cal Code, ANSI/NFPA No. 70-1984, provides
information with respect to proper grounding of
the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, size
of grounding conductors, location of antenna dis-
charge unit, connection to grounding electrodes,
and requirements for the grounding electrode. See

TWO VOLTAGE SELECTOR SWITCHES
Only multi-voltage models are provided with these switches. U.S.,
Canadian, European, U.K. and Australian models are not provided with
these switches.
Mains voltages in Saudi Arabia are 127 V and 220 V only. Never use
this model with 110 V setting in Saudi Arabia.
The line voltage selector switches are on the rear panel. Before your
model is shipped from the factory, these switches are set to the power
requirements of the destination. Check that they are set properly before
plugging the power cord into the household wall socket. If the voltage
is not properly set or if you move to an area where the voltage
requirements differ, adjust the selector switches as follows.
1. Use a medium-size screwdriver.
2. First, insert a screwdriver in the groove of the voltage selector at
the right, and adjust so that the tip of the groove points to the voltage
value of your area.
3. Next, insert a screwdriver in the groove of the voltage selector at
the left and adjust until the voltage is the same as at the right.

‘The large volume knob contributes to operational convenience and
positive response. You can even operate it via remote control. When
you change the volume setting using the remote, the knob turns by
itself, making it easy to keep track of the current setting.
e ENHANCER, SPLIT-SCREEN FUNCTION
The built-in detail-type enhancer is beneficial when making copies of
VCR tapes. Also, by using the split-screen function, you can simulta-
neously view the enhanced and original (non-enhanced) images. !n this
way you can select the optimum settings for enhancing the image.
This can be applied to both the monitor signal and the VCR 1, VCR 2
REC OUT signals, or to the VCR 1 REC OUT signal alone.
¢ VIDEO SIGNAL SELECTOR (Simulcast function)
Allows free combination of various audio video sources during playback
and over-dubbing, enabling you to produce your own original video
program.
¢ MULTI-ROOM REMOTE JACK
An input jack is provided on the rear panel for the Multi-room Remote
control.
ACCESSORY ITEMS
¢ TWO-WAY VCR COPYING AND MONITORING
VCR 1 + VCR 2: Copying of video cassette tapes can be performed
in either direction.
VDP/CDV, TV, VCR 3, VIDEO ~ VCR 1, VCR 2: VCR 1 and VCR 2
can be used for recording from units connected to the VDP/CDV, TV,
VCR 3 and VIDEO jacks.
¢ VCR 1 RECORDING SELECTOR FUNCTION
You can record on VCR 1 from VDP/CDV or VCR 2, regardless of other
functions.
¢ ACOUSTIC MEMORY FUNCTION
Five types (A—E) of tone control settings can be preset. The settings
for loudness and flat tone response functions can also be selected
quickly.
¢ STATION CALL-LETTER DISPLAY FUNCTION
The call-letters of broadcast stations can be preset (up to four
characters).
After presetting, the display can show the broadcasting frequency and
the call letters depending on the preset letters (for example WBAC,
JAZZ, NEWS, etc.).
AUDIO/VIDEO PROGRAMMABLE REMOTE CONTROL UNIT
With the attached remote control unit you can operate any Pioneer audio
or video component bearing the al mark. Using additional learning
functions a whole AV surround system including a TV and VCR from
other manufacturers can be controlled. (Some manufacturers’ remote
control systems, however, are not suitable for programming.)

SURROUND EFFECT
This unit has a built in surround processor for adding presence and an
expansive effect to the sound.
© STADIUM:
Effective for a stereo but not a monaural source. The ‘“STADIUM” effect
creates efficient, reverberated sounds to obtain an expansive sound
field. For music sources like a rock concert, you can feel if you were
at the live concert seated very close to the stage. For sports programs
such as a baseball game, you can enjoy a powerful sound, thus obtaining
a stadium-like effect.
* SIMULATED SURROUND:
The “SIMULATED SURROUND” creates of reverberated and reflected
sound from the walls and ceiling similar to a concert hall. These sound-
effects added to the actual sound from the source make you feel as
if in a more expanded space. The different ranges of the expanded space
can be set by the Delay Time key. Set the Delay Time to 15 ms or 20
ms for a live-house concert. For chamber music, set to 20 ms. For
orchestral music, set to 30 ms. The ‘SIMULATED SURROUND” also
gives the effects on monaural sources by outputting the reverberated
sound from rear speakers while keeping the output sound from front
speakers as it is. Turn on the “SIMULATED STEREO” for a monaural
source to gain the effective surround playback.
* DOLBY SURROUND (VSX-7500S)
Choose this setting for movies and music (especially Video Discs and
video tapes bearing the J] mark) playback.
Dolby Surround decodes the surround information in the source signal,
providing a feeling of left-right and front-back movement to match the
action on screen.
Please note: if center channel is to be used, a separate amplifier is
needed.
Moreover, consider the sound quality of this amplifier so as not to
undercut the overall quality of sound.
¢
DOLBY
PRO
LOGIC
SURROUND
(VSX-9500S)
Choose this setting for movies and music (especially Video Discs and
video tapes bearing the oc mark) playback.
DOLBY PRO LOGIC SURROUND continuously detects the size and
direction of the dominant signal and cancels undesirable crosstalk,
thereby providing signal emphasis.
It makes you clearly perceive the directions where music comes from.
Real flow of sound also can be re-created naturally using this feature.
You can feel as if being in the outstanding and expansive sound field.

<ARB1173>
You can choose from the following four settings:
Center Mode Choices:
© OFF ~— Set to this position for PRO LOGIC CENTER SPEAKER level
balance adjustment. (See page 31.)
(When using a center speaker:)
¢ NORMAL — Low range frequencies, which have little effect on
directionality and positioning, are routed to the left and right front
speakers. So you can use a relatively small size speaker as the center
speaker.
¢ WIDE — If you use a large size center speaker, choose this setting.
The full frequency range of the Dolby Surround center channel, from
low to high, is routed to the center speaker.
(When not using a center speaker:)
* PHANTOM — The signal which would have been sent to the center
speaker is divided equally between the left and right front speakers.
When using DOLBY PRO LOGIC SURROUND, a delay time setting of
20 ms is commonly used. Use a different setting if you prefer.
Even if they do not bear the DQ] mark, some
video recordings may be Dolby Surround encoded.
DOLBY SURROUND mode can be used with stereo sources not encoded
with DOLBY SURROUND. Adjust the volume of each speaker to obtain
a suitable surround effect.
Choose the SIMULATED SURROUND mode if the source sound signal
is mono. Little or no sound will be heard from the surround speakers
if the STADIUM or DOLBY PRO LOGIC SURROUND mode is selected.
With DOLBY PRO LOGIC SURROUND, monaural source sound will be
heard only from the center channel at settings other than the PHANTOM
position.
