48V power supply, phase and high pass channel and a line selector and three LEDs indicating the level between the floor of the channel.
I find it good, sound rich enough, a report siganl / noise rarely achieved this award
against by the level conversion APRS output is often as super low, forcing the board in between station console or a digital trim.
8 channels P48V, Phase, High-pass
Conversion ADDA 24/192
MS decoder adapters
Line IN sym
Line OUT sym
it is inconvenu want to compare it with a mono amp pr 5000 euros, 1000 euros but for the 8-channel converters 24/192 integr trs is well !!!!!!
