1. Power: Once the unit is plugged in, it is in either
STANDBY or ON. This button switches from STANDBY to
ON, or can be operated from the remote control. In either
state the receiver is NOT disconnected from the AC main
power supply.
2. LED: In the STANDBY mode the LED is RED, when ON
the LED is Off.
3. Speaker Switch: Press this button to mute the output to
all speakers.
4. Headphone Jack: Normally the speaker switch (#3) is
pressed to mute speaker output for headphone listening.
5. Video 3 Input: Audio or Video sources connected to
these jacks may be selected by pressing the VCR2 button
(16).
6. Dolby Pro-Logic: Press this button to engage Dolby
Pro-Logic sound decoding. All five speakers are active in
this mode.
7. Dolby 3 Stereo: Press this button to engage Dolby 3
Stereo; only the front and center loudspeakers are active in
this mode.
8. Hall: Press this button to create a surround image from a
2 channel recording.
9. Center Mode: Press this button to change the center
speaker effect between NORMAL, WIDE and PHANTOM
when in the surround modes.
10. Test Tone: The test tone is used to calibrate the volume
settings of the speakers. A static noise will be heard
cycling, in order, from the front left, center, right, and both
surround speakers. When the test tone is cycling, you may
adjust the volume level of the center and surround speakers
with the CENTER LEVEL or REAR LEVEL buttons on the
remote control. Press the Test Tone button once more to
return to normal mode.
NOTE: The test tone is used to calibrate the performance of
the system. When listening to an actual recording, the
volume level of the surround channels is generally much
lower than that of the front channels. In fact, when listening
to a movie, virtually all of the dialogue and a substantial
amount of the effects are reproduced through the center
channel.
11. By Pass: Press this button to engage traditional 2
channel Stereo listening. Only the front speakers will be
active.
12. AM/FM Tuner Selector: Press this button once to
select the tuner. Press it again to switch between AM and
FM.
13. CD: Press this button to select the CD player.
14. Tape: Press this button to select the Cassette tape
player.
15. VCR1: Press this button to select a VCR or video source
connected to the rear panel on the unit.
