P-2000/P-3200 Power Amplifier
Speaker Connection Procedures
Always switch the power off before connecting speakers.
After removing approximately 10mm (1/4 inch) of insulation from the ends of the speaker
cables, twist the strands tightly and pass the bare ends through the holes in the terminals,
tightening the terminals to secure the wires.
Make certain the wires do not protrude from the terminals and touch the amplifier’s
chassis, or an adjacent terminal.
The P-2000/3200 is capable of very high output levels. Be certain to use a speaker system
that can accept high input levels. If the input capacity of your speaker system is less than
the amplifier’s rated output, you may protect your speakers by connecting a fuse
between amplifier and speaker, as shown below:
Use the following formula to determine the needed fuse rating:
P0 (W) = Speaker’s input capacity (RMS)
R () = Speaker’s nominal impedance
I = Required fuse rating.
For example: if the speaker’s input capacity is 100W, with 8 impedance,
The required fuse rating is 3.5A.
