Erica Black BLACK BBD User Manual

BLACK BBD

THANK YOU FOR PURCHASING
ERICA SYNTHS BLACK SERIES MODULE!

Erica Black Series include high-end, unique functionality and superior quality
modules. Only the best, highest quality components are used, all inputs and
outputs are protected against undesired overvoltage. When designing Black
Series, put design and usability superior. Big knobs are assigned to functions that
make dierence in sound. Erica Black series consist of range of modules that are
needed to put together entire synth. Enjoy!

The Erica Synths Black BBD is one of kind analogue delay module. It features two
BBD lines: short, 1024 stage and long, 4096 stage, that work simultaneously and
you can smoothly fade between those two, thus creating distinct multitap eect.
Furthermore, an advanced BBD clock noise cancellation circuit is implemented
that reduces unwanted BBD noise without filtering higher frequencies of audio
signal. Most of parameters are voltage controlled, which allows to integrate the
module in complex modular setups.

FEATURES:

Full analogue design
Two BBD lines (1024 and 4096 stages)
Smooth crossfade between BBD lines
Built in LFO
CV control over Time, Feedback and Dry/Wet mix

SPECS:

Audio level 10Vptp
CV level (full span) -5V - +5V
Power consumption +95mA, -81mA
Module width 12HP
Module depth 35mm

TIME

This is delay time manual control.
Because of BBD clock suspension
circuit, delay time can be pushed in
extremely long regions, however in
that case some high frequency
artifacts may be heard due to
sample rate reduction. The Time
CV is added to the knob setting.

IN LEVEL

This is the input attenuator switch.
Select among full amplitude, half
amplitude and audio o.

BBD MODE

This control smoothly fades
between short and long delays.
Any setting in-between will result
in distinct multitap delay eect.

LFO RATE

Adjust the internal modulation
LFO rate. The internal LFO
controls delay time, and it’s
automatically disengaged, when
an external modulation signal is
connected. The LED gives visual
feedback on the LFO rate.

This is manual Dry/Wet mix.
The MIX CV is added to the
knob setting.

LFO SHAPE

Select the LFO shape. Three
shapes are available – triangle,
square and in-between shape –
mix of triangle and square.

INPUT

This is the audio input of the
module.

COLOUR

Even though the module has BBD
clock suspension circuit, the colour
switch provides extra lowpass
filtering of the signal. At top setting
no filtering is applied, at lower
settings increasing filtering is
present.

FEEDBACK

This is the delay feedback manual
control. In extreme clockwise settings
the module goes into self-oscillation,
and by adjusting delay time and
BBD mode settings, the module
becomes a drone machine. The FBK
CV is added to the knob setting.

CV LEVEL

This is the Time CV level attenuator.
If nothing is patched into TIME CV
socket, it controls the internal LFO
amplitude.

WET OUT

This is the WET signal output of the
module – use it for advanced
patches.

TIME CV; FBK CV; MIX CV;

These are CV inputs for Time,
Feedback and Dry/Wet mix.

OUT

This is the main output of the
module.

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.
