ATR833 / P/N 833-(1xx)-(1xx)  

Operation and Installation 

 

3.6 Equipment Connections 

One 25 pin D-SUB miniature connector includes all electrical 
connections, except for the antenna 

 

The (+UB)-wire has to protected by circuit breaker (4 Amp. 
slow-blow)!

The inputs for standard microphones are appropriate for input voltages of 
50 mVpp to 2 Vpp. These inputs have a bias voltage of 8 V at 330 ohms. 
Sensitivity is adjustable in the init menu with MIC. (see 2.8.4). 
The inputs for dynamic microphones are appropriate for input voltages of 
5 mVpp to 10 mVpp. These inputs have no bias. 
In general standard and dynamic microphones (headsets) can be used 
simultaneously. 
In motor gliders, when the engine is running, the dynamic microphones 
should be turned off (switch Ld/Rd inputs to GND), in order to avoid the 
transmission of the engine’s noise. 
If no dynamic microphone is installed, the input sensitivity MIC for Ld/Rd 
shall be set to 1 (MIC01…see 2.8.4 MIC – Settings page 22). Therewith 
these microphone inputs are set to “insensitive“. 
Per microphone input two microphones may be connected in parallel. 

3.6.2 Headset-Connection 

Headphones may be connected parallel as long as the total impedance 
doesn’t fall below 8 Ohm.
