* 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 Video 4 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 to both simultaneously.
Ô Video 4 Audio Input Jacks: These audio jacks
may be used for temporary connection to video
games or portable audio/video products such as
camcorders and portable audio players.
Bass Control: Turn this control to modify the low-
frequency output of the left/right channels by as much
as ±10dB.
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.
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 29.)
Ù Volume Control: Turn this knob clockwise to
increase the volume, counterclockwise to decrease the
volume. If the AVR 230 is muted, adjusting the
Volume Control Ù will automatically release
the unit from the silenced condition.
ı Input Indicators: The current selected source will
appear as one of these indicators. Note that when the
unit is turned on, the entire list of available modes will
light briefly, and then revert to normal operation with
only the active mode indicator illuminated.
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 18 for more informa-
tion on configuring speakers.) The letters inside each
box displays the active input channels. For standard
analog inputs, only the L and R will light, indicating a
stereo input. For a digital source, the indicators will light
to display the channels being received at the digital
input. When the letters flash, the digital input has been
interrupted. (See page 27 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 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 current selected
surround mode will appear as one of these indicators.
Note that when the unit is turned on, the entire list of
available modes will light briefly, and then revert to
normal operation with only the active mode indicator
illuminated.
¸ 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.
