Safety instructions

When using this electronic device, basic precautions should always be taken, including the following:

1. Read all instructions before using the product.
2. Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink, in a wet basement or near a swimming pool etc).
3. Use this device when you are sure that amplifier has a stable base and it is fixed securely.
4. This product, in combination with loudspeakers and amplifier may be capable of producing sound levels that could cause permanent hearing loss. Do not operate for a long period of time at a high volume level or at a level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should consult with otorhinolaryngologists.
5. The product should be located away from heat sources such as radiators, heat vents, or other devices that produce heat.
6. The product should be connected to a power supply that is described in the operating instructions or are marked on the product.
7. The power supply should be undamaged and never share an outlet or extension cord with other devices. Never leave device plugged into the outlet when it is not being used for a long period of time.
8. Care should be taken that objects do not fall into liquids and liquids would not be spilled on the device.
9. The product should be serviced by qualified service personnel if:
   • The power supply or the plug has been damaged.
   • Objects have fallen into or liquid has been spilled on the product.
   • The product has been exposed for ain.
   • The product has been dropped or the enclosure damaged.
10. There are some areas with high voltage inside, to reduce the risk of electric shock do not remove cover of the microphone receiver or power supply. The cover should be removed by the qualified personnel only.

CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN

Front panel functions

VOLUME CONTROLS
Rotary knobs for adjusting the volume level of the selected channel.

LED INDICATORS

The power LED indicator illuminates when the power is turned “ON”:

The signal LED indicator illuminates when the input signal is greater than -14 dBu is present.

The clip LED indicator when the input signal is greater than +3 dBu is present.
Occasional blinking is acceptable, but if LED lights on more than intermittently, turn down either the power amplifier level or reduce the output level of the preceding component to avoid audible distortion.

POWER SWITCH
Switch amplifier power ON or OFF.

Rear panel functions

MAINS POWER CONNECTOR
Power connector for mains power.

AMPLIFIER OUTPUT CONNECTORS
Audio outputs designed to connect speakers by using Speakon type connector.

AMPLIFIER INPUT CONNECTORS,
Input connector designed to connect external audio signals.
AMPLIFIER LINK CONNECTORS
Connect outgoing audio signal from input connectors to additional amplifier. Input and link connectors are connected with each other directly.

OPERATION MODES
There are 3 available modes of operation: stereo, bridge, and parallel. Turn off the amplifier before switching these modes.

Stereo   mode: This is the general mode. In this mode all amplifier channels are separate from each other, so totally four outs can be used. In this mode all four inputs require audio signal and all volume controls are active. The minimum loudspeaker’s impedance should be no less than 20.

Bridge mode: This mode combines the power from two channels to drive a single loudspeaker. Only input 1 and input 3 require audio signal. The minimum loudspeaker’s impedance should be no less than 40. Give attention to the wiring diagram placed on the amplifier rear panel before enabling Bridge mode. Bridge mode requires specific wiring,

Parallel mode: This mode allows operating in parallel two channels with the same audio signal. In this mode two channel inputs are internally connected, so only input] and input3 require audio signal but both volume controls are active. Do not use parallel mode then feeding the amplifier with four separate audio signals. Please note that only amplifier inputs are connected in parallel.
Do not connect output connectors in parallel! This is not an output parallel mode.
