Focusrite is dedicated to bringing you the tools you need to enhance the way you work. Our products are made with pride and principle by engineers who themselves are musicians and understand the part our products play in your process. The ‘ISA One’ microphone pre-amplifier delivers Focusrite's prestigious ISA transformer-based pre-amp in a rugged and portable chassis, at a groundbreaking price. ISA One features the classic vintage microphone pre-amplifier topology from the original ISA110 module, including the Lundahl L1538 transformer and bespoke zobel network. The pre-amp is complemented by a line input and an independent D.I. channel, complete with dedicated gain control, active or passive impedance switch, a TRS Jack output for routing to an amp and an independent XLR output on the rear. This flexible independent D.I. makes the ISA One ideal both for engineers wishing to blend a D.I.’d guitar signal with a mic’d guitar cabinet, and for demanding performers who require a single classic solution for both guitar and vocals. ISA One also features an insert point, for extra processing between the pre amp or D.I. and the optional converter. Phantom power, phase reverse and a 75Hz, 18dB/octave high-pass filter are also available from the angled front fascia. Independent input metering for both channels is provided by a moving coil VU meter with variable calibration to suit analogue and digital recording media, alongside two six-LED peak meters; inputs can be metered either pre- or post-insert. The meter calibrations utilize all the same reference points as Digidesign's Pro Tools HD system, allowing effortless line-up. ISA One’s headphone output features a dedicated volume control to deliver an external stereo cue mix fed to the headphones via two TRS jack inputs on the rear of the unit. At Focusrite our focus on quality is all-consuming. All of our products are easy to use, logically designed, and give years of class-leading, top-notch performance.
