DB25 Audio Connections
Aviom analog input and output modules with DB25 multi-pin
connectors are wired to the analog pinout that has become standard
in the audio industry (which is sometimes referred to as the Tascam®
DA-88 or DTRS pinout). This wiring standard allows easy interfacing
with a variety of audio equipment using readily-available multi-pin
breakout cables or by incorporating Aviom’s PB28 Modular Patch Bay
products. Each DB25 jack on an Aviom product carries eight balanced
audio channels.
Note that digital devices that transmit AES3 digital audio data
(sometimes referred to as AES/EBU) use a different wiring pinout;
analog and digital multi-pin breakout cables and/or patch bays are not
interchangeable.
