IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.
It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already
known and understood by the users, and have therefore not been restated.
WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in personal
injury, destruction of expensive components, and failure of the product to perform as specified. For these reasons,
we advise all YAMAHA product owners that any service required should be performed by an authorized
YAMAHA Retailer or the appointed service representative.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or
recognition of any applicable technical capabilities, or establish a principle-agent relationship of any form.
The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research, engineering, and
service departments of YAMAHA are continually striving to improve YAMAHA products. Modifications are, therefore, inevitable
and specifications are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, please
contact the distributor's Service Division.
WARNING: Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this buss).
IMPORTANT: Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

5. SPEAKERS SET
The input signal is automatically identified in the order of dts →DOLBY DIGITAL →PCM →Analog.
There are five sub-menu items as follows. The signals output from the DSP block are the same as 1. DSP THROUGH: DSP
0dB.
Sub-menu CENTER SP REAR SP MAIN SP MAIN LVL LFE/BASS
1 MAIN:SMALL 0dB LARGE LARGE SMALL 0dB SWFR
2 MAIN:LARGE -10 LARGE LARGE LARGE -10dB BOTH
3 CENTER:NONE NONE LARGE LARGE 0dB BOTH
4 LFE/BASS:MAIN SMALL SMALL LARGE 0dB MAIN
5 FRONT MIX:5CH LARGE LARGE LARGE 0dB BOTH
LARGE: Signals are output in all bandwidths.
SMALL: Signals lower than 90Hz are mixed in the channel specified by LFE/BASS.
NONE: The center contents are distributed to the MAIN L/R channels after -3dB.
6. DISPLAY CHECK
This program is used to check the FL display section. The display condition varies as shown below according to the sub-
menu operation. The signals are processed using EFFECT OFF (The L/R signal is output using ANALOG MAIN BYPASS.)
The video signal internal/external synchronization switching is controlled by the microprocessor. When the initial message is
displayed and all the FL segments light up, it is switched to the internal synchronization but other than that it is forced to the
external synchronization setting.
Also, except for the initial display, 128 pictographs for checking the OSD driver are used for the video signal output display.

Segment conditions of the FL driver and the FL tube are checked by turning ON and OFF all segments. Next, the operation
of the FL driver is checked by using the dimmer control. Then a short between segments next to each other is checked by
turning ON and OFF all segments alternately (in lattice). (In the above example, the segments in the second row from the top
are shorted.)
The analog switch settings for each sub-menu are as shown in the table below.
