OPERATION
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 125 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 ·c or the front-panel
Optical or Coaxial Digital Inputs #$.
To listen to a PCM digital source, first select the input for
the desired source (e.g., CD). Next, press the
Digital
Input Selector
Úp and then use the
⁄
/
¤
Buttons mq on the remote, or the Selector
Buttons
5 on the front panel, until the desired choice
appears in the
Main Information Display F.
When a PCM source is playing, the
PCM Indicator
A will light. During PCM playback, you may select
any surround mode except Dolby Digital or DTS.
If a 96kHz/24-bit PCM signal is detected, the name
of the current source input followed by
96K, for
example,
DVD/96K, will be displayed in the
Main Information Display F.You may select the
Stereo-Digital (Surround Off) mode to process this
type of signal.
Playback from PCM sources may also benefit from the
Logic 7 Mode. When playing back a surround-encoded
PCM source, such as an LD or surround-encoded CD,
use the Logic 7 C or Cinema mode. When playing
true stereo recordings, use the Logic 7 M or Music
mode for a wider soundstage and increased rear-
channel ambience.
NOTE: When a Logic 7 mode is in use with a Dolby
Digital 2.0 digital input source, that mode, rather than
Logic 7, will be used by the AVR after the digital bit-
stream is interrupted for any reason such as stopping
or pausing the digital playback. Note, also, that Logic 7
is not available with digital playback unless a two-
channel bitstream is in use.
Tuner Operation
The AVR 125’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 AM/FM
Band Selector
9.
2. Press the
AM/FM Tuner Select Button g or
AM/FM Band Selector 9 again to switch
between AM and FM so that the desired frequency
band is selected.
3. Press the
Tuning Mode Button
@
s to select
manual or automatic tuning.
In automatic tuning mode, the
AUTO Indicator R
is illuminated in the Main Information Display Û
and the tuner will stop only at those stations that
have a signal strong enough to be received with
acceptable quality.
When the
AUTO Indicator R is not illuminated,
the tuner is in a manual mode and will stop at each
frequency increment in the selected band.
4. To select stations, press the
Tuning Selector
Button
8
u.When the AUTO Indicator R is
illuminated, press the button and then release to
cause the tuner to search for the next highest- or
lowest-frequency station that has an acceptable
signal. When tuning FM stations in the Auto mode,
the tuner will select only stereo stations. To tune to
the next station, press the button again. If the
Stereo Indicator P is not illuminated, press the
Tuning Mode Button
@
s to activate the
manual mode, and tap the
Tuning Selector
Button
8
u to advance one frequency incre-
ment at a time, or press and hold it to locate a spe-
cific station. When the
TUNED Indicator Q lights,
the station is properly tuned and should be heard
with clarity.
5. Stations may also be tuned directly in either auto-
matic or manual tuning mode by pressing the
Direct Button t, and then pressing the
Numeric Keys
r
that correspond to the sta-
tion’s frequency. The desired station will automati-
cally be tuned. 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
Tuning Mode Button
@
s
until the Stereo Indicator P goes out. This will also
activate manual tuning mode.
Preset Tuning
Using the remote, up to 30 stations may be stored in
the AVR 125’s memory for easy recall using the front
panel controls or the remote.
To enter a station into the memory, first tune the sta-
tion using the steps outlined above. Then:
1. Press the
Memory Button on the remote.
Note that the
Memory Indicator O will be
illuminated and flash in the
Main Information
Display
Û.
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
Preset
Number/Sleep Time Display
J.
3. Repeat the process after tuning any additional sta-
tions 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.
• To manually tune through the list of stored preset
stations one by one, press the
Preset Stations
Selector Buttons
)z on the front panel or
remote.
Tape Recording
In normal operation, the audio or video source
selected for listening through the AVR 125 is sent to
the record outputs. This means that any program you
are watching or listening to may be recorded simply
by placing machines connected to the outputs for
Tape Outputs ¢ or Video 1 Outputs bk in
the Record mode.
When a digital audio recorder is connected to the
Optical fi or Coaxial fl Digital Audio Outputs,
you may record the digital signal using a CD-R,
MiniDisc or other digital recording system.
NOTES ON RECORDING:
• The AVR 125 converts analog inputs to a PCM
digital signal, enabling you to record the material
on a CD or MD recorder connected to
one of the
AVR 125’s
Digital Audio Outputs fifl.
The digital
recorder must be compatible with the output signal.
For example, the PCM digital input from a CD player
may be recorded on a CD-R or MiniDisc, but Dolby
Digital or DTS signals may not.
• Please make certain that you are aware of any
copyright restrictions on any material you copy.
Unauthorized duplication of copyrighted materials is
prohibited by federal law.
Output Level Trim Adjustment
Normal output level adjustment for the AVR 125 is
established using the test tone, as outlined on pages
18 and 19. In some cases, however, it may be desir-
able to adjust the output levels using program material
such as a test disc, or a selection you are familiar with.
