A-118-2 Noise / Random / T&H / S&H

The “Slim Line” module is a version of the classic analogue noise generator A-118-1 reduced to half the width (only 4HP). As with the other “Slim Line” modules, slightly smaller buttons and sockets with narrow, round nuts are also used here. The controls are at the top and the sockets are at the bottom, which … Read more

A-117 Digital Noise / Random Clock / 808 Sound Source

The A-117 Digital Noise / Random Clock / 808 Sound Source module is a discontinued model and will no longer be produced in the future. Status: February 2024 The Digital Noise Generator A-117 creates random, short impulses. The frequency of these pulses can basically be controlled, namely via the “Rate” controller or alternatively via an … Read more

A-118-1 Noise + Random Voltage

Like the A-117 Digital Noise, the A-118-1 is also a random noise generator. However, it does not work with feedback shift registers, but with the “natural” noise of transistors and thus generates a very typical “synthesizer” noise. Dieter Döpfer once explained to me that due to the component tolerances of these transistors, each A-118-1 sounds … Read more

A-149-1 Quantized/Stored Random Voltages

The A-149-1 Quantized / Stored Random Voltages is a lavishly equipped random generator that is based on the Buchla modules 265 and 266. There are two different sub-modules: Quantized Random Voltages provides random voltages whose level is within a “grid”, a quantization. These are then distances of 1 V at output “n+1” and distances of … Read more

A-152 Voltage Addressed Track&Hold / Switch

The A-152 Voltage Addressed Track & Hold / Switch module is by far the most flexible switching module presented here. It offers a bidirectional 8:1 or 1:8 switch that can be addressed via control voltage as well as switched sequentially via trigger signals (or switched back to the first level with a reset trigger). In … Read more
