SPA4-60
Power Amplifier
Features & Benefits
Up to 60 watts per channel into 4 and 8 ohms — The outputs of the SPA2-60 and SPA4-60 are designed to provide 60 watts per channel into Low-Z loads
Energy efficient — The SPA4-60 power amplifier employs an efficient class-D design to conserve energy and requires no active cooling, reducing operational costs.
Bridgeable outputs for higher power — Bridging the outputs of the SPA4-60 provides up to 100 watts per bridged pair into low impedance, and up to 125 watts per bridged pair into 70V or 100V providing outstanding flexibility.
Auto-Ramp provides quiet startup and power-down — The Auto-Ramp circuitry ensures quiet and fast power up from Standby and seamless power-down following 25 minutes of inactivity, dramatically reducing power consumption.
Rack-mountable 1U, half rack width enclosure — The SPA2-60 and SPA4-60 can be mounted in 1/2 RU reducing rack space requirements. In addition their clever joining brackets enable easy under-table and wall-mounting.
