USB 2.0 audio interface with 8 Focusrite mic preamps.

The Focusrite 18i20 brings the recording performance of 8 award-winning Focusrite mic preamps and combines them with a high-quality 24-bit/96kHz USB 2.0 interface that's compatible with Mac, Windows, and iOS platforms, which means legendary recording performance on the iPad (Apple Camera Connection Kit required). Focusrite's mic preamps are found in the world's top studios and give the 18i20 an unequalled level of performance, with low noise, minimal distortion and enormous dynamic range. The Scarlett preamps offer exceptional headroom, and two front-panel inputs also offer 10dB pad buttons to handle the highest-level inputs without distortion.

Comprehensive inputs/outputs
With 18 inputs and 20 outputs, Scarlett 18i20 includes enough I/O to handle the vast majority of day-to-day studio tasks at maximum quality, with maximum flexibility. Scarlett 18i20 features six combo XLR/jack mic/line inputs plus two front-panel XLR/jack mic/line/instrument inputs with 10dB pad buttons, 10 analogue line outputs, two independent headphone outputs on the front panel, and ADAT and S/PDIF digital I/O, plus MIDI I/O and Word Clock out for digital synchronization when required.

The ADAT interface can be used to bring in digital sources or to add extra preamps such as Focusrite's OctoPre Mk II, bringing the mic pre complement to 16 channels, ideal for recording a complete band and minimizing overdubs.

High channel count and Focusrite quality - now on USB 2.0 and iOS
Scarlett 18i20 is the USB complement of the tried and tested Saffire PRO 40 Firewire interface. Suitable for Windows, Mac and even iOS (with the Camera Connection Kit*) platforms, Scarlett 18i20's USB 2.0 connection suits almost any computer, helping you build a setup in which external storage and audio interfaces do not have to share the same computer bus (recommended for the best performance) - if you have Firewire drives, for example, a USB audio interface is the best choice.

Comprehensive bundle of included software
Comes with Ableton Live Lite - ground-breaking production and performance software, Scarlett Plug-in Suite - EQ, compression, gating and reverb, Novation Bass Station - software model of the classic Novation analogue mono-synth, and 1GB of Loopmasters samples.

Note: Includes the Focusrite Red 2 and Red 3 Plug-In Suite (AAX/AU/VST) upon registration of interface. Accurately modeled on the classic Red 2 EQ and Red 3 Compressor, the Red plug-ins let you exploit the sound of the hardware originals, conveniently from within Pro Tools (10 and above) and other audio software.

    Comments about Focusrite Scarlett 18i20 Audio Interface:

    I switch to this from a Motu Ultralite Mk3 Hybrid because I was not happy with the preamps, conversion, and not enough I/O. This is the top entry level audio interface you can buy in this price range. You get the ability to expand it with the included ADAT, Word clock, and Spdif options. You can add a Octo-Pre for an additional 8 channels which gives you 16 channels of mic inputs. There is room for outboard pres and other gear you have too. Now the sound quality is awesome for what you get. If you like a nice rounded low end and tight detailed mids, and tight high end then this is the right interface and preamp option for you. You won't have to worry about the preamps sounding thin in this unit cause they are FULL in a good way. The AD/DA conversion in this unit is better than ANY lower end interface on the market and will rival mid range interfaces and IMHO better than what I was getting in the Motu. The plugin software that you have to download is really nice especially the compressor! The drivers are very solid, just install them and forget it. I have not had one blue screen of death since I got mine in April. Overall, this is the best you can get at this price or less with all the options that you get. I almost forgot the two headphone outputs which is a plus! I would say if you are looking at this unit stop now and go BUY it cause it is worth at least a few hundred more than what it is selling for.
