Battery installation

Since the remote control will be used for many of this unit’s control operations, you should begin by installing the

supplied batteries.

Turn the remote control over and remove the battery compartment cover by sliding it in the direction of the arrow.

Insert the batteries (AA, R6, UM-3 type) according to the polarity markings on the inside of the battery compartment.

Close the battery compartment cover.

Battery replacement

If you notice that the remote control must be used closer to the main unit, the batteries are weak. Replace both batteries with new ones.

Notes

● Use AA, R6, UM-3 batteries.

● Be sure the polarities are correct. (See the illustration inside

the battery compartment.)

● Remove the batteries if the remote control is not to be used for an extended period of time.

● If the batteries leak, dispose of them immediately. Avoid touching the leaked material and avoid contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries.

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.

➀

[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.
