Descriptions
Geoff Tanner’s design incorporates balanced transformer input and output. Aurora’s 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. The adjustable input impedance coupled with 80 dB of available gain makes the Aurora Audio GTQ1 single-channel microphone preamp/EQ 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 GTQ1 and hear the classic harmonics and overtones that made the Class A British sound so sought after.
The equalizer section 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 80 Hz gives you enough power to fill out an anemic sound or cut to get rid of any offending rumble. The Midrange control at 400 Hz, 1.6K, and 3.2K can help you get rid of mud and get tracks to cut though your dense mix.
