cator
Use this button in conjunction with the sound source being
reproduced. This will rotate one step at a time through the
following pattern each time this button is pressed:
r DOLBY PRO LOGIC + HALL > OFF (Bypass) —
DOLBY
PRO LOGIC : When the sound source features the DOLBY
SURROUND trademark.
HALL : Create a concert-hall effect.
OFF
(Bypass) : When you are not using surround sound. When
this is pressed, no sound is produced from the
center and rear pre out and rear (surround)
speakers.
These modes can be changed with the remote control transmitter
by using the surround mode button.
M Delay Time Button (DELAY TIME) and indicator
You can change the delay time for the sound from the rear
(surround) speakers. Pressing this button changes the delay
time every 5 msec during a period of 15 ~ 30 msec in Dolby
Pro Logic, and every 5 msec during 5 ~ 40 msec in Hall.
This condition is shown ‘n numeric values on the display.
Dolby Surround delay time ts specified at 20msec. It is recom-
mended that initial Dolby Surround delay be set at 20msec, and
adjustment to either 15 or 30 is possible via the control. By
adjusting the delay time, and carefully adjusting Master Volume
Level, Center Volume Level and Rear Voiume Level, the apparent
acoustic size of your listening room can be enlarged or reduced.
Adjustable delay time allows you to tailor the acoustic size of
your listening environment to match the sonic characteristics
of the audio program. Use a longer delay for targer acoustic
spaces, such as concert halls, cathedrals, etc. Use a shorter delay
to simulate the size of a small club or cabaret. Respective delay
times can be memorized for DOLBY PRO LOGIC and HALL.
This operation can also be performed using the delay time button
of the remote controi transmitter.
NOTE: s
If you are in surround mode and change the delay time, but the
rear (Surround) speakers are not connected, nothing will happen.
However, even under these conditions, each time the delay time
button and surround mode button are pressed, front speaker
muting will occur and sound will disappear momentarily. This
is not a malfunction.
