Using Personal Mixers

It is possible to create an audio distribution and personal monitor system using any combination of Aviom AN-Series and Personal Mixer products, including the A-16II, and A-16R. When referring to the use of the personal mixers in a system in general, the terms A-16II Mixer or Personal Mixer are used to describe a case where a standard A-16II Personal Mixer or a rack mounted A-16R Personal Mixer (with/ without the optional A-16CS Control Surface) can be used.

Cat-5 Cables

In most cases Cat-5e, Cat-6, and Cat-6e cables can be interchanged. When speaking about interconnections between components in a system, the term Cat-5 is used generically to indicate the use of any of the applicable cable types.

A-Net Distributors

The A-16D and A-16D Pro A-Net Distributors are referred to generically as A-Net Distributors.

Package Contents

Check the contents of the shipping box carefully before making connections and continuing with installation. The A-16II Personal Mixer box contains: One A-16II Personal Mixer DC Power supply for the A-16II Personal Mixer One Cat-5e interconnect cable User documentation Also included within this document is a Warranty registration page.

About A-Net

The Pro16 version of A-Net is a high-speed data transmission protocol capable of sending and receiving high-quality digital audio using readily available Cat-5 cables. A-Net is a proprietary technology developed by Aviom.
A-Net is based on the physical layer of Ethernet, a Local Area Network (or LAN) technology. This provides A-Net with a mature and robust base on which to build. However, it is important to note that A-Net devices are not compatible with Ethernet devices. As used in the Pro16 series products, the A-Net signal carries sixteen channels of digital data from the Pro16 input module (AN-16/i, AN-16/i-M, or compatible console card) to each A-Net device connected to the system. Some of the benefits of using A-Net to transmit digital audio are: Virtually no latency No ground loops Easy cabling using readily available components An unlimited number of A-Net devices can be used in a system Ease in spanning long distances between system components P Note: While the Cat-5e cables and connectors used on your Aviom products look like typical computer Ethernet network connections, do not connect computers, routers, or other home and business networking equipment to your Aviom products.

Compatibility with Pro64

Many Pro16 products can be connected to a Pro64 A-Net system with the addition of the ASI A-Net Systems Interface. The ASI translates Pro64 A-Net data into Pro16 data and separates the 64-channel Pro64 stream into up to four 16-channel Pro16 outputs, depending on the Pro64 sample rate being used. Only Pro16 devices that have an A-Net In port such as Personal Mixers, A-Net Distributors, and output modules are compatible with Pro64 and the ASI. Pro16 input modules and console cards cannot send their data into a Pro64 network.

System Connections

A single Cat-5e cable is required to connect each A-Net compatible device in your system. Connect a Cat-5e cable from the A-Net Out jack on the input module to the A-Net In jack on the first Personal Mixer. Connect additional A-16II Personal Mixers with a Cat-5e cable from the A-Net Out jack on the first Personal Mixer to the A-Net In jack on the next Personal Mixer. (Repeat this process for each additional Personal Mixer unit in your system.) Connecting the Personal Mixers in this manner is referred to as a series connection, also known as a daisy chain. Any combination of A-16II and A-16R Personal Mixers as well as other Pro16 output devices can be used to create a system.

Connect A-Net Out to A-Net In to make a daisy chain. A-Net can also be distributed in parallel by using an A-Net Distributor. This can eliminate daisy chained A-Net connections.

Audio Connections

Plug headphones, wired or wireless in-ear monitors (IEMs), powered floor monitors, or spot monitors into the A-16II Personal Mixers Headphones/Line output jack on the rear panel of the Personal Mixer. Before powering up the system, turn the Master volume control on the Personal Mixer to its minimum setting (full left) to ensure that unwanted highvolume audio is not accidentally sent into your monitors when the system is powered up. The Master volume control is in the upper right section of the Personal Mixer, next to the Bass and Treble controls.

Labeling the Channels

The A-16II Personal Mixer has a convenient label strip (also called a scribble strip) right on the front panel. Use a non-permanent marker to write the name of the instrument or audio source appearing on each channel in the label area. Optionally, apply removable artists tape to the label strip prior to labeling each Personal Mixer. A convenient MS Excel format label strip template, available on the Aviom website, can be used to print out text labels for the A-16II from a computer. P Note Use only non-permanent marking devices on the label surface to avoid permanently marring the surface.

