The DUAL TBP TECHNICIAN intercom is an supplementary apparatus that allows to amplify the functionality of ENGINEERING intercom fitting between it and the users (cameras or other devices connected to channels lines).
The microphonic signal of TBP TECHNICIAN is added to the signal coming from the microphone of ENGINEERING intercom going to cameras or to users connected to channels lines.
The signal coming from cameras or users connected to channels lines is listened in loudspeaker by both intercoms.
To be able to connect the two intercoms are necessary pin-to-pin cables with 9 pin DB connectors.
The DUAL TBP TECHNICIAN is equipped with two microphonic inputs that can be selected through HEADSET stable button.
The HEADSET connector is 4 contact cannon and provides the necessary power supply for powered microphones.
On the same connector there is also the signal to be able to power a low or high impedance headset.
When this microphonic input starts up the loudspeaker disconnects.
The MIC connector is 3 contact cannon and provides the necessary power supply for powered microphones.
