I have two of these - in excellent working condition. They are being used at a lab at UNSW. We can demo them if you like.

The MA703 converts incoming MADI signals to 24 analog channels. In addition to the 24 analog outputs, there are also two auxiliary analog outputs (XLR) and one auxiliary digital output pair (S/PDIF or AES/EBU).

Professional audio conversion is accomplished utilizing 128 times over-sampled noise-shaped delta-sigma techniques. The analog to digital conversion employs a multi-bit modular architecture while the digital to analog conversion employs a single-bit modulator architecture. Low-jitter reference clocks are provided utilizing digital PLL techniques with VCXO and VCO oscillators.

The analog inputs and outputs can be calibrated from the front panel of each unit. Four segment LEDs on the front panel monitor signal level. LED meter segments indicate -42, -18, -6 (green) and -0.005 dBFS (red).

AES/EBU and Word Clock external sync inputs provide synchronization to digital systems. Sample Rate Source and Sample Rate are automatically sensed by both units. Supported sample rates include 44.1, 48, 88.2, and 96 kHz. In addition, pull-up and pull-down rates for the standard sample rates, as well as custom sample rates are available.
