18x8 USB 2.0 audio interface with four Focusrite preamps.

With four award-winning Focusrite preamps, the 18i8 is designed for producers and recording artist that demand a significant number of inputs to track multiple sources at the same time. The 18i8 boasts 18 separate inputs and 8 independent outputs, all housed in a rugged aluminum exterior with input controls and signal halos to keep incoming signals honest.

Focusrite: Over 25 years of audio excellence
Focusrite was commissioned to make its first ‘no-holds-barred' microphone preamps by Sir George Martin for his Air Studio facility in London. Over the following 25 years Focusrite has designed some of the finest mic preamps in the music industry, and in recent years has developed a series of best-selling audio interfaces for people who really care about sound.

18 separate inputs
At the heart of 18i8 is a set of four Focusrite mic preamps with up to 60dB gain, designed specifically for Focusrite's computer audio interfaces. The first two offer Mic/Line/Instrument on universal XLR/TRS connectors while 3 and 4 offer Mic/Line capability on universal XLRs - all four on the front panel with pads and 48V phantom power. Four more line inputs are provided on TRS connectors. An ADAT optical digital connector provides eight additional digital inputs that can also be used with external mic preamps like Focusrite's OctoPre Mk II to increase the number of mic inputs the 18i8 can handle to 12. A stereo S/PDIF coaxial input is also included.

8 independent outputs
On the output side, there are two TRS monitor outputs, stereo S/PDIF coax, and two independent stereo headphone outputs, each with their own volume knob so artist and engineer can control their own personal monitoring. All analogue inputs and outputs have their own connectors, so no breakout cables are required, and all feature Focusrite precision 24-bit, 96kHz sampling A/D and D/A conversion to get the most accurate signal possible into and out of recording applications on Windows, Mac and now iOS apps.

Tough and innovative hardware
Scarlett 18i8 is housed in a compact red unibody metal case to withstand the rigours of the road - and the studio. Input level controls feature signal halos - LED rings around the level control that give a simple and immediate go/no-go level indication: green means there is a recordable signal while red indicates overload. A large main monitor knob with mute button means that main monitor levels are always at your fingertips.

Included software
Included in the package is the Scarlett MixControl low-latency DSP-based software mixer and router, with intuitive one-click presets and a latency of under 1.4 ms. You'll also find the Scarlett plug-in suite for VST, AU and RTAS, offering EQ, gate, compression and reverb, plus Ableton Live Lite, the Novation Bass Station soft synth and a Loopmasters sample pack.

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 18i8 Audio Interface:

        Before I got this, I was using a Tascam us-1800. The Tascam is O.K. for it's price, and you get more inputs initially.

        The game changer for me was the quality of the A/D converters. recording the same sources (especially my guitars and bass direct in and amping with guitar rig 5) were very noticeably better.

        It also has a built in DSP mixer for monitoring, so I no longer needed an external mixer for zero latency monitoring. (the Tascam has that blend knob thing, but let's be real, that thing is terrible)

        the bundled VST's seem nice. So far I have only used the reverb, but it really sweetens vox nice and subtly (the way you want it)

        between buying this and a new bass guitar, my recording went from demo to pro sounding overnight (well, literally, over 2 days I had redone a song start to finish and it sounded amazing).

        no regrets on this thing at all. Mic pres are clean with lots of headroom, and the converters are top notch in the price range.

          Comments about Focusrite Scarlett 18i8 Audio Interface:

          Think twice before buying this. It's a great interface except there is a very nasty distortion present on recorded tracks when you record in 16 bit depth. I did some internet research and noticed many others had similar issues. What a letdown. I contacted Focusrite about the issue but they never got back to me. I'll probably be returning this interface...
