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.
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.
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.
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.
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.
The 4pre aluminium alloy chassis is lightweight, yet incredibly sturdy and durable, and designed to withstand the rigors of the studio, stage, and tour bus. In a world awash with cheap plastic, the cool touch of the 4pre’s metal exterior in your hands is a reassuring reminder that you are holding quality engineering and construction built to last.
