Quartet’s optical connections offer 8 additional ADAT/SMUX digital inputs at samples rates up to 96kHz. With an interface like Apogee’s Ensemble connected via optical, it’s possible to record up to 12 mics at a time.
To setup Quartet and Ensemble (or any ADAT/SMUX equipped 8 channel interface) for this application:
1. Connect optical Toslink cables between the interface’s ADAT/SMUX outputs and Quartet’s Optical inputs. At sample rates of 44.1-48kHz, all eight channels are transmitted over one Toslink cable – one cable between the interface and the Optical IN 1 is sufficient. At sample rates of 88.2-96kHz, channels 1-4 are transmitted over one cable (connected to Optical IN 1) and channels 5-8 are transmitted over a second cable (connected to Optical IN 2).
2. Connect a BNC cable between Quartet’s WC Out and the Ensemble’s word clock input.
3. Setup Ensemble in standalone mode:
The gain of each mic pre may be controlled from the front panel by pressing the left hand encoder to select a pre and turning the encoder to the desired setting. The analog and headphone outputs may be controlled with the right hand encoder in a similar fashion.
4. To check input levels for Quartet, open Maestro, click the Input tab and check the ADAT (SMUX) meters.
