GUIDE TO ASSEMBLY OF ERICA SYNTHS DELAY MODULE
If you are reading this, most probably, you are
about to build Erica Synths DIY DELAY module. The
module is 45mm deep, skiff friendly, has solid
mechanical construction and doesn’t require wiring.
Erica Synths DIY Delay is hi-fi delay module with
unique functionality typically found on advanced
factory-produced units. We developed a custom DSP
MCU board (comes pre-soldered and pre-
programmed) and delay algorithms for syncable up
to 800ms delays. Selectable Tape and Digital delay,
BPM Sync, Tap Sync makes the module ideal for
nuanced sound design. Furthermore Hold (freezes
the sound up to 800ms), Add (adds several layers of
sound on top) and Reverse (reverses sound in the
hold buffer) functions allow to create crazy sonic
artefacts.
The DIY Delay kit comes in three versions:
1) Set of 2 PCBs + MCU board,
2) Set of 2 PCBs + MCU board + mechanical parts
(PCB connectors and spacer)+ panel,
3) Full kit.
FEATURES:
• Tape Delay and Digital Delay algorithms
• Up to 800ms delay time
• Syncable (clock and tap) delay time
• Delay time divisions and multiplications
• Freeze, Add and Reverse
• Manually and CV controlled delay time, feedback
and dry/wet mix
SPECIFICATIONS:
• Max Delay time 800ms
• Sampling frequency 48khz 24bit
• Audio output amplitude 10Vptp
• CV amplitude (full span) -5V - +5V
• Panel width 14HP
• Module depth 45mm
• Power consumption 97mA @+12V,
33mA@-12V

The big knob sets delay time from 0 CCW to 800ms CW. When in
Sync mode (clock applied to SYNC input or you used TAP SYNC
button), knob becomes delay time multiplier of divider. Please note
that at low sync rates divider gets disabled, as the max delay time is
800ms.
Select the delay mode – Tape or Digital (no pitch shifting)
Adjust input level to avoid clipping
Use Tap Sync button to synchronize the delay time to the BPM. To
exit sync mode push and hold the button for 2”
Push the Hold button to record an incoming signal in the module
memory buffer. Record time depends on TIME setting, and it will
start to loop the recorded buffer. To exit looping mode, push the
HOLD button again. The LED will lit, when the hold mode is active
When in Hold mode, you can push the ADD button to add more
loops to the hold buffer

Hit the REVERSE button to reverse delayed signal. It also
reverses all loops in the hold buffer

This is SYNC input – the delay time will be synced to the incoming
clock and you can divide and multiply delay time via TIME knob. To
exit sync mode, push and hold the TAP SYNC button for 2”
12
This is delay time CV input
13
This is the Dry/Wet CV input that controls analogue crossfader
14
This is the Feedback CV input
15
Adjust feedback level! In full CW setting the module will go to self
oscillation
Adjust Dry/Wet setting manually! This is full analogue circuit, and
you also can control Dry/Wet via CV
This is the output of the module. We believe, you’ll enjoy
results!
