The Alesis M1Active 520 USB is a professional studio monitoring system boasting an internal digital-audio interface and featuring a pair of active, bi-amplified, two-way reference monitors (50W LF, 25W HF) that play from 20 kHz all the way down to 56 Hz to cover nearly all frequencies audible to human ears. Its digital input allows you to take a digital signal out of your computer via USB and input it to M1Active 520 USB thanks to their digital input. The Alesis M1Active 520 USB performs with the linearity, clarity and neutrality usually found in monitors that cost much more.

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

Professional quality analog input jacks are located on the rear. Two balanced-1/4" inputs let you connect 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. The speakers are interconnected using a standard XLR cable for secure, professional connection. For worldwide operation, the M1Active 520 USB features a voltage-switchable power supply.

The Alesis M1Active 520 USB features a large, front-panel, bi-color indicator that indicates presence of signal in blue and clipping in red for instant feedback on system status. A front-panel stereo 1/4" headphone output mutes the loudspeakers when connected. When you connect headphones, the main volume control automatically switches to controlling the headphone output.

In addition to their capabilities as traditional monitor loudspeakers, Alesis 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 USB.
