QSC Launches ISA Series

Designed as a cost-effective solution specifically for sound contractors, the new ISA Series from QSC Audio features six models, including three low impedance models (ISA 280, ISA 450, ISA 750) rated for 2-ohm operation, and three ‘T’ versions with 25, 70 and 100 volt outputs for distributed audio systems (ISA 300T, ISA 500T, ISA 800T). Versatile loading options and a comprehensive feature set make the ISA Series a suitable power solution for a wide range of permanently installed sound systems. The ‘T’ versions will drive 8- or 4-ohm loads and a distributed system on the same channel simultaneously. This enables a contractor to reduce the number of required amplifier channels by allowing a limited number of distributed speakers to be attached to the same amp as is powering the main sound system.

Housed in rugged 3U chassis, all six models feature rear panel gain controls for tamper resistant operation with 2dB detents for quick and repeatable settings. Inputs include both XLR and detachable Euro-style connectors. Outputs feature covered barrier strip connectors for safety agency compliance, and for added versatility, a DataPort V2 (Version 2) terminated with an HD-15 connector is provided for use with DPV2-compatible signal processing accessories such as the XC-3 Crossover, SF-3 Subwoofer Filter, and the LF-3 Low Frequency Filter. Selectable high-pass filters are included 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.
