Audio Outputs
The 620X VHF Transceiver includes four fully configurable outputs:
• Headphone 1 output, rated output power is 300 mW into 75 Ohm.
• Headphone 2 output, rated output power is 200 mW into 75 Ohm.
• Speaker output, rated output power is 4 W into 4 Ohm.
• LINE-OUT output intended for ground station use only
Note: Headphone 2 and speaker output cannot be active at the same time
Mike Inputs
The VHF transceiver has an input for dynamic microphone (DYN_MIKE) and
an input for standard microphone (STD_MIKE).
The 620X VHF Transceiver provides four microphone inputs:
• standard microphone input 1 (STD_MIKE1)
• standard microphone input 2 (STD_MIKE2)
• standard microphone input 3 (STD_MIKE3)
• dynamic microphone input (DYN_MIKE)
Each input is able to operate with one single microphone or with two
microphones of the same type connected in parallel.
AF Auxiliary Input
The AF auxiliary provides the interface to connect an external audio
source (e.g. NAV, music-player) to the transceiver. Interconnection of
multiple external audio sources on this particular port requires
