Phoenix Audio Gyrator 500: Musical and Controlled Analog EQ

Introduction

The Phoenix Audio Gyrator EQ/500 is a 500-format module inspired by the Gyrator circuits of the 1970s. It is distinguished by its musical and transparent sound, perfect for those looking for an equalizer with a controlled character but capable of adding air, body, and presence in a refined way.

Controls and Bands

This module offers 4 active EQ bands and an 80 Hz high-pass filter (12 dB/oct), with 21-position step controls and ±16 dB range for each band:

• Low (shelving): selectable between 40, 80 and 130 Hz
• Low-Mid (bell): 200, 400 and 800 Hz
• High-Mid(bell): 1.6, 3 and 6 kHz
• High (shelving): 10, 15 and 25 kHz

This configuration allows musical and precise intervention on all instruments, from vocals to bass, from drums to solo instruments, without ever being intrusive or excessive.

Construction and Sound Character

The circuit is designed for a very linear response, but the Class A output stage with DSOP2 transformer can introduce slight harmonic saturation when pushed, enriching the sound with a warm, natural character.

Unlike heavily colored EQs such as Neve or Pultec-style, the Gyrator 500 focuses on transparent musicality, with a sound that remains controlled even with major boosts.

Conclusions

The Phoenix Audio Gyrator EQ/500 is a versatile, elegant, and highly musical equalizer. It is ideal for those who want control, precision, and an analog touch without exaggeration. Perfect in any studio working with the 500 format and wanting a reliable EQ to rely on every day.
