Egret is a highly flexible workstation back end.  It contains 8 channels of high quality D/A converters
and a stereo line level mixer with color options to help bring analog summed digital mixes to life.

The stereo mixer has a level control, a aux send which is post level control, a color control, and a pan
control  on each channel.  Each channel also contains an analog / digital source button, and solo -
mute buttons.

The color function is adjustable from a transparent sound to a complex mix of second and third
harmonic content.  Creating the possibility of having clean modern sounds mixed with vintage
sounds.

By using the balanced direct outputs and the balanced analog inputs you can insert analog
processing into individual channels.

The built in Aux bus with its master level control can be used as an effects send.  A balanced stereo
effects return is built into the system.

The master stereo bus level control, which is a stepped attenuator, has 1 db steps for most of its
range,  This allows for accurate gain control, repeatability, and stereo gain matching to better than .05
db.

The headphone system allows a monitor mix to be created when Egret is being used in multi channel
location recording.  Thus allowing the monitoring of all channels.

The D/A converters support sample rates up to 192K and have sample rate converters on each
channel for jitter reduction.  There is a front panel switch to disable the SRC for cases where lower
latency is required.   The system is built so that the converters and the interface can be upgraded as
the technology changes.

The standard interface supports AES single wire to 192KHz,  ADAT, and S/MUX to 96K.  The convert-
ers can also be independently operated, even at different sample rates.

Egret is built so that the stereo, and cue buses can be chained together to create a many input sys-
tem.  With a special cable Egret’s stereo bus can also be tied to a Crane Song SPIDER as a way to
sum additional analog inputs while working in a mix mode.
