Connect the DC voltmeter to sockets P6080,P6081,P6082,P6083,P6084 and P6086. After turn POWER to ON, adjust the trimming resistors R6040, R6041 and R6042 so that the reading of voltmeter becomes 7.0 mV. (Front and center channels) Adjust the trimming resistors R6043, R6044 and R6046 so that the reading of After adjustment, attach the top cover. voltmeter becomes 5.0 mV. (Surround and surround back channels) Confirm the voltage of points above after about five minutes. Front and center channels When less than 9.0 mV, readjust the resistors above so that the voltage becomes 9.0 mV. When 9.0 mV to 11.0 mV, you are not necessary to adjust. When more than 11.0 mV, readjust the resistors above so that the voltage becomes 11.0 mV. Surround and surround back channels When less than 6.0 mV, readjust the resistors above so that the voltage becomes 6.0 mV. When 6.0 mV to 8.0 mV, you are not necessary to adjust. When more than 8.0 mV, readjust the resistors above so that the voltage becomes 8.0 mV. Note: No load and No signal L ch. P6080R6042P6082R6041P6081 R6043R6044R6046P6083P6084P6086 R ch.C ch.
