From mic preamps to Mac CoreAudio connectivity to headphone outputs, Ensemble includes all that's necessary for a high­quality Mac­based recording system. Ensemble includes several of Apogee's 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 Apogee's 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) Ensemble's hardware sample rate conversion provides a high quality, flexible solution for working with digital audio hardware and software running at different sample rates. Ensemble's sample rate conversion may be applied to a digital input (to convert an input stream to Ensemble's sample rate) or to a digital output (to provide an output stream at a user selected sample rate different than Ensemble's rate). Ensemble Requirements 1. Apple PowerMac 1.5GHz or higher, 512MB of RAM required, 1GB recommended 2. OS X 10.4.6 3. Apple Logic Pro 7.2.1 4. One Firewire 400 cable (per Ensemble) 3 Ensemble ­ User's Guide APOGEE ELECTRONICS Getting Started Quickly 1. Installing software VERY IMPORTANT! BEFORE CONNECTING ENSEMBLE... Insert the CD that is attached to this document into your Mac and double click on the "Apogee Software Installer". Follow the on screen instructions to install the necessary software (figure 1). figure 1 2. Hardware connections Using the enclosed FireWire cable, connect one of Ensemble's FireWire ports to a FireWire 400 port on your Mac (figure 2). figure 2 Connect Ensemble's AC input to an AC outlet of 90 to 250 volts; Ensemble's power switch will illuminate to indicate the presence of AC. Press the power switch to turn the unit on (figure 3). figure 3 Connect a pair of headphones to Ensemble's 1 output (figure 4). figure 4 4 Ensemble ­ User's Guide APOGEE ELECTRONICS Getting Started Quickly 3. OS X configuration From your Mac's Apple menu bar, open the System Preferences window, then click on the sound icon (figure 5). figure 5 In the Sound Preferences window click on the Output tab and select Ensemble (figure 6). figure 6 4. iTunes playback Open iTunes, select an audio file and initiate playback (figure 7). figure 7 Press the OUTPUT encoder knob until the LED is lit and adjust the level in your headphones (figure 8). 1 figure 8 5 Ensemble ­ User's Guide APOGEE ELECTRONICS Getting Started Quickly 5. DAW configuration Configure your CoreAudio compatible software to communicate with Ensemble hardware I/O. For example, in Logic Pro: Open Audio > Audio Hardware and Drivers > Drivers > CoreAudio and check the Enabled box (figure 9). Click "OK" when prompted by Logic. figure 9 Select Ensemble in the Driver field (figure 10), and click Try (Re)­Launch when prompted by Logic. figure 10 To "customize" the I/O routing labels in Logic to match Ensemble hardware I/O, open Audio > Audio Configuration; under the View menu, select I/O Labels; under the Drivers' I/O Label column, Option­click the first radio button of each group of I/O labels (figure 11). figure 11 To control Ensemble directly from your Logic session, open Audio > Apogee Control Panel (figure 12). If you're using another CoreAudio compatible audio software app, use Apogee's Maestro software (installed in your Applications folder in Step 1) to control Ensemble. figure 12 6 Ensemble ­ User's Guide APOGEE ELECTRONICS Getting Started Quickly 6. Recording Connect a mic to the MIC 1 rear panel connnection (figure 13). figure 13 or an instrument to the HI­Z 1 front panel connection (figure 14). figure 14 In Logic, set a track's input to Analog 1 and its output to Analog 1/2 and record enable the track (figure 15). figure 15 Press the front panel INPUT encoder knob until the Pre 1 LED is lit, and turn encoder to obtain a proper recording level on the record­enabled track (figure 16). You're now ready to record! figure 16 7 Ensemble ­ User's Guide APOGEE ELECTRONICS General Operation Making Settings with Software Control Panels All Ensemble settings are made from Apogee's Maestro Settings panel or Logic Pro's Apogee Control Panel. Certain settings can be also be made from OS X audio control panels. It's 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 Ensemble's front panel encoders, as described on the lower half of this page. 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 Maestro's 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 Ensemble's clock source, sample rate and output level. To set Ensemble's output level using the Mac's 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 Ensemble's front panel. For example, if the front panel 1 LED is lit, OSX audio faders control the 1 output level. Making Settings with Ensemble's Front Panel Encoder Knobs Ensemble's 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 8 Ensemble ­ User's Guide APOGEE ELECTRONICS General Operation Setting Sample Rate To set Ensemble's 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 OS ...
