Aurora Audio GTQ2 Class A Stereo Microphone Preamp with 3-Band EQ
The original Mic Pre / EQ that set the Standard for Aurora's Class-A discrete circuit designs.
The Aurora GTQ2 is a Stereo Microphone Preamp with a 3-Band EQ and Class-A discrete balanced transformer Input and Output.
GTQ3 features adjustable input impedance coupled with 80dB of available gain that makes the GTQ2 ideal for cleanly amplifying everything: low power ribbon mics, classic dynamic mics, and high output condensers. You don’t always have to stay clean though. Turn up the gain on the GTQ2 and hear the classic harmonics and overtones that made the Class A British sound so sought after.
The GTQ2 EQ is made to be engineer and musician friendly. This 3 band small wonder is an incredibly powerful tone shaping tool. Geoff saw the opportunity to simplify the EQ section by focusing on the most musical frequencies so you can spend your time recording and not twiddling knobs. The Hi end shelving at 12K provides air and sheen while never getting thin or shrill. The Low end shelving at 80hz gives you enough power to fill out an anemic sound or cut to get rid of any offending rumble. The Midrange control at 400Hz, 1.6K, and 3.2K can help you get rid of mud and get tracks to cut though your dense mix.
When is a DI not just a DI? When it’s the GTQ2 DI! The 10 Megohm DI input allows for a full frequency experience. You will hear Bass and Keyboards with a whole new sense of clarity and fullness. For those recording instruments “in the box” like electric guitars, amp and room simulations will sound more real than ever since the GTQ2 provides an unparalleled source material for the modeling program to react to.
The GTQ2 is truly an all-purpose mic pre. Ideal for any instrument, vocal, or sound effect, the GTQ2 is being used around the world by professionals in Music, Film, and TV.
Since it’s introduction to the pro audio world over 10 years ago by Geoff Tanner, the GTQ2 has become a modern classic. With one foot firmly planted in the historic British preamp sound that makes up some of the worlds favorite recordings of all time, the GTQ2 is also equally capable of capturing the best modern tones of today. It is the foundation of the entire Aurora Audio line and sets the standard for all of the Class A discrete designs for the company.
Geoff Tanner’s design incorporates balanced transformer input and output. The transformers are made to Geoff’s exacting specifications by the old Marinair crew in the United Kingdom. This results in the warm yet extremely punchy sound that only great iron can provide.
