OPERATION 37
To take advantage of the AVR 635’s MP3 capabilities,
simply connect the S/P-DIF output of a computer’s
sound card or the S/P-DIF output of a portable digital
audio device to either the rear panel
Digital Inputs
or the front-panel
Digital Inputs
KM
.
When the digital signal is available, the
Lower
Display Line
$
will indicate that an MP3 bitstream
is present, and the audio will begin playing.
NOTES:
• The AVR 635 is only capable of playing signals in
the MP3 (MPEG 1/Layer 3) format. It is not com-
patible with other computer audio codecs.
• The digital audio input signal may be either optical
or coaxial, but the signal must be in the S/P-DIF
format. Direct connection of USB or serial data
outputs is not possible, even though the signals
are in the MP3 format. If you have any questions
about the data output format from your computer
or a sound card, check with the device’s owner’s
manual or contact the manufacturer’s technical
support area.
• If your computer or sound card’s digital output is not
capable of direct connection to the AVR 635, you
may use an optional, external transcoder to convert
the USB output of a computer to a format compati-
ble with the AVR.
• Due to the wide variation in MP3 formats and
encoding speeds, it is possible that the AVR 635
may not be compatible with all MP3 input signals.
Some may produce unacceptable results and some
may not be decoded. This is not a fault of either the
computer or the AVR 635, but rather a by-product
of the unpredictable nature of MP3 playback.
IMPORTANT NOTES ON DIGITAL PLAYBACK:
• When playing DVDs, please note that even when you
have selected a specific digital audio format for play-
back, an individual disc may change formats or the
number of available channels during playback. For
example, even if you select a DTS mode for the movie,
you may see Dolby Digital in use when the trailers,
menus or copyright warnings are playing. This is not a
fault with either the AVR or your DVD player, as both
are responding to the way the disc was created.
• When viewing digital television signals, note that the
number of audio channels available may vary during
the course of a program, depending on the content.
For example, while a sports even may have 5.1
sound, the commercials or local station content may
be in 2.0. In addition, not all local stations are currently
equipped for carrying the 5.1 digital audio signals. This
may mean that even though the actual program is
produced with 5.1, it may be transmitted in a 2.0
configuration in some areas. Your AVR will automatically
change to react to the proper type of audio stream if it
is changed by the broadcast station.
• Although the AVR 635 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 635.
• 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 635 will automatically sense the type
of digital surround encoding used and adjust to
accommodate it.
• When a digital source is playing, you may not be
able to select some of the analog surround modes
such as Dolby Pro Logic II, Dolby Pro Logic IIx,
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
ik
M
.
Tuner Operation
The AVR 635’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 Selector Button
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
7
until the tuner is active or by pressing the
Tuner
Band Selector
5
.
2. Press the
AM/FM Tuner Select Button
or
Tuner Band Selector
5
again to switch between
AM and FM so that the desired frequency band is
selected.
3. Press the
Tuning Mode Selector
8 l
to select
manual or automatic tuning.
When the button is pressed so that
AUTO/
STEREO
appears in the
Upper Display Line
#
, each press of the
Tuning Selectors
4w
will put the tuner in a scan mode that seeks the
next higher or lower frequency station with accept-
able signal strength. An
AUTO ST TUNED
indication will momentarily appear when the
station stops at a stereo FM station, and an
AUTO TUNED
indication will momentarily
appear when an AM or monaural FM station is
tuned. Press the Tuning buttons again to scan to
the next receivable station.
When the button is pressed so that
MANUAL/
MONO
appears in the
Upper Display Line
#
,
each tap of the Selector 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
$
.
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
5
. Next, press the
Direct Button
i
. Within 5 seconds of when
DIRECT IN
scrolls in the
Upper Display Line
#
, enter the
station frequency by pressing the
Numeric Keys
k
. If you press an incorrect button while entering
a direct frequency, press the
Clear Button
j
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
8l
so that
MANUAL/MONO
appears momentarily
in the
Upper Display Line
#
and then goes out.
This will also activate manual tuning mode.
Preset Tuning
Using the remote, up to 30 stations may be stored in the
AVR 635’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; the
station’s frequency will flash.
2. Within five seconds, press the
Numeric Keys
k
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
k
that
correspond to the desired station’s memory
location.
• To manually tune through the list of stored preset sta-
tions one by one, press the
Preset Stations Selector
Buttons
6v
on the front panel or remote.
