From Our Research Team:

Here's an Awesome Deal on a Focusrite Pre 4-pack

A 4-pack of Focusrite microphone preamplifiers has never been so affordable! Focusrite's ISA428 MkII retains all of the primary functions of the original ISA428. You get four hand-wound transformer-based preamps built around the original ISA 110 preamp circuit, housed in a convenient 2U chassis. Each of these incredible preamps features switchable impedance and an impressive 122dB of dynamic range, and each provides you with Focusrite's highly sought-after warm and transparent sound. You also get the same fantastic DI circuits found on the original ISA428, a favorite of many engineers for the bite they give electric bass. And by omitting the bulky VU meters and soft limiters, and retaining the precise LED metering of the original ISA428, Focusrite reduced the environmental footprint of the ISA428 MkII. They've also uncluttered its face and reduced its cost, all without impacting its performance. An optional A/D conversion card gives you up to eight channels of conversion over ADAT lightpipe, so the ISA428 MkII is as easy to integrate into your DAW as ever.

Focusrite ISA428 MkII 4-channel Microphone Preamplifier Features at a Glance:
  • 4 classic transformer-based preamps
  • Switchable impedance for unparalleled mic matching or extended mic creativity
  • Includes the classic ISA 110 setting
  • Multiple direct instrument inputs on the front panel
  • Analog insert points on every channel
  • Highpass filters on every channel
  • Ultra-precise LED metering (dBfs)
  • 2U chassis design
  • Optional A/D card provides 8 channels of cutting-edge conversion at up to 192kHz

The Focusrite ISA428 MkII gives you an amazing deal on four microphone preamps!

The Go to Preamp

by JohnBoy from Fredericksburg, VA

Music Background: Multi-instrumentalist, recording and mix engineer, studio owner
I got this preamp based on it's versatility and a several hours of use during my training. I almost always go to this guy for overheads and hihat sounds, the filter is useful and has great phasing. Th... read more [+]e impedance settings really allowed me to squeeze a lot sounds out of my good but modest mic collection. I recommend this pre for anyone in need of unit that will deliver multiple sounds from fewer sources. The only reason for the 4.5 is I have not tried older focusrite units, or the channel strip to compare. close [-]

Works for everything

I gave this 4.5 stars because it sounds great with anything plugged into it from any sound source or instrument. As a full time studio owner having a pre that you know will perform time and time agai... read more [+]n is extremely important. The ISA428II fills this need exceptionally well. Stacking track after track is a joy and the switchable impedance is a must have. 50 ohm mics sound great on vocals with the 600ohm setting. Too much loading for your 200ohm mics, just switch to a higher input impedance. I have other great pre's but this Rupert Neve, transformer coupled pre-amp sounds as great, and sometimes better, than a lot of others and for a great price. close [-]

One of the best values on the market

by Nick from NJ

The first thing I recorded with this guy was a drum track. 2 overheads, kick and snare were all run through the isa. Previously, i was using UA 610 pre's which sound fantastic, but never gave me the w... read more [+]ow factor on a kit. As soon as I hit playback I knew I had a winner. Big without being over colored, but not dull by any stretch. Very punchy, and balanced throughout the frequency range. Tracks i record with this take eq and compression extremely well, and it essentially makes my job much easier and enjoyable in the studio. The stepped gain knobs are pretty hot too. At this pricepoint it's a no brainer. close [-]

sounds awesome, miss the VUs

by Brian from Santa Barbara, CA

Music Background: Local Pro Musician and recording hobbyist
I would give this a 5 star since it is my favorite preamp of all time for just about anything except for the fact that this new MKii version took away one of my favorite features of my other older ISA... read more [+]428s and that is the big VU meters. Bring them back, and I'll give it 5 stars. If you don't care about the VUs, then you will find this to be the most awesome preamp for anything you can throw at it. Vocals, saxes, guitars, drums, etc...all amazing. Big but tight and controlled low end, perfect mids, awesome space and clarity in the highs. The features are good too with the filter, insert, variable impedance, etc. close [-]

Sweetwater Advice

Tim Maus
The fantastic quartet of preamps in the Focusrite ISA428 MkII has never let me down. Transparent with just the right amount of warmth to add some character, it will easily find its niche in your studio. Also FANTASTIC as an instrument DI!
