Wiring Information

Outputs For PM-3180 Amplifier

Each amplifier channel has its own output terminal strip on the rear panel. Each terminal strip can handle a different type of speaker load. All amps can handle 70V & 25V distrib-

uted or 8-Ωor 4-Ωloads. The

70V, 25V and 8-Ωoutputs are transformer-coupled. The 4-Ωoutput is directly connected to

the amplifier output. The 4-Ωoutput provides a wider fre- quency response with better bass reproduction and lower distortion.

To connect an 8-Ω, 25V or 70 load, attach one lead to the COM terminal and the other to the terminal corresponding to the output desired. Ensure that the shorting clip connects COM and GND and that the shorting clip for the LINK is installed.

The transformer-coupled out- puts (70V, 25V, 8-Ω) can be made to float by disconnecting the shorting clip between GND and COM. This may be desir- able in certain situations where a balanced output is needed. In general, it is best to keep the shorting clip installed between GND and COM.

To connect a 4-Ωload, first remove the shorting clip between the two screw termi- nals marked LINK. Connect one lead of the 4-Ωload to the 4-Ωterminal and the other lead to the GND terminal.
