The Phoenix Audio Gyrator EQ 500 is a highly versatile four-band inductor-style EQ. Modeled after the DRS EQ 500, the Gyrator features all new selectable frequency positions and a dedicated “sheen” control for boosting frequencies at 25 kHz. Equipped with a 24 V power supply, the Gyrator EQ delivers the same powerful sound as full-sized Phoenix Audio processors in a compact 500 series module.
Originally introduced in the 1970s, gyrator EQs were known for their highly musical sound. Similar to active inductor designs from Neve and API, gyrator EQs feature a proportional bandwidth that narrows as the gain is increased. However, vintage gyrator EQs tended to be big, heavy, and noisy. The Phoenix Audio Gyrator EQ 500 utilizes a solid-state design that not only solves these issues, but also improves upon the original design.
FOUR-BAND FIXED DESIGN
Equipped with four bands, each with three selectable frequencies, the Gyrator EQ 500 is incredibly easy to use. The low band extends all the way down to 40 Hz for rich, booming lows. A switchable high-pass filter can be used to created unique Pultec-style EQ curves. Two mid bands are perfect for cutting muddiness in the low-mids, adding bark and bite to tracks, or taming harshness. The high band features a dedicated “sheen” control fixed at 25 kHz for adding presence to tracks—perfect for breathing new life into acoustic instruments.
Like all of Phoenix Audio’s 500 series modules, the Gyrator EQ 500 is equipped with a 24 V step-up transformer to provide the true sound quality of the design without being limited by the 16 V Lunchbox design. This also enables the Gyrator EQ to deliver authentic analog saturation. At low levels, the Gyrator offers an ultra-clean, transparent sound, but crank up the dials to drive the output stage for fat, fully saturated tones.
2 formats: Gyrator/500 Gyrator EQ 500: mono 500 series without Preamp/DI (operates at 24 V); Ascent Two EQ Gyrator EQ with Preamp/DI: Stereo 1RU with our Ascent Series Preamp/DI; Ascent One EQ Gyrator EQ with Preamp/DI: Mono 1/2RU with our Ascent Series Preamp/DI
EQ Cut/Boost Levels: 16 dB 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 +15 db of additional gain even while the EQ is in bypass, allowing the output fader to be used to drive the output stage & transformer to color & saturate your sound, again even when the EQ is in bypass
Phoenix Audio's Class-A DSOP-2 Output Amplifier with custom-wound transformer
24 V built PSU so you can feel the sound of the 'true' unit and not be limited by the limitations of running at 16v which is the standard Lunchbox voltage
Although they originally formed in 1996 as the UK’s leading service provider for vintage consoles, Phoenix Audio is now known for crafting boutique-grade signal processors. From their DRS and Ascent series preamps, Nicerizer summing mixers and EQs to the new Gyrator 500 series module, Phoenix Audio has a reputation for creating one-of-a-kind designs.
We recently had the pleasure of sitting down with Robin Ashley, the company’s President, to learn about what Phoenix Audio is currently working on. Read on to learn about their design philosophy, their signature sound, and what Phoenix Audio has in store for the future. Continue reading →
The 500 Series format consists of a whole slew of different signal processing modules in a compact rack unit. Mic preamps, equalizers, compressors, DI boxes, filters, effects... You name it, you can find it in a 500 Series version from a wide variety of manufacturers.Most of those manufacturers participate in the VPR Alliance, established to set standards for the format to ensure that the end user can rely on consistent specifications with regard to voltage, current draw, size, etc. along with proper compatibility with existing modules. The essence of this idea is to make it simple for the user to mix and match modules from different makers, thus allowing for the broadest range of implementation for their products.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!
I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!
In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.
This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.
Thank you so much! Vintage King has been so fair and easy to work with. I can't thank you enough. It feels good to trust such a hefty purchase to folks who are so helpful and knowledgeable. Vintage King is a sound designers dream store.
You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!
I would recommend Vintage King to any one looking for top-class gear, unbeatable customer service and the best prices on the map!
My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
Thanks for your great service and getting this out today. You guys really are the Kings!
Better than expected! Truly impeccable service. Your team was professional, knowledgeable, provided speedy delivery above and beyond standard. Vintage King Audio is definitely my go to for all of my audio and information needs.
