Description
The SPA Series amplifiers from QSC are two half rack 1U, convection cooled power amplifiers delivering two or four channels of 60W per channel into 4 Ω and 8 Ω. The two channels can be bridged to supply 200W into 4 Ω and 8 Ω - and up to 250W into direct drive 70 V or 100 V mode - making them flexible for Low-Z or High-Z applications. There is also a selectable 80 Hz highpass filter for bridged operation, ensuring that 70 V or 100 V loudspeaker transformers are not overdriven and saturated by too much low frequency content. Utilizing an advanced Class-D amplifier design and Universal Power Supply, the SPA Series are remarkably efficient and are ENERGY STAR® qualified with quiet auto-ramp standby functionality.
The SPA4-60 is housed in an unobtrusive black painted 1/2 U chassis with clever joining brackets that enable easy under-table and wall-mounting. It's ideal for stereo or mono applications of voice or music audio content, and offers a powerful yet affordable amplifier that meets the needs of boardrooms, conference rooms and other corporate spaces where multiple speakers are in use.
