The QSC ISA750 is a rugged two-channel installation power amplifier from the ISA Series, engineered for demanding fixed-install and contractor applications. It drives conventional low-impedance loudspeaker loads with generous headroom, making it a strong choice for houses of worship, auditoriums, stadiums, and other high-output installed systems. Rated at 450 watts per channel into 8 ohms and 650 watts into 4 ohms, it can be bridged to mono for even greater output. The ISA750 features detented level controls, balanced inputs, and comprehensive protection in a durable three-rack-space chassis designed for continuous duty.
