RA150 REFERENCE AMPLIFIER |
ALESIS SOUND TOOLS Play it loud, keep it clean, thump the room, make it scream. Hear your music in a transparent oasis of supersonic detail. Left brain/right brain gives way to the peripheral vision of colour. Are you not a human being? No... You're a lean mean mixing machine. INSPIRE. PLAY. CREATE.  |

A better way to amp up your studio The last thing you need to worry about in the control room is monitoring. When the sound counts - and it always does - you need stable, generous power for your reference monitors.That's why Alesis designed the RA series of reference amplifiers. Attractive, yet built like tanks. Powerful, yet priced lower per watt than the competition. The RA150, RA300, and RA500 were also designed with advanced convection cooling to run for long periods while staying cool without the use of a fan. This eliminates extra noise that can complicate mixing and recording in a studio. Each amp has 1/4” TRS and RCA input connectors, and the RA300 and RA500 add XLR inputs. Get your monitors the clean, steady power they need. Listen to the music - and nothing else. |
