MIC 1 channel has an option for +20V phantom power for condenser microphones
and paging microphones with chimes.
MIC 1 also has the option of VOX control, which attenuates the line input channels 4
and 5 by -40dB when MIC 1 signal is detected and returns them to normal when
MIC 1 signal is silent.
MIC/LINE 2 (23) and MIC/LINE 3 (22) inputs can be set to MIC (up position) or LINE (down position)
sensitivity to suit the type of input being used. Be sure to make these DIP switch settings when the
amplifier is switched off. Making any changes when the amplifier is powered up may cause loud
transient noises which can damage the speakers.
