  • Description

Sproom, half space half room.

It´s based on the FV-1 DSP IC by Spin Semiconductor which got popular with some famous guitar pedal effects and is covering all types of quality reverbs, delays, chorus, flangers, tremolos, or combinations of them.

It´s stereo and operates with 6 MIPS at Fs=48KHz, or in other words excellent audio quality with a clean dry / wet path to adjust the amount of effecting.

It offers 3 banks with each having 8 different algorithms. In total 24 effects.

The input is normalized to R. Means with just plugging a mono source into the left input, the output becomes stereo.

Each algorithm can be controlled with one of the 3 potentiometers, or by conrol voltage.

Capable of -5 / +5V with the dedicated pot at around center position, or 0-10V with the pot fully closed. In other words, the pot acts as offset.

LED indication for clipping and CV ins.

The internal effects are tied to the IC and fixed. Bank 2 & 3 or EXT1 & EXT2 can be exchanged with EEPROMS on the backside.
