The QSC ISA-750 is a 3RU rackmount power amplifier designed specifically for sound contractors as a low impedance solution rated for 2-ohm operation at 1200 watts per side, or 450 watts at 8 ohms. The versatile loading options, feature set and protection circuitry, in addition to the built-in HD-15 DataPortV2 DSP interface capability, ensures a high-value, cost-effective solution for budget-minded installations.
The ISA-750 is housed in a rugged all-metal chassis, and features rear panel gain controls for tamper resistant operation with 2dB detents for quick and repeatable settings. The inputs include both XLR and detachable Euro-style connectors and the outputs feature covered barrier strip connectors for full safety agency compliance.
