Speaker Connection - Speco PBM-15 Instruction Manual

Warning
To overcome this potential problem, the electrical and the mechanical ground on the amplifier
may be separated by completely removing the wire connecting the power source to ground.
CONSULT AN ELECTRONICS TECHNICIAN TO ACCOMPLISH THIS TO AVOID POTENTIAL
PERSONAL INJURY OR A HAZARDOUS CONDITION.

SPEAKER CONNECTION

The rear panel of the amplifier contains a 7 screw terminal strip for connection of speakers.
BE CAREFUL TO CONNECT SPEAKERS PROPERLY, see impedance and line voltage instructions
below.
The speaker lines are connected directly between the appropriate COM terminal on the 7 screw
terminal strip and the terminal corresponding to the impedance of the speaker(s) or of the line voltage
selected.
4, 8 and 16 OHM CONNECTIONS (refer to figure 3).
Connect the cables to the terminals on the 7 screw terminal strip provided. Use the screw terminals
which correspond to the impedance of the speaker(s). One lead must always be connected to the
COM. This is just an example. If in doubt consult a qualified technician.
