AVR 260/230 Service Manual

Each precaution in this manual should be followed during servicing.

in the parts list are special significance to safety. When replacing a component identified with

, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the

parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably

insulated from the supply circuit before retuming the product to the customer.

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called

Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and

The following techniques should be used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on

your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,

which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to

prevent electrostatic charge build-up or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as 'anti-static' can generate electrical charges

5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement

ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the

chassis or circuit assembly into which the device will be installed.

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together

or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

volume control will automatically release the unit from the silenced
condition.

System Power Control: When the Main Power Switch on the rear

panel is “ON,” press this button to turn on the AVR; press it again to turn
the unit off (to Standby). Note that the Power Indicator 2 will turn
white when the unit is on.

Power Indicator: This LED will be illuminated in amber when the

unit is in the Standby mode to signal that the unit is ready to be turned
on. When the unit is in operation, the indicator will turn white.

Headphone Jack: This jack may be used to listen to the AVR’s

output through a pair of headphones. Be certain that the headphones
have a standard 6,3 mm stereo phone plug. Note that the speakers will
automatically be turned off when the headphones are connected.
When configuring your system using EzSet/EQ, the calibration
microphone should be plugged into this jack using the supplied adaptor
that converts the small mini-plug at the end of the microphone’s cord to
a 6,3 mm plug.

Info Settings Button: Press this button to directly access the

Setup Source submenu, which contains the settings for the current
source.

Resolution: Pressing this Button once and then using the

Buttons 4 changes the AVR’s video output resolution to these settings:
576i, 576p, 720p, 1080i or 1080p. The AVR is set to default to 576i when
first switched on, or if you reset it later. This resolution has been chosen
to ensure that the On Screen Display information is visible on your TV
even with analog S-Video or Composite (CVBS) signals. Having selected
the best resolution for your system, confirm with the

Audio Effects: Press this button to directly access the Audio Effects

submenu, which allows adjustment of the tone and other controls. See
the

section for more information.

Video Modes: Press this button for direct access to the Video Modes

submenu, which contains settings that may be used to improve the
picture if necessary after you have adjusted the picture settings using
the video display or TV.

Remote Sensor Window: The sensor behind this window receives

infrared signals from the remote control. Aim the remote at this area
and do not block or cover it unless an external remote sensor is installed.

Main Information Display: This display delivers messages and

status indications to help you operate the receiver.

Speaker/Channel Input Indicators: These indicators are

multipurpose, indicating either the speaker type selected for each
channel or the incoming data-signal configuration. The left, center,
right, right surround and left surround speaker indicators are composed
of three boxes, while the subwoofer is a single box. The center box lights
when a “Small” speaker is selected, and the two outer boxes light when
“Large” speakers are selected. When none of the boxes are lit for the
center, surround or subwoofer channels, no speaker has been selected
for that position. (See page 20 for more information on configuring
speakers.) The letters inside each of the center boxes display active
input channels. For standard analog inputs, only the L and R will light,
indicating a stereo input. When a digital source is playing, the indicators
will light to display the channels being received at the digital input.
When the letters flash, the digital input has been interrupted.
(See page 31 for more information on the Channel Indicators).

NOTE: When you have reassigned the surround back speakers to the
remote zone using the

menu, the boxes that indicate

the presence of the surround back speakers will automatically disappear,
reflecting the fact that the main listening area is now configured for
5.1-channel operation. (See page 33 for more information on reassigning
the surround back speakers for multiroom use.)

Surround Modes: Press this button to select a surround sound

(e.g.,multichannel) mode. The Surround Modes menu will appear on
screen, and the menu line will appear on the lower line of the front-
panel display.
Use the front-panel or remote

Buttons to highlight a different

menu line: Auto Select, Virtual Surround, Stereo, Movie, Music or Video
Game. Each line represents a type of audio signal, and is set to the
surround mode the AVR will automatically select when it detects the
audio signal.
You may manually select a different mode for each type of audio. Press
the

OK Button when the menu line is highlighted, and the available

surround mode options for the current signal will appear. Use the

Buttons to select the desired mode, and press the

it. Press the Back/Exit Button to exit the Surround Modes menu and
display the next higher menu in the hierarchy.
See the Advanced Functions section for more information on surround
modes.

Back/Exit: Press this button to return to the previous menu. When the

main AVR menu is displayed, press this button to exit the menu system.

Digital Optical Front Input: Connect the optical digital audio

Digital Coax Front Input: This jack is normally used for connection

to the output of portable digital audio devices, video game consoles or
other products that have a coax digital jack.

Video Front Input Jacks: These audio/video jacks may be used for

temporary connection to video games or portable audio/video products
such as camcorders and portable audio players.

Source List: Press this button to select a source device, which is a

component where a playback signal originates, e.g., DVD.
