2 or 4 20Hz-15KHz CD quality audio channels.
Offers to traditional analog radio links a CD audio quality.
Correct decoding with an SNR of the digital signal as low as 30dB.
PAM type coding of channels, with 2 levels, a partial response, which enables to reduce the bandwidth.
Minimum channel width required: 250KHz (2ch.) or 450KHz (4 ch.).
Auxiliary Data Channel RS232.
Automatic muting in case of synchronization loss.
Led bar indicating the audio level.
Meets or exceeds all FCC requirements.
Modular composition which enables an easy replacement of circuits and parts.
Two indipendent outputs of the digital signal coded by the DTX.
Output of the regenerated digital signal on the DRX which allows multiple leaps without any additional costs.
Easy to upgrade from 2 to 4 channels.
