Safety precautions
Placement
Set the unit up on an even surface away from direct sunlight, high
temperatures, high humidity, and excessive vibration. These
conditions can damage the cabinet and other components, thereby
shortening the unit’s service life.
Do not place heavy items on the unit.
Voltage
Do not use high voltage power sources. This can overload the
unit and cause a fire.
Do not use a DC power source. Check the source carefully when
setting the unit up on a ship or other place where DC is used.
AC mains lead protection
Ensure the AC mains lead is connected correctly and not
damaged. Poor connection and lead damage can cause fire or
electric shock. Do not pull, bend, or place heavy items on the lead.
Grasp the plug firmly when unplugging the lead. Pulling the AC
mains lead can cause electric shock.
Do not handle the plug with wet hands. This can cause electric
shock.
Foreign matter
Do not let metal objects fall inside the unit. This can cause
electric shock or malfunction.
Do not let liquids get into the unit. This can cause electric shock
or malfunction. If this occurs, immediately disconnect the unit from
the power supply and contact your dealer.
Do not spray insecticides onto or into the unit. They contain
flammable gases which can ignite if sprayed into the unit.
Service
Do not attempt to repair this unit by yourself. If sound is
interrupted, indicators fail to light, smoke appears, or any other
problem that is not covered in these operating instructions occurs,
disconnect the AC mains lead and contact your dealer or an
authorized service center. Electric shock or damage to the unit can
occur if the unit is repaired, disassembled or reconstructed by
unqualified persons.
Extend operating life by disconnecting the unit from the power
source if it is not to be used for a long time.

Place on the side of or slightly behind the seating area, about one

Subwoofer
The subwoofer can be placed in any position as long as it is at a
reasonable distance from the TV.
Note that some experimentation can yield the smoothest low
frequency performance. Placement near a corner can increase the
apparent output level, but can result in unnatural bass.
Other connections are possible depending on your speaker system.

Customizing your receiver
12
RQT5818
Change the settings to suit your speakers and equipment and to
suit the environment in which the unit is to be used. Before making
any changes, read the following descriptions, note the factory
settings and ranges, and refer to the instructions for the speakers
and equipment.
The settings remain intact until they are changed, even after the
power is turned off.
Setting descriptions
SIZE
Change to suit the speakers you have connected.
LARGE: For speakers that can reproduce a full sound range,
particularly the bass range below 100 Hz.
SMALL: For speakers that cannot adequately reproduce the bass
range. This setting is sufficient for most speakers if you are
using a subwoofer.
NONE: For speakers you haven’t connected (center or surround).
The factory settings are: Front: LARGE
Center and surround: SMALL
For the subwoofer, select YES if you have connected one (factory
setting), or NO if you have not.
DISTANCE
Enter the distance of the speakers from the seating position so that
the sound from all the speakers (except for the subwoofer) reaches
you at the same time.
You can select distances between 1.0 and 10.0 m at 0.1 m
intervals.
The factory settings are: Front and center: 3.0 m
Surround: 1.5 m
FILTER
This setting allows you to change the cut-off for bass output from
the front speakers. If you set the front speakers to “SMALL”, the
filter is set to 100 Hz. Raise the cut-off if the bass from the front
speakers is unsatisfactory so that this bass is output through the
subwoofer.
You can raise the cut-off from 100 Hz to either 150 Hz or 200 Hz.
DR COMP - Dynamic range compression
Change this setting to view software at low volume (such as late at
night) and maintain audio clarity. This setting works with Dolby
Digital software. It reduces the peak level in loud scenes without
affecting the sound field.
OFF: The software is played with the original dynamic range
(factory setting).
STANDARD: The level recommended by the producer of the
software for household viewing.
MAX: The maximum allowable compression (recommended for
night viewing).
D-INPUT - Digital input
Change these settings to suit the connections you have made to the
three digital input terminals, COAX, OPT1, and OPT2 (\page 7),
so that the correct source is selected when you turn [INPUT
SELECTOR] (\page 18).
The factory settings are: CD: COAX
DVD: OPT2
TV: OPT1
DIMMER
This setting allows you to dim the unit’s display for better viewing in
a darkened room.
The factory setting is OFF (normal brightness).

