Product Overview

Designed as a cost-effective solution specifically for sound contractors, QSC's ISA800TI has isolated 25, 70 and 100 Volt outputs for distributed audio systems, and a comprehensive feature set to make this unit a rugged, cost-effective power solution for any permanently-installed sound system. Unique among distributed sound power amplifiers, it'll drive 8 Ω or 4 Ω 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 a rugged 3-U chassis, all seven models feature rear panel gain controls for tamper resistant operation with 2 dB detentes 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, LF-3 Low Frequency Filter and the DSP-3 with external power supply. Selectable high-pass filters are included to protect speakers and prevent speaker transformer saturation with minimal effect on program material. The ISA800TI provides additional protection circuitry including DC, infrasonic, thermal overload, RF and short circuit protection.
