The QSC SPA4-60 four channel amplifier delivers 60 watts rms per channel into 4 or 8 ohms; the four channels can also be bridged in pairs, each pair providing up to 200 watts rms into 4 or 8 ohms. Like the SPA2-60, the bridged channels of the SPA4-60 can be switched into 70V or 100V direct drive mode providing up to 250 watts rms into a 70V or 100V output; each bridged output also features an 80Hz highpass filter. The SPA4-60 is perfect for applications with mixed outputs such as four low-Z outputs for a mix-minus system, a stereo TV reinforcement system with a 70V or 100V output for ceiling conferencing speakers, a stereo with mono Subwoofer system, or even two sets of 70V or 100V outputs for a zoned system.
The SPA Series amplifiers from QSC are two 1 RU, 1/2 rack space, convection cooled power amplifiers delivering two or four channels of 60 watts per channel into 4Ω and 8Ω. These amps can also be bridged to supply 200 watts into 4Ω and 8Ω, 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. Both amplifiers in the series are ENERGY STAR qualified with quiet auto-ramp standby functionality. The SPA2-60 and SPA4-60 are housed in an unobtrusive black chassis with unique mounting hardware enabling rack, table and wall mounting.- Features
