Modern version of the iconic transformer-based ISA 110 preamp module designed by Mr. Rupert Neve for Sir George Martin’s AIR studios.
ISA Two is the latest addition to the well-established ISA Series from Focusrite. Featuring two transformer-based mic pres, ISA Two is ideal for those making high-quality stereo recordings.
Focusrite’s prestigious ISA (Input Signal Amplifier) microphone preamplifiers have contributed to the signature sound of many hit records across the past four decades. Indeed, you’ll find Focusrite ISA Series products adorning the racks of many professional studios worldwide.
ISA Two features up to 80 dB of low-noise gain as well as variable input impedance, allowing you to get the best from any type of microphone. In addition to the microphone inputs, transparent DI inputs with front panel access and rear panel TRS line inputs are provided, making ISA Two the ideal premium dual channel front-end to your DAW.
Each channel has a variable cut-off high-pass filter, the design of which has remained unchanged since its introduction in the first ISA 110 module during the 1980’s. With attenuation of 18 dB/Octave the filter has a variable cut-off frequency of 16 to 420 Hz – easily controlled with the large dial on the front panel. In addition to the filter, each channel has phantom power, phase-invert and a rear panel insert. Each of these features can be switched in and out via the front panel.
Finally, a meter is available for each channel. Eight-segment LED arrays clearly display the level of your two signals. By using the calibration knob on the rear panel, you can line up your analogue levels with your converters or DAW. You will be safe in the knowledge that clipping has been avoided on the way in.
Quintessentially British, the sonic integrity of the ISA Series is very highly regarded. Until now, this classic design was only available in one, four and eight channel variants. ISA Two completes the series.
