The Cranborne Audio Carnaby 500 Equalizer is a unique 3-band parametric EQ designed for the 500 series format. It introduces a groundbreaking concept called “Harmonic EQ,” which utilizes harmonic saturation to boost and cut frequency content, providing a genuine analog harmonic saturation experience with the control of an equalizer. Here’s a detailed overview of its features:

Harmonic EQ Concept:

The Carnaby 500 is the world’s first Harmonic EQ, enhancing audio sources, stems, and mixes with analog harmonic saturation for a warm and musical sound.

3-Band Parametric EQ:

The EQ features three interactive bands, each with 10 dB of boost/cut and sweepable overlapping frequency controls.

HI Band: Covers a frequency range from 5kHz to 25kHz, adding smooth saturation to extend high frequencies for air and breath in vocals and acoustic instruments.

MID Band: A peaking filter with a fixed Q and a wide sweepable frequency range from 200 Hz to 6.2 kHz, using saturation to emphasize harmonics anywhere in the frequency range.

LO Band: With a frequency range of 420 Hz down to 20 Hz, it uses hard-clipping saturation to extend sub-harmonic frequencies into the audible low-end, suitable for subtle warming or extreme saturation.

Dynamic Response:

Unlike traditional EQs, Carnaby 500 exhibits a dynamic response, increasing total boost/cut and harmonics as you drive the circuits harder. Each band has input and output level controls with ±20 dB of adjustment, allowing for saturation and distortion effects or cleaner EQ.

Stereo-Link via OPTOSYNC:

Carnaby 500 offers an innovative stereo-linking feature called OPTOSYNC, allowing two units to work as a perfect stereo pair. OPTOSYNC synchronizes controls from the left unit to the right wirelessly using LED and optical communication. This can be used for stereo mixes or linking multiple units for broader applications.
