Notes on Use

Volume Setting

Before switching ON minimise the volume.  

Sudden, large output can damage the

speakers.

Volume Etiquette

To avoid disturbance in your neighbourhood,

enjoy your unit at an appropriate volume.

Remember that at night, even low volume

carries into surrounding areas.

Help to maintain a pleasant living

environment.

Speaker Cord Connection

Always connect speaker systems with

power OFF.

If a speaker cable is inadvertently shorted,

the protection circuit in the amplifier will

operate, and audio output will stop

temporarily.

In this event, disconnect the power cord

from the outlet, correct the shorted area

and reconnect the power cord to the outlet.

Power supply

This product is equipped with vibration

counter measures and a tone-quality

adjustment and has been designed to

provide a sense of integration when the

amplifier is placed on top of the power

supply.

The setup location has to be well ventilated

and dry.

Volume knob

Attach the volume knob to the amplifier as

shown in the following figure.
