Waveform selector
F2 octave switch switches between (sinewave) or (trianglewave)
output on socket .
Common → F2 switch
changes the routing between the frequencies F1 and F2. In the upper
position, both frequencies F1 and F2 work independently and can be controlled separately by
their respective frequency knobs and/or CV inputs.
In the lower position, knob "F1/com" and sockets "F1/com CV" "F1/com CV 1V/Oct"
affect both F1 and F2. This coupling ensures that the ratio between F1 und F2 remains the same,
and tracks 1V/oct. using both frequencies within the FSK option. The ratio can only be changed
by the "F2" knob or the F2 CV inputs , .
Note that in this mode the frequency range is expanded and that for F2 four independent CV
inputs are now available.
Bypass
Ratio between the "AM in" signal input and the oscillator / output. The mixed
signal is provided at socket .
AM in level
Controls the input level from for amplitude modulation of / .
Gain adjustment
Primarily to suppress the oscillator frequency in ring modulation. The denter
in middle position "0" may be used as orientation.
This knob regulates an internal offset voltage between ca. ±2V which is added to the AM-input
signal, adjusted by knob . In counterclockwise positions of the potentiometer the / -
phase will be inverted (See also "Examples" in chapter 2.2 "FSK").
In some applications the "Gain" knob may be used to alter the waveshape (by adding more or
less voltage to your input signal); e.g. if you feedback the / output to the AM-Input
and adjust and carefully, the oscillator generates very overtone-rich waveforms.

is in
lowest position (" ").
The controller "Bypass" adjusts the AM-Input/ / -oscillator output ratio. Fully clockwise:
The / -oscillator output is 100%. Fully counterclockwise: The / -oscillator output is 0%,
AM-input ( ) is 100%. This is to mix the original to the "effect" signal (≙ "dry/wet") when the
oscillator is used as a ringmodulator.
output voltage: 4Vpp without AM; max. 10Vpp with AM.
output voltage: 8Vpp without AM; max. 14Vpp with AM.
In the banana version of the
XR22 VCO FT the
red
sockets signalize
low impedance outputs.
These outputs may
not
be grounded or patched together! This may damage the module.
