Page 4: Introduction
These models have a constant voltage power amplifier allowing use at 70/100V or at low impedance of 4 Ohms. The PR-130A can deliver a power of 130 Watts, and the PR-240A a power of 240 Watts. They offer six inputs channels (terminal block/RCA) with independent level controls to facilitate the connection of sound sources. -

Page 8: Setup
Location: Take the unit out of its packaging (keep it for any return to the workshop). The PR-130A and PR-240A mixing amplifiers can be installed in a standard 19” equipment rack or on a shelf. To install the unit in a standard 19” equipment rack, please use the rack ears that are included with the unit. - Page 9 A simple way to represent a constant voltage is to divide the power in Watts of the amplifier by the number of loudspeakers used. For example, to connect ten loudspeakers to the output of a PR-130A amplifier, use a loudspeaker whose transformer provides a tap point of approximately 10 Watts.

Page 10: Connections
PR-130A / PR-240A Connections Connecting speakers Connect the speakers to the terminal block output connectors on the rear. Never turn on the amplifier when the speakers are not connected to the outputs. When using the 4 Ohm output, you must connect speakers with a minimum impedance of 4 Ohms (4 Ohms or more). - Page 11 PR-130A / PR-240A Connecting sound sources Then connect the sound sources to the terminal block input connectors on the back. If your console or source has Balanced outputs, use balanced three-conductor connections and connectors (you can use unbalanced connections, but you'll get better sound quality and less noise if you use balanced connections).
- Page 12 PR-130A / PR-240A Wiring guide Choose the input connector and the appropriate cable for each source. We recommend the use of pre-assembled or professionally assembled 22-to-24-gauge balanced cables. Figure 2.1 shows the connection diagrams for the different connectors. RCA input connectors can also be used as unbalanced inputs.
- Page 13 PR-130A / PR-240A Wiring guide - Continued CAUTION: Never use shielded cable for speaker output. Maintain correct polarity on output connectors. For each output channel, connect the output terminal block connector to the speakers. Use terminals marked COM and 4Ω / 8Ω for low impedance speakers, or use terminals marked 70V or 100V, and COM for high impedance speakers.

PR-130A / PR-240A Operations Signal input gain control The PR-Series mixer-amplifiers can accept balanced mic or line input signals, thanks to the gain selection switches (figure 3.1). Phantom power The PR-Series mixer-amplifiers can supply 48V DC phantom power to use condenser microphones on any of the mic channels. - Page 15 PR-130A / PR-240A Remote Microphone A RM6 remote paging microphone station can be connected to the PR-Series mixer-amplifiers. The RM6 remote microphone station can select from the 6 individual zones and play a pre-announcement chime. The RM6 remote microphone station should be connected using UTP CAT5/6, CAT6 is recommended for longer distance.
- Page 16 PR-130A / PR-240A Using the TELE-Paging function You can connect the PR-Series mixer-amplifiers to a business telephone system using the TELE PAGING connector allowing announcement paging from any telephone. Usually, the telephone system provides a dedicated output and has the ability to send a page using a certain extension number. Check the manufacturer's operating manual of the telephone system for operation detail.
