Description
The Aurora Audio GT4-2 Dual Channel 4-Band Equalizer features 30 selectable frequencies ranging from 33Hz to 15K. As expected, the GT4-2 is Class A discrete and features balanced transformer input and output. The transformers are made in the United Kingdom to Geoff Tanner's exacting specifications by the old Marinar crew.
Geoff's design takes that classic British EQ sound that we all know and love and expands its usability by adding some of his own touches. Let's look at the high and low end shelving. There are two gain modes to choose from. The low gain mode gives that feel of classic EQ shelving, 8dB of boost and cut. The high gain mode gives the user 18dB for grand adjustments.
The mid-range is where any EQ can show its true power. The mid-range frequencies feature THREE selectable bandwidth options to choose from. The widest curve gives you the most vintage style sound, while the narrower options enable you to get more surgical.
The GT4-2 is a powerhouse EQ that combines the best of Geoff Tanner's designs and Class A discrete technology. The result is a sound that sets it apart from any four band equalizer that has come before it.
