4 CONNECTIONS

Power is supplied to the unit via an IEC connector with integral fuse

holder/voltage selector. To change to a different mains voltage remove the

rectangular fuse cap, rotate and replace so that the correct voltage is

indicated by the arrow on the body of the receptacle.

The earth terminal on the IEC connector is permanently connected to the

chassis.

The electronic reference 0V is taken to chassis via the rear panel signal

ground switch. This inserts a ground lift resistor when switched to off.

The inputs and outputs of the MX5 are electronically balanced, pin 2 being

designated + (hot). Because both inputs and outputs are balanced either

pin can be assigned as + (hot) provided the convention is maintained

through the controller.

4.1 Input Connections

The MX5 inputs are on female XLR type connectors and are electronically

balanced. Pin 1 is normally open circuit but may be linked to sig 0V or

chassis earth by inserting a hard wire link on the PCB (see Fig 1). The

signal is always applied between Pin 2 (hot +) and Pin 3 (cold -).
