The ATR833A-II replaces the well-known ATR833A radio with the new channel separation of 8.33 kHz.
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 ATR833A-II has 2 memory functions: Up to 20 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.
The ATR833A-II can be remotely controlled using the ATR833RT remote control unit.
