BLACK
K-PHASER
THANK YOU FOR PURCHASING
THIS ERICA SYNTHS BLACK SERIES MODULE!
The Erica Black Series includes high-end modules with unique functionality and
superior build quality. Only the best, highest quality components are used, all
inputs and outputs are protected against undesired overvoltage. When designing
the Black Series, we placed an emphasis on usability with the goal of providing an
enjoyable user experience. Big knobs are assigned to functions that make
dierences in sound. The Erica Black Series consists of a range of modules that
are needed to put together an entire synth. Enjoy!
The Erica Synths Black K-Phaser is our take on a classical, genre defining FX
unit – the Krautrock Phaser. It retains the original concept of 8 all-pass filters with
photoresistors, but we redesigned the filters and modulation circuit and added
several unique features. A dip switch allows for selecting the number of filter stages
involved in the resonance path, while the resonance attenuverter brings in
never-heard-before feedback artefacts, and most importantly – the SPREAD
mode detunes the all-pass filters for even more distinct behavior. A built-in voltage
controlled LFO with selectable waveforms expands the modulation possibilities
of the phaser and can be used as an independent modulation source for your
modular system as well. The Black K-Phaser is our tribute to the German electronic
music pioneers that largely shaped the sound of electronic music worldwide.
FEATURES:
8 all-pass filters with photoresistor control
Classic and Spread (filter detune) modes
Resonance attenuverter
Selectable resonance path
Built in VC LFO with a dedicated output
Wet output
PHASE
This is the manual phase shift control.
An external CV is added to the knob
position
MODE
Choose between CLASSIC filter
configuration, where all all-pass filters
are tuned the same, or SPREAD
configuration, where the filters are
detuned. The dierence is particularly
distinctive with the resonance added
CV LEVEL
This is the CV attenuverter. At 12:00,
no CV is applied, turning a knob
clockwise increases CV amount,
turning it counter-clockwise, the
incoming CV is inverted
LFO SHAPE
Select a built in LFO waveform
LFO CV IN
The built in LFO has CV control over
frequency – patch external modulation
sources here to add variation to the
modulation
LFO OUT
This is the dedicated LFO output –
it can be used as an independent
“module” to control other modules
in your system
INPUT
This is the audio input of the module
CV IN
This is the phase shift CV input. If nothing
is patched here, the internal LFO is
routed to the CV attenuverter

RESONANCE
A unique feature of the K-Phaser is the
resonance attenuverter. Clockwise
and counter-clockwise settings yield
dierent results sonically. The DIP
switch on the back of the module
allows for selecting the amount of
filters in the resonance loop.
LFO RATE
This is the manual LFO rate control.
An external CV is added to the knob
setting. The LED gives a visual
reference of the LFO rate
MAIN OUT
This is the main output of the module
WET OUT
This is the WET output of the phaser –
it outputs the phase shifted signal
only, not mixed with the original
signal
SPECS:
Audio level 10Vptp
CV level (full span) -5V - +5V
Max power consumption +38mA, -32mA
Module width 10HP
Module depth 35mm
88mA@+12V, 78mA@-12V

THE DIP SWITH
The DIP switch on the back of the
module allows for selecting the
amount of all-pass filters in the
resonance path. A classic Krautrock
Phaser had two filters in a feedback
loop as shown here, but you can
select any amount of filters that will
result in specific resonance
behaviour. Normally you would set
only one switch to the ON position,
but feel free to experiment with
several feedback loops
SAFETY INSTRUCTIONS
Please follow the instructions for use of the Erica Synths module below,
‘cause only this will guarantee proper operation of the module and
ensure warranty from Erica Synths.
Water is lethal for most of the electric devices, unless they are made
waterproof. This Erica Synths module is NOT intended for use in a
humid or wet environment. No liquids or other conducting
substances must get into the module. Should this happen, the
module should be disconnected from mains power immediately,
dried, examined and cleaned by a qualified technician.
Do not expose the module to temperatures above +50° C or below
-20° C. If you have transported module in extreme low temperatures,
leave it in room temperature for an hour before plugging it in.
Transport the instrument carefully, never let it drop or fall
over. Warranty does not apply to modules with visual
damages.
The module has to be shipped in the original packaging
only. Any module shipped to us for return, exchange and/or
warranty repair has to be in its original packaging. All other
deliveries will be rejected and returned to you. Make sure
you keep the original packaging and technical documentation.
This device complies to the EU guidelines and is manufactured RoHS conforming without use of lead, mercury,
cadmium and chrome. Nevertheless, this device is special
waste and disposal in household waste is not recommended.
