SPA Series

EnergyStar Amplifiers

The SPA Series amplifiers from QSC are four half rack 1U, convection cooled power amplifiers delivering two or four channels of up to 200 watts per channel into 4Ω and 8Ω. These amplifiers can also be bridged to supply up to 400 watts into 4Ω and 8Ω, and up to 350 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 SPA Series amplifiers are housed in an unobtrusive black painted 1/2 RU chassis with unique mounting hardware enabling rack, table and wall mounting capabilities.

Efficient class-D amplifiers that conserve energy and require no active cooling, so they reduce operational costs.

Bridging the outputs of the SPA2-60 and SPA4-60 amplifiers provide up to 250 watts, while the SPA2-200 and the SPA4-100 will deliver up to 350 watts into 70V or 100V when bridged.

The ENERGY STAR® Auto-Ramp circuitry ensures quiet and fast power up from Standby when signal is present, and seamless power-down following 25 minutes of inactivity, dramatically reducing power consumption.
