- Description
Details
This QSC ISA750 Power Amplifier includes a selectable high-pass filters to protect speakers and prevent speaker transformer saturation with minimal effect on program material. The ISA Series provide additional protection circuitry including DC, infrasonic, thermal overload, RF and short circuit protection. Selectable high-pass filters are included to protect speakers and prevent speaker transformer saturation with minimal effect on program material. Versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.
