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 correct voltage is indicated on the voltage selector (13) and 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 DC INPUT (15) on the rear panel. Ensure that DC cables are capable of

handling the required current (10A min. recommended)

The RM series amplifiers have a total of 5 input channels. MIC 1 input (25) is fed to a dedicated microphone

channel. Connect the main announcement microphone to this channel using a balanced XLR lead.

Connect microphones or mono line inputs to MIC/LINE 2 and MIC/LINE 3 inputs (23, 22) using good quality

6.3mm jack leads. Make sure the correct sensitivity is selected for the type of input source.

Connect any other line level audio inputs to the LINE 4 (21) and LINE 5 (20) connectors on the rear panel

using good quality RCA leads. Since RM series amplifiers have a mono output, stereo signals will be summed

together.

Further mixer-amplifiers or slave amplifiers can be connected from the rear LINE OUT sockets (19), again

using a good quality RCA lead. This output carries the full mix of all channels 1-5 as fed to the speakers.

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.

Connect the "100V" (18) output terminal to the positive (+) connection of the speaker and "COM" output (16)

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 tappings 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.
