8 Surround Mode Selector: Press this button
to select from among the available surround mode
options for the mode group selected. The specific
modes will vary based on the number of speakers
available, the mode group and if the input source is
digital or analog. For example, press the Surround
Mode Group Selector 7 to select a mode grouping
such as Dolby or Logic 7, and then press this button
to see the available mode choices. For more informa-
tion on mode selection, see pages 22 and 23.
9 Tuning Selector: Press the left side of the button
to tune lower-frequency stations and the right side of
the button to tune higher-frequency stations. When the
tuner is in the MANUAL mode, each tap will increase
or decrease the frequency by one increment. When
the tuner receives a strong enough signal for adequate
reception, MANUAL TUNED will appear in the
Lower Display Line ¯ . When the tuner is in the
AUTO mode, press the button once, and the tuner will
scan for a station with acceptable signal strength.
When the next station with a strong signal is tuned,
the scan will stop and the Lower Display Line
will indicate AUTO TUNED. When an FM Stereo
station is tuned, the display will read AUTO ST
TUNED.
To switch back and forth between the Auto and
Manual tuning modes, press the Tuner Mode
Selector &.

* Optical 3 Digital Input: Connect the optical digital
audio output of an audio or video product to this jack.
¯
When the input is not in use, be certain to keep the
plastic cap installed to avoid dust contamination that
might degrade future performance.
( Coaxial 3 Digital Input: This jack is used for
connection to the output of portable audio devices,
video game consoles or other products that have a
coax digital audio jack.
Ó Bass Control: Turn this control to modify the low-
frequency output of the left/right channels by as much as
±10dB, when the unit is in the "Surround Off" mode.
Ô Video 3 Video Input Jacks: These jacks may be
used for temporary connection to the composite or S-
Video output of video games, camcorders or other
portable video products. You may make a connection
to either jack at any time, but not both simultaneously.
 Video 3 Audio Input Jacks: These audio jacks
may be used for temporary connection to video
games or portable audio/video products such as cam-
corders and portable audio players.
Ò Balance Control: Turn this control to change the
relative volume for the front left/right channels.
NOTE: For proper operation of the surround modes
this control should be at the midpoint or "12 o'clock"
position.
Ú Treble Control: Turn this control to modify the high
frequency output of the left/right channels by as much as
±10dB, when the unit is in the "Surround Off" mode.

Û Channel Adjust Selector: Press this button to
begin the process of trimming the channel output lev-
els using an external audio source. (For more informa-
tion on output level trim adjustment, see page 26.)
Ù Volume Control: Turn this knob clockwise to
increase the volume, counterclockwise to decrease
the volume. If the AVR 130 is muted, adjusting the
Volume Control Ù

will automatically release
the unit from the silenced condition.
ı Input Indicators: The name of the selected input
will appear here.
ˆ Speaker/Channel Input Indicators: These indi-
cators are multipurpose, indicating both the speaker
type selected for each channel and the incoming data-
signal configuration. The left, center, right, right surround
and left surround speaker indicators are composed of
three boxes, while the subwoofer is a single box. The
center box lights when a "small" speaker is selected,
and the two outer boxes light when "large" speakers are
selected. When none of the boxes are lit for the center,
surround or subwoofer channels, no speaker has been
assigned that position. (See page 16 for more informa-
tion on configuring speakers.) The letters inside each
box display the active input channels. For standard ana-
log inputs, only the L and R will light, indicating a stereo
input. For a digital source, the indicators will light to dis-
play the channels being received at the digital input.
When the letters flash, the digital input has been inter-
rupted. (See pages 18–19 for more information on the
Channel Indicators.)
˜ Upper Display Line: Depending on the unit's sta-
tus, a variety of messages will appear here. In normal
operation, this line will show the current input source
and which analog or digital input is in use. When the
tuner is the input, this line will identify the station as AM
or FM and show the frequency and preset number, if
any.
¯ Lower Display Line: Depending on the unit's sta-
tus, a variety of messages will appear here. In normal
operation, the current surround mode will show here.
˘ Surround Mode Indicators: The name of the
selected surround mode will appear here.
¸ Remote Sensor Window: The sensor behind
this window receives infrared signals from the remote
control. Aim the remote at this area and do not block
or cover it.
