The ATR833-II replaces the well-known ATR radio with the new channel separation of 8.33kHz.
Transmitter and receiver are a complete new development with state-of-the-art digital signal processing.
The built-in voice controlled intercom operates up to 4 microphones (2 standard, 2 dynamic).
In many cases no extra intercom is required, this saves cost and weight.
All microphones are adjustable separately. Using suitable headsets a 4-place intercom can be built-up.
The ATR833-II has 2 memory functions: Up to 100 frequencies can be stored together with an identifier. Moreover, the 10 last used frequencies can be recalled easily.
The OLED display ensures a high contrast and is suitable for installations without direct sunlight.
For the radio, a large number of cable adapters are available, so that in most cases an easy replacement of the device is possible.

Delivery is including the EASA Form-I document, and including connector (SSATR2).
The ATR833-II can be remotely controlled using the ATR833RT remote control unit.
