  • Parametric peaking MID band with ±10dB of cut/boost, fixed Q and harmonic saturation.

  • LO, MID, and HI LED indicators to display saturation level.

  • ±20dB Input and Output Level for dense harmonic saturation or clean EQ effects.

  • Stereo, Dual Mono & Mid/Side operation.

  • Bypassable Hi & Lo Cut controls per channel.

HarmonicEQ® Evolution

Carnaby HE2 is a 2u 19-Inch rack stereo 3-band parametric EQ – an evolution of our Carnaby 500.

Carnaby HE2 HarmonicEQ® utilises the same unique and revolutionary EQ concept found in Carnaby 500, using harmonic saturation to boost and cut frequency content. Enhance your sources, stems and mixes with genuine analogue harmonic saturation with the feel, familiarity, and control of an equaliser. Explore how we take this concept even further.

2-channel HarmonicEQ® + Much More

Whether being used for Stereo, Dual Mono or Mid-Side processing, Carnaby HE2 features 3 bypassable, interactive bands of HarmonicEQ® per channel. Each band has 10dB of boost/cut and its own sweepable and overlapping frequency controls. As with Carnaby 500, each of Carnaby HE2s bands has a unique blend of harmonic content suited to its frequency band to achieve maximum musicality.

HI Band
The HI band has a frequency range from 5kHz all the way to 25kHz and uses smooth saturation to naturally extend high frequencies beyond the audio band for ultimate air and breath on vocals and acoustic instruments.

MID Band
The MID band is a peaking filter with a fixed Q and a wide sweepable frequency range from 200Hz up to 6.2kHz. It uses saturation to add harmonic emphasis to the source anywhere in the frequency range.

LO Band
The LO band has a frequency range of 420Hz down to 20Hz and uses hard-clipping saturation to extend sub-harmonic frequencies into the audible low-end - perfect for subtle low-end warming or extreme sub-harmonic saturation.

Dynamic Response
Unlike other EQs, Carnaby HE2 has a dynamic response and increases in total boost/cut and harmonics as the circuits are driven harder. An Input and Output level control on each band allows for ±20dB of level adjustment, enabling you to drive Carnaby HE2 harder with the input control for more saturation and distortion effects, or back it off for a cleaner EQ when needed.

Fully Digitally-Controlled with USB and Network options

Carnaby HE2 takes control to a whole new level allowing all buttons and controls of the unit to be controlled remotely via USB or an Ethernet network. Carnaby HE2 Control seamlessly integrates with the Carnaby HE2 hardware via the USB or NET ports, allowing for convenient real-time control and recall from within your DAW. It also facilitates the independent saving and loading of presets.

Mid/Side Processing

Especially valuable for mastering, mixing, and sound design applications, Carnaby HE2 allows for Mid/Side processing, allowing you to apply HarmonicEQ® to the separate mid (center) and side (stereo width) components of your stereo signal. No additional hardware is needed, Carnaby HE2 takes care of all the necessary encoding and decoding.

Inserts for outboard hardware

Carnaby HE2 features a bypassable TRS Insert on each of its two channels. The inserts are post M/S encoding and pre M/S decoding allowing you to use each of these Inserts to connect outboard hardware before your signal hits the HarmonicEQ® processing.

Cranborne Audio Media Reviews

“A radically different and musically effective approach to analogue EQ.”

“This genuinely new, innovative design delivers something musically effective that’s truly different from conventional EQs or, for that matter, harmonic enhancers…”

“Perhaps not surprisingly, almost everything sounded bigger, ‘phatter’, and with more airy sheen…”
