settings of the speakers.A static noise will be heard
cycling, in order, from the front left, center, right, and both
surround speakers. When the test tone is cycling, you may

2) DOLBY PRO-LOGIC CIRCUIT
Dolby Pro-Logic is a sound effect system for movies developed by the Dolby Laboratories Licensing Corp. IC10 (NJW1102) is
a Dolby Pro-Logic decoder IC. When an audio signal recorded using the Dolby Pro-Logic system is sent to this IC, the left,
right, center and surround components are separated. The surround signal component is delayed by the delay IC11
(NJU9702). Fig. 3 shows the configuration of the Dolby decoder.

Delay
With Dolby Pro-Logic, three center modes depend on the use of a center speaker as follows.
NORMAL:Bass frequencies are sent only to the Left and Right Front channels. Select this mode when the
Center Speaker is smaller than the left and Right speakers.
WIDE:Bass frequencies are sent to the Left, Center and Right speakers. Select this mode when the
Center speaker is approximately the same size as the Left and Right speakers.
PHANTOM:Center channel information is sent to the Left and Right speakers. Select this mode when you do
not have a center channel speaker.
3) STEREO CIRCUIT
In 3-stereo mode, surround sound is sent to front Left channel and front Right channel and no surround sound is sent to
surround channel.

CAUTION TO THE SERVICE TECHNICIANS
13
BEFORE RETURNING THE RECEIVER TO THE CUSTOMER
LEAKAGE CURRENT OR RESISTANCE MEASUREMENTS
SHOULD BE PERFORMED TO DETERMINE THAT EXPOSED PARTS
ARE PROPERLY INSULATED FROM THE SUPPLY CIRCUIT.
1.25A/250V
*NOTE
1. ALL RESISTANCE VALUES ARE IN .
K -1000W. M -1000K .
WWW
2. THE WATTAGE OF RESISTORS IS 1/4W, 1/8W UNLESS OTHERWISENOTED.
3. ALL CAPACITANCES VALUES ARE IN uF UNLESS OTHERWISENOTED. P=uuF
CAUTION THE PARTS IDENTIFIED WITH THE IEC SYMBOL
MARKS ARE CRITICAL FOR SAFETY. REPLACE ONLY WITH
TYPE IDENTICAL TO THOSE IN THE ORIGINAL CIRCUIT OR SPECIFIED
IN THE “PARTLIST” DO NOT DEGRADE THE SAFETY OF THE APPLIANCE
THROUGH IMPROPER SERVICING.