Powering Up

As when powering up any audio gear, its best to power up all system components in the safest possible order to minimize the risk of damage to system components and your hearing. Start by turning on devices such as mic preamps, mixers, keyboards, and effects processors. Follow this by turning on power amps, or anything that applies power to speakers, headphones, etc. In the case of the Personal Monitor Mixing System, you should power up your main audio mixer, effects devices, and keyboards first. Follow this by powering up your A-Net input module and then all connected A-16II Personal Mixers. Lastly, turn on any power amps, powered monitor speakers, in-ear monitors, etc. that are part of the monitor system.

A-16II Features

This section describes the controls, modes, and functions of the A-16II Personal Mixer. The basic components of the front panel include: Sixteen lighted channel buttons (they also function as the Preset memory locations) Channel label strip Recall button Group configuration and edit button Solo and Mute buttons Pan and Volume knobs Bass and Treble tone controls Master Volume control A-Net Active LED indicator

The A-16II front panel

Operational Modes
When using the A-16II Personal Mixer, you will be in one of the following modes: Mix Mode Here you can change channel and mix settings such as volume, mute, and panning; youll spend most of your time in this mode. Recall Mode Activated by the Recall button, the row of sixteen channel buttons are used to select one of the sixteen available mixes saved as Presets.
Group Mode Used when creating Groups or editing existing Groups. This is activated by pressing the Group button. The channel Select buttons are used to add or delete channels from a Group. Solo Mode When the Solo button is pressed, the selected channel (or Group) is audible while the rest of the mix is muted. Save Mode This mode is activated by pressing and holding both the Recall and Group buttons. When both buttons are held down, the Save Mode is active. Pressing any numbered button while still holding this button combination will save your current mix to that Preset location.
P Note: A Preset is saved when the numbered button is released.

Global Controls

The three knobs in the upper right section of the A-16II Personal Mixer affect your overall mix volume and tone directly. The Bass, Treble, and Master volume controls are always active, regardless of the state of the current mix or selected Preset. These are analog controls and their settings are not stored as part of a mix preset.

Tone Controls

Use the Bass and Treble controls to change the overall balance of bass or treble frequencies in your mix. These controls affect the entire mix, not the individual channels.
The global Bass, Treble, and Master volume controls The default position for the Bass and Treble knobs is at 12 oclock. To add more
low frequencies to your monitor mix, turn the Bass knob to the right of the 12 oclock position. To remove lows, turn the knob counterclockwise past the center. To change the high-frequency content, follow the same procedure; turn the Treble knob right to add highs, left to diminish them. The Bass and Treble EQs in the Personal Mixer are both shelving type. There is +/-12dB of cut or boost available for each.

Personal Mixer Rear Panel
On the rear of the Personal Mixer you will find the A-Net connectors, the power supply input, and the audio output.

A-Net Connectors

There are two A-Net connectors on the rear of the Personal Mixer. The A-Net In jack accepts: the A-Net signal coming from the A-Net input module if the Personal Mixer is the first Personal Mixer in the system, or the A-Net signal coming from the Out jack of another Personal Mixer, or the A-Net output from an A-Net distributor product
A-Net connections The A-Net Out jack is used to connect another Pro16 A-Net device. This will send the same sixteen audio channels being processed by the input module to the additional device so that another unique monitor mix can be created. An unlimited number of A-Net devices can be connected in series using this method.

DC Power Input

Connect the DC power supply to the jack on the rear of the Personal Mixer. Use only power supplies designed for your Aviom products.

