Focusrite ISA One inneholder klassisk ISA mikrofon pre-amp og separat DI.
The Focusrite ISA One microphone preamplifier delivers Focusrite´s prestigious
ISA transformer-based preamp in a rugged and portable chassis, at a
ground-breaking price.
The ISA microphone pre-amplifier was first introduced back in 1985.
This transformer-based pre-amplifier formed the first half of the ISA110 mic-pre
and EQ module on Focusrite´s critically acclaimed Forte console.
This console, and the later Studio console were hailed by many as the finest
sounding consoles ever built.
