Analog - MADI Converter
26 channels of high quality, analog/digital conversion up to 96KHz 24-bit in each rack unit.

The AM713 and MA703 24-bit converters provide MADI conversion to and from analog equipment such as consoles, tape decks, microphone preamplifiers and other analog devices. Both converters are two rack spaces high and are housed in a stainless steel chassis with machined, heavy aluminum front panels.

The AM713 converts incoming analog signals to 24-bit MADI digital signals that capture the input's complete dynamic range. In addition to the 24 XLR connectors for the analog inputs, there are two auxiliary analog inputs (XLR) and one auxiliary digital input pair (S/PDIF or AES/EBU).

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 on both units 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.
