hear today is created using a method called overdub recording. Overdub recording allows artists to record their music while listening to previously recorded parts of the song. For example, a vocalist may record his or her parts while listening to the previously recorded guitar, bass, and drum parts in his/her headphones. This method is popular because each recorded part is completely separate from the other parts and can be more easily edited and mixed into a polished song. For example, if the guitarist is not happy with the solo, it is possible to edit problematic notes, re-record the entire solo, or even splice together the best parts of multiple takes to create one seamless performance. This kind of detailed editing is generally not possible with live recording situations in which all sounds are captured at once. To record overdubs, each artist must have a monitor or cue mix sent to his/her headphones. This mix contains the previously recorded tracks combined with the live signal that is being recorded. For example, the vocalist would need to hear the guitar, bass, and drum tracks along with his/her own vocal performance as it is being recorded into the computer. ProFire 610 allows you to create up to five stereo monitor mixes using the first five tabs of the Control Panel. Each tab controls a stereo mixer with 16 inputs (six hardware inputs plus ten outputs from your audio software). Each tab routes signals to a separate pair of outputs as shown in the following table:

Tab Name: 2 Analog Out 1/2 Analog Out 3/4 Analog Out 5/6 Analog Out 7/8 S/PDIF Out L/R
The output of this tab is routed to: Hardware Output 1/2 and Headphone Output 1 Hardware Output 3/4 and Headphone Output 2 Hardware Output 5/6 Hardware Output 7/8 S/PDIF Output
ab names can be changed by double-clicking the title and entering a new name. Tabs with customized T names will appear differently than the example scenarios in this guide.
Using the Monitor Mixer To use the ProFire 610 Monitor Mixer:
1. Select the tab that corresponds to the hardware outputs to which you would like to send your monitor mix. For example, if you wish to create a mix that routes to analog outputs 7/8, select the Analog Out 7/8 tab. IP: Keep in mind that the first and second headphone outputs are hardwired to analog T outputs 1/2 and 3/4. If you would like to route your monitor mixes to the first or second headphone outputs, select the Analog Out 1/2 or Analog Out 3/4 tabs, respectively.
2. Adjust the level faders for the hardware input and software return channels to create a comfortable monitor mix for the listener. he six channels on the left side of the mixer represent the live hardware inputs. For example if T you have connected a microphone and guitar to the first two inputs, signals from these devices will appear on channels one and two of the mixer. The ten Software Return channels correspond to the outputs of your audio application.3 he last two channels on the right side represent the monitor mixers master outputs that are sent T to the mixers associated hardware output pair (on the rear-panel of ProFire 610). eep in mind that this mixer is for monitoring purposes only. All signals received at the K hardware inputs are also sent directly to the recording application without being altered. The Monitor Mixer receives duplicates of these input signals to allow you to create a nearzero latency monitor mix. Changes made to the monitor mixer do not affect your recordings (or your audio software), since the Monitor Mixers output is not actually being recorded. example, if the singer would prefer to not hear guitars while recording, the guitar For channel of the singers monitor mixer can simply be muted without affecting the recording application in any way. 3. Use the pan knob to adjust the position of a sound between the left and right channels. Note that double-clicking a knob will center it.
4. you are routing signals to Headphone Outputs 1 and 2, make sure the Headphone Level Knobs 4 are If set properly. Alternatively, if you are routing monitor mixes to external headphone amplifiers, make sure those amplifiers are set properly.

W hen selecting output channels 1/2 from your audio application, the signal is not sent directly to the physical hardware outputs on the rear-panel of ProFire 610; The signal is first sent to the Analog 1/2 tab of the Control Panel. By default, the monitor mixer on this Control Panel tab then passes the unaltered signal on to hardware outputs 1/2. However, this tab gives you additional control over signals sent to hardware outputs 1/2. Y ou can use the faders, pan knobs and other controls on the Analog 1/2 tab to add and blend signals from the physical inputs 1-6 and from the remaining ten software return channels and create a stereo mix that is then routed to the rearpanel hardware outputs 1/2. T he same principle applies when selecting output channels 3/4, 5/6, 7/8, or 9/10 from your audio application. These signals are sent to their respective Control Panel tabs Analog 3/4, Analog 5/6, Analog 7/8, and S/PDIF Out L/R, mixed with other signals if desired, and then routed to their respective analog output pairs 3/4, 5/6, 7/8, or the digital S/PDIF output.
NOTE: hen using the ProFire 610 monitor mixer to create low latency monitor W mixes, be sure to mute your DAW applications recording channels (or, if possible, turn off the applications monitor mixing functionality altogether) to prevent two separate cue mixes from being created (this can cause undesirable effects such as phasing and slap-back delays). Conversely, if you wish to use your applications own monitor mixing capabilities, you will need to bypass the ProFire 610 monitor mixers to prevent doublemonitoring from taking place. This can be done by simply muting the input channels of the monitor mixers that you are using.

Standalone Operation

In addition to operating as an audio interface for your computer, ProFire 610 can also operate without a computer in standalone mode. In Standalone mode, ProFire 610 functions as an analog-to-digital (A/D) and digital-to-analog (D/A) converter. Analog inputs 1-2 are passed through to analog outputs 1-2 while simultaneously being converted to digital and sent out of the S/PDIF output. The S/PDIF input is converted to analog and sent out of analog outputs 3-4. To enter Standalone Mode, power down your computer and the ProFire 610 interface, disconnect any FireWire cables attached to the FireWire Connectors 11 , and switch on the interface. Keep in mind that all Standalone Mode settings must be made while the interface is still connected to a computer (i.e., ProFire 610 settings cannot be modified while the unit is operating in Standalone Mode). The parameters in the Standalone Mode section of the Settings tab of the Control Panel determine how ProFire 610 will function while the interface is operating in Standalone Mode. This is a useful feature as it allows you to set the Standalone Mode settings independently from the hosted settings. This saves you from having to reconfigure the Control Panel each time before you use the interface in Standalone Mode. For more information on configuring ProFire 610 for standalone operation, refer to the Settings Tab section of this user guide.

