Audio Modules


The ADA424 has 4 input channels that convert analog audio to digital data with user selectable 16, 20 or 24-bit audio depth. The module accepts line level signals and each input may be assigned to any output(s) on the network using the IMT software application for "any to any" routing.


The DAA424 has 4 output channels for analog line level audio. Each of the outputs can select any source channel present on the network.

The DIA224 is the AES3/EBU version with 2 stereo inputs and the DOA224 is the AES3/EBU version with 2 stereo outputs.

ADAVIO Module Features

The ADA-VIO is a 4 channel, two wire bidirectional audio interface module intended for use as an Intercom or for FSK (Frequency Shift Keying) applications.

Transformer I/O coupling and audio Tx/Rx processing allows for both transmit and receive on the same copper I/O pair.

24 bit @ 48kHz processing provides high quality signal inputs and outputs where audio intelligibility is a requirement.

Each channel can be set to a bussed Audio "Net" with IMT's ExNMP (Extended Network Management Protocol) so system wide audio intercom and FSK data applications are easily implemented.

Signal level LED's indicate both transmit and receive audio levels.

Max Input 3.8 dBu @ 50 ohms
Dynamic Range 93dB typical
Frequency Response 200Hz-20kHz
Sample rate 48kHz Fixed
Oversampling 64X
Group propagation delay 1.23ms
Signal indicators Green = -22 dB
Amber = -16 dB
Red = Clip
Audio connectors Dismountable mini Phoenix
