FOCUSRITE PRO ISA-TWO ISA - 2 channels

But an additional +20 dB of variable gain through the rotary Trim provides a "whopping" 80 dB of headroom. Enough to handle any situation.


Swiss Army Knife.

The disengageable "sliding" high-pass filter offers a variable cutoff frequency between 16 and 420 Hz. A pair of 8-segment LED indicators display the peak signal level in dBFS, while a potentiometer - located on the rear panel - allows calibration of the meters to match external AN converters. Switchable insert points on the rear panel allow the use of (line-level) processors such as compressors or equalizers. A real workhorse!
