MP3 Audio Playback

The AVR 7300 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 AVR 7300 is able to deliver pre-

cise conversion of the digital signals to an analog out-

put, along with the benefits of listening to the MP3

audio through the AVR 7300’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 AVR 7300’s MP3 capabili-

ties, simply connect the S/P-DIF output of a comput-

er’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

. 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 7300 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.

• If your computer or sound card’s digital output is not

capable of direct connection to the AVR 7300, 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 7300

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 AVR 7300, 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 AVR 7300, 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 Speaker/Channel Input

Indicators @ will flash and an UNLOCK mes-

sage may appear. This is normal and does not indi-

cate a problem with either the AVR 7300 or the

source machine. The AVR 7300 will return to digital

playback as soon as the data is available.

• Some source devices, particularly cable set-top

boxes, will switch back and forth between digital and

analog audio outputs, depending on the channel

being watched. To avoid losing sound with this type

of product, it is recommended that you connect

both the digital and analog audio outputs of the

source to the AVR 7300, with the digital audio input

set as the default following the steps shown on

page 23. The AVR will monitor the digital data

stream and when it is interrupted the sound will

mute briefly and possibly display an UNLOCK

message while it switches to the analog audio input.

This switching is not a fault of either the AVR or the

cable box, as it is caused by the use of different

audio technologies on different channels by the

cable company or program supplier.

• Although the AVR 7300 will decode virtually all current

DVD movies, CDs and HDTV sources,

it may not be

compatible with future digital sources

• 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, 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 π∆. However, the digital signals

will be passed through to the Digital Audio

Outputs œß .

Tuner Operation

The AVR 7300’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 sta-

tion presets and recalled from a 30-position memory.

Station Selection

1. Press the AM/FM 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 Button or Tuner Band

Selector 5 again to switch between AM and FM

so that the desired frequency band is selected.

3. Press the Tuner Mode Selector

l to select

manual or automatic tuning.

When the button is pressed so that AUTO or

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 acceptable 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 Selectors 4w again

to scan to the next station.

When the button is pressed so that MANUAL

or MANUAL/MONO appears in the Upper

Display Line #, each tap of the Tuning

Selectors 4w 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 Button .

Next, press the Direct Button i. Within five

seconds of when DIRECT IN scrolls in the

Upper Display Line #, enter the station fre-

quency by pressing the Numeric Keys k. If you

press an incorrect button while entering a direct fre-

quency, 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 Tuner Mode Button

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 7300’s memory for easy recall using the

front-panel controls or the remote.
