ADJUSTMENT PROCEDURE:

CAUTION:

Before making any adjustment let the unit heat-up at least 30 min.

Always check the DC voltages at the power supply.

ADJUSTMENT OF PSU:

1) The DC voltage in TP3 shall be + 150,0V.

Adjust with P202.

2) The DC voltage in TP1 shall be - 150,0V.

Adjust with P201.

ADJUSTMENT OFFSET IN TUBE-OP-AMPS:

1) The DC voltage in TP6 shall be <+/- 50mV.

Adjust with P1.

2) The DC voltage in TP7 shall be <+/- 50mV.

Adjust with P2.

ADJUSTMENT OF BASIC GAIN:

1) Apply a signal of 1 kHz, 0,0 dBU to the input of the equalizer.

2) Turn all gain controls at

"0"

and switches on

"OUT"

(except BYPASS).

3) Adjust the preset

GAIN

P3 (located on amp/psu PCB) to an output reading of 0,0 dBU.

ADJUSTMENT GAIN CONTROLS IN LOW/HIGH SHELVING AND BAND 1-3:

LOW SHELVING:

1) Apply a signal of 20 Hz, 0,0 dBU to the input of the equalizer.

2) Turn the

GAIN

-control a "0". Turn the freq. switch to "150Hz".

3) When switching between boost and cut, observe that the level is exactly the same

(<+/- 0,1dB).

Adjust with P2 located on the front PCB.
