The Focusrite ISA Two features two channels of Focusrite's classic transformer-based premium microphone preamplification; our cornerstone design which has contributed to the signature sound of many hit records across the past four decades. Each channel has balanced insert points, variable high-pass filter, and of course the now customary variable input impedance allowing you to get the very best results from any microphone.
