Test Equipment Channel Strip

Dials, Test Equipment Channel Strip Plugin - Hainbach - VST2, VST3, AU, AAX, CLAP

The treasured sound of 1950s electronics re-created

Dials is a detailed digital translation of a unique combination of 1950s electronic music hardware from composer and YouTuber Hainbach’s studio. It is made with the rich sound and experimental spirit of early electronic music studios in mind.

The basis of Dials is a re-purposed German vacuum tube radio broadcast device paired with a heavy-duty American bandpass filter. They form a channel strip like no other. The scientific and radio background of the equipment provides a tone that sets it apart, whether you are processing vocals, drums, or any other instrument. Due to the built-in compressor, it is perfectly suited to lend your voice-over the „larger than life“ feeling of great recordings of the past or make your drums sound like they could get past the door at Berghain. Speaking of which: if you are feeling adventurous, feed it impulses and hear it roar like Stockhausen at a Gabber party. 

While its roots are in the past, this is a truly modern device with an unparalleled sound. It can be used to sweeten your music or to experiment – it can even become an instrument in your hands. 

Dials is available for MAC, PC, and LINUX (VST, VST3, AU, AAX, CLAP, 64-bit only), and also as AUv3 and Standalone on the App Store.

Hainbach’s Channel Strip 

The sonic basis of the plugin is a combination of two units that serve as a channel strip in Hainbach’s studio. A modified German level transmitter from radio broadcast maintenance and a scientific high and lowpass filter. 

The Preamp

This 1950s/60s German measurement instrument was originally used to send a fixed level and frequency to a radio transmitter. On the receiver end, it could then be checked how much of that signal came through and what adjustments had to be made. Analog specialist Wojcek Czern of Rogalow Audio  (PL) discovered that it could be adapted to be a high-quality mic preamp on par with studio legends like the V72 and V76. It is Hainbach’s main preamp for voice, acoustic mono recordings and processing synths.

One welcome side-effect of this massive steel-tubed amplifier is that it compresses the signal pleasantly. Singing into it is a joy in itself. We analyzed the effect and made it adjustable, so you get the wonderful overtone rich gain of the preamp separately from the compressor. 

The Filter

Allison Labs filters were common in science labs and early electronic music studios. Unlike their German stepped counterparts, they could be swept (at least in parts). That allowed much more fine filtering of frequencies. Passively built, they offered the height of precision at the time. But be it because of the age of the unit or our changed perception due to digital technology: to today’s ears, they don’t sound precise at all. They sing beautifully, as their peaks ripple across the cutoff frequencies. This is especially noticeable if you play with the resonance, the only new feature we added. One note: don’t take the frequencies inscribed on the front to heart – they might be off considerably.

Drum Device

Soul-singer and Podcaster Jamie Lidell (Hanging out with Audiophiles) takes Dials further: he turned it into an 808-style drum machine. Download them here and experiment.

Filterbank A+B

In this Ableton Live set, Hainbach rigged 2 x 8 instances of it in two devices, Filterbank A and B. A is a tight band set, and B makes use of wider filter settings. Use the macro control 1-8 on each to raise the volume of each instance of Dials. This creates a filter bank like they were used in early electronic music studios. There are two noise files from our plugin “Noises” to get you going, but feel free to process any material with it. If you rig up a fader set or knobs to it, you can play it like an instrument, which is highly recommended.

Also available on iOS

Dials is available for iPhone and iPad on the App Store, as a AUv3 plugin and Standalone (IAA).

Hainbach Portrait


Based out of Berlin, Germany, electro-acoustic composer and “that guy with the sweaters” Hainbach creates experimental music that is both visceral and whimsical. Using esoteric synthesizers, test equipment and magnetic tape he creates one hell of a trip in his improvised live sets. He shares techniques on experimental music on his YouTube channel, which has attracted a regular audience of over 100000 subscribers. His music has been released on Seil Records, Opal Tapes, SA Recordings and misc.works.
