Quick Start Guide
Controls
FREQ – use this control to set the SURGES
cutoff frequency.
SLOPE – use this switch to set the cutoff
slope for the low pass and band pass filters;
up for 24 dB/octave, down for 12 dB/octave.
RESO – use this control to set the resonance
level, emphasizing a band of frequencies
around the cutoff point. At extreme settings
the SURGES will self-oscillate.
INPUT 1 GAIN – use this control to set the
gain for input one. Higher settings will cause
the signal to be over-driven.
FREQ CV ATTENUVERTER – use this control
to set the level, and to invert if required, the
frequency control CV.
IN 1 – use this 3.5 mm TS jack socket to
input an audio signal with adjustable level/
overdrive from control 4. The LED above
will light when a signal is present and grow
brighter as the gain is increased.
FREQ CV IN – use this 3.5 mm TS jack socket
to control the SURGES' cutoff frequency from
an external CV source, via the attenuverter 5.
Range is -8 V to +8 V.
RESO CV IN – use this 3.5 mm TS jack socket
to control the SURGES' resonance level from
an external CV source. Range is -8 V to +8 V.
V/OCT CALIBRATION – if the volt/octave
tracking needs to be calibrated remove
this cover and use a suitable screwdriver to
adjust the trimmer below. Please note that
this should only be carried out by competent
personnel. See CALIBRATION below.
