Using Advanced Sound Options

Note: The tone controls do not work when you select VIRTUAL mode.

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 Sur- round Sound, you need a stereo audio/video source.

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.

Dolby Pro Logic Surround

Dolby Pro Logic Surround puts you in the middle of the action. The cen- ter- 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 for surround sound systems. 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 3CH LOGIC when you play a Dolby Surround Sound program and do not have rear speakers.

To turn on Dolby Pro Logic Surround or Dolby 3CH Logic, press PRO LOGIC until PRO LOGIC appears on the display, then press SURROUND on the remote control followed by CENTER MODE to select NORMAL, WIDE, PHANTOM, or 3CH LOGIC. See “Sound Mode Adjustments (Remote Con- trol Only)” on Page 23 for information about each of these options.

Virtual Dolby Surround (Dolby Virtual/SRS)

Virtual lets you enjoy programs encoded with Dolby Surround while using only two front speakers. SRS creates a surround sound environ- ment from a material recorded in stereo. Select SRS 1 for the source that has broad frequency range such as classical or live music. Use SRS 2 for pop and jazz recording for smaller audio session atmosphere.

To turn on Virtual Dolby Surround, press VIRTUAL/SRS (VIRTUAL on the remote control) until the desired option — VIRTUAL, SRS1, or SRS2 — appears. Press VIRTUAL/SRS (VIRTUAL on the remote control) to turn off this feature.

DSP Effect

You can choose one of five DSP effects — HALL, JAZZ, DANCE, THE- ATER 1, THEATER 2, or DIALOG. Hall simulates a large concert hall, best suited for classical music. Jazz provides the acoustic effects gener- ally 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 programs. DIALOG enhances the frequencies of human voice, so you can hear the dialogs more clear- ly. To turn on a DSP effect, press DSP MODE until the desired option ap- pears on the display. Press DSP MODE to turn off the DSP mode. DSP OFF appears on the display.
