My ISA 220 arrived today. It does more stuff than my Red 7, and is replacing it. The ISA is part of the "ISA" range, with blue front panels. Focusrite makes several ranges, the Red Range, which is great sounding with nicer front panels and knobs, the Blue Range, which is strictly mastering gear, the ISA Range, which uses the Red Range electronics, but has more features and isn't as pretty, and the Platinum Range, which is designed for project studios at a lower price point. So here's the rundown: -Mic Preamp, true transformer balanced operation, identical to Red Series -Line Preamp, same as Red Series -Instrument Preamp (direct box) -True Class A operation with discrete transistors -Rupert Neve-designed EQ with high and lowpass filters, parametric EQ, and shelving EQ, each switchable into or out of the circuit, and either pre-compression or post-compression -Compressor -Limiter -De-esser -24/96 Digital I/O (stereo, in case you want to use its converters for a stereo mix, and user-upgradeable) So, all this stuff, and of course, it arrived the day AFTER I had two vocal recording sessions. LOL. Figures. I'll try it with acoustic guitars until my next vocal session. However, I'm pretty confident I'll like it based on how I feel about the Red 7, which incorporates the same mic preamp and compression circuit. I wasn't surprised to hear that the ISA 220 is the mic pre/dynamics box used on the new Sting record with Blue mics. I feel that for some reason, the Blue products match up well with this preamp circuit. But I was surprised to find out that they also used it as their direct box of choice for Sting's bass, so that's something I really want to check out. And I have a bass session coming up on Tuesday!
