Phoenix Audio Gyrator 500 EQ 500-Series Module

Phoenix Audio’s Gyrator EQ is one of today’s most unique and musical EQs, allowing an incredible variety of sounds useful for everything from clean high-headroom mix buss tone shaping to deep frequency carving to smooth Class-A circuit saturation. Available either as a mono 500-series module (running at 24v) or coupled to two of our remarkable Class-A Ascent Mic Preamp/DIs in a stereo 1RU unit, the Gyrator EQ is as powerful as it is fun to use.

4-Bands of Gyration

The Gyrator EQ was first developed during what most consider the golden age of solid-state analog audio design: the 1970s. Originally designed to emulate the characteristics of an active inductor EQ (think Neve, API), the Gyrator EQ uses a rather clever combination of an amplifier, resistors and capacitors to accomplish incredibly smooth and musical frequency modifications. The modern-day Phoenix DRS Gyrator EQ gives you High, High-Mid, Low-Mid and Low frequency bands, each notched to proven frequencies from a shimmering 15kHz on down to a thumping 40Hz. There’s also a high pass filter at 80Hz, which can eliminate rumble or be used “against” low-end boosts for an extra range of unique EQ curves (think: Pultec). Even at extreme boosts and cuts, the Gyrator EQ’s uniquely musical filters maintain the core quality of your original signal, allowing you to make bold, gut-level EQ moves that won’t sound harsh, slurred or out of phase. Used more subtly, these four filters are capable of highly coherent tone shaping suitable for full mixes and mastering.

Sheen Control

Sheen control adds a beautiful breath and presense to vocals and instruments which need to come to life, with 16db control this gives great flexibility & power to really boost this or to cut if unwanted HF is present.

Features:

- 4 Bands of Gyrator EQ + High-Pass Filter

- High – 25K (sheen) 15K, 10K, (shelving EQ)

- Hi Mid – 6K, 3K, 1K6 (Bell curve EQ)

- Low Mid – 800Hz, 400Hz, 200Hz (Bell curve EQ)

- Low – 130Hz, 80Hz, 40Hz (shelving EQ)

- High Pass Filter at 80Hz, 12dB/octave

- EQ Cut/Boost Levels - 16dB Cut/Boost Per Band

- All EQ bands are stepped/detented to 21 positions for easy recall & - stereo operations for mastering or the mix bus.

- Gyrator-EQ/500 has an overall stepped output level with +15db of additional gain even while the EQ is in bypass, allowing the output fader to be used to drive the output stage & transformer to colour & saturate - your sound, again even when the EQ is in bypass.

- Phoenix Audio’s Class-A DSOP-2 Output Amplifier with custom-wound transformer.

- 24v built PSU so you can feel the sound of the ‘true’ unit and not be limited by the limitions of running at 16v which is the standard Lunchbox voltage.
