Akai AX80 - Adjustment Procedure for Voice PCB; Preparation for the Adjustment; Offset Adjustment (Sawtooth Wave Level DCO-2)

OSC-1
Sets the frequency range. 8 feet is
the reference setting, and the
pitch can be transposed up or
down by one octave by using the 4
feetor 16 feet settings,
respectively.
16' 8' 4'
Turns the oscillator ON/OFF
as well as setting the waveform.
Sets the width of the pulse for the
pulse waveform. However, the E2
mode will function only when
= "is selected.
This selects the depth of the PWM
ag for the pulse width set for the E2
E | mode PW.
Note: The PWM will not function
when the E3 mode PW data is O.
Adjust the PWM speed.
* ThePWM will modulate
between the pulse width set for
the E3 mode PW and a duty
cycle 50% PW.
Turns on/off the sub-oscillator (1
octave 1
Sets the output level of OSC-1.
CONTENTS
Sets the frequency range.
Can be adjusted by 100 cents or
by tape.
This adjusts the OSC-2 cong T
frequency and can be used to
achieve a rich and mild sound by
deturning the OSC-2 oscillation
frequency from that of OSC-1.
The frequency (pitch) can be
adjusted over a range of +36
cents.
Turns the oscillator ON/OFF
