QSC ISA1350 Installed System Power Amplifier

The ISA1350 is the top of QSC's ISA Series install amplifiers, built to drive a 70V distributed line directly at 1,500 watts with less than 0.5% THD, no output transformer required. Class H, 3-tier output circuitry cuts AC draw and waste heat versus a conventional design, and rear-panel gain controls with 2 dB detents keep levels tamper resistant and repeatable once a system is commissioned.

A DataPort V2 connector accepts QSC's DPV2 signal-processing accessories, and defeatable clip limiters, selectable 30/70 Hz high-pass filters, and full short circuit, thermal, and RF protection keep the amp and the line it feeds safe. Stereo, bridge, or parallel operation and covered barrier-strip outputs make it a straightforward retrofit into an existing rack.
