CONNECTIONS

Connecting your computer

Audio from your computer can be fed to this unit using any of the following connectors: USB, DIGITAL PC COAX IN, DIGITAL
PC OPT IN, or ANALOG PC IN. If you use all of these connectors for connection, you can select the connector(s) to use on
this unit’s front panel or the remote control.

Connecting to the USB port (1)

If your computer has a USB port, connect it to this unit’s
USB terminal using the supplied USB cable, as shown
below.
A single USB connection is all that’s required to listen to
audio from your computer on this unit, feed audio from an
external source connected to this unit to your computer,
and control this unit remotely from your computer, using
the supplied Application Software.
If your computer doesn’t have a USB port, you can still
connect it to this unit using the analog or digital input, but in
this case you cannot use this unit’s Application Software.

Note

Connect the USB cable when installing the USB driver software
on your computer. Refer to the section “INSTALLING USB
DRIVER AND APPLICA TION SOFTW ARE”.

Connecting to analog inputs (2)

Connect the analog audio outputs on your computer or a
PC sound card to this unit’s ANALOG PC IN.
Use a commercially available pin-plug connection cord for
connection, and be careful not to mix up the left and right
connections.

Connecting to digital inputs (3)

To play DVD-Video discs encoded with Dolby Digital or
DTS, your computer must have a DVD-ROM drive and
DVD-Video decoder board, which should be connected to
this unit via the DIGITAL PC COAX IN or DIGITAL PC OPT
IN.
Use a commercially available pin-plug cord for connecting
to the DIGITAL PC COAX IN, and use a commercially
available optical fiber cable for connecting to the DIGITAL
PC OPT IN.

Note

The DIGITAL PC OPT IN has priority over the DIGITAL PC
COAX IN, so if you connect to both inputs, the signal received at
the DIGITAL PC OPT IN is used.

Protective Caps

When connecting to an optical connector, remove its protective
cap first. When an optical connector is not being used, replace its
cap to prevent dust entering the connector.

Notes

● Connecting a turntable

A turntable cannot be connected to this unit directly. Use a
commercially available phono equalizer amplifier to connect a
turntable to this unit, or connect a turntable incorporated with a
phono equalizer amplifier.

● [AP-U70 only]

The REC OUT OUTPUT and DIGITAL OPT OUT can
be used at the same time since they output signals
independently.

Notes

● When playing an ordinary CD on this unit following

playback of a CD or an LD encoded with DTS, some
operations, such as resetting the input selector keys, may be
required.

● Even if connected to this unit with a digital connection, some

CD, LD, and DVD players may make this unit fail to decode
DTS or produce noise. This is because certain digital output
data processing by such a player results in DTS-encoded data
errors that cause playback failure although the same data
processing may cause only a slight change in volume or in
frequency response in normal digital sound.

● When an error occurs in the player’s digital output data

during playback of an LD or CD encoded with DTS,
playback may be disrupted. If this occurs, stop playback and
repower the player.

● When digital sound signals from the computer are played,

errors in WAVE signals, etc. may occur resulting in noise or a
playback failure.

● Use speakers whose impedance is 6Ω or more.

● Connect the left speaker to the left speaker connector on this

unit and the right speaker to the right speaker connector.

● Make sure that the + and – polarity markings of the speaker

cables are observed and set correctly. If these cables are
reversed, the sound will be unnatural and lack bass.

[DP-U50 only]

To reproduce sound signals inputted to this unit over
speakers, connect this unit to speakers with a built-in
amplifier, a mini-component system, etc., or connect this
unit to speakers by using an external power amplifier.
Connect the analog inputs of speakers with a built-in
amplifier, etc. to this unit’s PRE OUT using a commercially
available analog pin-plug cord or a pin (stereo)-to-mini
(stereo) plug cord.

CONNECTIONS

Note

The level of signals outputted from the PRE OUT varies by the
use of the volume control on the front panel or the VOLUME
keys on the remote control. So, it is recommended to adjust the
speaker output level on this unit or the remote control, and fix
the volume of speakers with a built-in amplifier, etc. at a
certain level.

Recommended Speaker Placement

For best performance, place the left and right speakers on
either side of your computer monitor, as shown below, and
position them so that their fronts are flush with the monitor
screen. To get the best from the sound field programs and
surround effects, the left and right speakers and the
listener should be positioned so as to form a triangle with a
3:4 ratio, so if, for example, the speakers are 60 cm (23.5”)
apart, the listener should be 80 cm (31.5”) away from each
speaker.
If your system includes a subwoofer (YST-SW45, etc.),
place it on the floor.
