A very rare and one of the finest mic preamps ever designed — the Focusrite ISA 115HD was designed by Rupert Neve upon a request from the great George Martin and became the core of the legendary Focusrite Studio Console: the 115HD remains a benchmark of transparency, headroom, and musical warmth.

This is not just a preamp or an eq; it’s a staple of recording history. Its transformer-balanced input stage and pristine circuitry capture every nuance of performance with stunning realism. The sonic depth and smooth top end make it a favorite for vocals, strings, and acoustic instruments.

This unit has been in our studios since the start, in pretty good condition and fully tested.

Technical Highlights: Discrete Class A design with Lundahl input transformers Mic/Line inputs with variable impedance Sweepable high-pass filter and insert points 48V phantom power, phase reverse, and high-headroom output Balanced XLR and TRS I/O The same circuit topology as the legendary Focusrite Forte Console
