Enveloppes VCAs et Mixers - Claviers & pianos

Module A-138c is a four channel mixer, that allows to add or to subtract four incoming voltages to the output signal. In the middle position of the corresponding control the amplification is zero. Turning the knob counterclockwise the signal is subtracted...

Les module A-130 et A-131 sont des modules d'amplification contrôlable en tension. Pour du signal audio, on utilise normalement le VCA exponentiel A-131, et pour les controles en tension le VCA lineaire A-130, mais les 2 sont utilisables dans les 2 ...

Module A-134-2 contains two identical voltage controlled crossfader units. Each unit has two voltage controlled amplifiers (VCAs) with opposite control behaviour available. The outputs of the two VCAs are mixed together to obtain a common output. The beha...

A-101-2 is a vactrol based combination of Low Pass filter (LP) and VCA and was inspired by the Buchla module 292. The term Low Pass Gate was created by Don Buchla and stands for a module that can be switched between low pass and VCA. The control (manually...

We call the A-101-9 an universal vactrol module. It contains two identical sub-units. Each unit has two vactrol outputs available that are controlled manually (Man control) and by an external control voltage (CV In) with attenuator (CV). A vactrol is a co...

Module A-142-1 is a voltage controlled envelope generator. The only time parameter is decay (like TB303). Decay may be adjustes manual and via voltage control input (with attenuator). The envelope output is displayed with LED control. Additionally from th...

Module A-132-2 contains four linear VCAs with a common level control section for all four VCAs. The module can be used for all applications of simultaneous amplitude/level control of four different audio or CV signals. The module has a manual level contro...
