Connection Diagrams
Unbalanced Connections
If your preamplifier has RCA outputs, it can be connected to the amplifier inputs as shown. The
amplifier will boost the preamplifier’s output, up to a level suitable for driving speakers.
Make sure that the positive speaker wires do not touch the negative speaker wires, or any chassis
metal. This will cause a short circuit and may activate the protection circuitry. The 12 VDC trigger
connection shown can be used to turn the amplifier on when the preamplifier turns on. This is the
preferred method of activating the MPS-1. Alternatively, you could use the amplifier’s SIGNAL switch
position. The amplifier will then automatically turn on when a preamp audio signal is received.
