Features
▪ TheaudiosignaloftheMediaplayeristransmittedtotheAudioamplifier(forwardaudio).
▪ The microphone signal is routed back to the Audio recorder device (return audio).
ATTENTION!
The return audio (from the Decoder to the Encoder) is available only if the analog audio input
is selected in the Encoder to transmit towards the Decoder. Thus, the other analog audio signal (MIC IN)
connected to the Decoder can be routed back to the Audio output of the Encoder.

ATTENTION! Themicrophoneinputportappliesafixedbiastofeedtheconnectedelectret(condenser)