Audio Outputs

The audio outputs on the rear of the A-16II Personal Mixer can be used with headphones, in-ear monitors, powered speakers, or any other device that can accept a line level audio output. Stereo, dual-mono, and mono outputs are available by using the appropriate cables.
The headphone/line output of the A-16II has a TRS stereo output. Stereo The TRS outputs on the Personal Mixer are stereo. Any pair of stereo headphones or earphones can simply be plugged into the jack. To connect a set of stereo speakers (studio monitors or stage speakers), use a stereo to dual-mono adapter to split the stereo signal into separate left and right mono signals. Then connect a standard mono cable to the audio input of the left and the right amplifier for the speakers. Mono To use a mono amplifier, powered speaker, etc., connect a standard unbalanced TS audio interconnect cable (tip and sleeve guitar cord type) from the audio output on the Personal Mixer to the audio input on your mono device. To connect to a mono input on a device that has an XLR input connection, you need to use a cable that has a tip-sleeve unbalanced jack on one end and an XLR on the other. P Note: Using a tip-ring-sleeve jack to XLR cable will cause the left and right channels to be summed, resulting in a loss of level.

Setting Channel Volume

When you change the volume of a channel on the Personal Mixer, the LEDs in the Volume section of the mixer surface will indicate the level in real time. When a new channel is selected, its current volume is instantly indicated on the LEDs. When no LEDs are lit, channel volume is at its minimum setting.
The Pan and Volume Controls for the selected channel To make changes to a channel: Select a channel by pressing its numbered buttonthe buttons upper LED will light. Rotate the Volume knob to the right to increase the volume, to the left to lower the volume

Setting Pan

The Pan indicator is made up of five LEDs. The center LED is green. The LEDs on either side of center are red. As you turn the Pan knob, the LEDs will light in various combinations. At either end of the display only one LED will be lit to indicate that the channel is panned full left or right. When using stereo linked channels, the LEDs light in different patterns, using a pair of LEDs on either side of the display to indicate the width of the stereo
field. When the stereo image has been collapsed to mono, only the center green LED will be lit. In this case the stereo input will be heard as mono.
P Note: If you have connected the output of the Personal Mixer to a mono audio system or speaker, the pan position is irrelevant. Continue this process of setting volume and pan until all the channels have been added to the mix. At this point you should have a basic mix playing in your headphones, IEM, speakers, etc. You can continue to make changes in real time as your needs require. Remember that changes to channel volume and pan setting affect the selected channel only. The selected channel always has its red LED lit.

Linking Channels

For stereo input sources such as keyboards, CD players, submixes, etc., Pro16 input modules provide a convenient method of controlling these twochannel sources. Its called a Stereo Link. Linking two channels is done from the input module. Each pair of inputs has a corresponding Link switch. When the switch is positioned to the left, the two channels are independent. When the switch is moved to the right, the channels become linked. Only adjacent channels can be linked (channels 1 and 2, channels 3 and 4, etc.). When channels are linked, they act as one source on the A-16II Personal Mixer. When you select either of the two linked channels on the Personal Mixer, both LEDs will light, indicating that they are linked at the input module. Volume changes affect both channels simultaneously. Channels that are linked at the input module will appear linked on every Personal Mixer connected to the system. You can link or un-link channels as needed, even while audio is running through the system. All connected Personal Mixers update immediately.

The Spread Control

When two channels are linked, they no longer have separate pan controls. With the channel link comes a new feature, called Spread. The Spread control varies the stereo image of the two linked channels from full stereo to mono. This allows you to position stereo sources in your mix by controlling the width of the stereo image. Spread changes the panning of the left and right channels simultaneously. Instead of having two channels panned 100% left and right, Spread allows
the channels to be panned to 60% left and right, for example.
The Effect of the Spread Control
Spread turns this: into this, for example: When you adjust the Pan control with a stereo-linked channel selected, the Pan LEDs show the width of the stereo spread that is currently set. Multiple LEDs light to indicate the compression of the image from full stereo to mono.
The Mute and Solo Functions

Solo a Channel

While working with a mix, you may want to listen to a particular channel by itself to check a part, locate or solve a problem, confirm a pan location, etc. To do this you can use the Solo mode. Solo lets you listen to the selected channel alone without disturbing the rest of the mix. Two types of Solo mode are available; one functions on a channel by channel basis, the other (called Held Solo) remains in force until the user exits it. Solo mode works on the currently selected channel or Group. To use Solo, first select the channel you want to hear alone. Its red button LED should be lit. Now press the Solo button, found in the pair of buttons in the upper right corner of the Personal Mixer. The channel is now heard solo. You can make changes to volume and panning when a channel is in Solo mode. All changes happen immediately. Consider Solo mode as a temporary state only. You cannot save a Preset with a channel in Solo mode. Only one channel, linked pair, or Group can be in solo at a time. To exit Solo mode, simply select another channel or press the Solo button again to exit. To select a different channel for auditioning in Solo mode, remember that you must first select a channel and then press the Solo button to enter Solo mode.

