Introduction

Ensemble is a digitallycontrolled Firewire audio interface specifically designed for Apple Macintosh computers. From mic preamps to Mac Core Audio connectivity to headphone outputs, Ensemble includes all thats necessary for a highquality Macbased recording system. Ensemble includes several of Apogees Core technologies, including: SoftLimit Soft Limit is an analog peak limiting circuit that instantaneously and gracefully controls transient peaks, thereby allowing an additional 4 dB of headroom. Soft Limit may be engaged on all 8 Ensemble analog inputs. UV22HR UV22HR is Apogees industry standard dither algorithm for reducing the wordlength of a digital audio signal from 24 to 16 bits. UV22HR is also being employed to produce dramatically improved internet and computer audio content without increased file sizes or data rates. Apogee Sample Rate Conversion (SRC) Ensembles hardware sample rate conversion provides a high quality, flexible solution for working with digital audio hardware and software running at different sample rates. Ensembles sample rate conversion may be applied to a digital input (to convert an input stream to Ensembles sample rate) or to a digital output (to provide an output stream at a user selected sample rate different than Ensembles rate). Ensemble Requirements 1.Apple PowerMac 1.5GHz or higher, 512MB of RAM required, 1GB recommended 2. OS X 10.4.11 or 10.5 and above; OS X 10.5.3 or above highly recommended 3.

General Operation
Making Settings with Software Control Panels
All Ensemble settings are made from Apogees Maestro software Settings panel or Logic Pros Apogee Control Panel. Certain settings can be also be made from OS X audio control panels. Its possible to open multiple control panels simultaneously, as settings made on one control panel are mirrored on all others. Additionally, Mic Pre gain and Ouput level may be controlled from Ensembles front panel encoders, as described on the lower half of this page. What is Maestro? - Apogee Maestro provides the most complete control of Ensemble, including control of all Ensemble parameters, store/recall of configurations, expanded routing and 2 lowlatency mixers. Maestro may be used with any Core Audio compatible audio application. Please see the complete explanation of Maestros Settings panel beginning on p. 14 The Logic Pro Apogee Control Panel, found in Logic Pro under the Audio menu, provides control of all Ensemble parameters and store/recall of configurations. Audio Midi Setup (AMS) This OS X utility (found in the rootdrive/Applications/Utilities folder) provides control of Ensembles clock source, sample rate and output level. To set Ensembles output level using the Macs menu bar audio fader, set Default Output (in AMS) to Ensemble; OSX audio faders (including the menu bar fader) will then control the output selected on Ensembles front panel. For example, if the front panel 1 LED is lit, OSX audio faders control the 1 output level.
Making Settings with Ensembles Front Panel Encoder Knobs
Ensembles front panel encoders provide simple and immediate access to Mic Pre gain settings and Output levels. To use the left encoder to control mic pre gain: Select the mic pre gain to set by clicking the left encoder knob until the desired PRE LED is lit. Turn the encoder clockwise to increase gain or counterclockwise to decrease gain. The LEDs encircling the encoder indicate its position, providing a quick visual indication of level in the same fashion as a traditional knob.
To use the right encoder to control output levels: Select the output to set by clicking the left encoder knob until the desired LED is lit, and turn the knob as described above; by selecting MAIN, rear panel analog output levels may be set; by selecting either 1 or 2, the corresponding front panel headphone output level may be set. By pressing and holding the right encoder button for a few seconds, all analog outputs are muted. The selected output LED flashes to indicate muting.

Please see p. 16 to configure the MAIN and headphone outputs

Setting Sample Rate

To set Ensembles sample rate, choose the desired rate in your Core Audio compatible software application; Ensemble will set itself to this rate. If the application has no sample rate setting, open the OSX utility Audio Midi Setup, select Ensemble in the Properties For field and select the desired rate in the Format field.
Using 176.4192 kHz Sampling Rates
To operate Ensemble at a sample rate of 176.4-192k, its necessary to set I/O Allocation (found in Maestro under Tools>Settings>Settings tab) to either 10x10 or 8x8. As Optical I/O is not supported at these sample rates, their associated Firewire paths are disabled to conserve CPU bandwidth. After changing I/O Allocation, its strongly suggested to re-boot the computer and power the Ensemble off and then on.

