Standard speaker setup for surround sound
● Front Right and Left speakers
These are the main speakers providing the front stereo effect of the sound image.
● Centre speaker
This produces a rich sound image by serving as a centre sound source for the front right and left speakers thus enhancing the sonic
movement.
● Surround Right and Left speakers
These add three-dimensional sonic movement and produce environmental sound associated with the background and effect sounds for
each scene.
● Subwoofer
Required to add powerful and heavy bass.
Speaker placement
Ideal speaker placement varies depending on the size, shape of your room and the wall coverings. Here is a typical example of speaker
placement and recommendations as shown.
Important points regarding speaker placement
Front Right and Left speakers and Centre speaker
- Place these three speakers all at the same height.
- Place each speaker so that it is aimed at the location of the listener’s ears when at the listening position.
- Try to place all the front speakers at the same distance from the listening position.
Surround Left and Right speakers
- Place these speakers so that their height is 3 feet (1 meter) higher than that of the listener’s ears.
Subwoofer
Ideally a subwoofer should always be located in front of the listening position between the Front Left and Right speakers. Since all rooms
vary, experiment with the placement of your subwoofer for the best overall sound image (placing a subwoofer in the corner of a room often
helps to disperse the sound).

CONNECTION
using just one video input on the TV (S-Video or RCA). Regardless
of the video component being played DVD or VCR, the picture will
always appear on the same video input of the monitor.
If you use both S-Video and RCA composite cables to connect
different video components to your unit, you must also use both
S-Video and RCA composite cables to connect the TV monitor to
your unit. For example, if you connect a DVD player to your unit
using S-Video cable and a VCR using an RCA to RCA composite
cable, you must also connect the TV to your unit using both types
of cables. This requires an S-Video cable from the S-Video monitor
out jack on your unit to an S-Video input on the TV (i.e. Video 1). In
addition, you must use an RCA composite cable from the
composite video monitor out jack on your unit to an RCA composite
video input on the TV but not the same input used for the S-Video
cable (i.e. Video 2). Using this type of dual cable video connection,
you will need to switch the TV video input source from TV to Video
1 to Video 2 depending on the video source being played-TV, DVD
or VCR.
When connecting video components such as DVD players, cable
boxes, satellite receivers and television/plasmas, you can use
different types of cables depending on how the video component is
equipped.
Video connections:
If the video component is equipped with S-VIDEO jacks, it is
recommended to connect to your unit or directly to the television
monitor using an S-VIDEO cable. S-VIDEO cables provide better
picture clarity and resolution. If the video component is not
equipped with an S-VIDEO jack, use a conventional RCA or RCA
composite cable to connect to your unit or connect it directly to the
television. The illustration here shows how to connect video
components to your unit.
Note:
When connecting more than one video component to your unit (i.e.
VCR and DVD player) it is easier to use either all S-VIDEO cables
or all RCA to RCA composite cables. This allows both video signals
(DVD and VCR) to be sent through your unit to the TV monitor
9
CONNECTION
CD, TAPE jacks
Connect the component with RCA to RCA cords.
Make sure to connect:
Audio connections:
Some video components are equipped with special digital audio
outputs (e.g. DVD players). If your video component is equipped
with a digital audio output, it is recommended that you connect to
your unit using a digital cable. Digital audio cables are required to
use the DTS and Dolby Digital surround sound modes. If you do
not use digital connections, your unit will only operate in Dolby
PRO LOGICII, MUSIC, THEATER, HALL and 5 Stereo surround
modes. There are two types of digital cables-coaxial (75 ohm) and
optical. Your unit is equipped with both types of digital inputs.
These inputs are labelled COAXIAL IN and OPTICAL IN on the
rear of the unit. Connect the video component outputs to any one
of the two digital inputs on your unit. If the video component is not
equipped with a digital output, use a dual RCA to RCA composite
audio cable to connect to your unit. Make sure to connect:
White plug to white jack (L: left)
Red plug to red jack (R: right)
White plug to white jack (L: left)
Red plug to red jack (R: right)
DIGITAL IN/OUT terminals
If the CD player or MD player has digital outputs, connect the
component with coaxial cables or optical cables.
DIGITAL IN to DIGITAL OUT (CD, etc.)
DIGITAL OUT to DIGITAL IN (MD, etc.)
Connect to any one of the DIGITAL IN terminals. When using
DIGITAL OPTICAL IN terminals, remove the caps from the
terminals. When you do not use them, leave the caps in place. To
record digitally, connect the source (CD player, etc.) to DIGITAL IN
and the recorder (MD, etc.) to DIGITAL OUT.
Note:
When an optical cable is used, remove the protection caps from
the component and your unit before attempting to insert the optical
cable. If not using an optical cable or if the cable is removed,
always re-install the protection caps to prevent dirt and dust from
entering the inputs. If using a coaxial digital cable, leave the
protection caps in both the video component and your unit.

