FRONT PANEL
@ POWER
ON: Press to turn the power on. To turn the power off,
press again. Even when the power is turned off, the POWER
STANDBY indicator remains lit unless the receiver is un-
plugged from the wall outlet.
STANDBY: Even when indicators other than POWER
STANDBY are not lit, the memory circuit operates and
preset and source select data, etc. are not fost and cannot
be altered by accident as long as the power cord is plugged
into an AC outlet. This is called the POWER STANDBY
mode. The preset data and the source select data are main-
tained even in the case of a power failure or when the
power is not applied does not exceed a couple of days.
Notes:
@ Even in the POWER STANDBY mode, this receiver con-
sumes a small amount of electricity (2 watts). To shut
off the power completely, disconnect the power cord.
@ POWER STANDBY indicator:
Connecting the power plug to the AC wall outlet causes
this indicator to light, indicating that the unit has been
set to the POWER STANDBY mode.
@ When the power is tuned on, the operation buttons may
not work correctly and abnormal! indications may appear.
lf this happens, unplug the power cord from the AC
outlet and insert it again.
@ 7-BAND SEA GRAPHIC EQUALIZER
The built-in graphic equalizer divides the audio spectrum
into seven frequency bands with center frequencies from
63 Hz to 16 kHz at intervals of 4/3 octave
When the S.E.A. level is set to “0” (center position}, the
frequency response is flat. The response can be varied by
+10 dB by raising or lowering the knob.
63 Hz: Raise to emphasize the very low bass response of
organs, drums, and contrabass. It produces stable and
solid sound with emphasis and eliminates the unclear
response at low frequencies when de-emphasized
160 Hz: Emphasize to obtain a more expanded iow fre-
quency sound, De-emphasize to eliminate unclear sound
caused by large or nearly empty listening rooms.
400 Hz: This frequency range is the base on which music ts
constructed. Emphasize to really put a punch in your
music.
1 kHz: Most effective in emphasizing or de-emphasizing the
human voice. Emphasize to cause the vocalist to be brought
to the foregrownd, or de-emphasize to cause it to recede
into the background
2.5 kHz: The human ear is most sensitive to this frequency
If the music sounds hard or metallic, de-emphasize it
6.3 kHz: Boost to add clarity to winds and strings. This
frequency band varies the tonal expression, and has most
influence on the subtleties of the music
16 kHz: Boosting this frequency range properly adds to the
delicacy of highs, with cymbals and triangles resounding
in a more ear-pleasing manner, and provides a feeling of
extension. This frequency band can also be used to com-
pensate for cartridge response since most moving-magnet
cartridges have their resonance peaks in the frequency
range from 10 kHz to 20 kHz
@OSEA
SEA SOURCE: Press this button to listen to S.€.A.-com-
pensated sound

LES
Fig. 17
1. A standard speaker arrangement for surround sound reproduction.
This configuration gives most effective surround sound with enriched
“presence’’.
Most suitable for playing program sources encoded with Dolby Surround
sound.
2. Place the surround speakers at the left and right sides of the listen-
ing position. With this configuration, the separation between the front
and rear may be slightly decreased, however, the extension of the
sound fieid will be much wider.
With this placement, set the surround speakers so they are higher than
listeners’ ears and direct them slightly downward to get a wider sound
field
3. Place four speakers in front of the listening position. Although the
feeling of movement will be slightly decreased when playing video
programs, it gives more natural width to the sound field.
This is suitable when you want a stable sound field (or ‘‘presence’’),
especially when playing normal stereo audio sources.
Note:
@ If the walls are made of hard wood or plaster, when the surround
speakers are placed facing towards the walls (reversing the placement
illustrated in the above examples 2 or 3), a more favorable effect may
be obtained.
Movie programs, etc. encoded with the Dolby Surround system are
produced so that the volume balance between the front channels
and the surround channels is set by the producer of the individual
movie. For this reason, it is recommended that you do not set the
level of the surround channel too high, to obtain a Dolby Surround
sound effect which is closer to that intended.