Setting Clock Source

Ensembles clock source may be set from Maestro, Logic Pros Apogee Control Panel, or from OSXs Audio Midi Setup utility. When Ensemble is locked to an external source, Ensembles sample rate is still determined by the selection in software. Thus, the sample rate of the external source must be manually set to match the software sample rate. For example, if you want to open a session at 88.2 kHz but lock Ensemble to word clock from an Apogee Big Ben, you must manually set the Big Ben to 88.2 kHz.

Digital I/O

The availability of Ensembles digital I/O is based on the units sample rate and Optical I/O Format setting, as depicted in the chart below.

Analog I/O 8

Optical I/O

Coaxial I/O 2

44k1/48k 88k2/96k 176k4/192k
8 ADAT or 2 S/PDIF 4 SMUX or 2 S/PDIF none

Stand-Alone Mode

When Ensembles firewire connection is interrupted, the unit automatically enters Stand-Alone mode, whereby all current control panel, routing and mixer settings remain operational, despite the absence of a host computer. In Stand-Alone mode, the Status LED turns green and all front panel controls remain active.

Ensemble Routing

Unless routing is modified in Maestro software, all Ensemble rear panel inputs are routed via Firewire to the Mac, while all rear panel outputs are routed via Firewire from the Mac, as depicted on the next two pages.

Maestro Control: Settings - Settings
All Ensemble settings are made from Apogees Maestro Settings panel or Logic Pros Apogee Control Panel. If youre using Logic Pro, please see the description of the Apogee Control Panel in the Logic Pro documentation. Unit select - When multiple Apogee devices are connected to the computer, this selection designates which device is currently being controlled by Maestro. Identify Unit When checked, all LEDs on the active Ensembles front panel light, thereby allowing easy identification of the hardware receiving software control panel settings. Clock Source Select This drop down list is used to set Ensembles clock source to Internal or to the S/PDIF Coax, Optical, or Word Clock rear panel inputs.
SRC Select Sample rate conversion is applied to the stereo audio path selected in this drop down list. When converting a digital input (at any sample rate) to the sample rate of Ensemble (and thus the DAW session), apply sample rate conversion to the digital input. SRC Rate When converting the output of the DAW session to another sample rate, apply sample rate conversion to a digital output (under SRC Select) and select the desired destination sample rate in the SRC Rate drop down list. UV22HR UV22HR is applied to the stereo audio path selected in this drop down list. UV22HR should be applied to analog and digital inputs when recording to a 16bit session and applied to digital outputs when routing signals from Ensemble to 16bit digital devices such as external CD burners or DAT recorders. UV22HR is only available at sample rates of 44.1k 48k, as higher sample rate formats and devices support 24 bit operation only. I/O Allocation With this drop down menu its possible to allocate the number of channels made available through Firewire I/O. When using slower host computers and/or higher sample rates, allocating fewer channels to Firewire I/O means less CPU resources are used for Firewire communication. Please note that when an 18 x 18 allocation is selected, the highest sample rate possible is 96kHz. Also, any hardware I/O may be routed through the available Firewire I/O in the Maestro Routing pages. Bandwidth used This meter measures the percentage of bandwidth used by all Firewire AUDIO devices connected to the Macs internal firewire bus. Bandwidth used by hard drives is not included. If the meter reads 100%, select a smaller I/O Allocation setting. Optical In This drop down list sets the digital format of the rear panel Optical In to either S/PDIF or ADAT/SMUX. Optical Out This drop down list sets the digital format of the rear panel Optical Out to either S/PDIF or ADAT/SMUX. Meter Display The signal displayed by the front panel meters may be set from this drop down list. Settings available are Off (meters display no signal), Input (meters display Ensemble inputs) or Output (meters display Ensemble outputs) Word Clock Out The rate of the word clock output may be set in this drop down list to be equal to the unit sample rate (WC x 1) or 1/2 the unit sample rate (WC x 1/2), to accomodate connected devices. CD Mode Checking this box sends a 44k1, 16bit stereo signal to the S/PDIF Coax output, regardless of the DAW session sample rate or bit depth. CD Mode sets UV22HR to S/DPIF Out, and if the DAW session is at any other sample rate than 44k1 sets SRC Select to S/PDIF Out and SRC Rate to 44k1. Hold Overs By checking this box, the red Over indicators on the front panel meters and in Maestros Settings/Output page remain lit until the Clear Meters button (in Maestros Mixer window) is clicked. Input Settings : Soft Limit When checked, Apogees Soft Limit overload protection is engaged on the corresponding Analog input. Input Settings : +4, 10, MIC The nominal reference level of each analog input is selected with these radio buttons. Inputs 14 may also be set to MIC level, allowing gain to be set from +10 to +75 dB. Output Settings The nominal reference level of each analog output is selected with these radio buttons.