P Note: Solo mode will temporarily override a mute. This guarantees that you will always hear the channels you solo. When you exit Solo mode, the channels are returned to their previous state.

Creating Groups

When you need control over more than just a stereo pair of channels as described earlier using the Link function, you can use the Group function to control multiple channels. Up to three Groups can be created and saved per user Preset. This means that every Personal Mixer can have up to forty-eight different Groups stored by using all sixteen user Presets. A Group can consist of any number of channels, but Groups cannot overlap. That is, one Group cannot contain channels that are part of another Group. Mono or linked stereo channels can be part of a Group. As you create a Group, the channel volume and pan settings of each channel added to a Group are retained. This helps to keep the overall blend of channels that are part of a Group even while you adjust the Groups overall volume. The Volume now control changes the overall level of the Group. Some examples of Groups in use: A Group allows background vocal parts from multiple singers to be adjusted together. All the drums in a live drum kit can be combined to a single stereo mix for easy adjustment for the guitar player, while the drummer retains individual control over each drum in his mix. Horns and woodwinds can be controlled together. Rhythm section instruments can be combined into one source. Creating and editing Groups is done in the Group Mode.
Press the Group button to create or edit a group. To create a Group: Start by selecting a channel that you want to be included in the Group. Press the dedicated Group button on the left side of the A-16II Personal Mixer. The red Group LED will begin to flash indicating that you can now edit the Group. Double-click the channel buttons to include a channel in the Group. Channels that are added to the Group will flash their upper red LED to indicate that they are now part of the Group. To exit, simply press the Group button again. The Group LED goes out and you are returned to your current Preset and live mix. In the current Preset, you will now see all channel LEDs associated with a Group light whenever you press a channel button that is included in your Group. The channels now behave as one. P Note: Remember to save the edited Preset if you want to recall the Preset with the new Group settings later.

Verify a Mix Memory Location
When creating and editing mix Presets, it is useful to know which Preset was the last one to be stored in order to avoid overwriting Presets accidentally. When preparing to save a mix in the A-16II, the software will display the last mix Preset that was recalled when the Recall and Group buttons are held simultaneously. The red LED in the channel button that corresponds to the last recalled Preset will light as long as these two buttons are held.
P Note: Remember to save your new mix to a memory location before turning the monitoring system off.

Applications

This section describes how to set up and use the Pro16 Monitor Mixing System in a variety of contexts. Pro16 mic- or line-level input modules such as the AN-16/i and AN16/i-M can be used as well as console cards from Aviom and third-party manufacturers. Most of the applications described below apply equally to analog and digital consoles. However, this document cannot cover third-party digital console cards and the configuration of the consoles that can accept them. Refer to the user documentation for the digital console for information about using and assigning direct outputs, aux sends, etc., to a Pro16 A-Net console card used as the input module for a monitor mixing system.

Console Direct Outputs

The direct output of a live or recording console allows you to take an exact copy of an input channels audio and patch it into the Pro16 input module. A typical consoles direct output point is right after the input (pre-fader, preEQ), meaning that changes made on the console as far as effects, EQ, etc., do not affect the sound of the direct output. Aviom input modules can accept up to sixteen direct output signals as sources. You can use balanced or unbalanced cables to connect audio, depending on the configuration of your mixer. Follow these steps to create a monitor system with direct outputs: Connect a balanced or unbalanced cable from the direct output jack on the mixing console to the first input on the Pro16 input module. Repeat this procedure for the other console channels you want to add to the monitor mix. Select an appropriate input level setting on the input module front panel (analog input modules only). Send audio into the Pro16 Monitor Mixing System. Select a channel on the Personal Mixer and set the volume and panning. Save the mix as a Preset. At this point you can use the mix as is, or fine tune it by adding Groups, linking channels, etc.

