Alesis RA150 Stereo Power Amplifier, 45W Per Channel into 8 Ohms

The RA150 is designed to provide more power and better performance. As a result, it can more closely match the power needs of virtually any passive speaker or studio monitor and provides a crisp, clean signal for outstanding performance and extended speaker life.

Designed for studio use, the RA150 amp incorporates advanced convection cooling for heat dissipation. The result is long, stable operation unaffected by heat-related complications and without the added distraction and annoyance of fan cooling. This eliminates the frustration of trying to hear quieter details due to noisy amp performance.
