Module A-142-4 contains four simple envelope generators. The only time parameter is Decay and can be adjusted manuall by means of the Dec. control in the range 2 ms ... 2 seconds. The attack time can be adjusted internally by means of a separate trimming potentiometer for each sub-unit in ..

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 the envelope signal a Gate signal and an invers..

Module A-135-1 is a quad  voltage controlled mixer. It is made of 4 independent linear VCA's. The VCA outputs are mixed to a common output. For each VCA the following inputs and controls are available: audio input with attenuator, control voltage input with attenuator, gain (pre-amplification)...

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 behaviour of the control voltage inputs can be cho..

A-134-1 is a voltage controlled universal panning and/or crossfader module. If the module is used a voltage controlled Panning device one audio signal is panned to two different outputs.  If the module is used a voltage controlled Crossfader two audio sig..

A-133 is a special dual voltage controlled amplifier that enables both positive and negative amplifications. Negative amplification means in this context that the signal is inverted. The main application of the module is the processing of control voltages, e.g. ADSR or LFO but the module can be..

Module A-132-4 contains four identical voltage controlled amplifiers (VCA) with exponential control scales. Each VCA has two control voltage inputs (C1, C2), a signal input (In) and a signal output (Out). The control voltage inputs C1 and the signal inputs can be normalled by means of internal jumpe..

Module A-132-3 is composed of two identical voltage controlled amplifiers (VCA). Each VCA has a manual gain control and a control voltage input with attenuator. The character of the control scale can be switched to linear or exponential. All inputs and outputs are DC coupled. Consequently the VCAs c..

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 control Amp. and two control voltage inputs&nb..

Module A-132-1 (Dual Low Cost VCA) contains two voltage controlled amplifiers, with a linear response most suited to regulating the level of control voltages (ADSR amount, level of vibrato effect, etc.).In non-critical situations, though, its VCAs can be used to control audio signals.Amplification i..

Modules A-130 and A-131 provide voltage-controlled amplification. For audio signals, you would normally use the exponential VCA (A-131), and for control voltages, the linear VCA (A-130). It doesn't always have to be that way, though.The amount of amplification the VCAs provide is determined by the v..
