IMPORTANT SAFETY INSTRUCTIONS
TO REDUCE THE RISK OF ELECTRICAL SHOCK, NEVER OPEN THE UNIT. NO USER SERVICEABLE PARTS INSIDE.
WE RECOMMEND TAKING THE UNIT TO A QUALIFIED SERVICE TECHNICIAN FOR ANY REPAIRS.
• Do not expose this unit to any kind of moisture.
• Please ensure that the unit is situated in a properly ventilated area.
• Make sure cooling fan vents are free of obstructions.
• Replace fuse with one of the same type, size, and rating only.
• Do not attempt to operate this unit if the power cord has been frayed or broken.
• Do not attempt to break o or remove the ground prong. This prong is used to reduce the risk of electrical shock and re in case of an internal short.
• Do not operate this unit if it is damaged.
• This unit is intended for indoor use only.
• During long periods of non-use, disconnect the unit from power source.
• Always mount this unit in a safe and stable manner.
• Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to
the point of exit from the unit.
• To avoid unnecessary wear and to improve the unit’s lifespan, unplug the unit when not in use for extended periods of time.

1. Power On/Off Switch.
2. Channel A Signal Level Adjustment Knob: Controls the level of incoming signal. The actual voltage attenuation of the amplier is shown in
decibels. Turn the knob counterclockwise if the Clip LED remains on for more than 5 seconds (indicating the input signal is too strong).
3. Channel A LEDs:
Clip - Indicates that the amplier’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.
On - Indicates the power is turned on.
4. LCD screen displays signal level and temperature for each channel.
5. Channel B LEDs: See item 3 above.
6. Channel B Signal Level Adjustment Knob: See item 2 above.

Rack Mounting
The RPA14 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 RPA14 can also be “stack” mounted without a cabinet.
Setup

6
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.
In STEREO mode the amplifier is fed a full-range signal and outputs a specific left and right signal. Each
channel is fully independent and has a separate level control. Make sure the speakers’ impedance is no
less than 4 ohms.
In PARALLEL mode the channels are connected internally. On the RPA14 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.
