The Night Mode may be engaged when a Dolby Digital DVD is playing by pressing the
Night
Mode Button [oval 34] on the remote. Next, press the ▼ / ▲ Navigation Button [oval 16] to
select either the middle range or full compression versions of the Night mode. To turn the Night
mode off, press the
▼ / ▲ Navigation Button [oval 16] until the message in the lower third of the
video display and in the AVR Lower Display Line [square 34] reads NIGHT MODE OFF.
The Night Mode may also be selected to always be on at either level of compression using the
options in the
SOURCES 1 SETUP menu. See Audio Mode/Dolby for information on using the
menus to set this option.
MP3 Audio Playback
The AVR21EN is one of the few receivers equipped for onboard decoding for the MP3 audio
format used by computers and portable audio devices. By offering MP3 decoding, the AVR21EN
is able to deliver precise conversion of the digital signals to an analog output, along with the
benefits of listening to the MP3 audio through the AVR21EN’s high-power amplifier and the
speakers from your surround system, rather than the smaller speakers and low-powered
amplifiers typically used with computers.
To take advantage of the AVR21EN’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 [circles 19, 24] or the front-panel Digital Inputs [squares 13, 16] . When
the digital signal is available, the AVR Lower Display Line [square 34] will indicate that an MP3
bitstream is present, and the audio will begin playing.
NOTES:
• The AVR21EN is only capable of playing signals in the MP3 (MPEG 1/Layer 3) format. It is not
compatible 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.
• If your computer or sound card’s digital output is not capable of direct connection to the
AVR21EN, you may use an optional, external transcoder to convert the USB output of a
computer to a format compatible with the AVR.
• Due to the wide variation in MP3 formats and encoding speeds, it is possible that the AVR21EN
may not be compatible with all MP3 input signals. Some may produce unacceptable results or
may not be decoded. This is not a fault of either the computer or the AVR21EN, but rather a by-
product of the unpredictable nature of MP3 playback.
• Even when your computer does not have a digital output that is compatible with the AVR21EN,
you may connect the analog audio output available on virtually all computers to one of the
AVR’s analog audio inputs using an optional adaptor cable that converts the stereo mini plug
commonly used for computer audio connections to the left/right RCA jacks used on the AVR.
Connecting your computer to the AVR will enable you to take advantage of the high-quality
audio reproduction possible with a home theater system, as well as enable the use of surround
processing modes such as Logic 7, to greatly enhance downloaded or streaming audio
playback.
IMPORTANT NOTES ON DIGITAL PLAYBACK:
• When the digital playback source is stopped, or in a pause, fast forward or search mode, digital
audio data will momentarily stop, and the channel position letters inside the AVR
Speaker/Channel Input Indicators [square 35] will flash and an UNLOCK message may
