Focusrite ISA One Classic Analogue Microphone Pre-Amplifier

At the heart of the ISA range is the microphone preamplifier with its Lundahl input transformer — essentially the same circuit, based on the original ISA110, that has been used for 30 years in successive Focusrite designs. The input transformer imparts a special character to the sound that can't be truly emulated in any other way.
