Active USB Desktop Studio Monitors, Alesis M1 Active 520USB

M1Active 520 USB is a studio monitoring system designed for professional studio use, that also feature an integrated USB audio interface with 16-bit, 44.1/48 kHz recording and playback. It consists of a pair of active, bi-amplified, two-way reference monitors that play from 20,000 Hz all the way down to 56 kHz to cover nearly all frequencies audible to human ears. A switchable power supply ensures worldwide operation, and M1Active 520 USB are class compliant, no drivers required.

The I/O include two balanced-1/4" inputs for connecting a stereo source or two mono sources. For convenient recordings, simply connect the stereo output of a mixer. You can create complete recordings with no additional audio interface! There is also a stereo, 1/4" headphone output that mutes the loudspeakers when connected. When you connect headphones, the main volume control automatically switches to controlling the headphone output.

The M1Active 520 USB feature five-inch polypropylene low-frequency drivers for full, smooth response in the low end and one-inch silk dome high-frequency drivers for absolute clarity in the highs. The custom crossover avoids the crucial vocal midrange, ensuring that your mixes sound the way you recorded them. A bass boost switch offers low-frequency enhancement to further accommodate for room conditions requiring a little more output in the low end. The low-resonance cabinet has a tuned bass port.

Overall the M1Active 520 USB is a 60W system, 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 work with iPad via Apple USB Adaptor (sold separately). A bi-colour signal/clip indicator indicates presence of signal in blue and clipping in red for instant feedback on system status.
