Product Code: 26-907 The SSA324 dual system convertor will convert any 2 wire beltpack system to a n individual audio output and audio input.
It comprises of 2 system interfaces which can be used individualy to obtain Audio in and Audio out from an RTS loop or in tandem to convert a Tecpro system to an RTS system for instance. (Call light transfer requires and additional internal card in the box). The additional card in the SSA324 also allows simplex walkie talkie interface operation.
SPECIFICATIONS: | 2 wire operating levels: | -20 dBu to +0 dBu | | 4W in to 2W: | 200 Hz to 5 kHz | | 4W out to 2W: | 250 Hz to 5 kHz | | Operating levels 4 W in: | -10 dBu to +8 dBu | | 4W out: | -10 dBu to +8 dBu | | Weight: | 2.3kg + 0.45kg for rack kit |
 Each of the SSA324's 2 convertors provides an Audio Output (from RTS) and an audio Input (To RTS) on the 15 pin D connector or the tag blocks on the rear of the SSA324 seen in the image adjacent.
The front panel null adjustments (Hi Med Lo) each control different parts of the separation of the output and input audio.
A good null will deliver the best separation. The Bruce Cocks' dummies guide to near perfect nulling of the SSA324 is attached
The Digital SSA424 will deliver automatic nulling but won't let you do talk through on radios comms as it will always seek a perfect null.
Radio talk through is slightly off the perfect null by a tweakers's blade width! This will let just enough of the output audio back onto the input for talk through to be achieved between radios!
