The Focusrite ISA Two mic preamp gives you the sonic essence of the legendary Forte and Studio consoles in a single rack unit chassis. You get two channels, with inputs for microphone, line-level, and direct instrument-level sources. A variable impedance selector also lets you dial in the warmth you want without sacrificing clarity.
The ISA Two's DI and microphone inputs run in parallel, so you can blend the direct signal of the instrument with the sound of the miked up amplifier - a killer trick for getting bass sounds that are both fat and punchy. If warmth, transparency, and useful features are on your preamp wishlist, check out the Focusrite ISA Two.
