Focusrite ISA One · Microphone Preamp

The ISA One is based on the awarded ISA transformator. It is built in a robust, portable chassis at a unbelievable price. The ISA One connects classic vintage microphone pre-amps from the original module ISA110 with the Lundahl L1538 transformator.

The pre-amp is expanded by a line-input (XLR & TRS), an independent D.I. channel with assignable gain, active or passive impedence switch, a chinch output for the amp routing as well as a rear, independent XLR output.

The flexible, independent direct-input makes the ISA One ideal for sound engineers who want to mix microphone guitar signals and for ambitious artists who are looking for a classic solution for guitars and vocals.

A circuit with adjustable resistance enables the user to choose between four input-sensitivities. Additionaly to the original ISA110 impedance three more adjustments are possible for perfect adaption with every microphone.

The function "phantom power", "phase return" and a 75 Hz, 18 dB/octave high-pass filter can be operated through the front panel.

Channel independent double VU metres with variable sensitivity enable exact dissemination of analogue and digital sources and there is a 2 x 6 LED peak metre. The VU metre can either show the pre- or the post signal.

The headphone output of the ISA One has an own volume control which can be mixed with an extern stereo.

Optionally a state-of-the-art, stereo A-D converter is available. This optional card can be refitted at any time and offers high-quality converters with 24 bit/192 kHz in a dynamic area of 119 dB.

  • Single Channel Original ISA Series Pre Amp in a portable metal Chassis

  • Direct Instrument inputs including high and low impedance options to provide a comprehensive DI solution
  • VU meter and Ladder LEDs metering at source
  • Cue mix stereo inputs
