PA400 REAR PANEL

Rear Panel Features.

32. Mains switch - Mains on/off switch
33. Mains Input- Socket to accept the mains
power lead supplied. (note: please ensure
that correct wiring practices have been
observed before use).
34-35. Loudspeaker outputs - Jack sockets
for the connection of loudspeaker
systems. The power output is 400 Watts
into 2 Ohms. Under no circumstances
should a total loudspeaker load of less
than 2 Ohms be connected.
