The deal

What it is

Audio Gyratec X is Antelope's Synergy Core recreation of the Gyraf Audio tube stereo compressor - a Vari-Mu design drawing on technology from early limiters like the coveted Fairchild 670. It delivers genuine tube compression character with a fast, program-dependent response that works well on material ranging from drum buses to full mixes. Antelope are the first to offer a Synergy Core version of this particular hardware unit.

Who it's for

Mix engineers who want the glue and warmth of a true tube Vari-Mu compressor. It pairs naturally with other compressor types - use it alongside a faster compressor for serial or parallel processing where the Gyratec X handles the harmonic smoothing while the other unit manages transient control.

Key features

• Vari-Mu tube circuitry modeled on the Gyraf Audio hardware, with speed and behavior borrowed from early limiters like the Fairchild 670
• Smooth high-pass filtering enables heavy compression without dirtying up the low frequencies
• Available in AAX Native, AU, and VST3 formats for Mac (Apple Silicon) and Windows
• Authorized via iLok Cloud or iLok dongle, so no hardware key is needed if you use cloud licensing
