ELC24 v3

ELC24 v3

What’s new?

  • band isolated mid range and high shelf combined. This means low cpu, fast loading times and no repeated characteristics, for accurate whole emulation when using all three instances together.
  • Improved pre amp
  • now bundled sample rates
  • N4 and N3 JPN Skin

Isolated Mid and high shelf-


The eq skin can be used for two different presets.


For complete emulation use Bass>H L>PRE in series.




As with all release please make sure you have the latest version of nebula installed, also please check the faq regarding any questions before contacting me.

Here’s a few words on the ELC24 STEREO EQ from Neil Perry:

So we had 3 chassis to work on!! …. with these basic chassis, Raw State has spent considerable design and listening time to ensure the original units’ great quality was not compromised. Careful selection and auditioning of components was carried out to ensure good sonic characteristics were maintained.

The design is passive circuitry based upon the classic R – C – L components ( resistors, capacitors, inductors ). The original design was very nice sounding but with some obvious ‘problems’. The high and low frequency EQ curves were ‘strange’ … we are not sure but they may well have been optimised for disk cutting. We have redesigned these curves to be more in keeping with a unit ideal for mix / mastering work. ( We have paid particular attention to the frequency curves from the legendary Decca / Raw State Passive EQ units! )

Also the output stage needed some redesigning to be able to drive a reasonable load at good level.

Balancing is naturally by transformers, as it was felt the addition of audio transformers is so much a part of classic- sounding vintage equipment.

We have carefully matched input and output impedances to ensure the Eq characteristics are well controlled and musical. We eventually used ( Ex Neve ) Marinair input transformers. The output transformers are Marinair type T1501.

Typical Performance:

Fixed Hf EQ centred at 18 kHz

Max. Boost and Cut approx. 12 dB. Switched in 3 dB steps

Mid Band EQ Switched at 1.4 – 2.8 – 4.0 and 5.6 kHz

Max. Boost and Cut approx. 10 dB. Switched in 2 dB steps.

Fixed Lf EQ centred at 50 Hz

Max. Boost and Cut approx. 12 dB. Switched in 3 dB steps.

Maximum level into 10K better than +22 dB @ 1 kHz

Noise ( Eq controls flat ) better than -82 dB WTD

But the best thing to do is try a unit and listen

Note: Decca, Neve, Marinair, Elcom are registered trade marks.

This EQ is for sale from Raw State Audio