Digital Clocking

Your computer-based DAW stores and manipulates music as digital samples. Those samples are sent to and from your DAW as snapshots of data. These snapshots are all the same size16-bit or 24-bit, depending on your selected resolutioneach with a beginning and an end, and are sent in sequential order (i.e., one after the other) as a stream of data. Think of this data stream as a sentence, made up of a series of words of identical length. The rate at which these words are transmitted (i.e., how many samples are transmitted each second) is known as the sample rate of the device. Audio CDs have a sample rate of 44,100 samples per second (known as 44.1 kHz) whereas certain high-end professional audio devices (such as ProFire 610) support very high sample rates (up to 192 kHz) for high audio fidelity. Precise, accurate timing in sending and receiving those words is critical. Each device in your interconnected digital world must share the same timing in order to communicate correctlythat is, their clocks must be synchronized. This synchronization is achieved by designating one device as the timing master, and all other connected devices as slaves, locking the slaves to the master. Only one device in the chain can be the master, and all other devices must slave to that master. All devices must be running at the same sample rate as well. For example, if the master is running at 44.1 kHz, no other device should be set to any other sample rate. Word Clock is an important part of digital studios but is often overlooked by engineers new to digital recording. It is crucial to set up Word Clock correctly because without precise synchronization between your digital devices, your digital audio signal will be filled with clicks, pops, and white noise, or may not play at all. The following scenarios provide practical digital synchronization examples and setup tips.
Scenario 1: ProFire 610 as Clock Master
By selecting internal as the sync source in the Control Panel, you designate ProFire 610 as the clock master. You will then need to select external (or slave on certain devices) mode on your digitally connected device(s). This is usually an internal menu setting on the external device.

Troubleshooting

ProFire 610 has been designed to give you high performance and professional-quality audio on a wide range of systems and operating conditions. However, there are a virtually limitless number of operating scenarios, any of which could affect your systems performance. While this section cannot cover all possible issues you may encounter, we would like to offer you some suggestions for dealing with common problems. In general, it is recommended that you avoid connecting too many FireWire devices to your computer. FireWire is a dependable high-bandwidth protocol that is ideally suited for digital audio. Nonetheless, its important to remember that audio and multimedia streaming places considerable demands on both your processor and the FireWire bus. Although it is theoretically possible to chain multiple FireWire devices in series, doing so may result in audio recording and playback issues.
If you are having trouble getting audio into or out of your computer, please check the following: If you have no sound: heck to see if the device drivers are properly installed. In Windows, go to the Control Panel and C double-click the System icon (under Performance and Maintenance if youre in Category view). Select the Hardware tab and click the Device Manager button. Click the plus sign (+) next to Sound, Video and Game Controllers, and locate the ProFire 610 listing. If you see a question mark or exclamation point next to it, or if you dont see it listed, you may need to reinstall the driver software. ake sure your audio software has been set up to use ProFire 610. Open your applications audio settings M page and check to see if the correct ASIO, WDM, or Core Audio drivers have been selected. f youre certain ProFire 610 is correctly installed and configured for your audio software, check your signal I path. Make sure your inputs are routed correctly by verifying that your application is receiving audio signal. Make sure your outputs are routed correctly so that your signal is sent to your headphones, amp and/or monitors. heck your audio connections to make sure everything is plugged in correctly. C Check the Signal/Clip indicators 2 to see if input signal is present. heck the Control Panel to verify that the output volume levels are turned up, and that signal is present in C the input meters. heck to see that the power button is enabled, and that the FireWire cable is connected to the unit and C the host computer. If you are connected to a 4-pin FireWire port, or if your computer doesnt provide sufficient FireWire bus power, make certain the external power supply is connected.

If you are trying to record a digital input and have no sound: f the Power LED Indicator 8 is flashing, this means that the interface is unable to detect a proper clock I source. Open the Control Panel and select S/PDIF as the Host Mode Sync Source on the Settings tab.
If you are experiencing clicks and pops in your recordings:
hen clocking to an external digital device, make sure the input source on the Settings tab of the Control W Panel is set to External - S/PDIF. See the section about Word Clock for more information. ake sure your input levels are not too high, as this can cause distortion and clipping. Check the input M level meters in your audio application. f you have connected ProFire 610 to a computer through a FireWire hub, try connecting the interface I directly to your computer to see if the problem resolves. ertain PC motherboards feature network adapters that may conflict with the FireWire port and result in C streaming issues for attached FireWire devices. Try disabling your network interface adapter (NIC) to see if the issue resolves. This can usually be done through the system BIOS or the Windows Device Manager. Please refer to your Windows or motherboard documentation to learn how to do this. indows XP/Vista Users: Try increasing the ProFire 610 buffer size. Larger buffer sizes will increase W latency but will reduce the demands placed on your computer and may improve audio streaming. Buffer size settings can usually be changed through your audio applications setup or preferences menu or the ProFire 610 Control Panel.