Maestro Control: Settings - Settings (diagram)
Maestro Control: Levels - Output
Level Control Three knobs provide level control for the Main, HP1 and HP2 outputs. Output attenuation from 0 to 127 dB is displayed in a corresponding readout. Meter Display Signal present on any channel selected in the MAIN Format Select or HP 12 Source Select drop down lists is displayed on the corresponding meter. MAIN Format Select This drop down list is used to configure the analog outputs for various monitoring situations. When Format is set to None, all Analog outputs function as standard Line outputs; the Main Level fader has no function. When Format is set to Stereo, the Main Level fader (and front panel Output encoder) controls the level of Analog outputs 12. Outputs 38 function as standard Line outputs. When Format is set to 5.1 Surround, the Main Level fader (and front panel Output encoder) controls the level of Analog outputs 16. Outputs 78 function as standard Line outputs. When Format is set to 7.1 Surround, the Main Level fader (and front panel Output encoder) controls the level of all the Analog outputs.
HP1 HP2 Source Select These drop down lists are used to select the stereo signal source for the front panel headphone outputs.
Maestro Control: Levels - Input
Pre1 Pre4 The following controls are provided for Pre1Pre4
Gain Control This knob provides gain control for the mic pre. Mic pre gain from +10 to +75 dB is displayed in a corresponding readout. Meter Display This meter displays the conversion level of the corresponding channel, for a convenient reference when setting mic pre gain. Groups The Gain Control of two or more Pres may be linked by selecting the same Group in this drop down list. The Gain offset present when Pres are initially grouped is maintained after grouping.

Troubleshooting

The power switchs blue LED is lit, but no other LEDs are on; is the unit in operation? Not yet; when Ensemble is connected to AC power, the power switch illuminates dimly to indicate that the unit is in Standby. Press the power switch to power up Ensemble. How can I quickly verify if the Ensemble system is operating correctly? Verify that Ensembles STATUS LED is solid blue (verifies Ensemble hardware clocks); Check that the unit appears in AMS by serial number (verifies Firewire audio connection); open Maestro (or Logic Pro Apogee Control Panel), click on Identify Unit and verify that all LEDs light (verifies Firewire software control connection). Ensemble doesnt show up in my audio program or in Audio Midi Setup. Verify that the required version of OS X is installed Is Ensembles STATUS LED solid blue? If not, reconnect the Firewire cable or replace the cable. I cant control Ensemble from Maestro or Logic Pro Apogee Control Panel. Verify the presence of this file : System > Library >Extensions > apogfwplugin.bundle. If you dont find it, reinstall software from the CD included with Ensemble. Theres no signal on Analog output 12. Open Maestro, set Meter Display to Output, and verify that a signal is displayed on the meters. If no signal, check routing from the software audio application. If signal is displayed on the meters but not present at Analog outputs 12, check that the MAIN output level is up (either in Maestro or using the front panel OUTPUT encoder). The front panel OUTPUT encoder knob doesnt attenuate the signal on Analog output 12. When Format Select is set to None (in Maestro), the front panel OUTPUT encoder does not attenuate output level. Set Format Select to Stereo. The meters arent working at all. Verify the METER setting in the Apogee Control Panel in Logic, it might be set to OFF.

