2-Channel Compact Power Amplifier, 60W at 4 Ohm, 70V


The SPA Series amplifiers from QSC are two half rack 1U, convection cooled power amplifiers delivering two or four channels of 60 watts per channel into 4Ohm and 8Ohm. The two channels can be bridged to supply 200 watts into 4Ohm and 8Ohm - and up to 250 watts into direct drive 70V or 100V mode - making them flexible for Low-Z or High-Z applications. There is also a selectable 80Hz highpass filter for bridged operation, ensuring that 70V or 100V loudspeakers 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 EnergyStar qualified with quiet auto-ramp standby functionality.

The SPA2-60 and SPA4-60 are housed in an unobtrusive black painted 1/2 RU chassis with clever joining brackets that enable easy under-table and wall-mounting. This unit is 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. The SPA2-60 and SPA4-60 can be mounted in ½ RU to reduce rack space requirements.

QSC SPA2-60 Features:

  • ENERGY STAR® qualified amplifier:
    • The SPA2-60 and SPA4-60 are EnergyStar qualified amplifiers; efficient class-D amplifiers that conserve energy and require no active cooling, so they reduce operational costs
  • Bridgeable outputs for higher power:
    • Bridging the outputs of the SPA2-60 and SPA4-60 provide up to 200 watts into low impedance, and up to 250 watts into 70V or 100V providing outstanding flexibility
  • Auto-Ramp provides quiet startup and power-down:
    • The EnergyStar Auto-Ramp circuitry ensures quiet and fast power up from Standby and seamless power-down following 28 minutes of inactivity,dramatically reducing power consumption
