BIAS ADJUSTMENT
Instruments, materials and tools:
- Audio Generator
- Dual Trace Oscilloscope
- Digital Voltmeter (or Multimeter)
- 4Ω500W and 8Ω100W Resistors
- Temperature Meter
Setup:
- Connect the Audio Generator to the input and set it to output at 2KHz sinusoidal signal.
- Insert the temperature sensor through the interstize between the heatsink and R93 (PTC).
- Connect the 4Ω500W resistor to the amplifier output instead of the woofer speaker and 8Ω100W instead of tweeter speaker.
- Connect the oscilloscope probes (setting 20V/div.,1ms/div.) on the loads.
- Insert the voltmeter terminals on R107.
ADJUSTMENT PROCEDURE
1) Turn on the amplifier, pressing "UP" "DOWN" and "MIDI" simultaneously, check that the display shows "C".
2) Set the input signal to 0dB (0.775Vrms).
3) When the temperature has reaches about 45°C (109°F) set the signal input to minimum (0 or - ).
4) Adjust the trimmer R111 to read a voltage of 6mV ±0.1 on the multimeter.
5) Check that the voltage across the R108 resistor has the same value.
6) At the same temperature condition, adjust the VR1 trimmer to read 2.2mV ±0.1 at R24 resistor.
7) Check that the voltage on the R25 resitor has the same value.
Veryfing:
1) Increase the input level to obtain an output voltage about of 0.5Vpp.
2) Check with the oscilloscope that the output signal is without a cross-talk distortion and eventually slightly
adjust the R111 or VR1 position until distortion disappears.
(Note: the voltage value across the R107 or R108 resistor must not exceed 10mV and the R24 or R25 resistor must
not exceed 4mV).
LIMITER ADJUSTEMENT
1) Increase the input level to 10dB, adjust the trimmer VR1 until clipping distortion disappears.
2) Verify tha the led change colour from green to red.
3) Re-connect the speakers instead of the 4Ωand 8Ωresistors.
