Chapter 1: Introduction
1.1 AM713/MA703
The AM713 and MA703 converters provide MADI conversion to interface to/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 two auxiliary digital inputs
(S/PDIF or AES/EBU); only one digital connector can be used at a time.
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 two auxiliary
digital outputs (S/PDIF or AES/EBU). Only one digital connector can be used at a time.
1.2 DM714/MD704
The DM714 and MD704 converters provide MADI conversion to interface to/from
digital (AES/EBU) equipment such as digital multi-track recorders, digital audio work-
stations, audio routers, and facility patching systems. Both converters are two rack
spaces high and are housed in a stainless steel chassis with machined, heavy aluminum
front panels.
The DM714 converts incoming AES/EBU digital audio to MADI. In addition to the 24
input channels (12 AES/EBU pairs), there are two auxiliary analog inputs (XLR) and
two auxiliary digital inputs (S/PDIF or AES/EBU); only one auxiliary digital connector
can be used at a time. Each main AES/EBU input is automatically evaluated for sample-
rate conversion. The incoming sample rate is compared with the internal rate. If they are
the same, no conversion occurs. If the rates differ, sample-rate conversion is activated
and persists until a new input is applied or the internal sample rate changes. The sample-
rate conversion range is 32–56 kHz. Sample-rate conversion reduces a 24-bit signal to
20 bits.
The MD704 converts incoming MADI signals to 24 digital output channels (12 AES/
EBU pairs). In addition to the 24 analog outputs, there are also two auxiliary analog out-
puts (XLR) and two auxiliary digital outputs (S/PDIF or AES/EBU). The main 24 out-
puts can be bit-depth converted from 24 to 20 or 16 bits.
