Getting Started

WARNING

To prevent fire or shock hazard, do not expose the unit to rain or moisture.

IMPORTANT: never connect two mains leads into a single mains plug.

To avoid electrical shock, do not open the cabinet. Refer servicing to qualified personnel only.

Do not install the appliance in a confined space, such as a bookcase or built in cabinet.

If the power switch is kept depressed, you can turn on and off the components by only pressing the SYSTEM POWER switch on the remote.

-For CDP-CX571/ST-JX661/TC-WR661-

The mains lead plug of CDP-CX571/ ST-JX661/TC-WR661 is a 2-pin type designed to be connected only to TA-AV561A.

Do not connect this plug to any other system or mains supply.

Precautions

On safety

•Should any solid object or liquid fall into the cabinet, unplug the amplifier and have it checked by qualified personnel before operating it any further.

•Because the amplifer emits heat during operation, do not place any other components on top of this unit.

On power sources

•Before operating the amplifier, check that the operating voltage is identical with your local power supply. The operating voltage is indicated on the nameplate at the rear of the amplifier.

•This unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off.

•If you are not going to use the amplifier for a long time, be sure to disconnect the amplifier from the wall outlet. To disconnect the mains lead, grasp the plug itself; never pull the cord.

•The AC power cord must be changed only at the qualified service shop.

•The mains switch is located on the front exterior.

On placement

•Place the amplifier in a location with adequate ventilation to prevent heat build-up and prolong the life of the amplifier.

•Do not place the amplifier near heat sources, or in a place subject to direct sunlight, excessive dust or mechanical shock.

•Do not place anything on top of the cabinet that might block the ventilation holes and cause malfunctions.

On operation

•Before connecting other components, be sure to turn off and unplug the amplifier.

On cleaning

•Clean the cabinet, panel and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine.

If you have any question or problem concerning your amplifier, please consult your nearest Sony dealer.

Getting Started

Unpacking

Check that you received the following items with the amplifier:

•Remote controller (remote) (1)

•Size AA (R6) batteries (2)

Inserting batteries into the remote

Insert two size AA (R6) batteries in accordance with the + and – marking on the battery compartment. When using the remote, point it at the remote sensor g on the amplifier.

When to replace batteries

Under normal use, the batteries should last for about 6 months. When the remote no longer operates the amplifier, replace both batteries with new ones.

Notes

•Do not leave the remote in an extremely hot or humid place.

•Do not use a new battery with an old one.

•Do not expose the remote sensor to direct sunlight or lighting apparatuses. Doing so may cause a malfunction.

•If you don’t use the remote for an extended period of time, remove the batteries to avoid possible damage from battery leakage and corrosion.

Hookup Overview

The amplifier allows you to connect and control the following audio/video components. Follow the hookup procedures on the specified pages for the components that you want to connect to the amplifier. To learn the locations and names of each jacks, see “Rear Panel Descriptions” on page 18.

220-240 V

Connecting the mains lead

Connect the mains lead from CDP-CX571/ST-JX661/ TC-WR661 to the SWITCHED AC OUTLETs on this amplifier. Then, connect the mains lead from this amplifier to wall outlet.

Connecting other components to the SWITCHED AC OUTLETs on the amplifier, enables the amplifier to supply power to the connected components so you can turn on/off whole system when you turn on/off the amplifier.

SWITCHED AC OUTLETs

Centre mode

Setting of speakers to enhance Dolby Pro Logic Surround mode. To obtain the best possible surround sound, select one of the following four centre modes according to your speaker system.

•NORMAL mode

Select NORMAL mode if you have front and rear speakers and a small centre speaker. Since a small speaker cannot produce enough bass, the bass sound of the centre channel is output from the front speakers.

Front				Centre						Front
			speaker

Select PHANTOM mode if you have front and rear speakers but no centre speaker. The sound of the centre channel is output from the front speakers.

Front					Front

Rear	Rear
speaker (L)	speaker (R)

Delay time

Time lag between the surround sound output from front speakers and rear speakers. By adjusting the delay time of the rear speakers, you can obtain the feeling of presence. Make the delay time longer when you have placed the rear speakers in a small room or close to your listening position, and make it shorter when you have placed them in a large room or apart from your listening position.

Dolby Pro Logic Surround

Decoding system of Dolby Surround sound standardized in TV programmes and movies. Compared with the former Dolby Surround system, Dolby Pro Logic Surround improves sound image by using four separate channels: off-screen audio effects, on-screen dialog, left-to-right panning, and music. These channels manipulate the sound to be heard and enhance the action as it happens on the screen. To take advantage of Dolby Pro Logic, you should have at least one pair of rear speakers and/or one centre speaker. You also need to select the appropriate centre mode to enjoy a full effect.

Dolby Surround

Encoding and decoding system of Dolby Surround sound for consumer use. Dolby Surround decodes the extra channels on the Dolby Surround-encoded sound tracks of movie videos and TV programmes and produces sound effects and echoes that make the action seem to envelop you.

The amplifier offers Dolby Surround as one of the pre-programmed sound fields. If you have rear or centre speaker(s), we recommend that you customize the Dolby Surround sound field by selecting the appropriate centre mode to take advantage of Dolby Pro Logic Surround sound.

Parameter

Variable of sound that composes sound image, such as tone or delay time. You can customize the pre-programmed sound fields by adjusting parameters to suit your listening situation.

Sound field

Sound pattern produced by a sounding source or sources in a given environment due to direct and reflected sounds and the acoustics of the environment. The amplifier offers 5 pre-programmed sound fields (ROCK, POPS, CLASSIC, MOVIE and GAME) to let you enjoy surround sound easily.

Surround sound

Sound that consists of three elements: direct sound, early reflected sound (early reflections) and reverberative sound (reverberation). The acoustics where you hear the sound affect the way these three sound elements are heard. These sound elements are combined in such a way that you can actually feel the size and the type of a concert hall.
