“Avocet” is designed to solve the problems of accurate monitoring and volume control as required by workstation users, studios and mastering rooms alike. Avocet is a stereo controller with three digital inputs, three analog inputs and a headphone system. All digital signals are up-sampled and jitter reduced to ensure highest accuracy during D/A conversion. Options are available to change the D/A mode, all though the default mode has been chosen as more accurate.
Avocet’s many features including; dim, mute, phase, mono, and 16 bit truncation functions, plus a speaker select switch that sends line level balanced audio to one of three outputs. The six input sources have on the fly gain trim capability.
An accessory connector has extra functions for the technically minded. They are; buffered stereo output, mono output, talk back mic output, headphone bus output, and several input control functions such as; talk back enable, mute and input selection control that could be used for a pre-listen or solo command. This connector is also used to tie audio boxes together for surround operation.
The Quantum DAC is the 5th generation design from Crane Song and has less then 1pS jitter.
The Quantum DAC uses 32 bit a converter and ASRC for jitter reduction up sampling to 211KHz. Avocet has always upsampled to 211KHz. The reference clock has less then 1pS, 0.5pS typical 1Hz to 100KHz and a proprietary reconstruction filter for accurate time domain response.
New Direct sub woofer outputs
... for each of the three output have been added.
The output levels are now programmable in 0.25 db steps for speaker level matching.
The internal headphone amplifier can be fed from the program source or an external input. Provisions for a talk back function are included.
The three headphone sources are
- The analog AUX input
- Main, meaning the audio source selected by the input button
- Program, meaning the audio source selected by the input button.
However the level control, mono and phase buttons also apply to the program source.
All three phone sources have individual gain settings controlled by the green knob.
The talkback mic (not supplied and there is no phantom power) is hooked into the xlr connector on the remote. The talk back mic signal is mixed into the headphone amplifier along with the selected headphone source. By sending a cue mix to the Aux input you can use the headphone system for doing overdubs in the studio and have communication to the artist. At the same time the main audio path can operate independently of the headphone system.
By using 3 two channel audio boxes Avocet will function as a 5.1 system, and 4 audio boxes makes a 7.1 system. See the speaker setup information. This function allows
intergrating, both surround and stereo speaker systems. A metering system is under discussion. A specially made accessory cable connects the audio boxes when working
Systems that ship surround from the factory have lables on them as to how the audio boxes are configured.
