Focusrite ISA One - microphone preamplifier

The Focusrite ISA One is a transformer-based mic preamplifier. Its input transformer imparts a special character to the sound that can't be truly emulated in any other way. Four carefully selected impedances allow you to match microphone to input in different ways. Bring out the character of a classic mic or emphasize a special feature, or go for a totally transparent, modern sound - it's up to you.
