Listening to an External Source

If other audio component(s) are connected to this system (see page 16) You can hear the external source through the speakers of this system.

1.You can press the TV or Video button on the front panel of the unit or the Function button on the remote to select the desired external source directly.

2.Operate the component which you wish to listen to and is connected to this system.

3.Adjust the volume level by pressing the VOL ￿￿ /￿ ￿ button on the front panel or remote control of this system.

Mute Control

To temporarily shut off the sound from the speakers press the MUTE button on the remote control. The "MUTING" indicator flashes on the front panel display.

Press the MUTE button again to cancel Mute and restore the sound. The "MUTING" indicator disappears.

Night Playback Mode (Front Panel Only)

This feature provides for additional Dynamic Range Compression during playback of a DVD movie. Press the NIGHT button on the front panel to switch the night function ‘ON’. The sound level will be reduced but you will still have the proper balance of high and low frequencies to maintain the realism of the special effects. Press the NIGHT button again to switch the night function ‘OFF’ and resume the normal sound level. This feature is useful when you watch a DVD movie late at night and do not wish to disturb others.

Speaker Configuration Setup (Front Panel Only)

As long as you are using the 6 original speakers that were supplied with this system, you should not change the Speaker Configuration Setup. The default Speaker Configuration setup sends only the mid-range and high frequencies to the satellite speakers and all the low frequency bass sounds to the subwoofer. If you ever decide to replace your front left/right, center or rear satellite speakers with larger full range speakers that can handle low frequency bass sounds you would use the SPEAKER Configuration SETUP button and the SELECT button on the front panel to change the front left/right, center, or rear settings from “Small” to “Large”. If you change the front left/right, center, and rear speaker setup from “Small” to “Large”, the system will automatically send low frequency bass sounds to these speakers as well. In this case you could also use the SPEAKER Configuration SETUP and SELECT buttons to shut the subwoofer ‘Off’, and to adjust the rear speaker delay from 15ms to 30ms. See page 36 for more details.

Headphone Jack

Connect a set of stereo headphones to this jack for private listening without disturbing others. The speakers are automatically disconnected when headphones are in use. You must use a headphone with a full size plug (¼”/6.25mm diameter).

￿When using headphones always set the volume control to a low level before putting the headphones on. Then put the headphones on and very gradually increase the volume to a comfortable listening level.
