Preparations
Make connections as shown on the following pages.
When connecting the related system components, be sure
to also refer to the instruction manuals supplied with the
components you are connecting.
Do not connect the power cord to a wall outlet until all
connections are completed.
Notes
1. Be sure to insert all connection cords securely. If their connections are
imperfect, the sound may not be produced or noise may interfere.
2. Be sure to remove the power cord from the AC outlet before plugging or
unplugging any connection cords. Plugging/unplugging connection cords
without disconnecting the power cord can cause malfunctions and may
damage the unit.
3. Do not connect power cords from components which power consump-
tion is larger than what is indicated on the AC outlet at the rear of this unit.
Setting up the system
DTS Digital Surround™ is a discrete 5.1 channel digital audio format
available on CD, LD, and DVD software which consequently cannot be
decoded and played back inside most CD, LD, or DVD players. For this
reason, when DTS-encoded software is played back through the analog
outputs of the CD, LD, or DVD player, excessive noise will be exhibited.
To avoid possible damage to the audio system, proper precautions
should taken by the consumer if the analog outputs are connected
directly to an amplification system. To enjoy DTS Digital Surround™
playback, an external 5.1 channel DTS Digital Surround™ decoder
system must be connected to the digital output (S/P DIF, AES/EBU, or
TosLink) of the CD, LD or DVD player.
DTS disclaimer clause
Analog connections
Audio connections are made using RCA pin cords. These cables transfer
stereo audio signal in an “analog” form. This means the audio signal
corresponds to the actual audio of two channels. These cables usually have
2 plugs on each end, one red for the right channel and one white for the left
channel. These cables are usually packaged with the source unit, or are
available at your local electronics retailer.
Microcomputer malfunction
If operation is not possible or an erroneous display appears, even though
all connections have been made properly, reset the microcomputer
referring to “In case of difficulty”. y
Be sure to adhere the followings. Or proper ventilation will be blocked
causing damage or fire hazard.
• Do not place any objects impairing heat radiation onto the top of unit.
CAUTION
INPUT SELECTOR
INPUT MODE
Input mode settings
CD/DVD, DVD/6ch, VIDEO2 and VIDEO3 inputs each include jacks for
digital audio input and analog audio input.
You must select beforehand which type of input is to be used for each
connected component.
The initial factory settings for audio signal playback (CD/DVD,
DVD/6ch) and (VIDEO2, VIDEO3) are digital and analog respec-
tively.
To use the analog audio input for playback instead (if, for example, you
have connected a VCR to the VIDEO2 or VIDEO3 input), you must set
the input mode for the corresponding input to the analog mode.
After completing connections and turning on the receiver, follow the
steps below.
1 Use the INPUT SELECTOR knob to select CD/DVD, DVD/6ch,
VIDEO2, or VIDEO3.
2 Press the INPUT MODE key.
Each press switches the setting as follows:
In DTS play mode
1 D-AUTO (digital input, auto sound)
2 D-MANUAL (digital input, manual sound)
In DVD/6ch play mode
1 D-AUTO (digital input, auto sound)
2 D-MANUAL (digital input, manual sound)
3 6ch INPT (DVD/6ch input)
4 ANALOG (analog input, manual sound)
In modes other than DTS or DVD/6ch play mode
1 D-AUTO (digital input, auto sound)
2 D-MANUAL (digital input, manual sound)
3 ANALOG (analog input, manual sound)
Digital input:
Select this setting to play digital signals from a DVD, CD, or LD player.
Analog input:
Select this setting to play analog signals from a cassette deck, VCR,
or turntable.
Auto sound:
In the auto sound mode (AUTO SOUND indicator lights), the receiver
selects the listening mode automatically during playback to match the
type of input signal (Dolby Digital, PCM, DTS ) and the speaker setting.
The initial factory setting is auto sound on.
To keep the receiver set to the currently selected listening mode, use
the INPUT MODE key to select “D-MANUAL” (manual sound).
However, even when this setting is selected, there may be cases in
which the listening mode is selected automatically to match a Dolby
Digital source signal depending on the combination of listening mode
and source signal.
If the INPUT MODE key is pressed quickly, sound may not be
produced.
