Full DescriptionView Full Description
The ISA microphone pre-amplifier was first introduced back in 1985. This transformer-based pre-amplifier formed the first half of the ISA110 mic-pre and EQ module on Focusrite's critically acclaimed Forte console. This console, and the later Studio console were hailed by many as the finest sounding consoles ever built.
The preamp 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.
A variable impedance circuit has been added, allowing the user to switch between four carefully selected input impedance settings. In addition to the original ISA110 impedance, three further impedance settings allow perfect matching, or creative mismatching of the preamp with any microphone. ISA One also features an insert point, should the need arise to place extra processing between the preamp 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 in the form of 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 utilise all the same reference points as Avid's Pro Tools HD system, allowing effortless line-up.
ISA One's headphone output features a dedicated volume control, which delivers an external stereo cue mix (a simple click track or a stereo mix feed from an interface or a live console) fed to the headphones via two TRS jack inputs on the rear of the unit.
The ISA One is also available with a state-of-the-art A-D converter. Please see - Focusrite ISA One Classic Pre-Amp with Digital A/D Card
