Using Advanced Sound Options

Your receiver has three special sound options: Dolby Pro Logic Surround, SFC Effects, and 5-D Theater. These special options enhance the sound you hear from a program source.

Notes:

To get the full benefit from programs encoded with Dolby Surround Sound, you need a stereo VCR.

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 activate Dolby Pro Logic Surround, press DOLBY PRO LOGIC (or PRO LOGIC on the remote control). For Dolby 3CH Logic, repeatedly press the remote control’s CENTER MODE button until 3CHLOGIC appears on the display. For SFC effects or 5 D Theater, press SFC MODE or 5-D THEATER until the desired option 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 ap- propriate speakers, making you feel like you are really there. You can find hun- dreds of movies, television shows, and compact discs produced with Dolby Surround.

Dolby 3CH Logic

Dolby 3CH Logic produces a more spacious sound field than is possible with or- dinary stereo playback by combining the front and rear speaker sounds. Select this mode when you play a Dolby Surround Sound program and do not have rear speakers. The rear channel’s sound is sent to the front left and right speak- ers.

SFC Effects

You can choose one of four SFC effects — HALL, JAZZ, STUDIO, or ARENA. Hall Effect simulates a large concert hall, best suited for classical music. Jazz Effect provides the acoustic effects generally heard in jazz clubs. Studio Effect gives the effect of listening in a recording studio. Arena Effect is ideal for sourc- es such as live performances. Try each setting and find the best effect for the programs you want to listen.

5-D Theater

5-D Theater provides clearer and more dynamic sound effects by outputting au- dio signals through the rear channel to simulate the stereo sound, compared with a standard surround system which provides only monaural signals to the rear speakers. Select 5-D PRO for sources encoded with Dolby Pro Logic, or select 5-D SURR. for normal stereo sources.

Note: 5-D Theater Surround (5-D SURR.) produces stereo sound from the front speakers, enhanced with simulated surround sound from the rear speak- ers. The center channel does not operate.
