Short circuit description :
In the below-described kit it comes to building a digital reverb pedal, which is used as a basis, the
BTDR- module of Belton / Accutronic.
The heart of the circuit is the BDTR-2 module which contains all of the components, such as A / D
converter, delay, and D / A converter incl. the associated filter (3xPT2399). The module has as its
predecessor 2 separate audio outputs, one of which can use a sound control (tone control) is unused.
The module requires only a voltage of + 5V that is generated on the circuit board by a 78L05 from the
9V supply voltage.
The only active components, a dual TL072 op amp is used, which amplifies the input signal by a factor
of 2 and summed at the output with the original signal.
As controls one potentiometers are used, which the reverb level (Mix). Switching the effect onf/off
with a hardware True bypass using a 3PDT switch and LED indicator.
Due to the compact double side through-hole board, the structure is relatively simple and is described
on the following pages.
