Used in Excellent Condition.
Manufacturer Description: The AION 921 VCO is a variable waveform generator which produces
frequencies ranging from sub-audio (LFO) to 40.000 hz. Four waveforms
are available: sine, triangular, sawtooth and rectangular (with variable
duty cycle A.K.A. pulse width modulation).
Both fixed and variable levels can be obtained from the front
panel output jacks. Nominal frequency and range controls (octave) are
found at the top of the module.
Voltage controlled rectangular width (VC-PWM) is set by the knob
in the upper center (left) with the accompanying voltage input jacks.
Multiple frequency control inputs 1 and 2 can be plugged into
this module in parallel. Control input 3 is used via the pot for linear
frequency response (Liniar FM). All waveform outputs can be used if
desired.
This is what we consider an improved version of the Moog™ 921
VCO, not a direct clone. Improvements were made concerning tuning and
stability issues.
Frequency range:
0.01 hz - 40.000 hz
Range switch:
sub audio - 0.01 - 400 hz
audio - 1 - 40.000 hz
Scale switch:
2 or 12 octave frequency span.
Auxiliary outputs:
2 jacks (one normal, one inverted) with selected waveforms
(sine, triangle, sawtooth, inverted sawtooth rectangular and inverted
rectangular).
Waveforms amplitude controllable from 0 to maximum.
Hard and Soft synchronisation selectable via a switch.
Synch must be "OFF" (center position) when synchronisation is not beeing used, otherwise it will sound out of tuning.
