• Preset memory recall function is assigned to the contact input and output pins at the factory. To change this
function assignment to give channel ON/OFF or line input selection, refer to p. 69.
• The V pins of the control input terminals can be used for LED connections. To do this, connect the contact
COM pins to use out of the C1 – 4 pins of the control output (7) or the C5 – 8 pins of the control output (8) to
the C pins of the control input (5) or (6). (The diagram below is an example where the control output's C1 –
4 pins are connected to the control input's C pins.)

• Never connect the V pins of control inputs (5) and (6) to the V pins of VCA pins (1) – (4) as the sound
volume may be affected due to voltage drop caused by these connections.
