Thanks for your Befaco purchase! Before you plug this module in...
1. Disconnect your cabinet from mains.
2. Triple check the power cord polarity. The colored line on the cable
(pin number one) is the -12V rail.
3. If you plug the module backwards you might burn it and,
unfortunately this is not covered by the warranty.
4. If you have any questions about this product please send them to:
-12V
Introduction
Thanks for choosing Befaco’s spring reverb module.
This is a versatile implementation to drive a spring tank.
It has two voltage controlled inputs, one routed straight
to the tank and another to dry/wet and tank. Voltage
control of the MIX is also possible.
It has two outputs. MIX (IN1+Reverb tank output) and
WET (just reverb out) output. With this we get a exible
topology that allows external feedbacks, control the
amount of signal getting into the tank or use the input
VCAs to control the mix of signals in the tank.
The sliders and LED metters, both at the input and
output of the tank, provide a direct visual feedback of
the signal levels. Allowing a high control and optimum
utilisation of the reverb tank.
Connecting the module
ALWAYS MAKE THE CONNECTIONS
WITH THE SYNTH SWITCHED OFF!
You could damage your module otherwise.
RCA connectors must be plugged as follows:
IN from the module to OUT on the tank.
OUT from the module to IN on the tank.
SPRING REVERB USER MANUAL
In/Out reference
1. IN1
This input signal is sent both to the mix and reverb tank.
The amount of signal sent to the tank is controlled by
Slider_IN1
2. IN1 SLIDER
VCA level of IN1. Controls the amount of signal sent to
the tank. When a CV is present at IN1_CV this slider acts
as an attenuator of this signal.
3. IN1 CV
CV control for the VCA at input 1.
4. IN2
This input signal is sent straight to the reverb tank. The
amount of signal sent is controlled by Slider_IN2
5. VCA LEVEL OF IN2
Controls the amount of signal sent to the tank. When a
CV is present at IN2_CV this slider acts as an attenuator
of this signal.
6. IN2 CV
CV control for the VCA at input 2.
7. HPF
The audio going to the tank passes thru a High pass
lter. This potentiometer controls cuto of the lter. At
minimum setup there is no ltering.
Its purpose is to avoid saturating the tank with low
frequencies.
8. PEAK METER
Shows the amount of signal fed to the tank. Green shows
optimum level, orange high amplitude and red shows
saturation of the tank.
9. WET
Direct output from the Reverb Tank
10. VU METER
Level of the audio signal getting out of the tank. It’s
advisable to keep this level below red to avoid saturation.
11. DRY WET POT
A classic DRY/WET control. It’s the mix between signal
present in IN1 and the output of the tank.
12. MIX CV
CV control for the DRY/WET pot. This signal is added to
the setup of the potentiometer.
13. MIX
Audio output of the mix.
