USB Digital Audio Interface

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.

Designed for professional studio use combined with a stereo USB audio interface, the M1Active 520 USB studio monitor covers nearly

all frequencies audible to human ears--from 20,000 Hz all the way down to 56 Hz. And with its USB capabilities, you can take USB

digital signal out of your computer and input it to M1Active 520 USB for low-noise, low-distortion performance.

This package includes a pair of M1Active 520 USB monitors.

The M1Active 520USB around a 5-inch polypropylene low-frequency driver for full, smooth response in the low end and a 1-inch silk dome high-frequency

driver for absolute clarity in the highs. Alesis' custom crossover avoids the crucial vocal midrange, ensuring that your mixes sound the way you recorded them.

The low-resonance bass reflex cabinet features radiussed 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.

The 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. The front-panel stereo 1/4-inch headphone output mutes the loudspeakers when connected.
