This is a basic reverb module constructed around the Belton BTDR-2H Reverb Module and can be used as a replacement for a spring reverberation unit.

From a single input, two channels of raw reverb are generated. The outputs are decorrelated to generate a form of stereo output. Individual mix outputs are also provided, allowing the input/reverb mix for each channel to be independently controlled via panel pots.

An additional feedback function is provided for emphasizing the effect, or even for generating screaming feedback.

Three delay lengths are offered:-

Short Delay: T60 = 2.0 seconds
Medium Delay: T60 = 2.5 seconds
Long Delay: T60 = 2.85 seconds

 

T60 is defined as the time it takes for the sound pressure level to reduce by 60dB, measured after the generated test signal is abruptly ended.
