Mixers

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..

Polyphonic voltage controlled mixer / Suboctave generatorModule A-135-5 is a combination of a voltage controlled polyphonic mixer and a polyphonic suboctave generator. It is made of 12 voltage controlled amplifiers (VCAs) which are arranged in form of a 4x3 matrix. Herewith up to three four-voice po..

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. ..

Module A-138 is a four channel mixer, which can be used with either control voltages or audio signals. Each of the four inputs has an attenuator, and there's a master attenuator, so that the mixer can be used at the end of the audio chain - ie. it can be used to interface directly with an external m..

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 from the output sum with increasing amount. ..

Module A-138d can be used in two different ways:as a crossfader module within the A-100as an insert module for external effect units (e.g. guitar stomp boxes) with dry/wet controlIf the module is used as a crossfader within the A-100 the two audio signals are connected to the sockets In 1 ..

Interrupting MixerModule A-138i is a four channel mixer with an additional mute switch for each input. On top of that it is equipped with two types of single outputs and a dual mix output. All inputs and outputs are DC coupled. Consequently the VCAs can be used to mix both audio and control voltages..

Module A-138m is a  4 x 4 matrix mixer with switches for unipolar/bipolar mode for each column. Unipolar means that the controls work as attenuators. Bipolar means that the controls work as polarizers. In this mode the amplification is zero in the middle position of the corresponding control. T..

Narrow (Mini) MixerModule A-138n is a simple four channel mixer, which can be used with either control voltages or audio signals. Each of the four inputs has an attenuator available. The output is twice available (two sockets, hard-wired like a multiple).The module is the slim version of module A-13..

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..
