QSC ISA750 Installed System Power Amplifier

The ISA750 is a THX-approved member of QSC's ISA Series, built for low-impedance install systems that need real headroom rather than a 70V line. Class H 2-tier output circuitry cuts AC draw and heat, and the amp is rated down to 2 ohms per channel for driving multiple parallel loudspeakers off one channel.

Rear-panel gain controls with 2 dB detents keep levels tamper resistant, and a DataPort V2 connector accepts QSC's DPV2 signal-processing accessories. Defeatable clip limiters, a selectable 30/70 Hz high-pass filter, and full short circuit, thermal, and RF protection round out a rack amp meant to run unattended.
