What the UX-J51 Can Do

Various recording formats

Disc Playback

As well as music CDs, the system will also play discs containing recorded audio files (MP3/

WMA).

High-quality sound reproduction of iPod music

iPod Playback Function

With this system, the amplifier receives digital signals of iPod music as input. This

realizes the reproduction of high-quality sound minimizing the deterioration of sound

quality.

Supports for USB connection, analog input and digital input

External Input

The system supports the playback of a USB flash memory and USB mass storage class

compliant digital audio player. In addition, as well as analog input terminals for cassette

decks, the UX-J51 also features a sampling rate converter compliant digital input

terminal for digital tuners etc.

Choose your favorite audio quality

Digital Signal Processor Function

This includes “TONE”, which you can use to select detailed audio characteristics for the

low-, mid- and high-range bands, as well as “D-BASS” which allows you to adjust super-

bass effect.

Always install the system on a flat, stable surface. When installing the system on a stand of some sort, be

sure to check the strength of the stand.

The magnets used in the speakers may cause color irregularities on TV or PC screens. Do not set up the

speakers too close to a TV or PC.

l

Notes on installing the system

The sound will vary depending on the positioning of the speakers. To get the best possible sound quality,

note the guidelines below.

Ensure that the areas around the left and right speakers are as identical as possible. Set up the left

and right speakers away from the wall and hang thick curtains on any windows to minimize echoes or

reverberation.

Place the left and right speakers as far apart as possible.

Position the speakers at the same height as your ears when you are using the system.

l

Getting the best acoustic effect

Observe the following cautions when installing the system. Insufficient heat

radiation may build up internal heat and cause a malfunction or fire hazard.

Do not place any object on the system that may hinder heat radiation.

Do not place the system upside-down or lay it on its side.

Do not cover the system with a cloth or place it on a carpet or blanket.

Do not place the system in a narrow space that hinders the ventilation.

Leave the spaces specified below around the cabinets of the main unit.

Top panel: 50 cm (19-11/16 in.) or more

Side panel: 10 cm (3-15/16 in.) or more

Back panel: 10 cm (3-15/16 in.) or more

Install the system so the power outlet is easily accessible, and unplug the power

cord from the power outlet immediately in case of any trouble.

Note that the power supply to the system is not shut down completely by simply

setting the power switch to OFF.

To shut down the power supply completely, unplug the power cord.

l

Caution for

Connection

Do not plug the AC power cord into an AC wall outlet until all the connections are

completed. Before disconnecting any cords or cables, always turn the system off and

unplug the power cord from AC wall outlet.

Caution for outdoor antenna

installation

Since antenna installation requires skill and experience, always

consult your dealer before installation. The antenna should be

located away from power lines. If the antenna falls over, contact

with a power line creates the risk of electric shock.

The speakers are

not distinguished as

either the left or right

speaker.

Directly point to the

location and direction

that give the best

reception.

Connecting the System

The antenna supplied with the system is a basic antenna for indoor use. For stable signal

reception, the use of an outdoor antenna (commercially available) is recommended. To

connect an outdoor antenna, first remove the indoor antenna.

Connecting the FM indoor antenna

Preparing the ends of the speaker cords

Twist the plastic sleeve on the end of the cord as

you pull it off.

l

Notes on connecting the

speaker cords

Never short-circuit the positive (+) and negative (–) ends

of the speaker cords. (Do not touch the + and - cords

together.) Mistakenly reversing the positive and negative

polarity will result in unnatural sound and unclear sound.

Connecting the speakers

Microcomputer malfunctions

If the system is connected correctly and still does not

operate normally or shows display errors, reset the

microcomputer. (P.67)

The antenna supplied with the system is for indoor use. Place it as far as possible away from

the main unit, your TV set, the speaker cords and the power cord and point it in the direction

that gives the best reception.

Precautions when writing data to media

Discs recorded in Packet Write mode or UDF (Universal Disc Format) cannot be played.

When writing data to a disc, always close the session or finalize the disc. The disc may not play properly if

you do not close the session or finalize the disc.

Depending on the specifications of the writing software used, the recorded folder names and file names

may not be displayed correctly.

Playback for multi-session discs or discs that contain large numbers of folders may take longer to begin

than for normal discs.

If you write audio files and music CD tracks (CD-DA format) to the same disc, the disc may not play

correctly.

Before writing audio files to a disc, check that the files play back correctly on the PC being used to write the

files.

After you finish writing, check that the written files are played back correctly.

Use the correct file extensions (mp3, wma, m4a) in the names of audio files. Files without file extensions

will not play. Also, do not use audio file extensions (mp3, wma, m4a) for files that are not audio files.

For more information on file extensions, see <Supported Audio Files> on the right.

In this manual, MP3, WMA and AAC files are referred to collectively as “audio files”.
