Audio Modules

Models: ADA424, DAA424, DIA224, DOA224, ADAVIO


The ADA424 has 4 input channels that convert analog audio to digital data @ 48kHz with 24-bit audio depth. The module accepts line level signals and each input may be assigned to any number of DAA424 output(s) on the network using the PathMaster 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 4 input channels and the DOA224 is the AES3/EBU version with 4 output channels.

ADAVIO Module Features


The ADAVIO 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 input/output where audio intelligibility is a requirement. Each channel can be set to a bussed Audio "Net" with IMT's PathMaster application enabling system wide audio intercom and FSK data applications. Signal level LED's indicate both transmit and receive audio levels.
