The SPA4-60 from QSC is a 4-channel, 60W power amplifier that delivers up to 200 watts per channel into Low-Z loads. When two channels are bridged, providing up to 200 watts into 4Ω and 8Ω, and up to 250 watts into 70V or 100V.
More about QSC’s SPA Series
Power up your audio with confidence with the SPA Series from QSC. These efficient power amplifiers deliver two or four channels of up to 200 watts per channel into 4Ω and 8Ω. Their outputs can be bridged for an extremely flexible solution for Low-Z or High-Z applications.
SPA power amps sport an advanced Class-D amplifier design and Universal Power Supply, allowing them to be convection-cooled, conserve energy, and reduce operational costs. All amplifiers in the SPA Series feature rms and thermal limiting, as well as protection against over current, short circuit, and under/over voltage.
They are also ENERGY STAR qualified, allowing for fast and quiet powering up from Standby, while the cutting-edge auto-ramp circuitry that transitions with no audible pops. SPA series amps automatically power down after 25 minutes of inactivity, which dramatically reduces power consumption.
The SPA Series are housed in an unobtrusive black painted 1/2 RU chassis. They can be mounted in 1RU, ½ wide rackspace, and include all the hardware you need to mount it in a rack, under the table, or on the wall. The included connecting brackets provide additional sturdiness when mounting two amps together. The SPA Series is also compatible with mounting in plenum spaces when using the Plenum Kit accessory (sold separately).
