The Alesis M1Active 520 USB is a professional studio monitoring system designed for studio use with an internal digital-audio interface. M1Active 520 USB consists of a pair of active, bi-amplified, two-way reference monitors that play from 20,000 Hz all the way down to 56 Hz to cover nearly all frequencies audible to human ears. You can take USB digital signal out of your computer via USB and input it to M1Active 520 USB for low-noise, low-distortion performance. Priced attractively for any studio's budget, M1Active 520 USB perform with linearity, clarity, and neutrality typically reserved for monitors that cost much more.
When you reach for the convenient front panel volume control, you can be confident that the power you need will be there with M1Active 520 USB's bi-amplified design delivering 30W per speaker. Like the rest of the M1Active series, M1Active 520 USB are magnetically shielded, so there's never an issue of placement near computer screen, LCDs, or hard drives.

M1Active 520 USB feature a large, front-panel, bi-color indicator that indicates presence of signal in blue and clipping in red for instant feedback on system status.
In addition to their capabilities as traditional monitor loudspeakers, M1Active 520 USB monitors contain a USB audio interface. Connected audio sources such as mic preamps and instruments can be recorded directly into your computer at 16-bit, 44.1 or 48 kHz. Simply plug the USB cable into your computer. No special drivers required. And when it's time to listen back to your mixes, that same USB cable sends 16-bit, 44.1 or 48 kHz, stereo audio from computer to your M1Active 520 USBs. No more complicated interfaces and messy cable tangles.
