Rossum Electro Linnaeus Thru-Zero State-Variable Filter

Stereo state-variable filter module with the unique ability to linearly modulate its resonant frequency through zero into negative frequency, while maintaining stability
MFR# Linnaeus

Product Description

The Rossum Electro Linnaeus is a stereo state-variable filter that provides the unique ability to linearly modulate its resonant frequency through zero into negative frequency, while maintaining stability. With extensive voltage control of nearly every parameter, Linnaeus lets you manipulate the filter’s natural response curve in new ways, to create both subtle and dramatic timbral effects. And with a “one-knob-per-parameter” interface, Linnaeus inspires sonic creativity that invites (and rewards) real-time interaction.

Linnaeus’s cutoff/resonant frequency is exponentially voltage controllable from sub-audio to ultrasonic frequencies, while its resonant gain (Q) is exponentially voltage controllable from 0dB to greater than 60 dB.

Linnaeus’s channel output response characteristics are independently and continuously variable from Lowpass, through Bandpass, Highpass and Notch, to Low and High Shelving characteristics. Voltage control of the response characteristics are independently selectable for each of the two channels.

The linear thru-zero modulation is provided by an integrated modulation oscillator and/or an External Linear FM modulation input.

The voltage-controllable modulation oscillator can track the filter’s exponential frequency or operate independently. The modulation oscillator’s output waveform is continuously variable from Off through Sine, Triangle, and Sawtooth, to Square. The modulation oscillator output is summed with the external linear FM input and applied to the modulation index VCA, which controls the linear thru-zero modulation index from zero to 8X. The modulation index is, of course, also voltage controllable.

Features:

  • Ultra-wide frequency range, exponentially voltage-controllable from sub-audio to ultrasonic via precise 1V/OCT and attenuverted CV inputs
  • Thru-zero linear frequency modulation via an internal modulation oscillator and/or an external linear FM input
  • Variable linear modulation index, voltage-controllable via an attenuverted CV input
  • Resonance (Q) exponentially voltage-controllable from 0 dB to greater than 60 dB via 6 dB/V and attenuverted CV inputs
  • Continuously variable response characteristics independently selectable for each of the two channels via individual Enable controlsCharacteristics include Lowpass (12 db/oct and 6 db/oct), Bandpass, Highpass (12 db/oct and 6 db/oct), Notch, and Low and High Shelving
  • Voltage control of response characteristics via an attenuverted CV input, individual Enable controls let you independently enable or disable CV control of response for each channel
  • An integrated modulation oscillator with continuously variable waveform from Off through Sine, Triangle, Sawtooth and Square, its frequency can be exponentially voltage controlled via an attenuverted CV input
  • A Track control that lets the modulation oscillator precisely track the filter’s exponential frequency
  • Stereo inputs and outputs - Linnaeus can process a stereo signal or two independent mono signals. While the two channels share the filter’s cutoff/resonant frequency, the filter response characteristics can be independently controlled for each channel
  • The solid, high-quality construction you expect from Rossum Electro-Music
  • Linnaeus is 16HP wide and 25 mm deep
  • Power requirements (max): 140 mA +12 V, 25 mA -12 V, reverse polarity protected

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!
Matthew R.
I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!
Ryan F.
In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.
Martin C.
This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.
James P.
Thank you so much! Vintage King has been so fair and easy to work with. I can't thank you enough. It feels good to trust such a hefty purchase to folks who are so helpful and knowledgeable. Vintage King is a sound designers dream store.
Noa L.
You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!
Robby T.
I would recommend Vintage King to any one looking for top-class gear, unbeatable customer service and the best prices on the map!
Jake D.
My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
Rob M.
Thanks for your great service and getting this out today. You guys really are the Kings!
Alan B.
Better than expected! Truly impeccable service. Your team was professional, knowledgeable, provided speedy delivery above and beyond standard. Vintage King Audio is definitely my go to for all of my audio and information needs.
