has been interrupted. This will happen when a digital
input source is selected before the playback starts, or
when a digital source such as a DVD is paused. The
flashing indicators remind you that the playback has
stopped due to the absence of a digital signal and not
through any fault of the AVR 230. This is normal, and
the digital playback will resume once the playback is
started again.
Night Mode
A special feature of Dolby Digital is the Night mode,
which enables specially encoded Dolby Digital input
sources to be played back with full digital intelligibility
while reducing the minimum peak level by 1/4 to 1/3.
This prevents abruptly loud transitions from disturbing
others, without reducing the impact of the digital
source. The Night mode is available only when Dolby
Digital signals with special data are being played.
The Night mode may be engaged when a Dolby
Digital DVD is playing by pressing the
Night Mode
Button
l on the remote. Next, press the
⁄
/
¤
Buttons n to select either the middle range or
full compression versions of the Night mode. To turn
the Night mode off, press the

until the message in the lower third of the video dis-
play and in the
Lower Display Line ¯ reads
D-RANGE OFF.
The Night mode may also be selected to always be on
at either level of compression using the options in the
DOLBY menu. See page 18 for information on
using the menus to set this option.
IMPORTANT NOTES ON DIGITAL PLAYBACK:
• When the digital playback source is stopped, or in
a pause, fast-forward or chapter-search mode, the
digital audio data will momentarily stop, and the
channel position letters inside the
Speaker/
Channel Input Indicators
ˆ will flash. This is
normal and does not indicate a problem with either
the AVR 230 or the source machine. The AVR 230
will return to digital playback as soon as the data is
available and when the machine is in a standard
play mode.
• Although the AVR 230 will decode virtually all current
DVD movies, CDs and HDTV sources, it is possible
that some future digital sources may not be compati-
ble with the AVR 230.
• Not all digitally encoded programs contain full 5.1-
or 6.1-channel audio. Consult the program guide
that accompanies the DVD or laser disc to deter-
mine which type of audio has been recorded on the
disc. The AVR 230 will automatically sense the type
of digital surround encoding used and adjust to
accommodate it.
• When some digital sources are playing, you may not
be able to select some of the analog surround
modes such as Dolby Pro Logic II, Dolby 3, Stereo,
Hall, Theater or Logic 7.
• When a Dolby Digital or DTS source is playing,
it is not possible to make an analog recording using
the
Tape Outputs £ and Video 1 or Video 2
Audio Outputs
. However, the digital signals
will be passed through to the
Digital Audio
Outputs
·a.
PCM Audio Playback
PCM (Pulse Code Modulation) is the noncompressed
digital audio system used for compact discs and laser
discs. The digital circuits in the AVR 230 are capable of
high-quality digital-to-analog decoding, and they may
be connected directly to the digital audio output of your
CD or LD player.
Connections may be made to either the rear-panel
Optical or Coaxial Inputs cf or the front-panel
Digital Inputs *(.
To listen to a PCM digital source, first select the input for
the desired source (e.g., CD). Next press the
Digital
Select Button
#q and then use the
⁄
/
¤
Buttons n on the remote, or the
‹

Selector
Buttons
) on the front panel, until the desired choice
appears in the
Upper Display Line ˜.
During PCM playback, you may select any Surround
mode except Dolby Digital or DTS.
Tuner Operation
The AVR 230’s tuner is capable of tuning AM, FM and
FM Stereo broadcast stations. Stations may be tuned
manually, or they may be stored as favorite station pre-
sets and recalled from a 30-position memory.
Station Selection
1. Press the AM/FM Tuner Select Button g on
the remote to select the tuner as an input. The
tuner may be selected from the front panel by
either pressing the
Input Source Selector ^
until the tuner is active or by pressing the Tuner
Band Selector
!.
2. Press the
AM/FM Tuner Select Button g or
Tuner Band Selector ! again to switch between
AM and FM so that the desired frequency band is
selected.
3. Press the
Tuner Mode Button
&
s to select
manual or automatic tuning.
When the button is pressed so that
AUTO
appears in the Lower Display Line ¯ each
press of the
Tuning Selectors 9u will put the
tuner in a scan mode that seeks the next higher or
lower frequency station with acceptable signal
strength. An
AUTO ST TUNED indication will
momentarily appear when the station stops at a
stereo FM station, and an
AUTO TUNED indi-
cation will momentarily appear when an AM or
monaural FM station is tuned. Press the Tuning but-
tons again to scan to the next receivable station.
When the button is pressed so that
MANUAL
appears in the Lower Display Line ¯ each tap
of the Selector will increased or decrease the fre-
quency by one increment. When the tuner receives
a strong enough signal for adequate reception,
MANUAL TUNED will appear in the Lower
Display Line
¯.
4. Stations may also be tuned directly in either the
automatic or manual mode. To enter a station’s fre-
quency directly, first select the AM or FM band as
desired be pressing the
AM/FM Tuner Select
Button
g. Next, press the Direct Button t.
Within five seconds of seeing the
DIRECT IN
scroll in the Upper Display Line ˜, enter the
station frequency by pressing the
Numeric Keys
r. If you press an incorrect button while entering
a direct frequency, press the
Clear Button to
start over.
NOTE: When the FM reception of a station is weak,
audio quality will be increased by switching to Mono
mode by pressing the
Tuner Mode Button
&
s
so that MANUAL appears momentarily in the
Lower Display Line ¯ goes out. This will also
activate manual tuning mode.
Preset Tuning
Using the remote, up to 30 stations may be stored in
the AVR 230’s memory for easy recall using the front
panel controls or the remote.
To enter a station into the memory, first tune the
station using the steps outlined above. Then:
1. Press the
Memory Button on the remote.
Two underscore lines will appear at the far right
side of the
Upper Display Line ˜.
2. Within five seconds, press the
Numeric Keys r
corresponding to the location where you wish to
store this station’s frequency. Once entered, the
preset number will appear in the
Upper Display
Line
˜.
3. Repeat the process after tuning any additional
stations to be preset.
Recalling Preset Stations
• To manually select a station previously entered in
the preset memory, press the
Numeric Keys r
that correspond to the desired station’s memory
location.
