ISA One is a single-channel mic preamp boasting classic topology from Focusrite's legendary ISA110 module, with a line input (XLR and TRS) and an independent D.I. channel for blending signals. It also offers dedicated gain control, active or passive impedance switch, a TRS output for routing to an amp and an independent XLR output on the rear.
Other useful features include a variable impedance circuit that lets you switch between four input impedance settings, phantom power, phase reverse, a high pass filter, independent input metering and a headphone out with dedicated volume control.
