Bias Adjustment SPA21

If anything in the output stage has been repaired, the bias needs to be readjusted.

Critical for the adjustment are that the mainsvoltage is 230V or 115V exactly. The temperature in the facility must be constant during the adjustment procedure.

Use the following measureingpoints and potentiometers to adjust bias:

Channel Measure Adjust

Front R JP9 R1

Front L JP8 R56

Surr R JP7 R55

Surr L JP6 R54

Center JP5 R53

These steps describe the procedure which is the same for all channels.

1. Switch the amplifier on or if it has been on burn-in, disconnect input signal and loads.

2. Let the amplifier run for 1h.

3. Adjust the bias to 9mV

4. Wait 1h

5. Measure the bias and if needed readjust to 9mV

6. Wait 1h

7. Measure the bias and if needed readjust to 9mV

8. Wait 1h

9. Measure the bias and if needed readjust to 9mV

Repeat step 5-9 until the bias are stabile.
