MON 0 CRUISE ADJUSTMENT

TUNING
7 Set the MONO PlTCH (left side) in the middle and tune the monophonic section
by trimmer Pdi

KEYED/IND TRACKING ADJ.

- Insert TRUMPET and PRESEI, press the highest C [last key on the right).
Read, bv a DMM [Digital Multi Meter), across Rd67 (1k2) 1V. voltage. The Trim-
mer Adjustment is m.

VCF ADJ.

7 insert FLUTE and FREE, CUT OFF downwards (minimum level), RESONANCE
"upwards" (maximum leveil. Adjust trimmer Pd3 in such a way that the VCF
oscillating frequency is the same as the fundamental of the pressed key.

LFO ADJ.

- Leaving the FLUTE inserted and rerinsening the FREE, set on the LFO with
DEPTH "upwards". lnsen the DMM between the collector at BC 416 (T091 and
ground. Then adjust trimmer Pd4 for a value of 4,39 V.

VCA ADJ,

_. Shon-circuit the diode Dd14, insert FLUTE, cut out the LFO with the VOLUME
upwards. Insert the DMM between the collector of EC 416 (T117) and ground.
Then adjust trimmer Fd5 for a value of 4,39 V.

OFFSET LFO ADJ.
~ Adjust Pdfi in such a way that, with TRUMPET and LFD inserted, DEPTH and
SPEED "upwards, the sound is still acoustically in tune.

OFFSET VCA ADJ.
- Set on PICCOLO and FREE, CUT OFF "upwards", RESONANCE and A'I'I'ACK
downwards" and adjust Fd7 in such a way that the attack sound is clickless"
