INSTALLATION
Remove module from packaging.
Power down your modular synthesizer and disconnect the power
cable from the wall outlet.
Attach the included power cable to the module’s power connector and
connect the other end to the power distribution bus in your EuroRack
synthesizer case. If you have a bi-colored ribbon cable the red stripe
should be on a same side with a bold white line on a pcb. In case if you
have a rainbow-colored ribbon cable the key is brown. Connector also
has a key which should match sikscreen on a pcb.
Position the module on the mounting rails in your EuroRack case and
screw down mounting screws. Power up! If your case does not turn on
properly then you have installed the module incorrectly. Simply power
down and make sure to follow the diagram when reconnecting the
module.

The SPUTNIK ENVELOPE FOLLOWER/PREAMP is a dual function module
that allows audio signals to be brought up to proper levels to be sonically
manipulated by other Eurorack modules or to be converted into control
voltage. The preamp section includes a balanced 1/4” TRS cable input jack
that can accept sound sources such as microphones, guitar pickups,
keyboards, drum machines, etc. Three selectable gain modes are available
via a switch with an additional gain knob to dial in the signal to the exact
level you need. The envelope follower section of the module features an
input jack for modular level signals and outputs for CV and pulses. Front
panel knobs give you control over input sensitivity and CV envelope decay
time.

EF IN/OUT JACKS
INPUT
Eurorack modular level audio input
(10V P2P). If no input is present, the
output of the preamp section is
normalized to the envelope follower
input.
PULSE OUTPUT
Outputs a 5V pulse when the CV
level (after the Sensitivity attenua-
tor) exceeds approximately 2.5V.
Pulses may trigger envelopes,
sequencers, or pluck a low pass
gate.
CV OUTPUT
Outputs a CV value (between 0 to
+10V) based on the amplitude of
the audio input. Allows audio to
control any number of CV parame-
ters on Eurorack format modules.
EF CONTROLS
SENSITIVITY
Acts as an attenuator for the
incoming audio signal, allowing
hotter signals to be brought down
below the pulse output threshold.
Simultaneously acts as a range
control for the envelope follower’s
CV output.
DECAY
Controls the decay of the CV output.
A lower setting allows for a quick CV
response that matches the audio
input while a higher setting allows for
more of a slew between amplitude
peaks.
PULSE RESPONSE
This switch selects between two
pulse response modes. Transient
mode produces short pulses based
on the CV output rises above
approximately 2.5V. Sustained mode
produces sustained pulses that are
held at 5V when the CV output is
higher than a ~2.5V threshold.
PREAMP
GAIN ATTENUATOR
Controls the amplification of the
input signal. At fully closed the
incoming signal will be completely
silent and at fully open the maximum
amount of gain will be applied.
INPUT
1/4” TRS balanced instrument input
jack.
GAIN MODE
Three gain modes (low, medium,
high) are selectable based on how
much amplification your audio input
requires. Gain is applied after the
Gain Attenuator.
IMPEDANCE
Two position switch for Mic mode for
balanced signals (such as
microphones) or Instrument mode
for unbalanced signals (guitar, bass,
or line-level audio such as
keyboards or drum machines).
OUTPUT
Amplified audio output.
