Before Using the Unit

Read before operation

• Be careful to avoid injury when moving the unit, due to its weight. Get someone to help you if necessary.
• To protect easily scratched furniture, you may apply the felt pads supplied with the unit to the feet.
• As the unit may become warm during operation, always leave sufficient space around the unit for ventilation. The ventilation holes should not be covered. Make sure there is at least 20 cm (8") of space above and at least 5 cm (2") of space on each side of the unit. Do NOT place anything on top of the unit.
• The voltage supplied to the unit should match the voltage that is printed on the rear panel. If you are in any doubt regarding this matter, consult an electrician.
• Choose the installation location of your unit carefully. Avoid placing it in direct sunlight or close to a source of heat. Also avoid locations subject to vibrations and excessive dust, heat, cold or moisture.
• Do not place the unit on an amplifier or any other device that generates heat.
• Do not open the cabinet as this might result in damage to the circuitry or electrical shock. If a foreign object should get into the unit, contact your dealer or service company.
• When removing the power plug from the wall outlet, always pull directly on the plug, never yank the cord.
• Do not attempt to clean the unit with chemical solvents as this might damage the finish. Use a clean, dry cloth. o Keep this manual in a safe place for future reference.
• If a TV is turned on near the unit while the unit is also on, lines might appear on the TV screen depending on the frequency of the TV broadcast. This is not a malfunction of the unit or the TV. If you see such lines, move the unit and the TV further apart.

Maintenance

If the surface of the unit gets dirty, wipe with a soft cloth or use diluted neutral cleaning liquid. Be sure to remove any fluid completely. Do not use thinner or alcohol as they may damage the surface of the unit.

Basic Operation

Power ON / OFF

Connect the power cord and signal cables to the unit. Then, press the POWER button on the front panel to turn the unit on (). The power indicator on the front panel is on and the unit is in normal operating mode now.

To turn the unit off, press the POWER button on the front panel. The button is set to the off position (), and the power indicator and eventually the unit are off. Disconnect the AC power cord from the main outlet when the appliance is not used for a long period of time.

Input switching

To switch to the input port you want to use, press the corresponding signal selector button on the front panel or the INPUT k or j button on the remote control. The corresponding input status indicator will light accordingly.

Volume adjustment

You can adjust the volume setting by using the VOLUME knob on the front panel of the unit. To increase the volume, turn the knob clockwise. To reduce the volume, turn the knob counterclockwise. You can also use the VOLUME + or – button on the remote control to adjust the volume.

Using the VOLUME knob, set the volume to the minimum each time before turning off the unit to prevent damage to your loudspeakers when turning off and on the unit. After turning on the unit, use the VOLUME knob or VOLUME + button on the remote control to gradually increase the volume level.

Output protection

When the output of the power amplifier is overloaded, the relay of the protection circuit of the power amplifier will be disconnected. All indicators on the panel will be on at the same time and the volume will be turned down automatically. At this time, turn off the unit's power and eliminate any overload cause. In about 5 minutes, turn on the unit again to check for normal operation.

Mute

Press the MUTE button on the remote control to mute the sound output from the connected loudspeaker systems. While the sound is muted, the input status indicator for the selected input source blinks.

In mute mode, press the MUTE button on the remote control again to return to normal playback mode.
