Features

  1. Power On/Off
  2. Channel A Signal Level Adjustment Knob: Controls the level of incoming signal. The actual voltage attenuation of the amplifier is shown in Turn the knob counterclockwise if the Clip LED on for more than 5 seconds (indicating the input signal is too strong).
  3. Channel A LEDs:Clip – Indicates that the amplifier’s output is within 3dB of clipping. Occasional blinking is acceptable, but if it remains on for more than 5 seconds you should turn down the level controls or reduce the output level of the input source to avoid audible distortion.Signal – Indicates that there is an input signal greater than 100mV.Protect – Indicates that the output connection is shorted, the load impedance is too low, or there is an internal malfunction.

Setup

Rack MountingThe RPA12 was designed for standard 19” rack mounting and requires 2U rack space. Use the included heavy-duty rack mount ears, 4 screws, and 4 washers for mounting to the front rack rail. Preferably, the side wall should be at least 2”from the sides of the amplifier and the back of the rack should be open. This will ensure a source of cool air to all sides. Be sure to support the rear of the amp, especially for mobile use where it will be subjected to strong vibrations. The RPA12 can also be “stack” mounted without a cabinet.

Configurations

Crossover and Mode SwitchesIn STEREO mode the amplifier is fed a full-range signal and outputs a specific len and right signal. Each channel is fully independent and has a separate level control. Make sure the speakers’ impedance is no less than 4 o/lms.

In PARALLEL mode the channels are connected internally. On the RPA12 Channel A is the dedicated input for use when in this mode. The signal input to Channel A will feed a mono signal to both channels. Each channel has a separate level control.

In BRIDGED mode, the amplfier operates as a one channel mono amp. The power from both channels is combined into one channel. As with parallel mode, the channels are connected internally and Channel A is the dedicated input. The signal input to Channel A will feed a mono signal to the positive binding post output terminals of each channel. The Channel B positive output is connected to the negative input of your speaker. The Channel A positive output is connected to the positive input of your speaker. This mode is primarily used when connecting subwoofers.

Set the switch to BYPASS when using full-range speakers.

Set the switch to SUB 80Hz or SUB 160Hz when using subwoofer(s). This will allow frequencies below 80Hz or 160Hz only.

Stereo

WARNING: Total impedance of  your speakers must not be less than 4 ohms.

Parallel (mono to speakers)

Parallel (mono to passive subwoofers)

Bridged (mono)

Link Out XLR

These set ups allow you to use the RPA12’s XLR Link Out ports to send the full range signal from the main amp to a secondary amp (diagram A) or directly to a powered sub (diagram B).

Troubleshooting

PROBLEM

SOLUTION

No power

  1. Make sure the unit is plugged in and the power switch is in the ON position.
  2. Check that the power cable is properly plugged into the wall socket.
  3. Check and replace the fuse if necessary.
  4. If people or equipment tend to step on and roll over or stretch your power cable it can get damaged. Check the power cable for damage. If the cable is damaged, discontinue using the unit until the cable can be repaired.

No sound

  1. Check that all appropriate cables and wires are plugged in correctly.
  2. Check the channel level settings.
  3. Check the volume settings on your input devices.
  4. Check mixer’s master and input volumes.
  5. Make sure you are using the proper cables.
  6. Make sure speakers are connected to the amp’s OUTPUT, not INPUT.
  7. Make sure mixer is connected to the amp’s INPUT, not OUTPUT.
  8. Make sure the mixer’s mute isn’t on.

Clipping light is on

  1. Turn down signal level controls (gain).
  2. Check impedance of speakers or subs.
