The AVS-LFO-1
Dual LFO
User Guide
Thank you for purchasing from AvonSynth
Congratulations on your purchase of a brand new AvonSynth AVS-LFO-1
Dual LFO Eurorack Module. We trust that it will both serve and inspire
you as you create beautiful music with it for years to come.
In order to get the most out of your module, please ensure that you read
this User Guide in its entirety so that you fully understand all of its
functionality, and that you follow all necessary safety directions during use.

flat-cable power cord
2 x M3 Mounting Screws 2 x Nylon Washers
Installation
Step 1: Power your system off. Place the module in your Eurorack-compatible
rack in any convenient position. Affix the module to your rails using the
included mounting screws and nylon washers. Neglecting to use these
washers may result in unnecessary marking of the unit.
Step 2: Triple check the polarity of the power connector before connecting
the power cord to your power supply. Ensure that the -12v line marked on the
back of the module connects to the same end of the flat-cable that also
connects to the -12v line on your power supply. While AvonSynth
modules use shrouded connectors that make this process safer and more
reliable, some systems do not conform to this polarity standard, so careful
checking is always necessary. Connecting the module with incorrect polarity
can result in irreversable damage done to the module which cannot be
covered by warranty.
Step 3: Power up your system and start patching!

Features & Specifications
Fully Analogue Low Frequency Oscillators
6 HP wide (30mm), 20mm deep
Two independent and identical LFOs in one module
Current consumption: +12V 15ma, -12V 15ma
Frequency control range from several seconds per period, to approx. 20Hz
Simultaneous triangle and pulse outputs with swing of +/- 5v
Skew control which morphs triangle output between sawtooth, triangle, and ramp
Skew control also acts as PWM control of pulse output
Description of Functionality
Page 2 of 3
The bottom half of the module
is an identical reproduction of
the top half with entirely
independent frequency and
wave-shapes.
Controls the rate of the LFO's
oscillation from several seconds
per oscillation, to the edge of
audio rate. This control has an
exponential frequency response.
Morphs output waveforms, skewing
their shape in the direction of the knob's
travel. The centre point of the knob
produces the shape depicted above
each output. Turning the knob left and
right tilts the triangle output towards
the shapes depicted to the left and right
of the knob. It also doubles as a
pulse-width control for the pulse output.
Frequency Skew
Outputs an oscillating control
voltage with a default triangle shape
at a level of +/- 5 volts.
Triangle Output
Pulse Output
Outputs an oscillating control
voltage with a default square shape
at a level of +/- 5 volts.
