ately limited in dynamic range and frequency bandwidth for the surround channel and thus only requires speakers of far lesser capabilities compared to the front channels. Dolby Digital, however, is a full range system with two independent surround channels and with dynamics equal to that of the front channels. For this reason it is advis- able to choose loudspeakers which are similar in power handling and performance capability to those of the front channels. If you are using only one pair of surround speak- ers, make sure to connect them to the Surround Rear outputs. If you choose to install another pair of surround speakers, locate them behind your listening position, and connect them to the Surround Back outputs. Surround Back channels add to the spaciousness and coherence of the sound field, but the Surround Rear channels must be present for the desired effect.

Many film soundtracks rely heavily on very low frequency sound effects which are difficult for normal or smaller hi-fi speakers to reproduce. To faithfully reproduce these low frequencies you can use a specially designed low frequency loudspeaker with its own built-in amplifier (“active subwoofer”). Because it is difficult to hear which direction very low frequencies are coming from, you only normally need one subwoofer and this can be placed virtually anywhere in the room. Dolby Digital uses a dedi- cated Low Frequency Effects (LFE) channel. If a subwoofer has been selected, the LFE channel will be fed to the sub- woofer output.

First you need to indicate which speakers are present in your system. Besides the Main speakers (Left & Right), these can include a Center, two Surround Speakers and a Subwoofer.

Call up the SETUP menu of the On Screen Display.

Select the SPEAKER SETTINGS.

Highlight PRESET and use the Left and Right arrow buttons to select the preset (PRESET 1, 2 or 3) that best applies to your setup. Select a preset based on speaker sizes, then use the Up and Down arrow buttons to adjust for the absence of Center, Surround speakers, or subwoofer.

Preset 1: Default Setting / Adjustment

Main

: LARGE / No Adjustment

Center

: LARGE / OFF

Surround

: LARGE / OFF

Subwoofer

: ON / OFF

In this mode, all speaker channels are large, i.e. full range, and the home theater system has a subwoofer. This preset is particularly useful for large rooms.

Preset 2: Default Setting / Adjustment

Main

: LARGE / No Adjustment

Center

: SMALL / OFF

Surround

: SMALL / OFF

Subwoofer

: OFF / ON

This preset is useful for a home theater system that does not have full range speakers. The bass frequencies from the center and surround channels are redirected to the main speakers.

Preset 3: Default Setting / Adjustment

Main

: SMALL / No Adjustment

Center

: SMALL / OFF

Surround

: SMALL / OFF

Subwoofer

: ON / No Adjustment

This preset is ideal for those systems using 5 small speak- ers combined with a subwoofer. The bass frequencies from each of these 5 channels are redirected to the subwoofer.

The Surround settings affect both the Surround Rear and Surround Back speakers.
