The highly flexible QSC SPA4-60 4-Channel Power Amplifier is an advanced Class-D amplifier with Energy Star rated efficiency well suited for smaller installations including meeting rooms or BGM zones. The convection cooled amplifier is designed to conserve energy. An auto-ramp circuit ensures quiet and fast power up from standby when a signal is present and seamless power-down following 25 minutes of inactivity, dramatically reducing power consumption.
