AMU1-CHD+mk2
Selects AES 1-2 and 3-4 (in conjunction with the channel
switch) and SDI 1 & 2 Groups 1-4
Selects AES1,2,3 and 4 and pairs 1 (D1) and 2 (D2) from both the
SDV inputs. Analogue 1 and 2 are also selected in position Anl 1
and Anl 2.
Left Channel is fed to the left bargraph and Right Channel is fed to
the right bargraph.
Momentary phase reverse between A1 and A2 pairs. A non
latching push switch with Red/Green LED indicates phase. Push to
reverse.
Allows the audio level to be varied.
