Random*Source Serge Resonant Equalizer (ResEQ)

¥84,900 (Tax excluded ¥77,182)
10-band filter EQ with resonance and feedback

Format: Eurorack
Width: 18HP
Depth: 25mm
Current: 55mA @ + 12V, 55mA @ -12V, 0mA @ + 5V

To protect the original signal voltage range of Serge, the signal handled by Random * Source Serge is smaller than the standard Eurorack module, which is 5V at Peak to Peak.It is not as small as the line level, but when using it with other companies' products, pass it through a signal booster or attenuator as needed.



MUSICAL FEATURES

The Resonant EQ is a unique 10-band filter module specializing in the generation and processing of electronic sounds.With the exception of the top and bottom two frequency bands, each band has a major 2th spacing and produces formant peaks and valleys that resemble acoustic instruments.

The Resonant EQ has three types of outputs: two COMB outputs for even and odd bands, and the remaining two outputs are identical and output a mix of all bands. There is no clear separation between each band, and manipulating either frequency knob affects both COMB outputs. This equalizer is also unique in that it can be set to resonate bands . When the knob is in the center position, the response of the output provided from the main EQ OUT is flat. When the knob is in the range of 9 to 3 o'clock, it sets a boost or cut of up to 12dB. When the knob is above the 3 o'clock position, the bands begin to resonate, simulating the natural resonance of the formant structure of an acoustic instrument. When the knob is below the 9 o'clock position, the band cut becomes stronger.

The Eurorack version adds a 2-input Input Mixer, which is also useful for adjusting the input gain and providing manual feedback.

A feedback section with a manual knob and phase switch to set the return amount allows the output signal to be returned to the input stage without patching.By inverting the feedback signal with the phase switch, you can create unusual feedback due to the phase canceling effect.

  • Red: Gate (ON: 5V)
  • White: 0V-5V unipolar signal (DC coupling)
  • Black: -2.5V to 2.5V bipolar signal (AC coupling)


About Serge
Serge Modular was originally developed as a system with different voltage and size from Eurorack, and now it is also Eurorack like this product, but there are also the following unique rules for jacks and voltage used. There is.

  • The voltage range used is smaller than a regular Eurorack module. In the case of an oscillator, the width of the upper and lower ends of a normal Eurorack is 10V (10Vpp), while that of Serge Euro is 4-6Vpp. The input to the filter is also designed according to the level, so when using with other companies' products, use a signal booster or attenuator as appropriate.
  • In Serge, the expected voltage for each jack is represented by a color.
    Red: Gate
    White: Unipolar (0V or more)
    Black: bipolar (assuming negative voltage as well as 0 V or more)
    In terms of signal speed, any jack will work at audio and CV rates, which is a feature of the Serge system.
