Energy Star qualified QSC SPA2-60 amplifier effeciently conserves energy, which helps reduce operational costs.

The QSCSPA2-60 amplifiers are two half rack 1U, convection cooled power amplifiers delivering two or four channels of 60 watts per channel into 4-ohms and 8-ohms. These amps can also be bridged to supply 200 watts into 4-ohms and 8-ohms, and up to 250 watts into 70V or 100V loads making them extremely flexible for Low-Z or High-Z applications. Utilizing an advanced Class-D amplifier design and Universal Power Supply the SPA Series are amazingly efficient allowing them to be convection cooled and are ENERGY STAR® qualified with quiet auto-ramp standby functionality. The SPA2-60 and SPA4-60 are housed in an unobtrusive black painted 1/2 RU chassis with unique mounting hardware enabling rack, table and wall mounting capabilities.

• 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 STAR® qualified amplifier - The SPA2-60 and SPA4-60 are EnergyStar qualified amplifiers; efficient class-D amplifiers that conserve energy and require no active cooling, so they reduce operational costs.
• Bridgeable outputs for higher power - Bridging the outputs of the SPA2-60 and SPA4-60 provide up to 200 watts into low impedance, and up to 250 watts into 70V or 100V providing outstanding flexibility.
• Auto-Ramp provides quiet startup and power-down - The EnergyStar Auto-Ramp circuitry ensures quiet and fast power up from Standby and seamless power-down following 28 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.
