STAV-3470 Digital Synthesized Audio/Video Surround Receiver
(310-3033)              Advanced Sound Options        Faxback Doc. # 19457

Your receiver has five special sound options: Dolby Pro-Logic Surround, 
Dolby 3CH Logic, Studio-Effect Surround, Arena-Effect Surround, and
Simulated Surround.  These special options enhance 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 or Dolby 3CH Logic, press its buttons.
For studio effect, simulated surround, or arena effect, press SFC MODE
until the desired option appears on the display.  On the remote control,
press 3CH LOGIC to select Dolby 3CH Logic Sound and use SURR MODE for other
sound options.

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.  You
can find hundreds 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
ordinary 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 speakers.

Studio Effect

Studio Effect gives the effect of listening in a recording studio.  The
front speakers provide normal stereo, and the rear speakers provide a
subtly reverberated sound.  Select this mode when you listen to sources not
encoded with Dolby Surround.

Arena Effect

Arena Effect is ideal for sources such as live performances.  The front
speakers output the music, and the rear speakers output the sounds and
applause of the audience.  Adjust the delay time to obtain the best effect
of listening in halls of different sizes.

Simulated Surround

Simulated Surround simulates a surround effect when you listen to a
monaural (mono) source.

Sound Mode Adjustments (Remote Control Only) 

NOTES:  If you do not use a center speaker, the monaural signals are only 
        reproduced if you select PHANTOM. 

        You cannot select PHANTOM in the Dolby 3CH Logic Sound mode. 

Center Mode Setting

The center mode setting affects the center channel's bass signals.  It 
operates only when you select the Dolby Pro-Logic Surround or Dolby 3CH
Logic mode.  Slide AUDIO VCR/TV on the remote control to AUDIO.  Each time
you press CENTER MODE on the remote control, the setting changes, and the 
receiver's corresponding indicator lights: NORMAL - WIDE - PHANTOM for 
Dolby Pro-Logic Surround; NORMAL - WIDE for Dolby 3CH Logic. 

NORMAL -- Select this mode if you use a small center speaker.  The front
          left and right speakers play the center-channel bass sounds. 

WIDE -- Select this mode if you use a medium or large center speaker.  The 
        center speaker plays the center-channel bass sounds. 

PHANTOM -- Select this mode if you have no center speaker.  All  
           center-channel sound comes from the front left and right
           speakers. 

Test Tone

The test tone feature provides a test tone that lets you balance the signal
levels between all your speakers.  See "Center Level" and "Rear Level," 
below. 

To activate the test tone, select one of the surround sound modes then
slide AUDIO VCR/TV to VCR/TV and press TEST TONE.  The receiver sounds a 2-
second tone from the front left, center, front right, and rear speakers, in
sequence.  The center test tone sounds only when you select the Dolby Pro-
Logic Surround or Dolby 3 CH Logic Sound mode. 

In the Dolby 3CH Logic Sound mode, the receiver sounds a 2-second tone from
the left, center, and right speakers, in sequence. 

Press TEST TONE again to turn off this feature. 

Center Level 

Slide AUDIO VCR/TV to AUDIO.  Then press -CENTER+ to adjust the center  
speaker sound level while in the Dolby Pro-Logic Surround or Dolby 3CH
Logic mode. 

NOTES:  Use the VOLUME control to adjust the overall sound level. 

        Set the center mode to a selection other than PHANTOM before
        adjusting the center level. 

Rear Level

Slide AUDIO VCR/TV to VCR/TV.  Then press -REAR+ to set the rear speakers' 
sound level while in the Dolby Pro-Logic Surround or Simulated Surround
mode.

Delay Time

In the Simulated Surround and Dolby Pro-Logic Surround modes, the receiver 
slightly delays the sound going to the rear speakers.  You can change the 
delay time from 15 to 30 milliseconds (ms) in 5 ms steps.  Adjust this for 
the best surround effect. 

Slide AUDIO VCR/TV to VCR/TV.  Then press and hold DELAY TIME to change the
delay time.  The receiver displays the selected time. 

NOTE:  For Dolby Pro-Logic Surround, the delay is preset to 20 mS.
