AVR 260/230 Service Manual

Page 1 of 131

Each precaution in this manual should be followed during servicing.

Components identified with the IEC symbol

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

semiconductor "chip" components.

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

sufficient to damage ES devices.

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.

FRONT-PANEL CONTROLS

0

  Volume Control: Turn this knob clockwise to increase the volume, 

counterclockwise to decrease the volume. If the 

AVR

 is muted,  adjusting 

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

1

  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.

2

  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.

3

  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.

FRONT-PANEL CONTROLS

D

  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 

MULTI ROOM SETUP

 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.)

E

  Surround Modes: Press this button to select a surround sound 

(e.g.,multichannel) mode. The Surround Modes menu will appear on
