The Super Audio CD includes high frequencies beyond
the audible range, although the design of normal
amplifiers and speakers is based on characteristics
corresponding to the audible range.
Therefore, if you increase the volume or treble excessively
during Super Audio CD playback, noise may occur or the
amplifier’s protect circuit may be activated. To prevent
these problems, set the switch at the rear of this player in
accordance with the connected amplifier.  This enables
you to match the output signal to the amplifier
characteristics.

This switch is set to “STANDARD” at the factory. When
you connect this player to a normal amplifier, leave the
switch as it is. Never set it to “CUSTOM,” otherwise noise
may be produced or the speakers and the amplifier may
be damaged.

When you connect this player to the Preamplifier TA-E1
(not supplied) and the Power Amplifier TA-N1 (not
supplied), remove the cover as illustrated below, and set
the switch to “CUSTOM.”
The “CUSTOM” mode enables you to enjoy wider range
of frequencies.

Note
When you record the audio signals of a Super Audio CD to a tape
deck (Cassette deck etc.), set the switch to “STANDARD” even if
the player is connected to the Preamplifier TA-E1 and the Power
Amplifier TA-N1.

Connect the supplied mains lead to the AC IN terminal on
the player.

Connect the supplied mains lead to the mains.

U.S.A. and Canadian models only
The supplied mains lead has a 3-pronged grounded plug.
If you are using 3-pronged grounded mains, the plug can
be inserted directly into the mains. However, if the socket
is a 2-pronged grounded mains, use the supplied plug
adapter or a commercially available plug adapter.

2-pronged polarized mains
• When the width of the mains are a different size

Use the supplied plug adapter.

• When the width of the mains are the same size

Use a commercially available plug adapter. In this case,
you can check the polarity of the mains with a
commercially available spark-testing screwdriver.  It is
the pronged ground that does not light the neon grow
lamp even if you insert the spark-testing screwdriver
into the mains. Insert the blades so that the “N pole”
can be inserted to the ground on the plug.

If noise (hum) is produced
Noise may be caused by an electric potential difference on
the ground circuit.* In this case, use the supplied plug
adapter and be careful not to connect the ground lead to
anything.

* Although the ground of the domestic mains is normally a

safety ground, a few electrical potential differences may be
produced, depending on the mains. Therefore, use of the
supplied 3-pronged mains lead may lessen the quality of the
audio signal or may produce humming noise.

When you connect this player to the following units,
remove the cover as illustrated below, then set the switch
to “CUSTOM.”
• TA-E1 (stereo preamplifier) and TA-N1 (stereo power

amplifier)

• T A-FA777ES (integrated stereo amplifier)
The “CUSTOM” mode enables you to enjoy a wider range
of frequencies.

Note
When you record the audio signals of a Super Audio CD to a tape
deck (Cassette deck etc.), set the switch to “STANDARD” even if
the player is connected to the one of the units described above.

You can play the following discs with this player.
Depending on the type of disc to be played, select the
appropriate indicator by pressing SACD/CD (pages 8,
12).

This disc consists of a single HD layer*.
Press SACD/CD repeatedly so that the SACD indicator
on the upper side of the player lights.
*High density signal layer for the Super Audio CD

This disc consists of dual HD layers and is capable of
extended play over long periods.
Press SACD/CD repeatedly so that the SACD indicator
on the upper side of the player lights.
Also, as the dual layer disc consists of dual HD layers on
one side only, it is not necessary to turn the disc over.

This disc is the current format.
Press SACD/CD repeatedly so that the CD indicator on
the upper side of the player lights.

This disc consists of an HD layer and a CD layer. Press
SACD/CD to select the layer you want to listen to. Also,
as the dual layers are on one side, it is not necessary to
turn the disc over. You can play the CD layer using a
conventional CD player.

Incompatible Discs
This player cannot play the following discs. If you try to
play them, the error message “TOC Error” will appear or
there will be no sound.
• CD-ROM
• DVD etc.
