Alesis has introduced the Sumo 15 amplifier. A compact, versatile keyboard / PA amplifier with built-in effects, two channels (one for a microphone, one for a stereo keyboard), Stereo Link, and a headphone output, the new Sumo 15 is the ideal complement for keyboard players in search of a practice or monitor solution as well as for small PA applications.

The Sumo 15 offers a compact form factor housing an 8-inch full range driver powered by a 15-watt, 2-channel amplifier. The Sumo 15 offers a dedicated microphone channel with an XLR input and a second channel providing right and left quarter-inch inputs for accommodating keyboard instruments. Both channels provide post fader effects sends for use with the amp’s internal signal processing. With 2-band EQ in the Sumo 15’s Master section, this arrangement makes this amplifier a great choice not only as a practice solution, but also for the solo keyboard/vocal performer working an intimate room. And to further enhance its capabilities for small PA or monitor usage, the Sumo 15 incorporates a pole cup on the underside of the enclosure for use as a “speaker on a stick”—enabling the cabinet to be elevated for greater sound coverage.

With integrated digital signal processing (DSP), the Sumo 15 provides fifteen advanced, stereo effects. These include rotary speaker emulation for use with organ sounds, hall, room and plate reverbs, chorus, delay, flange, and two combination chorus/reverb settings. With all these great stereo effects, musicians will certainly appreciate the Sumo 15’s Stereo Link feature. Utilizing quarter-inch input and output connectors, this feature enables users to connect the Stereo Link output of one Sumo 15 to the Stereo Link input of a second unit and achieve true stereo via dual cabinets for a great, low cost stereo PA system. For enjoying true stereo effects with a single Sumo 15, there is a quarter-inch stereo headphone output incorporated into the Sumo 15’s rear panel.

Commenting on the capabilities of the Sumo 15, Alesis CEO Jack O’Donnell noted, “The Sumo 15 is a versatile performer and a noteworthy addition to Alesis’ Sumo line of keyboard/PA amplifier products. Its compact size and rich feature set make this amp a terrific choice for a wide range of keyboard performers.”

The Sumo 15 has a suggested retail price of $229 and will be available Q3 of 2005.
