SERVICE MANUAL
IMPORTANT NOTICE
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.
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.
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).
Turn the unit OFF during disassembly and part replacement. Recheck all work before you apply power to the unit.

    DRX-1 Clock Circuit ClockGen regular clock Raw clock (CY2071) slow- (FPGA) loopfilter Fig. 13 The same can be applied for the audio clock. For this clock, a frequency of 8.192 MHz, 11.2896 MHz or 12.228 MHz is required. This depends on the sample-rate frequency(32kHZ, 44.1kHZ or 48kHZ)of the audio signal.
