How to choose
Choose based on how many channels you need to record at once and whether you need digital output.
Beginner
Someone recording one source at a time, such as a vocal or an acoustic instrument, will find the ISA One simple to place between a microphone and an interface. Start with the gain low and bring it up while watching your interface meters to avoid clipping.
Intermediate
A home or project studio tracking a small band or drum kit benefits from the ISA 428 MkII, which gives four channels of the same preamp sound in one box. Label your channels and keep gain staging consistent across the unit so mixed sources sit evenly.
Expert
A professional studio running larger sessions can use the ISA 828 for eight channels and add the ISA 428/828 A/D card to send those channels straight into a digital rig. Keep the unit properly earthed and maintain its connectors, since it is likely to see daily use across many sessions.

About Focusrite in Studio Preamps
Focusrite built its reputation on the ISA preamp circuit, prized for a clean, open sound that works on vocals, instruments and full bands. People buy into the ISA range because the same core circuit scales from a single desktop unit up to a full multi-channel rack.
This page has the single-channel ISA One, the multi-channel ISA 428 MkII and ISA 828, plus the A/D card that adds digital conversion to the 428/828 chassis.