shown on the multi-function display (Note: RDS only functions when the local radio station includes the RDS transmission within its signal
and when the signal is strong enough).
By pressing the “DISPLAY” button on the Remote Control, you can select the following RDS functions: PS, PTY, CT and RT.
a) PS (Program Service Name)
Press “DISPLAY” on the remote until “PS” appears. The current station name will be shown (Note: “NO PS” will be shown if the signal
from local radio station is not strong enough or if the local station is not transmitting RDS data).
b) PTY (Program Type)
Press ”DISPLAY” on the remote until “PTY” appears. The current name type of the program will be shown (Note: “NO PTY” will be shown
if the signal from local radio station is not strong enough or if the local station is not transmitting RDS data).
c) CT (Clock - Time)
Press “DISPLAY” on the remote until “WAITING CT” appears. After a short period the current time from radio station will be shown, e.g.
15:30 (Note: The Clock - Time will be only transmitted from local radio station once a minute, so you need to wait for less than 1 minute to
show the result. (Note: “NO CT” will be shown if the signal from local radio station is not strong enough or if the local station is not
transmitting RDS data).
d) RT (Radiotext)
Press “DISPLAY” on the remote until “RT” appears. Some radio stations broadcast simple text messages along with the RDS data which
will be shown on the display. (Note: “NO RT” will be shown if the signal from local radio station is not strong enough or if the local station is
not transmitting RDS data).

SPEAKER CONFIGURATION, DELAY TIME & DYNAMIC RANGE CONTROL
SPEAKER CONFIGURATION
It is important to configure your speakers correctly in order to get
the most from your AV Receiver. This versatile AV Receiver
provides the flexibility to experience multi-channel surround sound
without a center speaker. However, for best results with Dolby Pro
Logic II, DTS and Dolby Digital decoding, at least 5 speakers (Left,
Center, Right, Left Rear and Right Rear) should be used. (Note: As
with all surround sound configurations, we recommend the use of a
Subwoofer speaker to fully experience the Low Frequency Effect
encoded into most of today's DVD movies).
In the surround modes, the sound from the speakers should be
delayed slightly, relative to that from the front speakers.
The optimum delay time will depend on acoustic properties,
whether the walls and furnishings reflect or absorb sound, etc.
It is recommended that you try different delay times to obtain the
best effect. The delay is digitally synthesized.
For the highest sound quality with minimum noise and distortion,
the delay time can be set independently for each surround mode
using the DELAY TIME buttons, with the current setting shown in
the display.
BASS MODE
There are 2 preset speaker configurations based on the size of
your speakers.
Default is Mode 1.

DYNAMIC RANGE CONTROL
This button controls the compression range of sound track. If the
compression is large (DRC = 4/4), the sound effect is retarded to a
certain range. As a result, sound effect is not as excited as normal
range DRC = 0/4). It is useful when you want to movies at the late
night.

Press DYNAMIC on remote control repeatedly until the
desired compression range reached.
Press BASS MODE to select one of the 2 modes according to your
speaker's size.
(Note: Large speakers can fully reproduce low frequencies of
below 80Hz. Small speaker cannot reproduce low frequencies of
below 80Hz with sufficient volume. Refer to your speaker
specifications to select the correct size).
DELAY TIME
The delay time can be individually set for the Dolby Digital/Dolby
Pro Logic II modes using the DELAY (CENTER/REAR) buttons.
When you adjust the delay time in the Dolby Digital mode, an
additional 15 ms is automatically added to the surround channels in
the Dolby Pro Logic mode. The current setting is shown on the
display.

