AVR 160/230 Service Manual

1 of 116

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.

Power Indicator: This LED has three possible modes: 

 

: When the AVR is unplugged or the Main Power 

Switch is off, this LED is off. 
Standby

 

: Amber indicates that the AVR is ready to be turned on.

 

: When the AVR is turned on, this LED turns white.

NOTE: If the PROTECT message ever appears, turn off the AVR and unplug 
it. Check all speaker wires for a possible short. If none is found, bring the 
unit to an authorized Harman Kardon service center for inspection and 
repair before using it again.

Standby/On Switch: This electrical switch turns the receiver on, or places 
it in Standby mode for quick turn-on.
RDS: Activates RDS functions for FM Radio
Channel Level Control: Press this button to adjust the output level for 
any amplifier channel. It may be necessary to raise or lower the level of a 
specific channel to compensate for the placement of the relevant speaker in 
the room in relation to the listening position; e.g., the center channel speaker 
is further away from the listening position than the front left and right 
speakers, so that the dialogue is too soft to hear clearly.

To adjust the level of a channel, press this button once. If the desired channel 
is not displayed on screen and in the front-panel Message Display, use the 
Tuning Buttons to scroll to it. When the desired channel appears, use the 

M N

 

Navigation Buttons to change the level.

It is recommended that you avoid changing the channel levels after you have 
run the EzSet/EQ setup procedure described in the Initial Setup section, which 
properly adjusts all channel levels. See the Advanced Functions section for 
more information on manual speaker setup, including level adjustment.
Remote IR Sensor: This sensor receives infrared (IR) commands from the 
remote control. It is important to ensure that it is not blocked. If covering 
the sensor is unavoidable, use an optional Harman Kardon HE 1000, or other 
infrared receiver, connecting it to the Remote IR Input on the AVR 160’s rear 
panel.
Digital Input: To change the audio input for the current source to one 
of the six digital audio inputs or the analog input for the source, press this 
button and use the 

M N

 Navigation Buttons to change the input. Although 

any digital audio input may be assigned to any source, the analog audio 
inputs are all permanently dedicated to the source with which they are 
labeled.

M N

 Navigation: These buttons are used to navigate the AVR’s menus.

Set: Press this button to select the currently highlighted item.
Message Display: Various messages appear in this two-line display 
in response to commands and changes in the incoming signal. In normal 
operation, the current source name appears on the upper line, while the 
surround mode is displayed on the lower line. When the on-screen display 
menu system (OSD) is in use, the current menu settings appear.
Tuning: Press these buttons to tune a radio station.

AM and FM Antenna Terminals: Connect the included AM and FM 
antennas to their respective terminals for radio reception.
Component Video Monitor Output: If you are using one of the 
Component Video Inputs and your television or video display is component-
video-capable, connect these jacks to the video display.

NOTE: Due to copy-protection restrictions, there is no output at the 
Component Video Monitor Outputs for copy-protected sources.

Component Video 1&2 Inputs: If a video source has analog 
component video (Y/Pb/Pr) capability, and if you are not using an HDMI 
connection, connect the component video outputs of the source to one of the 
sets of component video inputs. Do not make any other video connections to 
that source.

NOTE: AVR 160 does not transcode composite video source signals to the 
component video format. 

Video Monitor Output: If any of your sources use composite video 
connections, connect this monitor output to the corresponding input on 
your video display. Composite video source signals are only available at this 
output.

Video 1, Video 2 and DVD Audio/Video Inputs: These jacks may 
be used to connect your video-capable source components (e.g., Blu-ray 
Disc™ player, DVD player, cable TV box) to the receiver.

NOTE: If a source is equipped with an HDMI output, it is preferable to 
connect it to one of the AVR’s HDMI Inputs. If the source does not have an 
HDMI output, use its component or composite video output, and make a 
separate audio connection.

Video 1 Audio/Video Outputs: These jacks may be used to connect 
your DVR, VCR or another recorder.
HDMI Inputs and Output: HDMI (High-Definition Multimedia Interface) 
is a connection for transmitting digital audio and video signals between 
devices. Connect up to three HDMI-equipped source devices to the HDMI 
inputs using a single-cable connection.

When you connect the HDMI Output to your video display, the AVR 160 will 
automatically transcode component video source signals to the HDMI format, 
but they will be passed through at the original resolution and will not be 
scaled. The AVR’s on-screen menus are visible when the HDMI Output is used, 
but only at 576i resolution. The main video source will not be visible.

NOTES: When connecting a DVI-equipped display to one of the HDMI 
Outputs:

Use an HDMI-to-DVI adapter.

 

Make sure the display is HDCP-compliant. If it isn’t, do not connect it to 

 

an HDMI Output; use an analog video connection instead.

Always make a separate audio connection.
