Doepfer

A-123-2 is a voltage controlled highpass filter with four filter outputs (6, 12, 18 and 24dB slope). It also features voltage control of the resonance.These controls and in/outputs are available:Audio In with attenuator (Lev)Manual Frequency control (Frq)FCV1: Frequency control input (~ 1V/oct)FCV2:..

A-132-8 is an octal VCA and primarily planned for polyphonic applications. The module contains four VCA pairs. The amplification range for each VCA is 0 ... 1.  0V CV corresponds to amplification 0 (full suppression), +10V CV to amplification 1. Each pair includes two daisy-chained VCAs. One VC..

The A-105-4 is a quad filter for polyphonic patches. It is based on the SSM2044 / SSI2144 chip, meaning the same component used in Korg Polysix, Mono/Poly, Fairlight II, PPG Wave, Emu SP-1200 and many other classic synthesizers. The filter has a very rich sound character. Its resonance begins colori..

OVERVIEWThe popular Doepfer A-135 has been reduced to 8HP, making it one of the most compact voltage-controlled four-channel audio mixers on the market. The new version now offers separate All and Selected outputs for even more flexibility! The volume of each channel can be modulated via control vol..

OVERVIEWThe A-180-4 consists of four buffer circuits for control voltages. A buffer serves to avoid a voltage drop. This can occur due to different loads. The lower three units are each normalized to the previous output, so that the module can also be used as a buffered multiple by leaving the lower..

Noise / Random / T&H / S&HModule A-118-2 is the slim version of module A-118-1 and offers essentially the same features as the A-118-1. But the distances between the controls are smaller and rubberized small-sized knobs are used. In return the front panel has 4 HP only which is half the widt..

12dB Multimode FilterModule A-121-3 is functionally nearly identical to module A-121-2. Only the distances between the controls and sockets are smaller and rubberized, small rotary knobs are used. Therefore the front panel width is only 4HP compared to 8HP of the A-121-2. In the first place it is pl..

Dual linear/exponential VCAModule A-130-2 is the slim version of module A-132-3 and offers essentially the same features. But the distances between the controls are smaller and rubberized small-sized knobs are used. In return the front panel has 4 HP only which is half the width of the A-132-3. The ..

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..

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..

Quad Low Frequency Oscillator (LFO)Module A-145-4 is a simple quad LFO (Low Frequency Oscillator). Not a very "exciting" module, just a bread-and-butter device and a simple demon for work. Virtually in every modular system several LFOs are required for modulation purposes. The module contains four s..

Quad Passive SwitchA-182-2 is a simple passive module that contains four changeover switches, which are used to connect or disconnect the sockets of the corresponding socket triplet:in the upper position of the switch the upper socket of the corresponding socket triplet is connected to the center so..