Adjusting speaker output level

RQT5818
Preparations
Adjust the level of the speakers so they are the same apparent level
as the front speakers when you are sitting where you would
normally enjoy a source.
1Press [A] to turn on SPEAKERS A.
You cannot adjust output level when SPEAKERS B is on.
Press [SPEAKERS] to turn on
SPEAKERS.
2Press [TEST] to output the test signal.
DSP sound mode switches to SURROUND mode.
The signal is output from each speaker in order for about two
seconds each:
L: Front speaker (left)
C: Center speaker
R: Front speaker (right)
RS: Surround speaker (right)
LS: Surround speaker (left)
SW: Subwoofer
Speakers set as “NONE”or “NO”are skipped.
The test signal will not be output if DSP is defeated (\page 22)
or (SA-DX850 only) DVD 6CH INPUT is on (\page 19).
3Adjust the volume to the level
normally used.
Adjust the balance of the front speakers if necessary
(\page 20).
4Press [LEVEL] to select the speaker
channel to adjust.
The current level appears on the display.
Press again to change the speaker channel.
Speakers set as “NONE”or “NO”are skipped.
5Press [–] or [+] to adjust the level to
the same apparent level as the front
speakers.
C, RS, and LS can be adjusted between –10 dB and +10 dB,
with zero being the current level of the front speakers.
SW can be set to MIN, between 1 to 19, or MAX.
Repeat steps 4 and 5 for each speaker channel.
6Press [TEST] to stop the test signal.
For your reference
Subwoofer output is easily influenced by the source played. You
can achieve better results by adjusting its output while listening to a
source (\page 21).

Changing the recognition mode
The digital sound processor (DSP) in this unit can decode Dolby
Digital and DTS digital signals. It automatically determines the type
of signal, PCM, Dolby Digital, or DTS, and processes it accordingly.
The DSP can add surround-like effects to stereo sources (analogue
or PCM signals).
Choose from the STEREO, SURROUND, or SFC modes.
The DSP may interfere with radio reception. You can turn it off if this
occurs (\page 22).
Output is in stereo when you turn the DSP off so sound is only
heard through the front speakers.
¡PCM with a sampling frequency of 44.1 kHz is the digital signal
format normally found on CDs. Some DVDs also use this format
but often with a higher sampling rate.
¡This unit cannot process other digital signal formats, such as
PCM signals with sampling frequencies of 96 kHz and 192 kHz
and MPEG.
¡SA-DX750 cannot process DTS signals.
Note
Use this mode to play digital or analogue stereo sources or to play
surround sources through two speakers. When surround sources
are played in this mode, the sounds intended for the other speaker
channels are played through the front speakers.
Select this mode when you are playing a digital surround source
[Dolby Digital or (SA-DX850 only) DTS] or an analogue source that
is recorded with Dolby Surround (VCR, for example).
STEREO mode
SURROUND mode
In rare cases, the unit may have trouble recognizing the digital
signals on discs. With the PCM signals on CDs, this may cause the
beginning of a track to be cut off. Engage the PCM FIX mode if this
occurs.
(SA-DX850 only) With DTS, the signals may not be recognized at
all. Engage the DTS FIX mode if this occurs.
This mode does not need to be changed under normal
circumstances. Change it only if the unit appears to be having
trouble recognizing the software you are playing.
While the input source is selected and digital input is engaged:
Press and hold [DIGITAL INPUT].
The current mode is displayed. Press again to change the mode.
Each time you press the button:
AUTO /PCM FIX /DTS FIX
↑
AUTO ,/ PCM FIX
When a FIX mode is on, the unit cannot process other signals. This
may cause noise to be output. Select “AUTO”if this occurs.
The selected mode is stored even if the unit is turned off.

Adjusting the sound field
Enjoy an enhanced sound experience with greater presence and
