MATRIXSYNTH: Epicycloid Turbo Entubulator & Voluptron Vacuum Tube Eurorack Modules

Epicycloid Turbo Entubulator & Voluptron Vacuum Tube Eurorack Modules


Published on Apr 25, 2019 Perfect Circuit

"Epicycloid Engineering has two vacuum tube based modules and a dedicated power supply module for them. The Turbo Entubulator is a module that breaks out all of the functions of a 6AR8 tube to be voltage controlled and used with your other eurorack modules. This module can be used as a VCA, ring modulator, distortion/saturation effect, waveshaper and probably many other uses when patched in different ways.

The Voluptron is a four pole lowpass ladder filter, but with tubes instead of transistors.

Both of these modules receive 200V power from the Illuminox Prime module to make sure the tubes are running at full power.

EPICYCLOID ENGINEERING TURBO ENTUBULATOR

The Turbo Entubulator is Epicycloid Engineering's flagship module: a tube breakout module that can produce effects ranging from simple VCA-like behavior all the way to gnarly tube distortion, wavefolding, and more. By providing direct, patchable access to the tube's pins, one can create a number of novel behaviors that all exploit the brilliant and peculiar nonlinearities of the included 6AR8 tube.

The Turbo Entubulator provides static and CV control of Deflector Bias and Offset as well as Grid Control and Screen voltages, allowing a number of patchable tube effects. Built-in cathode bias controls and automatic gain control help to reign in particular behaviors from tube distortion to nonlinear waveshaping.

The Turbo Entubulator requires connection to the Epicycloid Engineering Illumonix Prime power supply.

TURBO ENTUBULATOR FEATURES

Fully broken-out tube module for creating a variety of amplification, distortion, waveshaping, and completely novel effects
Compatible with 6AR8, 6JH8, and 6ME8 tubes
Can act as everything from a simple VCA or saturation effect to a complex nonlinear wavefolder
Dedicated controls for Deflector Bias, Deflector Offset, Control Grid, Screen Grid, Cathode Bias, AGC, and Transformer DC Blocking
Requires connection to Epicycloid Engineering Illuminox Prime power supply



EPICYCLOID ENGINEERING VOLUPTRON

Voluptron is Epicycloid Engineering's take on the traditional modular ladder filter: a complex, tube-based design with a thick, unparalleled sound. Voluptron offers up to five octaves of 1V/oct tracking, with resonance up to self-oscillation. Additionally, the input can be used as a gnarly overdrive—one which impacts the cutoff frequency at higher settings, creating dynamic filtering effects. If you love the sound of a Moog ladder filter but wish it would extend farther into the dredges of tube-based distortion and nonlinearity, Voluptron is the right choice for you.

Note: the Voluptron requires connection to the Epicycloid Engineering Illuminox Prime power supply.

VOLUPTRON FEATURES

Tube-based ladder filter with extreme sonic signature
4–5 octave cutoff frequency range at 1V/oct tracking
Resonance extends into self-oscillation
Includes three 6ES8 tubes, but is compatible with a wide variety more
Audio input with gain into distortion
Input level impacts cutoff frequency at higher gain settings, creating dynamic filtering effects
Requires connection to Epicycloid Engineering Illuminox Prime power supply



EPICYCLOID ENGINEERING ILLUMINOX PRIME

Illuminox Prime is a power supply module specially designed for Epicycloid Engineering's range of tube-based Eurorack modules, providing 200V of power to such modules as the Turbo Entubulator and Voluptron. Eliminating the various issues with running tube-based modules solely on a standard Eurorack supply, Illuminox prime provides all the power needed to keep those tubes nice and toasty in optimal operating condition.

Illuminox Prime is designed for use ONLY with Epicycloid's line of tube-based Eurorack modules. The required external 15VAC adapter is included with purchase.

ILLUMINOX PRIME FEATURES

Power supply specifically designed for Epicycloid Engineering's tube-based modules, including the Voluptron and Turbo Entubulator
Provides high voltages required for tube operation without adding strain to your standard Eurorack PSU
Includes 15VAC adapter with universal AC input
