Model DSA-101
Remote Speaker Amplifier
General Information
This data sheet applies to the Model DSA-101 Remote Speaker Amplifier, which is designed specifically
to enable audio received by a DHX Series Intercom Station to be broadcast into high noise areas. It is
part of the GAI-Tronics Digital Intercom system which is designed for use in hazardous and nonhazardous area communications, both indoors and outdoors
The speaker amplifier requires a 24 V ac or dc power source to operate. A DHX Intercom Station with an
audio line output is required as the audio source. Audio received by the DHX Intercom Station is
automatically transmitted to the remote speaker amplifier, except when the intercom station’s handset is
off-hook. A maximum of six remote speaker amplifiers can be connected to a single Intercom Station.
The Model DSA-101 Remote Speaker Amplifier consists of a rear enclosure and a front panel assembly.
The front panel assembly contains power and fault status indicators. Controls for speaker volume and
gain are provided on the 69829-00x speaker amplifier PCBA, which is housed in the rear enclosure. All
field terminations (audio in/out, power, and speaker) are to be made in the rear enclosure.
