  • Type/ Oscillator
  • Width/ 8HP
  • Power/ +90mA/-30mA
  • Depth/ 60mm

 
A-110-4 is a so-called Thru Zero Quadrature VCO. The term “quadrature” means in this connection that the oscillator outputs sine and cosine waveforms simultaneously. The term “Thru-Zero” means that even “negative” frequencies are generated. But this is a bit misleading term as negative frequencies do not really exist. “Negative” means in this connection simply that the sine/cosine waves will stop when the linear control voltage reaches 0V and continue with the opposite direction as the linear control voltage becomes negative and vice versa.

The module has two control sections: linear and exponential. The exponential section consists of the XTune control, the 1V/Oct input and the XFM input with the corresponding attenuator XFM. The exponential control voltage is the sum of these three voltages. The linear section consists of the LTune control and the LFM input with the corresponding attenuator LFM. The linear control voltage is the sum of these two voltages.

A-110-6 Trapezoid Thru Zero Quadrature VCO

 

  • Type/ Oscillator
  • Width/ 12HP
  • Power/ +80mA/-70mA
  • Depth/ 61mm

 
A-110-6 is a Trapezoid Thru Zero Quadrature VCO. The module is based on an idea by Donald Tillman from 2003 but has been revised for the use of modern electronic circuits.
The term “quadrature” means in this connection that the oscillator outputs two trapezoid waves with 90 degrees phase shift. The other waveforms, triangle, sawtooth, rectangle and sine, are also available as quadrature pairs. This and the capabiltiy to linear and Thru-Zero frequency modulation, make the A-110-6 a unique sound source with a wide sonic palette. In addition, there´s a switchable LFO mode (frequencies divided by 100).

A-111-2 High End VCO II

 

  • Type/ Oscillator
  • Width/ 14HP
  • Power/ +70mA/-50mA
  • Depth/ 55mm

 
The successor of the A-111 High End oscillator is an utterly precise analog VCO/LFO with a extremely big frequency range, immaculate tracking over at least ten octaves and nearly perfect waveforms.
With linear and exponential FM, pulse width modulation, two simultaneous types of sync and attenuators on all CV inputs the module is really well-appointed.

Not less than four frequency controls make tuning an ease:

– switch for LFO or VCO range
– octave rotary switch with six positions
– fine tuning control (approximately one octave range)
– coarse tune control (approximately one semitone range)

A-111-3 Micro Precision VCO

 

  • Type/ Oscillator
  • Width/ 4HP
  • Power/ +40mA/-40mA
  • Depth/ 65mm

 
The Micro Precision VCO is a space-saving and utterly precise analog VCO/LFO with a extremely big frequency range, immaculate tracking over at least ten octaves and nearly perfect waveforms.
Basically it is the same circuitry like the High-End VCO A-111-2 but with reduced functions and controls. Yet it is super suitable as a modulator for exact linear FM and much more.

The A-111-3 has two elements for setting the frequency: a switch selecting between LFO and VCO mode as well as a tune control with a jumper-selectable range:

– jumper position 1: 16Hz to 20 kHz
– jumper position 2: 16Hz to 70Hz
– without jumper: 16Hz to 22Hz

The XM potentiometer can be used as a fine tune control as long as nothing is patched to the XM socket.

A-113 Subharmonic Generator

 

  • Type/ Oscillator
  • Width/ 26HP
  • Power/ +120mA/-120mA
  • Depth/ 90mm

 
Module A-113 is a new sound source that derives from an incoming pulse signal four so-called subharmonics (German: Subharmonische).

The term subharmonics was introduced by Oskar Sala in connection with his so-called Mixtur-Trautonium.

A subharmonic means in this context a sawtooth wave (German: Kippschwinger) whose frequency is derived from a master frequency and the master frequency is an integer multiple in the range of 1…24 of the subharmonic – in other words: the master frequency is divided by an integer 1…24 to obtain the subharmonic.

Pay attention that the output waveform of a subharmonic is sawtooth (as also used in the original Trautonium) and not sine.

The term subharmonics is somewhat misleading.

The master frequency comes e.g. from an A-110 or A-111 to the frequency input of the A-113. The frequency dividers of the 4 subharmonics is adjusted with up/down buttons as displayed with 2 character LED displays. The subharmonics are available as single outputs and as mix output with adjustable levels for the subharmonics.

A-114 Dual Ringmodulator

A-114 Dual Ringmodulator

 

  • Type/ Utility
  • Width/ 4HP
  • Power/ +40mA/-40mA
  • Depth/ 40mm

 
Module A-114 contains two separate ring modulators.

A ring modulator outputs the product (Multiplication X • Y) of the signals at inputs X and Y.

It's similar to a VCA, but whereas a VCA only responds to positive voltages at the inputs (2-quadrant multiplication), the ring modulator responds to both positive and negative voltages (4-quadrant multiplication).

The ring modulator thus provides a refinement of amplitude modulation (AM).

Ordinary amplitude modulation will output the original carrier frequency fC as well as the two side bands (fC – fM, fC + fM) for each of the spectral components of the carrier and modulation signals – but ring modulation cancels out the carrier frequencies, and just lets the side-bands pass to the output.

A ring modulator is used for the production of bell-like sounds, alien voices, or just to produce new timbres.

A-116 Voltage Controlled Waveform Processor

 

  • Type/ Wave Shaper
  • Width/ 8HP
  • Power/ +20mA/-20mA
  • Depth/ 40mm

 
Module A-116 provides voltage-controlled dynamic waveform modification of audio signals.

It can produce new waveforms from the standard VCO shapes, and modulate these changes in real time.

The signal first of all goes through an input amplifier, which can attenuate the signal as well as amplify it by up to a factor of 2.

After the input amplifier, the signal goes through two parallel processors: a clipping circuit, and an asymmetrical amplifier.

The processed signals are added together and sent to the output.

Clipping-Level and Symmetry amounts are not just manually controllable, but can also be modulated by control voltages, to produce complex, constantly changing waveforms.

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

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

 

  • Type/ Noise
  • Width/ 8HP
  • Power/ +20mA/-10mA
  • Depth/ 40mm

 
Module A-117 is a combination module, including a digital noise generator and an 808 source.

The digital noise generator uses random sequences of square waves (18 step shift register with multiple feedback), whose rate can go from random clicks to pure noise.

The colour of the noise is very different from the analog noise produced by the A-118.

In addition to a manual setting, the rate can be controlled by an external clock – eg. VCO, LFO or MIDI clock.

The 808 Source aims to re-create the sort of multi-oscillator array that was used in Roland's TR-808 and 606 drum machines as the basis of the sound of the hi-hat, cymbals and cowbell.

The cowbell mix uses two oscillators, and the cymbals mix six.

A-118 Noise / Random

 

  • Type/ Envelope
  • Width/ 8HP
  • Power/ +34mA/-18mA
  • Depth/ 28mm

 
Module A-118 is (as you might have guessed) a noise and random voltage generator.

It produces three types of signal: white noise, colored noise, and random voltage.

White and colored noise can be used as audio sources, and also, in conjunction with a sample and hold module, as control voltages, and the random voltage is a useful source of voltage control, especially for its low frequency content.

The A-118 gives you the ability to mix the relative amounts of Red (low frequency component) and Blue noise (high frequency component) in the colored noise output.There are knobs to control the rate of change and amplitude of the random voltage, and two LEDs indicate the state of the voltage at any one time.