Monitor with the effect: Remove the cable from the audio In jack of the Pro16 input module. Plug it into the input of the effect. Connect a cable from the output of the effect to the input module In jack. Leave the cable already connected to the input module Thru jack as it is. It completes the loop and sends the processed signal back to the mixing console. You can wire much of the same functionality described above into a patch bay for more permanent installations. Remember to use the same type of cables and patch baysbalanced cables with balanced patch bays, unbalanced cables with unbalanced patch bays.

Studio Cue System

In the studio, the flexibility of the Personal Mixer will give performers more control of their headphone cue mix. At the same time it allows the recording engineer to spend less time fussing with the cue mix and more time making the recorded tracks sound great. Making a cue mix from a recording console is essentially the same as when using a live mixing board. If your recording console or DAW has direct outputs or unused auxiliary sends, you can use the same techniques as described for live audio monitor mixes.

Playback Monitoring

In the studio, performers also need to listen back to tracks they have just recorded. If each performer is using a different mix while recording, playback of the track will be different in each set of headphones.
If you can dedicate two inputs on the Pro16 input module for playback, you can easily provide the performers with a high-quality playback of the track they have just recorded. Heres how to set it up: Set aside the first fourteen channels of the Pro16 input module for audio tracks to be sent to the performers as a cue mix. The remaining two channels (15-16) are reserved for the stereo mix that the engineer creates in the studio. Connect cables from the mixing console for monitoring the fourteen performer channels as described previously from direct outputs, aux sends, etc. Patch the output of the stereo mix that you want the performers to hear into the remaining two input module inputs. The idea is that you will create two Presets on the Personal Mixers for the performers. The first is their standard cue mix. It uses fourteen channels; the last two channels, 15 and 16, are muted. They can change it as needed while they work. Save this as Preset #1 in the Personal Mixer. The other Preset is the exact opposite. The performers fourteen cue channels are muted and the two channels containing the engineers playback mix are on. Save this as Preset #16 in the Personal Mixer. For the example, lets assume that channels 1 through 14 are used for performer cue playback. Channels 15 and 16 will be used to play back the recorded track. When the musicians are cutting tracks, have them select Preset #1. Record tracks as usual, with each musician listening to their personal customized cue mix. When you want to listen back to a recorded take, have the performers switch to Preset #16. They now hear the engineers mix. All players hear the same mix, that the engineer can control as needed. Of course the players can create additional cue mixes and save them to the remaining empty Preset locations 2 through 15 as needed.

Adding Effects to a Monitor Mix
Sometimes you may want to have reverb, delays, etc. sent into the monitor system. This works for live applications as well as for studio cue systems. There are two ways of accomplishing this: Patch the effects returns from the mixing console into the Pro16 input module via insert points if available. Connect the effects devices audio outputs to the Pro16
input module first and then use the Thru jack on the input module to complete the signal chain. In either case the performers can now decide how much of the effects return is required in their personal mix. And, they can save up to sixteen mixes with various amounts of effects in each.
Adding Live Ambience to a Monitor Mix
For performers using in-ear monitors in a live performance situation, it may be desirable to add some room ambience into the monitor system to help add a sense of space. This technique can be used with most live mixing consoles. All you need is a way to send the signal from one or more room mics into the Pro16 input module. A pair of mics on either side of a stage provides a stereo ambience signal that can be added as needed to a performers mix. If you are using direct outputs from channels to send instrument and mic signals into the input module, you need to dedicate two channels to the mics that are picking up the ambient sound. It is not necessary that these live mics be sent into the front of house mix.

Silent Session

There is no requirement that a mixing console be used with the Pro16 Monitor Mixing System, especially when you have an analog input module. It makes a great self-contained rehearsal environment for keyboard players, guitarists, and electronic drummers, etc. To set up a silent monitoring system: Connect the outputs from stereo keyboards to inputs on the Pro16 input module. If the keyboard player uses a sub-mixer, you can optionally connect the stereo output of the keyboard mixer to two inputs. Patch the output of a guitar amp simulator into a pair of inputs. Connect an electronic drum kits outputs into the input module. Set the stereo link switches on the input module for any stereo channel pairs.
