A variable impedance selector allows you to dial in the desired warmth without compromising clarity. If you're in search of warmth, transparency, and essential features in a preamp, the Focusrite ISA Two is the one to consider. A Heritage of Excellence With a distinguished heritage dating back to its introduction in 1985, the transformer-based Focusrite preamp has achieved legendary status and set a benchmark for transparency. However, what sets it apart is the subtle warmth resulting from transformer core saturation. This unique combination of warmth and transparent, open high frequencies gives the Focusrite preamp its distinctive "sound" that remains sought after in top studios worldwide. Engineering Innovations for Superior Sound The Focusrite ISA Two incorporates innovative engineering to deliver a superior-sounding mic preamp. It operates over a wide range (10Hz-135kHz) to eliminate the audible rolloff exhibited by preamps limited to the audible bandwidth. Enjoy up to 80dB of undistorted gain with the ISA topology. Additionally, variable input impedance enables you to fine-tune the "character" of your signal, from pristine transparency to vintage warmth. Timeless Components Rupert Neve personally selected the Lundahl LL1538 as the input transformer for the legendary Focusrite ISA 110, and it continues to be the best microphone input transformer available. Every ISA Series mic pre from Focusrite features the Lundahl LL1538 for its exceptional quality. The ISA circuit incorporates Mr. Neve's perfected Zobel network, contributing to the broad-bandwidth and ruler-flat frequency response exhibited by ISA preamps.
