Critic Reviews

Focusrite: ISA 428 Pre Pack | Tape Op Magazine | Longform candid interviews with music producers and audio engineers covering mixing, mastering, recording and music production.

tapeop.com

The Focusrite ISA 428 Pre Pack impresses with its four high-quality mic preamps, offering clear, balanced, and detailed sound across various instruments and vocals. The inclusion of handy features like a variable high-pass filter and switchable impedance settings adds versatility, making it easier to tailor sounds at the source. However, the preamps seem less appealing when pushed, sounding "hard," and there's a lack of information on the optional A/D conversion due to missing cables. Despite this, its performance outshines modest setups, making it a valuable addition to any studio.

Used on A Thousand Kisses Deep, as stated by recording engineer Joe Chicarelli in this December 1, 2003 Electronic Musician interview.

I primarily used 1073 and 1095 Neves on the keyboards, acoustic bass, and guitars. I also used Brent Averill 312 API preamps and the new Focusrite 428 — the one with the meters. It's a 4-channel preamp that's reminiscent of the sound of the old Focusrite 110s. I used that some of the time on trumpet, background vocals, guitar, and a lot on the acoustic piano.