I want to run Ensemble at 176.kHz, but I only see 44.196 kHz in AMS. Ensemble can operate at sample rates of 44.1 to 96 kHz or 176.4 to 192 kHz, as determined by
the Sample Rate Range setting in the Apogee Maestro Settings panel. To change the sample rate range, open the Maestro>Window>Settings panel and set Sample Rate Range to the desired setting. When setting the range, quit all audio software apps and allow 30 seconds for Ensemble to reboot at the new sample rate range
Im trying to lock Ensemble to an external source, but the STATUS LED just wont stop blinking. When Ensemble is locked to an external source, Ensembles sample rate is still determined by
the selection in software. Thus, the sample rate of the external source must be manually set to match the software sample rate. For example, if you want to open a session at 88.2 kHz but lock Ensemble to word clock from an Apogee Big Ben, you must manually set the Big Ben to 88.2 kHz.
How do I reset Ensemble to its default settings? Ensemble may be reset by pressing in the front panel left encoder and then powering on the unit;
continue to press the encoder until the unit has completed its boot-up sequence.

Web: http://www.apogeedigital.com/ APOGEE ELECTRONICS CORPORATION warrants this product to be free of defects in material and manufacture under normal use for a period of 12 months. The term of this warranty begins on the date of sale to the purchaser. Units returned for warranty repair to Apogee or an authorized Apogee warranty repair facility will be repaired or replaced at the manufacturers option, free of charge. ALL UNITS RETURNED TO APOGEE OR AN AUTHORIZED APOGEE REPAIR FACILITY MUST BE PREPAID, INSURED AND PROPERLY PACKAGED, PREFERABLY IN THEIR ORIGINAL BOX. Apogee reserves the right to change or improve design at any time without prior notification. Design changes are not implemented retroactively, and the incorporation of design changes into future units does not imply the availability of an upgrade to existing units. This warranty is void if Apogee determines, in its sole business judgment, the defect to be the result of abuse, neglect, alteration or attempted repair by unauthorized personnel. The warranties set forth above are in lieu of all other warranties, expressed or implied, and Apogee specifically disclaims any and all implied warranty of merchantability or of fitness for a particular purpose. The buyer acknowledges and agrees that in no event shall the company be held liable for any special, indirect, incidental or consequential damages, or for injury, loss or damage sustained by any person or property, that may result from this product failing to operate correctly at any time. USA: Some states do not allow for the exclusion or limitation of implied warranties or liability for incidental or consequential damage, so the above exclusion may not apply to you. This warranty gives you specific legal rights, and you may have other rights which vary from state to state. Service Information The Ensemble contains no userserviceable components: refer to qualified service personnel for repair or upgrade. Your warranty will be voided if you tamper with the internal components. If you have any questions with regard to the above, please contact Apogee. In the event your Ensemble needs to be upgraded or repaired, it is necessary to contact Apogee prior to shipping, and a Return Materials Authorization (RMA) number will be assigned. This number will serve as a reference for you and helps facilitate and expedite the return process. Apogee requires that shipments be prepaid and insured unless otherwise authorized in advance. IMPORTANT: ANY SHIPMENT THAT IS NOT PREPAID OR IS SENT WITHOUT AN RMA NUMBER WILL NOT BE ACCEPTED.
