4
5 Mix
Use control 5 to set the relative amounts of upward-
and downward- shifted signals present at the mix
output $. If the knob is turned fully clockwise or
anti-clockwise, only one of the signals is audible:
Mix = 0 : just the downward-shifted signal is heard
Mix = 10 : just the upward-shifted signal is heard
5. In / Outputs
! Audio In
Socket ! is the frequency shifter’s audio input. Use it
to patch in the audio signal you want frequency-
shifted.
" Audio Out
Output " relays the original signal, amplified.
§ CV 1
Patch a control voltage for modulating the amount
of frequency-shift into socket §. The level of voltage
control is set with attenuator 4.
As a rule, a slowly-changing voltage (e.g. LFO, ADSR,
Random, etc.) or the CV output from a MIDI-CV-
Interface (e.g. A-190, A-191) is used for this.
$ Mix Output
Depending on the position of control 5, output $
contains a mix of the downward and upward
frequency-shifted signals.
% Down Output
Output % contains just the downward frequency-
shifted signal.
& Up Output
Output & contains just the upward frequency-
shifted signal.
