100V SYSTEM
For 100V line systems, connect the amplifier to the first speaker in the system using double-insulated speaker wire which has
adequate current rating to handle the total output of the amplifier.
Connect the "100V" output terminal to the positive (+) connection of the speaker and "COM" output to the negative (-)
connection of the speaker. Connect further speakers in parallel to the first speaker with all positive terminals and connected
together and all negative terminals connected together as shown below.
A 100V line speaker system can comprise of many speakers connected together. The determining factor for how many
speakers can be used on a single amplifier is the power rating. For most purposes, it is advised to connect as many speakers
as needed with a combined wattage of no more than 90% of the amplifier's output power rating.
The terminals of a 100V speaker are connected to a transformer and in some cases, this transformer may be "tapped" for
different power ratings. These tapings can be used to adjust the wattage (and output volume) of each speaker in the system to
help achieve the ideal total power of the system for the amplifier.
LOW IMPEDANCE SYSTEMS
Alternatively, each zone output of the PRM1202 can power a low impedance loudspeaker. There is an option on each zone for
an 8Ω speaker output to determine the minimum impedance.
It is essential to select the correct output terminal when opting for low impedance speakers.
For a 8Ω speaker, connect the positive (+) wire to the "8Ω" terminal and the negative (-) wire to "COM"
Note: Lower impedance may cause irreparable damage to the amplifier.
The connected loudspeaker(s) must also have sufficient power to accept the zone output.
REPLACING THE FUSE
If the fuse is defective, replace the fuse with a fuse of the same type and value. Before replacing the fuse, unplug mains lead.
Procedure:
Step 1: Open the fuse holder on the rear panel with a fitting screwdriver.
Step 2: Remove the old fuse from the fuse holder.
Step 3: Install the new fuse in the fuse holder.
Step 4: Replace the fuse holder in the housing.
