in this video i will show how to adjuste output indicator for pionner blue serie amplifiers withe affordable tools
the steps of adujstement ares as folow:
turne one the apmifier al let's it warm up for 10min
connect a 8ohms 10W resistor to the output terminals
adjust the volume controle to the minimume
adjuste tone controle to centrale position
connect a 150mV 1khz SIN Signal generator to the AUX in
connect an AC votlemeter to the outputs terminals in parellele withe resistor
after that
adjuste the volume control so that the voltage on the output terminals read 9V AC
adjuste Vr1(Lch) and Vr2(Rch) of the indicator assembly so that the output power indicator read 10Watts
in our case we remplace the resistor withe 8ohms speakers and we get 150mV 1Khz ignal bay singal generator
of an android phone and we adjuste volume to get exactly 150mV.
