The SPA2-60 SPA Series 2 Channel Audio Amplifier delivers 60 watts RMS per channel into 4 or 8 ohms; the two channels can also be bridged providing up to 200 watts rms into 4 or 8 ohms. When the channels are bridged they can be switched into 70V or 100V direct drive mode providing up to 250 watts rms into a mono 70V or 100V output. There is also an 80Hz highpass filter for bridged operation ensuring that 70V or 100V loudspeakers transformers are not overdriven and saturated by too much low frequency content. The SPA2-60 is ideal for stereo or mono applications of voice or music audio content.
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.
