Focusrite Sound Inside

This isn't just a USB hub; it's a powerful audio interface too. Novation partnered with Focusrite, who make the best sounding audio interfaces in the world, to make sure Audiohub 2x4 gives you extraordinary quality 96 kHz, 24-bit audio performance. This allows you to sample and capture pristine quality audio and listen back with zero latency at the click of a button.

Perfect for Live Performance

Connect your main speakers and cue sub to high quality balanced and unbalanced outputs, with totally independent level control. The headphone output is also ludicrously loud, which is essential.

Beat Making and Sampling with NI Maschine

Sample pristine audio through matched stereo inputs and Focusrite audio conversion, then play it back with the same exceptional quality audio, ultra-low latency and super-loud outputs. Do it all while bus-powering all read more your USB gear, so you don't have the usual cable and power supply clutter.

You can even connect it all to your iPad, if you have a camera connection kit.
