Connection and setup Connect the rear IEC inlet (14) to the mains using the supplied mains lead (or an equivalent approved type). Ensure that the voltage is correct as indicated on the voltage selector (13) and that the mains outlet is switched on. Alternatively, the amplifier can be powered by a 24V battery, such as a lorry or boat battery, by connecting the “+” and “-” of the battery to the 24Vdc INPUT (15) on the rear panel. Ensure that DC cables are capable of handling the current (10A min.
Speaker outputs The RM series amplifiers can be used either as 100V line amplifiers or standard low impedance power amplifiers. These 2 configurations cannot be used together, so it is important to decide which method will be used at the start. 100V line systems 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.
Operation When all connections to the amplifier are made, turn all rotary controls down and switch on the power (11) and a power “ON” LED will illuminate. Turn BASS and TREBLE controls to the 12 o’clock position (pointing straight up) and turn the MASTER rotary control (5) up part way for testing. Ensure a signal is being fed to one of the line inputs 2, 3, 4 or 5 and gradually increase the volume control for that channel until the output is heard through the speakers.
