Monitor (Input monitor)
Unlike a tape recorder, WavePRO interfaces are full duplex audio
devices which means that you can record and play on all channels
simultaneously. We have also included an input monitoring feature
that allows the audio signal that is being input to WavePRO to be
"echoed" to the corresponding channel number output.
Important note
When Monitoring is enabled (ON) you will hear both the signal that is
being input to the WavePRO interface for recording and the audio
playback signal from the WavePRO interface. As noted in the
diagram, when monitoring, each input channel is monitored to its
corresponding output channel.
