Unpacking

Please take a few minutes to read this manual to familiarize yourself with important information regarding
installation, product features, and operation.

As with most electronic devices, ORIGINAL PACKAGING (OR EQUAL) IS REQUIRED in the unlikely event that
the product needs to be returned for servicing.

Short Form Instructions

1. Do not connect the AC power until step 6. The POWER switch should be in the OFF position.

2. Adjust both of the LEVEL controls to the fully attenuated position (turn counter-clockwise).

3. Connect an appropriate line level input signal to either the balanced XLR or the balanced 1/4" TRS (Tip-Ring­Sleeve) connector marked INPUTS.

4. Move the MODE selector to the desired position. The Stereo position is the most common.

5. Connect the OUTPUTS to the speaker load according to the mode of operation determined in the previous step.

6. With the power switch in the OFF position, plug in the supplied Universal AC power cord to the product and
an appropriate AC source.

7. Depress the power switch to the ON position. The power switch will illuminate.

8. The product is ready for operation. Slowly increase the LEVEL control to the desired operating level. Avoid
illuminating the PEAK indicator and do not apply too much power to the speakers.

9. Operate the product and the system in a manner which DOES NOT illuminate the PEAK warning indicator.

Environment

Never place this product in an environment which could alter its performance or reduce its service life. Such
environments usually include high levels of heat, dust, moisture, and vibration.

Important Safety Instructions

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including

12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus.

When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.

14. Refer all servicing to qualified service personnel. Servicing is required when the

apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.

1. LEVEL CONTROL

This determines the level of the input signal for each channel. In stereo mode the knobs will determine the
signal level independently for each channel. In the bridge mono mode only the channel 1 level control is used.

2. SIGNAL INDICATOR

This indicates the level of the input signal. This should be illuminated during normal operation.

3. CLIP INDICATOR

This LED warns of a problem in the system when illuminated. Reduce the LEVEL of the device which supplies
signal to the amplifier or reduce the LEVEL control(s) on the amplifier. This LED should not be illuminated
during normal operation.

4. PROTECTION INDICATOR

This LED warns of a problem in the system when illuminated. Reduce the volume and look for problems. It is
possible that the amplifier is too hot or the speaker impedance is too low. This LED should not be illuminated
during normal operation.

5. POWER INDICATOR

This LED indicates the amplifier is switched ON and receiving AC POWER when illuminated.

6. POWER SWITCH

The position of this switch determines whether the power is ON or OFF. The power-on status is confirmed by
the power indicator. Amplifiers are always the last item in a system to be turned on. It is a good idea to turn
down the level controls before applying AC mains power.

7. HANDLE

Handles are provided for moving and installing into equipment enclosures or racks.

1. BALANCED INPUT CONNECTORS

Each input channel is equipped with a 1/4" TRS and an XLR connector. Standard rules of interconnect apply.

2. MODE SELECTOR SWITCH

Move this switch to select either the STEREO or BRIDGED MONO position as needed for the application.

The Stereo mode is most common. Channel 1 input feeds the channel 1 output. The channel 2 input feeds the
channel 2 output.

The Bridge Mono mode combines both channels to create one larger mono channel. Input signal applied to
channel 1 will be available across the positive terminals of Channel 1 and channel 2. Do not connect the
channel 2 input or any of the negative outputs.

3. OUTPUT CONNECTORS

Binding Posts and Locking speaker connectors are provided. Bridged Mono operation requires a different
method of connecting the cables than Stereo operation. Be sure than the amplifier is in the correct mode
before connecting the speaker load.

4. FUSE

The fuse protects the amplifier by opening the circuit for the AC mains power in case of overload or
malfunction. If the fuse opens, the amplifier (and the various other components in the system) should be checked
for proper operation. If the fuse continues to open after verifying that the system is wired correctly and that an

overload has not occurred, the amplifier should be checked for proper operation by a service technician.

Mounting in a Rack

Mounting in a Rack

If multiple high-power amplifiers are mounted in a rack with poor ventilation, the heat from the amplifiers will
cause the interior of the rack (and the amplifiers) to become very hot, which may cause problems with amplifier
performance. If amplifiers are mounted in a rack without an open rear, you should use special care to help
ensure proper ventilation of the rack.

Here are suggestions to help keep the amplifiers properly ventilated:

1. Leave a space of at least 10 cm (4 inches) between the rear door of the rack and the rear panel of the amplifier.

2. Install a fan or blower in the rack to help cool the equipment.

3. Install blank (or vent) panels between amplifiers.
