BIAS ADJUSTMENT
Instruments, materials and tools: - Audio Generator - Dual Trace Oscilloscope (earth ground floating) - Digital Voltmeter (or Multimeter) - 2x4E 220W Resistor - Temperature Meter Setup: - Connect the audio generator to the input (CN3) and set its output at 1kHz sinusoidal signal. - Insert the temperature snsor through the interstize between the heatsink and R82 (PTC). - Connect the 4E 250W resistor to the amplifier outputs - Connect the oscilloscope probes (setting 20V/div.,1ms/div) on th loads. - Insert the voltmeter terminals on R115. - Turn VR1 and VR2 clockwise up to end-stroke ADJUSTEMENT PROCEDURE 1) Turn on the amplifier. 2) Set the input signal to 0dB (0.775Vrms). 3) When the temperature has reaches about 50°C (121°F) set the signal input to ). minimum (0 or 4) Adjust the trimmer VR1 to read a voltage of 15mV±0.05 on the multimeter. 5) Check that the voltage across the R114 resistor has the same value. 6) At ssame temperature condiction, adjust the VR2 trimmer to read 15mV±0.05 across R70 resistor. 7) Check that the voltage on the R69 resistor has the same value. Verifing: - Increase the input level to obtain an output voltage about of 0.5Vpp. - Check with the oscilloscope that the output signal is without a cross-talk distortion and eventually slightly adjust the VR3 or VR2 position until distortion disappears. - The voltage value across the R70, R69, R114, R115 resistors must not exceed 18mV