TEST TONE, LFE TRIMMER & CHANNEL SELECT
TEST TONE
Speaker Level balance Adjustment
The test tone function is useful to adjust the relative volume between
speakers in DOLBY DIGITAL or DOLBY PRO LOGIC II mode.
Once the balance is set, you don’t have to change the balance as
long as the speakers aren’t moved.
1. Adjust the MASTER VOLUME to the normal listening level. (Half
of max. Volume is recommended)
2. Press the TEST TONE button (on the remote control) in DTS,
Dolby Digital or Dolby PRO LOGIC II mode.
The test tone is emitted from each speaker each time you press
“TEST TONE”.
CHANNEL SELECT
Balancing volume between speakers in 5.1 channel mode when
using the 5.1 analogue inputs.
As the Dolby Digital signal is decoded in the external source,
sometimes, you may have to balance volume between speakers due
to the location of speakers. In this case:
→L(FRONTLEFT)→R(FRONTRIGHT)→LS (SUR. LEFT)
←
SUB ← C (CENTER) ← RS (SUR. RIGHT)
3. Select a speaker by pressing the “TEST TONE” button and
adjust the level by pressing the MASTER VOLUME button.
The level of each speaker can be adjusted in 1 dB step from –10
dB to +10 dB.
4. When the setting is finished, press the TEST TONE button to
stop the test tone. (Note: You must keep press TEST TONE until
one complete cycle is finished.)

AVAILABLE SURROUND MODE
DOLBY DIGITAL MODE
SURROUND MODE
The surround modes create a “live” atmosphere such as that
experienced in movie theaters, discos, stadiums and concert halls.
Select the appropriate surround mode according to the program
source. (Note: Surround speakers are needed for DTS/DOLBY
DIGITAL Dolby Pro Logic II surround modes to function).
It is recommended to use a Center speaker when operating this
unit in DTS/DOLBY DIGITAL/Dolby Pro Logic II surround modes.
The
DOLBY DIGITAL button can be pressed when you are using either
an Optical or Coaxial cable as the input connection because these
cables transmit the required encoded digital data.
Manufactured under license from Dolby Laboratories. “Dolby”,
“Pro Logic” and the double-D symbol are trademarks of Dolby
Laboratories
The DOLBY PRO LOGIC and DTS buttons can be pressed when
you are operating in Analog Mode.
When a Dolby Digital format signal is input, the surround mode
automatically switches to the DOLBY DIGITAL mode.
The Dolby Digital surround format lets you enjoy up to 5.1 channels
of digital surround sound from a Dolby Digital program source. If
you connect a DVD player or an LD player equipped with a DOLBY
DIGITAL output to the DIGITAL (Dolby Digital)/DTS/PCM DIGITAL
IN jack (Optical or Coaxial digital IN) on your AV Receiver and play
DVD or laser discs with the Dolby Digital trademark, you will
experience exceptional sound quality, great spatial accuracy, and
improved dynamic range. This is because Dolby Digital delivers 5
totally discrete, full frequency audio channels (Front Left Right,
Center, Surround Left and Right), plus a "0.1" channel called LFE
(Low frequency-only effects channel).
Dolby Digital is a system developed by Dolby laboratories that
transmits 5.1 digital signals, The surround system developed for
movie theaters using this system is called “Dolby SR-D (Surround
Digital)”. Because each channel is completely independent, a
realistic sound field with a “three-dimensions” feel is achieved
which gives the sound a sense of distance, movement and relative
position, creating a real and powerful sense of presence. Some
Dolby Digital programs carry information that allow you to
compress the dynamic range of sound track, without degrading the
sound quality, for softer sound effects when watching movies late
at night.
DTS DIGITAL SURROUND MODE
This unit is provided with the following Surround modes allowing
you to enjoy 5.1 (or 6) discrete channels of high quality digital
audio from DTS program sources bearing the DTS trademark such
as discs, DVDs and compact discs, etc. DTS Digital Surround
delivers up to 6 channels of transparent audio (which means
identical to the original masters) and results in exceptional clarity
within a genuine 360 degree sound field. The term DTS is a
trademark of DTS Technology, LLC. Manufactured under license
from DTS Technology,, LLC. (Note: DTS program sources should
be played back in DTS mode).
"DTS", and “DTS Digital Surround” are trademarks of
