Four Mic Preamps - When two mic inputs just aren't enough
If you've been searching for an affordable, compact audio interface with four mic inputs, your search is over. The 4pre packs four mic inputs into an impressively small half-rack form factor, along with a healthy complement of additional professional-grade audio connections. Just think of the possibilities. You can record and mix vocals plus guitar for two musicians simultaneously. Or mic a drum kit with overheads and close-ups. Or record lead and background vocals in one take. With an interface this flexible, capable, and great-sounding, you'll be ready for any situation your music throws at you.
Designed to go with you anywhere
The 4pre is an impressively small 8.5 by 7 by 1.75 inches, which means that it slides easily into your backpack. It also sits nicely next to your laptop or desktop computer.
Connect guitars, a keyboard, or other inputs
The four inputs are not just for mics: they are combo jacks that also accept a quarter-inch plug. Inputs 1-2 take line-level signals, such as the output from a synth or keyboard. Inputs 3-4 are "hi-Z" DI inputs with proper impedance for plugging in your electric guitar directly, without an amp or cabinet, to process your guitar sound through amp and cab simulation plug-ins in your host software.
Hybrid technology connects to any computer
Thanks to MOTU’s Hybrid interface technology, the 4pre connects to any Mac or PC via FireWire or high-speed
USB 2.0. Connect your mic, guitar, keyboard, and digital input, and you are ready to make pro-quality recordings.
Hands-on mixing for studio and stage
Quickly balance the levels of mics, guitars, a keyboard, or other inputs right from the front panel. Each input has its own volume control. Route inputs directly to any output pair, each with its own unique mix: main outs, line outs, S/PDIF out, and phones.
Your mix will be ready for prime time
The 4pre has been engineered with MOTU’s renowned, award-winning audio interface technology, which delivers the pristine audio quality and rock-solid performance that MOTU interfaces are known for worldwide. You can always record and mix with confidence, knowing that decades of engineering experience are behind you, every step of the way.
On-screen mixing and control
The included CueMix software for Mac OS X and Windows gives you graphic, on-screen control of the 4pre's on-board audio mixer, with up to four separate stereo mixes (a separate mix for each output pair). For example, you can mix all the inputs to the main outs, but also mix them to the line outs with completely different levels than the main outs. Advanced features include a tuner, oscilloscope, FFT/spectrogram, and phase analysis tools.
