IMPORTANT NOTICEThis manual has been provided for the use of authorized Yamaha Retailers and their service personnel. It has been assumed thatbasic service procedures inherent to the industry, and more specifically Yamaha Products, are already known and understood by theusers, 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, weadvise all Yamaha product owners that all service required should be performed by an authorized Yamaha Retaileror the appointed service representative.

IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification orrecognition 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, andservice departments of Yamaha are continually striving to improve Yamaha products. Modifications are, therefore, inevitable andchanges in specification are subject to change without notice or obligation to retrofit. Should any discrepancy appear to exist, pleasecontact the distributor's Service Division.

WARNING: Static discharges can destroy expensive components. Discharge any static electricity you body may haveaccumulated 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.

WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and /or plastic (where applicable)components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) tocause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHAT-SOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes tosolder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food.

A STEREO and PARALLEL OperationBefore performing any following adjustments, set the unit as follows:1. Set the ATTENUATIONS at the MAX.2. Input terminal: Cannon connector pin 2 is HOT, pins 1 and 3 GROUND.3. MODE switch: STEREO4. Output terminal: RL = 4 ohm/more than 500 W5. Others: Both Channel operation is required, if no particular indication. Moreover, turn off the filter switch,

if no particular indication.

Adjustment Specifications1. Fan TestWhen turning on the power switch, confirm that both fans of right and left sides regulate at low speed.

2. Muting TestAfter applying power to the unit, the PROTECTION indicator should remain ON 2.5 +/-1 seconds to indicate that the protection circuitry is operating and the indicator should go out. NO signal is output while this indicator lit.

3. Idle Current TestConnect the input terminal to the GROUND and adjust the VR201 (A channel) and VR301 (B channel) that the DC voltage Vb between the pin 1 and pin 2of the CN202 (A channel) and the CN302 (B channel) should be 1.0 +/-0.2 mV. And After finishing all tests, adjust the Vb again to 1.0 +/-0.2 mV.

4. Input Terminal DC offsetConnect the input terminal to the GROUND and check that the DC voltage Vdc of the output terminal should be 0 +/-75 mV.

5. Gain TestCheck that the OUTPUT should be +22.1 +/-0.5 dBu, when a sine wave of 1 kHz at -10 dBu is applied to the INPUT. This test should be performed on PARALLEL operation.

6. Frequency Response TestFilter switch OFF:When a sine wave of 20 Hz, 1 kHz or 20 kHz at -10 dBu is applied to the INPUT, check that the output is 0 +/-0.5 dB at 20 Hz and -0.5 +/-0.5 dB at 20 kHz taking the 1 kHz as a reference.Filter switch SUB WOOFER:<MIN>When a sine wave of 25 Hz, -10 dBu is applied to the INPUT, check that the output is -3.5 +/-1.0 dB taking the 1 kHz as a reference at the filter switch OFF.<MAX>When a sine wave of 150 Hz, -10 dBu is applied to the INPUT, check that the output is -3.5 +/-1.0 dB taking the 1 kHz as a reference at the filter switch OFF.

Filter switch LOW CUT:<MIN>When a sine wave of 25 Hz, -10 dBu is applied to the INPUT, check that the output is -4.5 +/-1.0 dB taking the 1 kHz as a reference at the filter switch OFF.<MAX>When a sine wave of 150 Hz, -10 dBu is applied to the INPUT, check that the output is -3.5 +/-1.0 dB taking the 1 kHz as a reference at the filter switch OFF.

7. Harmonic Distortion TestWhen a high quality sine wave is applied at 20 Hz, 1 kHz or 20 kHz, the harmonic distortion should be as follows:

*This test should have been finished within 30 minutes.

8. Channel Separation Test8-1 Apply a -5 dBu, 20kHz sine wave into the channel A.8-2 Short the input for the channel B with a 600 ohm load.8-3 Set the output of the channel A at a reference of 0 dB.8-4 If channel B attenuator is set to the same as channel A, channel B output should be l ess than -65 dB. (RL = 8 ohm)

9. Noise Test9-1 Set the input attenuator to MAX.9-2 Short the input with a 600 ohm load.9-3 Measure at the output, noise level should be less than -65 dBm.9-4 Set the input attenuator to "∞", noise level should be less than -70 dBu.*Be careful that it is not affected by noise induced during this inspection.

10. Stability TestWhen a rectangular wave 10 kHz, -10 dBu is applied to the input and a capacitor 10 pF–0.47 µF is connected with 4 ohm load resistor in parallel, the overshoot and the ringing should be as follows. Oversshoot: Vp/Vo </= 1.8 Ringing: less than 5 wavesNext, when the 4 ohm load resistor is removed and the load is the capacitor 10pF–0.47 µF only, the overshoot and the ringing should be as follows. Oversshoot: Vp/Vo </= 2.5 Ringing: fade away in less than 7 waves and no oscilation

11. Protection Circuitry TestCheck that the relay does not work when you apply a sine wave of +5.0 dBu (XS350), +3.0 dBu (XS250) at 10 Hz to the input and adjust the input level to obtain a clipped output wave form.Next, check that when you apply a sine wave of 1 Hz, 0.0 dBu to the input, the signal is cut off within 2 seconds, and the PROTECTION indicator should light up.Finally, check that when no signal is applied, the amplifier would resume to normal operation within 10 seconds.

12. PC Limiter Circuitry TestCheck that the OUTPUT should be as follows with an oscilloscope when a sine wave of 0 dBu (XS350), -1.5 dBu (XS250) at 1 kHz is applied to the INPUT and the output is shorted with a 1 ohm load ( +/-5%). At this time, check the CLIP indicator lights.

B BRIDGE OperationBefore performing any following adjustments, set the unit as follows:1. Set the ATTENUATIONS at MAX.2. Input terminal: Cannon connector pin 2 is HOT, pins 1 and 3 GROUND.3. MODE switch: BRIDGE4. Output terminal: (A ch+, B ch+) RL = 4 + 4 ohm/more than 500 W5. Connection for measuring: Measure the output at the point as shown below.

Adjustment Specifications1. Gain TestCheck that the OUTPUT should be +22.1 +/-1.0 dBu, when asine wave of 1 kHz at -10 dBu is applied to the INPUT.

2. Frequency Response TestWhen a sine wave of 20 Hz, 1 kHz or 20 kHz at -10 dBu is applied to the INPUT, check that the output is 0 +/-0.5 dB at 20 Hz and -0.5 +/-0.5 dB at 20kHz taking the 1 kHz as a reference.

3. Harmonic Distortion TestWhen a high quality sine wave is applied at 20 Hz, 1 kHz or 20 kHz, the harmonic distortion should be as follows:

4. Noise Test9-1 Set the input attenuator to "0".9-2 Short the input with a 600 ohm load.9-3 Measure at the output, noise level should be less than -60 dBm. (LR = 8 ohm)9-4 Set the input attenuator to "∞", noise level should be less than -60 dBu*Be careful that it is not affected by noise induced during this inspection.

C Settings after the testThe attenuator should set to "∞".

The MODE switch should set to STEREO.

D Others0 dBu = 0.775 VWhen measuring noise level,use a DIN audio filter.
