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.

How to program key functions (RM-SR777)
The functions of remote control units from other manufac-
turers can be memorized (programmed) by the RM-SR777.
Learning buttons @ “A” to "X" can be programmed with up
to 24 key functions, with the mode select switch @ set to1
and 2, for a total of 48 key functions.
Example: For button @ "A", Mode 1, ta memorize the
“PLAY” control function of a remote control unit
1. Select Mode 1 with @ Mode select switch.
2. Set the @ USE/LEARN switch to the LEARN pasition.
3. Put the two remote controls on a table with the transmis-
sion window of the remote control the functions of which
are to be learned ayainst the signa! receiving window at the
rear of the RM-SR777. Leave a distance of about 2 — 4
inches (6 — 10 cm) between them
4. Press button ‘A’ of the RM-SR777 and release it. The
SEND/LEARN indicator wilt blink.
(lf @ ERROR indicator lights at the same time, a func-
tion has already been memorized in @ "A". At this time, if
the button is depressed continuously, the previously
memérized function will be erased and it will be ready to
memorize the new function. If the previous function is still
required, select another button, @ "B" to “X"".)
5. While the SEND/LEARN indicator is blinking (for about 10
seconds}, press the button of the other remote control unit
the function of which is to be memorized (“PLAY"’ in this
case}.
When memorizing a setting, both the ERROR and SEND/
LEARN indicators light. if the ERROR indicator goes out
and only the SEND/LEARN indicator remains lit, it shows
that the memorizing operation has been completed
Keep pressing the button of the other remote control unit
while the ERROR indicator is lit
At this time, if the SEND/LEARN indicator does not blink
and only the ERROR indicator lights, the operation has
not been completed, After the indicator goes out, retry the
operation from step 4
6. To memorize other functions into other learning buttons
of the RM-SR777, repeat steps 4 and 5 after the SEND/
LEARN indicator has gone out.
7. To operate these buttons after the memorizing operation
is complete, set the @ USE/LEARN switch to the USE
position, Also, when functions have been memorized in
both Modes 1 and 2, first set @ mode select switch to the
required mode, then press the desired button
Notes:
© in step 4, if the ERROR indicator lights when one of the
learning buttons is pressed, it shows that the incorrect but-
ton has been pressed. Select another button.
@ In step 5, be sure to perform the memorizing operation
while the SEND/LEARN indicator is blinking (for about 10
seconds).
After the indicator goes out, the memorizing operation is
impossible. In such a case, repeat operations from step 4.
@ With certain remote control units, functions may not be
memorized correctly by the RM-SR777.

OPERATION WITH THE REMOTE CONTROL UNIT (RM-SR777/RM-SR777S)
Refer to page 23 for the diagrams.
A “COMPU LINK’ component (such as an amplifier.
receiver, tuner, CD player, cassette deck, turntable or DAT
deck) has one or two COMPU LINK-1/SYNCHRO jacks on
its rear panel
The RM-SR777/RM-SR777S Remote Contro! Unit can be
used to operate any “COMPU LINK” components connect-
ed to the receiver, without you having to press any front
panel buttons.
For example, when the CD player “PLAY” button on the
remote control unit is pressed, the CD player starts playing
automatically while the previous program source com-
ponent stops automatically.
Point the RM-SR777/RM-SR777S at the REMOTE SEN-
SOR window of the receiver (RX-777VBK/RX-777VSBK)
when using it.
tf the signa! from the RM-SR777/RM-SR777S requires two
or more components to operate simuttaneously, the opera-
tion may be slightly delayed
{f this happens, keep the button depressed unti! the requir-
ed components begin operation.
Certain other components receive signals directly from the
remote control; if these are too far from the receiver, it
may be difficult for them to detect signals from the
RM-SR777/RM-SR777S.
in this case, point the RM-SR777/RM-SR777§ at the re-
mote sensors of these components, and press the button
again
Since the RM-SR777/RM-SR777S does not have buttons
for the programming of preset stations or CD tracks, pro-
gramming the tuner or CD player, etc. must be performed
using the receiver or CD player's front panel buttons

COMPU LINK REMOTE CONTROL
SYSTEM
“COMPU LINK” Remote Control System is a system which
has been originated and developed by JVC (Victor Company
of Japan, Limited). The remote control units provided with
your COMPU LINK remote control components employ this
system. By operating the remote control unit in your hand,
you can not only contro! each component of your COMPU
LINK component but also enjoy such complicating perform-
ances as automatic source selection and synchronized record-
ing without any difficulty. Please operate the JVC remote
control unit yourself, and you will find how excellent this
system is. The following are the brief explanations of its
major performances.

If the attached remote cable is used to connect this unit to
other JVC components with COMPU LINK-1/SYNCHRO
terminals, sources can be switched with just one touch of this
units source selector buttons and the corresponding com-
ponent will start to play automatically. The source select
button of the remote control unit or the corresponding
component's PLAY button can also be used
When switching from one component to another, such as a
cassette deck, turntable or CD player, the previous component
will stop playing after about five seconds.
3. Synchronized recording (Fig. 33)
Synchronized recording refers to the process whereby the
cassette deck automatically starts recording in synchroniza-
tion with the CD player or turntable
Set the cassette deck to the REC/PAUSE mode following the
procedure in its instruction manual. For synchronized re-
cording from a CD player, push the PLAY button of the CD
player. The cassette deck enters the record mode the moment
the CD player starts and synchronized recording commences.
Synchronized recording stops automatically when the CD
player stops playing
