Pro Intercom AD913 Simplex Transceiver Adapter

The AD913 permits communications between a cabled intercom system and any number of standard, simplex, (press-to-talk) transceivers. One of your transceivers is dedicated as base, and connected via its accessory mic/spkr jacks to the AD913. Transmissions from other transceivers (on the same frequency) are then heard at all intercom stations on the same circuit as the AD913. Stations may then transmit to the remote transceivers by simply pressing and holding their signal light button.

The AD913 is connected to the intercom system as is a belt-pack, via the female 3-pin XLR on the rear. The AD913 is powered by the intercom power supply. Connection to the (base) transceiver is made through a 6-pin male XLR, also on the back panel. Pro Intercom can provide connecting cables for most popular makes of transceivers. The cable is NOT included with the AD913 as each is custom and must be ordered as a separate item. The front panel contains two 15-turn potentiometers for matching the send and receive levels of the transceiver to the intercom system.The input stage of the AD913 includes a studio quality microphone transformer. The output is also transformer isolated. Frequency response has been carefully shaped to optimize both intelligibility and long-term listening comfort.
