good looks - among the first examples of Alesis' groundbreaking new approach to industrial design - and a long list of features, the new RA500 amps will quickly find a home in project and commercial recording studios, broadcast an post-production control rooms around the world.Even with the increasing use of powered speakers, many popular speakers and headphones still require external amplification. These new amps are designed to provide more power and better performance at a lower overall cost per watt than even RA100 - as well as any other competing models. As a result, they can more closely match the power needs of virtually any passive speaker or studio monitor, offering a significantly better fit for an ex...  (less)

that's within reach of today's home studio owner. One recording gig could easily pay for the investment! With a new, custom 6.5' woofer, a redesigned 1' pure silk tweeter dome, two audiophile-quality amplifiers (independently 75W and 25W) these monitors offer improved response and clear imaging. Even the cabinet design and crossover were tweaked to allow for the most accurate reproduction possible. Add the Alesis Monitor 1 MKII monitors to your studio and experience the benefits of biamp reference monitors. Professional Accuracy, Clarity and Performance in an Affordable Powered Monitor By combining their expertise in reference monitor design with our proven track record in studio amplification, Alesis' new M1 Activeâ„¢ Biamplified Reference Monitor offers the incredibly accurate response that perfectly translates to every playback system. Its internal active crossover and custom-designed dual amplifiers ensure an extremely consistent performance under a variety of different studio conditions and program material. The result is a broad, extremely flat frequency response, clear imaging with a wide sweet spot, high power handling and detailed high- and mid-frequency response that only a professional powered monitor can deliver. Custom Drivers Designed For Active Monitoring The M1 Active's woofer and tweeter were specifically designed for the most linear, low distortion response in powered monitoring applications. Its 6.5' woofer cone is formulated from non-woven carbon fiber. It's a material that has been used for the skins of combat aircraft wings, since it offers high tensile strength and low weight. In fact, carbon fiber is 25% lighter than polypropylene (the most common driver material) and hence provides quicker transient response in the low frequency range for superb bass response as well as a vast improvement in the detail of critical upper-mid frequencies. The M1 Active's 1' tweeter dome is made of pure silk, which offers a natural response that aids in preventing ear fatigue during long mix sessions. It also features an internal pole piece mounted phasing plug and is ferrofluid cooled to maintain the best balance of transient response to power handling. Active Bi-Amplifiers and Electronic Crossovers Two audiophile-quality amplifiers-a 75 watt woofer amp and a 25 watt tweeter amp-were developed for the M1 Active, along with 8th order high- and low-pass electronic crossover filters. The crossover point was carefully chosen at a low 1500Hz, and produces an extremely wide dispersion zone as well as low midrange coloration. Also, the special time alignment circuitry that's been added to the tweeter section of t  (less)

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 digital signal out of your computer via USB and input it to M1Active 520 USB thanks to their digital input. Priced attractively for any studio's budget, M1Active 520 USB perform with linearity, clarity, and neutrality typically reserved for monitors that cost much more. REFERENCE MONITORING We built M1Active 520USB around our popular five-inch polypropylene low-frequency driver for full, smooth response in the low end and our one-inch silk dome high-frequency driver for absolute clarity in the highs. Our 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. PROFESSIONAL MONITORING OPTIONS 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 25W to the tweeter and 50W to the woofer. 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. The 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. 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. EXTENSIVE I/O Professional quality analog input jacks are located on the rear. Two balanced-1/4"" inputs enable engineers to 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, M1Active 520 USB features a voltage-switchable power supply. 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.
