Four high impedance balanced analog inputs are provided on a high density 15-pin D connector. Two AES outputs (four copies of each) are provided on BNC connectors. The module has a built-in 48 kHz crystal-controlled sample rate clock, or it may be locked to an external AES3id reference. An LED is provided on the front of the module to indicate the presence of a valid external reference.
Four additional LEDs illuminate when the analog input signals reach reference digital output level. A dip switch allows reference digital output level to be set to -16, -18, or -20 dBFS. A rotary control is provided to set the gain of the analog input stages. All local controls and status indicators are available via the Avenue remote control system.
