Using Advanced Sound Options

Your receiver has four special sound options: Dolby Pro Logic Surround, Dolby 3CH Logic, DSP Effect, and Dolby Virtual. These special options enhance the sound from a connected program source.

Notes:

•To get the full benefit from programs encoded with Dolby Surround Sound, you need a stereo VCR or DVD/LD player.

•Dolby Surround does not operate correctly if the signal passes through a graphic equalizer. If you connected an equalizer to the TAPE 2 MONITOR jacks, do not select TAPE 2 MONITOR when you listen to Dolby Surround signals.

To turn on Dolby Pro Logic Surround or Dolby 3CH Logic, presson the remote control until PRO LOGIC, THEATER 1, or THEATER 2 appears on the display, then press SURROUND followed by CENTER MODE to select NORMAL, WIDE, PHANTOM, or 3chLOGIC. See “Sound Mode Adjustments (Remote Control Only)” on Page 22 for information about each of these options.

For Dolby Virtual, press DOLBY VIRTUAL (VIRTUAL on the remote control) to turn

this feature on or off. To turn on a DSP effect, pressuntil the desired option (see below) appears on the display.

Dolby Pro Logic Surround

Dolby Pro Logic Surround puts you in the middle of the action. The center- and rear-channel speakers add incredible realism by directing the sound to the appropriate speakers, making you feel like you are really there. Pro Logic is the standard.

Dolby 3CH Logic

Dolby 3CH Logic produces a more spacious sound field than is possible with ordinary stereo playback by sending the rear channel’s sound to the front left and right speakers. Select 3chLOGIC when you play a Dolby Surround Sound program and do not have rear speakers.

Dolby Virtual

Dolby Virtual lets you enjoy programs encoded with Dolby Surround while using only two front speakers.

DSP Effect

You can choose one of five DSP effects — HALL, JAZZ, DANCE, THEATER 1, or THEATER 2. Hall simulates a large concert hall, best suited for classical mu- sic. Jazz provides the acoustic effects generally heard in jazz clubs. Dance gives the effect of a discotheque. Both theater modes provide the effect of a movie theater. THEATER 1 sounds like a large movie theater. THEATER 2 seems like a smaller theater. Try each setting to find the best effect for your pro- grams.
