Unpacking

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

Short Form Instructions

1. Do not connect the AC power until step 6. The ac mains power switch should be in the off position.

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

3. Connect an appropriate line level input signal to the balanced XLR 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 ac mains power switch in the off position, connect to an appropriate AC source.

7. Depress the ac mains power switch to the on position. The indicator ‘POWER’ will illuminate dimly and then
fully after a few seconds.

8. The product is ready for operation. Slowly increase the level control to the desired operating level. Avoid
illuminating the clip 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 clip 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

amplifiers) that produce heat.

9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades

with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and

the point where they exit from the apparatus.

11. Only use attachments/accessories specified by the manufacturer.

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. HANDLES

These are provided for easy transporting and installing into equipment enclosures or racks.

2. SCREW FOR DUST FILTER REMOVAL

To avoid unnecessary dust particles being drawn into amplifier, a removable dust filter has been fitted to the
front panel.

3. LEVEL CONTROL

This control adjusts the level(amplitude) of the input signal for each channel. In stereo or parallel mode the
knobs will determine the signal level independently for each channel. In the bridged mono mode only
channel A knob will be determine the signal level, while channel B disabled.

4. LEVEL INDICATOR

These indicators should illuminate during normal operation when there is an output signal.

5. PROTECTION/CLIP INDICATOR

This warns of a problem when illuminated. Reduce the level of the device which supplies signal to the
amplifier or reduce the level control(s) on the amplifier. This should not be continuously illuminated during
normal operation, but may flash occasionally. Also this indicates protection occurred like the amplifier over
heated, output shorted, over loaded and unexpected DC voltage output, which result the amplifier shutdown.
When protection released, the amplifier should be recovered.

6. POWER INDICATOR

This confirms the amplifier is switched on and receiving AC mains power when illuminated. When switched
on, the indicator is illuminated dimly for stand-by and then fully illuminated with prot/clip indicator for mute
status, after that, only this illuminated fully activating the amplifier.

7. POWER SWITCH

he position of this switch determines whether the AC mains power is on or off. The power-on status is confirmed by

T
the illuminated power indicator.
Amplifiers are always the last item in a system to be turned on. It is generally a good idea to reduce the level controls
before applying AC mains power.

1. AC CORD

Connect this product to an appropriate AC main power source.

2. OUTPUT CONNECTORS

4 Pole speaker sockets are provided. Bridged mono operation requires a different method of connecting the
speaker cables than stereo operation. Be sure that the amplifier is in the correct mode before connecting the
speaker load. Please refer to the output connection drawings.

3. MODE SELECTOR SWITCH

Move this switch to select the stereo, parallel or bridged mono position as needed for the application. The
stereo mode is most common. Channel A input provides signal through the amplifier to the channel A
output. The channel B input provides signal through the amplifier the channel B output. The parallel mode
uses the channel A input provides signal through the amplifier to both the channel A and channel B outputs.
No input will be supplied to channel B in the Parallel mode. The bridge mono mode combines both channels
to create one larger mono channel. Input signal applied to channel A will provide signal through the
amplifier to the positive terminals of channel A and channel B. Do not connect any signal to the channel B
input or any loads to the negative outputs.

4. VOLTAGE GAIN SELECTOR SWITCH

You can drive the amplifier with different gain structure, 1.4V, 32dB or 26dB, which is possible the amplifier
to accept a various input level.

5. 3-Pin Euroblock Input Connectors

These connectors are used for balanced or unbalanced input signals. For parallel mode or bridged mode,
use INPUT 1 only.

V2-5000

PROFESSIONAL POWER AMPLIFIER

6. Combination XLR, 1/4” TRS Input Connectors

hese connectors are used for balanced or unbalanced input signals, and are wired in parallel with the

T
Euroblock connector.

7. CLIP LIMITER SWITCH

The clip limiter reduces the internal operating level of the amplifier as necessary to insure that signal peaks
do not overdrive the amplifier, causing distortion or damage to the amplifier or loudspeakers. It is
recommended to leave this switch to the “ON” mode to reduce distortion and help to provide protection to
the loudspeakers.

8. HIGH PASS FILTER SWITCH

Select the switch position that is suited for your application the most. The off position allows full frequency
range signals to reach the loudspeakers. The 30Hz position reduces the signal amplitude below 30Hz to
conserve power and help protect the loudspeakers. The 50Hz position reduces the signal amplitude below
50Hz to conserve power and help protect the loudspeakers.
