further.

On power sources

• Before operating the receiver, 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 receiver.

• The receiver is not disconnected from

the AC power source (MAINS) as

long as it is connected to the wall

outlet, even if the receiver itself has

been turned off.

• If you are not going to use the

receiver for a long time, be sure to

disconnect the receiver from the wall

outlet. To disconnect the AC power

cord, grasp the plug itself; never pull

the cord.

• Should the AC power cord need to be

changed, have it done at a qualified

service shop only.

On placement

• Place the receiver in a location with

adequate ventilation to prevent heat

build-up and prolong the life of the

receiver.

• Do not place the receiver 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

receiver.

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

Speaker System Hookups

Overview

This section describes how to connect your speakers to

the receiver. To enjoy surround effects, centre and rear

speakers and an active woofer are required. For

specific locations of the terminals, see the illustration

below:

What cords will I need?

Speaker cord (not supplied) (1 for each speaker)

Twist the stripped ends of the cord about 2/3 inch (15 mm).

Be sure to match the speaker cord to the appropriate

terminal on the components: + to + and – to –. If the cords

are reversed, the sound will be distorted and will lack bass.

Getting Started

After connecting all the components, speakers, and AC

power cord, output a test tone to check that all the

speakers are connected correctly. For details on

outputting a test tone, refer to “Adjusting the speaker

volume” on page 10.

If you have connected rear speakers, be sure to press

the 5.1 CH/DVD button and turn off sound field on

the receiver before outputting a test tone so that the

tone is output individually from the left and right rear

speakers.

If no sound is heard from a speaker while outputting a

test tone or a test tone is output from a speaker other

than the one whose name is currently displayed on the

receiver, the speakers may be short-circuited. If this

happens, check the speaker connection again.

Active woofer

* STR-V525 only STR-V424 only

* You can connect the active woofer to either of the two

jacks. The remaining jack can be used to connect a second

active woofer.

Note

Do not connect any other component.

If you have an additional front speaker system

Connect them to the SPEAKERS FRONT B terminals.

If your TV monitor uses separate speakers

You can connect one of them to the SPEAKERS

CENTER terminals for use with Dolby Pro Logic

Surround sound (see page 10).

Where do I go next?

To complete your system, go to “AC Hookups” on page 9.

Selecting the impedance

Set the IMPEDANCE SELECTOR for the front speakers

as indicated in the table below. Check the instruction

manual of your speakers if you’re not sure of the

impedance. (This information is usually printed on a

label on the back of the speaker.)

Note

Be sure to connect the front speakers with nominal

impedance of 8 ohms or higher if you want to select both

sets of front speakers (see page 12).

Rear and center speakers

To avoid short-circuiting the speakers

Short-circuiting of the speakers may damage the

receiver. To prevent this, make sure to take the

following precautions when connecting the speakers.

Make sure the stripped ends of each speaker cord does

not touch another speaker terminal or the stripped end

of another speaker cord.

Examples of poor conditions of the speaker cord:

Stripped speaker cord is touching another speaker

terminal

Stripped cords are touching each other due to excessive

removal of insulation.

your speaker is

AC Hookups

Connecting the mains lead

Connect the mains lead cord from this receiver and

from your audio/video components to a wall outlet.

If you connect other audio components to the

SWITCHED AC OUTLET on the receiver, the receiver

can supply power to the connected components so you

can turn on/off the whole system when you turn on/

off the receiver.

Caution

Make sure that the power consumption of the component

connected to the receiver’s AC outlet does not exceed 100

watts. Do not connect high-wattage electrical home

appliances such as electric irons, fans, or TVs to this outlet.

Where do I go next?

Before you use the receiver, go to the next section to make

sure that all the controls are set to the appropriate positions.

3Use + or – to select the centre mode you want.

A description of each centre mode is as follows:

Adjusting the speaker volume

The test tone feature lets you set the volume of your

rear speakers and/or centre speaker to the same level

as that of the front speakers to maximize the Dolby Pro

Logic Surround effect. (If all of your speakers are equal

in performance, you don't have to adjust the speaker

volume.)

Using the controls on the remote, you can adjust the

volume level from wherever you're listening.

1Make sure that the centre mode is correctly set

(see the table on this page).

2Press SOUND FIELD ON/OFF to turn on the

sound field.

3Press SOUND FIELD MODE +/– repeatedly to

select “PRO LOGIC.”

4Press TEST TONE on the supplied remote.

Dolby Surround Setup

Dolby Pro Logic Surround is a system for decoding

Dolby Surround sound that is standardized for TV

programmes and movies. By selecting the proper

centre mode and adjusting the speaker volume, you

can reproduce highly precise localization and dynamic

panning of sounds of Dolby Surround encoded

software.

To obtain the best possible surround effect, you will

require at least one additional pair of speakers and/or

a centre speaker.

Locating the speakers

For optimum Dolby Pro Logic Surround sound, locate

your speakers as shown below.

Selecting the centre mode

The receiver offers you four centre modes:

PHANTOM, 3 STEREO, NORMAL, and WIDE. Each

mode is designed for a different speaker configuration.

Select the mode that best suits the speakers you use.
