Chapter 1: Introduction to the MADI 700 Series
This guide describes the following MADI 700-series converters
for System5:
• AM713 Analog to MADI Converter
• MA703 MADI to Analog Converter
• DM714 Digital to MADI Converter
• MD704 MADI to Digital Converter
AM713/MA703
The AM713 and MA703 converters provide MADI conversion
to/from analog equipment such as consoles, tape decks, mi-
crophone preamplifiers and other analog devices. Both con-
verters 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 in-
puts, there are two auxiliary analog inputs (XLR) and two aux-
iliary digital inputs (S/PDIF or AES/EBU); only one digital con-
nector 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.
DM714/MD704
The DM714 and MD704 converters provide MADI conversion
to/from digital (AES/EBU) equipment such as digital
multi-track recorders, digital audio workstations, audio rout-
ers, 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 auxil-
iary digital connector can be used at a time. Each main
AES/EBU input is automatically evaluated for sample-rate con-
version. The incoming sample rate is compared with the inter-
nal 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 con-
version reduces a 24-bit signal to 20 bits.
The MD704 converts incoming MADI signals to 24 digital out-
put channels (12 AES/EBU pairs). 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). The main
24 outputs can be bit-depth converted from 24 to 20 or 16
bits.
