VC Performance Mixer Input ModuleA-135-4A is the main module. It is very similar to module A-138p, but with voltage control for all parameters (except gain). Also the front panels of A-135-4A and A-138p are very similar. The only difference are the additional LEDs which are used to display the magni..

VC Performance Mixer Envelope Follower ModuleModule A-135-4C is a four-fold envelope follower with ajustable attack and release time for each channel. The main function of the module is to derive four envelopes from the A-135-4A audio input signals. These voltages can be used to control parameters o..

Performance Mixer Output ModuleA-138o is the output module that can be combined with one or more A-138p.level controls for Left, Right and Auxoutput sockets for Left, Right and Aux (3.5 mm mono sockets)A-138o requires at least ine A-138p (no stand-alone use)http://www.doepfer.de/A138p.htm20 mA +12V2..

Modules A-138p/o are used to built a simple performance mixer (instead of an external stand-alone mixer). Module A-138p is the 4-fold input module, A-138o is the output module that can be combined with one or more A-138p.A-138p features:4 channelscontrols and inputs for each channelinput (3.5 mm mon..

A-138s is a simple but useful 4-in-2 mixing tool. It has four inputs available. Each input is equipped with an attenuator (Level) and a panning control that is used to distribute the signal to the left and right output. Beyond stereo mixing it is equally suited to create variable parallel routings. ..

A-111-4 contains four precision VCOs and has individual controls, inputs and outputs for each VCO available as well as a common control and output unit. After all the A-111-4 is very similar to four A-111-3 without LFO mode but built in output mixers for the three waveforms, and a master u..

Octal VC/Manual Programmable SwitchModule A-150-8 contains eight manually/voltage controlled switches. Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2). The switches are bi-directional, i.e..

Manual Gate (Receiver)A-173-1/2 is a module combo that is used to generate a manually controlled 1V/Octave CV signal and up to 15 manually controlled gate/trigger signals. Typical applications are the transposition of a sequence by means of the CV output (without the need of an external keyboard and..

The A-140-2 contains two classic ADSR envelopes, which can be configured using jumpers. For example, it is possible to determine which parameters are influenced by external control voltages or whether inverted CV signals are emitted in addition to normal signals.The module A-140-2 is composed of two..

A-141-4 is a quad voltage controlled Envelope generator and is primarily planned for polyphonic applications. The module contains four ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor). Common manual controls and CV inputs with po..

Module A-142-2 contains two envelope controlled VCAs behind a front panel with 8 HP only. Each of the two sub-units is the combination of a simple AD/ADSR/AR envelope generator and a VCA. The type of envelope can be selected by means of a toggle switch:AD: Attack-DecayAR: Attack-ReleaseADSR: At..
