In the mid-1980s, Sir George Martin commissioned legendary console designer Rupert Neve to build a series of innovative, no-compromise console modules for AIR Studios. These modules were hugely successful, and formed the base of Focusrite studio consoles, widely regarded as the best-sounding analogue recording consoles of all time. Today, derivatives of these modules are used in the world's top studios, and the sought-after Focusrite Heritage Sound is at the heart of thousands of hit records. Today's Focusrite ISA series brings classic Focusrite sound to your studio or live performance.
Featuring a portable, rugged chassis, ISA One combines Focusrite classic mic preamp with a flexible, independent DI channel and optional precision 192kHz A/D conversion.
At the heart of the ISA series is the Lundahl mic preamp and matching input transformer – essentially the same circuitry based on the original ISA110 that has been used in all Focusrite designs for 30 years. The input transformer imparts a special character to the sound that cannot be emulated in any other way: inseparable from the microphone itself, the transformer input stage is ideal for use with classic microphones. But unlike the original design, this mic pre has a special feature that makes it much more versatile: 4 carefully selected impedances allow you to match an input microphone in different ways. You can bring out the character of a classic microphone or emphasise a particular characteristic, or get a completely transparent modern sound – the choice is yours.
Whether you're a musician, engineer, or producer, you'll appreciate the versatility of ISA One, with its front-panel DI input. The DI channel includes a low/high impedance switch and amplifier output, separate power supply for the optional A/D converter, and separate XLR output on the rear panel.
3-year warranty on all new Focusrite products purchased from 1 January 2018 onwards. The Focusrite Warranty is synonymous with peace of mind for the user, represents a professional service, which minimizes waiting times in the event of a manufacturing defect, and confirms that the products of the English company are built respecting high quality standards.
MAIN FEATURES
ISA Series Transformer Based Preamplifier
Housed in a robust, portable chassis, ISA One delivers classic Focusrite mic preamp performance in a highly affordable and flexible format.
Flexible and independent DI channel
ISA One is ideal for both demanding engineers and artists, thanks to its independent gain control, an output for connection to an amplifier, an independent XLR output on the rear and routing to the optional AD converter.
Selectable impedance
Choose from 4 carefully selected impedances, including the original ISA110 setting, to get the best out of each microphone.
Headphone output with volume control
ISA One can feed the sum of the two inputs to the headphone output, or to an external stereo cue mix (such as a stereo signal from an interface) via 2 TRS jack inputs on the rear of the unit.
Dedicated insert points
They allow you to insert external processors such as an EQ or compressor between the preamp, or DI, and the optional converter.
Optional 192kHz stereo AD converter
You can choose to upgrade the unit with an optional digital card that delivers best-in-class AD performance, with a dynamic range of 118dB.
