We've left this page up for reference only. Check out the great alternatives on this page or call toll-free (800) 222-4700 to speak with a Sweetwater Sales Engineer about similar products. From Our Research Team:The Multichannel Pre Pack!The ISA 428 Pre Pack is the perfect multi-channel front end for any professional DAW. Four classic Rupert Neve-designed, transformer-based preamps with switchable impedance and direct instrument inputs. An optional eight-channel 192kHz A/D converter, preceded by the all new proprietary Soft Limiter circuit, provides the perfect path into your Pro Tools HD system. The benefits of the ISA 428 Pre Pack preamp's topology include superb common-mode rejection, an excellent overload margin and, with its shared gain structure (20dB from the hand-wound transformer and up to 40dB from the amplifier), an extremely low noise floor and super-wide bandwidth (10Hz to 200kHz). This pre amp design is the cornerstone of Focusrite's signature "warm-yet-transparent" sound and the ISA 428 Pre Pack is a point of reference for any discerning audio professional.Focusrite ISA 428 Pre Pack At-a-Glance:
Variable input impedance The input stage of the ISA 428 Pre Pack provides enhanced control and creativity allowing you to switch between four carefully selected input impedance settings. The original ISA 110 setting is supplemented by three further impedance settings to either perfectly match the preamp with any microphone and maximize level, or use different settings creatively to shape the sound of the microphone being used. Should the need arise to place extra processing in between pre amp and conversion, insert points are also featured on every channel. Soft Limiter Protecting the ADC, the ISA 428's Soft Limiter opto circuit is a new design from Focusrite, entirely preventing any digital overs, while minimizing the undesirable distortion that standard limiter circuits often generate. Superb A/D conversion with optional card Finally, adding the new A/D converter to the ISA 428 Pre Pack gives you cutting-edge conversion technology, encompassed within pristine Focusrite circuitry, providing eight conversion channels of the highest quality, at frequency rates of up to 192kHz. Running at 96kHz allows for up to 16 (2 x 8, parallel) simultaneous digital outputs in addition to the four main analog outputs. Digital output options include dual AES/EBU, SPDIF and dual ADAT lightpipe. Full digital metering is provided for every channel, alongside new "moving coil" peak meters, designed to catch even the fastest of transients. Best of past and present Classic preamp technology, custom Focusrite input and limiting circuits and the very best in A/D conversion technology, the ISA 428 Pre Pack raises the bar for multi-channel recording solutions into Pro Tools HD, or any other professional DAW. Equally, it can be used as an additional set of high quality pre amps for any analogue or digital console or hard disk recorder. Focusrite ISA 428 Pre Pack Features:

Great Preamp, with the selectable impedance this is the preamp you need when your looking for versatility. Especially with transformerless mics,it brings new life to great mics.

The ISA428 is a great sounding preamp in it's own right, but coupled with the optional A/D card becomes a very flexible tool for the studio. For example, you can patch 4 additional sources into the un... read more [+]it via the A/D inputs, which means one ISA428 can deliver 8, well-converted sources to a pro tools or other DAW system. The pres on the unit themselves have tons of gain available, and have a slightly 'flattering side of neutral' character on sparkly transients for acoustic guitars (for which they are my favorite choice). Highly recommended. close [-]

If you're one of those people like me who's just looking for a quality pre-amp without all the added fuss of EQ's and compression (since with do that with plug-in's anyway now...), check out this didd... read more [+]y. September 21, 2007 Music Background: Recording engineer, drummer I've had great results with it on drums, vocals and acoustic guitar. It provides instant "fatness" when recording guitar cabs (which I like), and the variable impedence feature is always fun to try on everything. For connectivety, I have a good Mogami snake that I use to connect the pre-amp out's to the 1/4" inputs on my Mackie Onyx, which then goes straight into my PC. close [-] Sweetwater Advice
Paul AllenI've owned an ISA428 for a few years now, and it continues to be my go-to stereo mic pre. The best thing about the ISA pre is its ability to work on so many things and retain a clear, detailed, and yet warm sound that you would find on high-end single channel mic pres at this price (yet of course the ISA428 is four channels). In addition, the impedence switching comes in handy to work w/ any mic/input option, including the Royers and other ribbon mics. I mainly use it for stereo acoustic guitar recording, but it truly is a workhorse in the studio and in my mind a must-have for any multi-channel recording facility. Can't Trust Focusrite
by Adam Arfaras from Tampa, Fla.
The ISA428 is a nice preamp. I purchased mine with the intentions of upgrading by adding the card that existed at the time of purchase. It had a limiter and added quality digital outs just to name a... read more [+] few features. It cost $599. Now, the new card runs $899 and doesn't have a limiter and the older better card did but was discontinued. I emailed focusrite only to get an arrogant creep response to my complaint. Go with the alternative! close [-]
