Focusrite ISA Two 2-Channel Rack Preamp


Focusrite’s ISA Two unites a pair of totally independent classic ISA microphone preamps from the original ISA 110 module, resulting in a combination of the best of traditional solid-state electronics with the original input transformer specified by Rupert Neve - the Lundahl LL1538.

 

Inputs and Gain

On ISA Two each mic pre has the option of mic, line or the front-panel instrument input, with variable input impedance to ensure that you’re getting the very best performance from the source. Up to 60dB of gain is available on the first four-position rotatory and gain range switches, with a further +20dB of continuously variable trim. Resulting in a huge 80dB of gain still being available should it be required.

 

LED Meters & Rear-Panel

The high-pass filter on the ISA Two features variable cut-off frequency between 16Hz and 420kHz. While a pair of 8-segment LED meters to show peak signal level in dBFS and a rear-panel pot allows calibration to suit you’re A-D converters. Lastly, rear-panel insert points allow the use of inline processors such as compression.

 

3-Year Warranty

With all Focusrite products, you’ll benefit from a 3-year warranty, and award-winning customer support.
