Mono Class A discrete 4-band 500 series EQ module
An EQ As Versatile As It Is Unique
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.
Driving the Output Circuit for More Tone Shaping
Phoenix Audio’s renown DSOP-2 output amplifier, with its custom-wound transformer, is able to deliver everything from ultra-clean signals with abundant headroom to fat, fully saturated tones. By driving the output attenuator, one can drive the DSOP-2 output stage for a wide variety of lush, Class-A saturation. Many engineers even use the Gyrator EQ completely flat in order to simply add the musicality of our proprietary amplifier circuits.
Versatile And Effortless, Day After Day
The Gyrator EQ is a powerfully versatile, high-quality studio tool. Unlike many Class-A EQs that just do “their thing” due to inherent distortion characteristics, the Gyrator EQ keeps the input signal clean, making it possible for the engineer to keep tones transparent or saturate them to taste. Importantly, doing so is effortless and intuitive due to the DRS Gyrator’s straight-forward design and unerring musicality. Those who own this EQ tell us that it quickly becomes their “go to EQ”—used effortlessly every day across a vast variety of instruments, voices and full mixes.
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.

I have had a Rupert Neve 500 series 551 inductor EQ for comparison, and the Phoenix Audio Gyrator is more versatile with a bigger sound if desired. It's nice to have the versatility that the amplified output transformer gives. If you have, say, an SSL 6 Pre, which I don't, you can give that kind of preamp a thickness by running it through the EQ and keeping the EQ flat, but increasing the output stage. That is a huge benefit! I use it in conjunction with some API and 1073 style pres and mix in a little magic from this output stage. Concerning the EQ, it's extremely versatile, but more subtle than say an API EQ, though you can get into some unwanted harshness in the mid hi frequency range if you push the level of that range too much. You can also get some hissing from going way too high on the 10k, 15k & 25k shelving settings. I would say it's much harder to make mistakes like this with this EQ than with an API EQ. You have to be aware of these thresholds and shape within the good area. Your ears will tell you, and the problem areas exist on the outside extreme. The control of low frequency is outstanding, with plenty of options in the right places, like 40Hz, 80Hz and 130Hz. For example, you can cut out lows in vocals, acoustic guitars and boost on drums and bass. Overall, with this EQ, I find myself adding frequency content in a way that isn't overdone. It's easier to use and sweeter than most EQs. I use a lot of plugin EQs and have for the last 14 years. My preamps and mics typically come close to nailing the sound I'm after. And this EQ shapes the last 10%. It helps the compression stage with a better balance so that the compressor isn't grabbing low frequencies or peaky mid high frequencies. The versatility, forgiving nature and the amplified output transformer impressed me enough to get a second one. It's all you really need, but if you're a gear junky, you'll get something else as well!
