Product Overview

The QSC ISA800Ti amplifier is equipped with an internal 70V transformer and designed specifically for sound contractors. It can be used as a low-impedance solution rated for 2-Ohm operation at 1200W per side, or 8 Ohms at 450W per side. The versatile loading options, feature set, and protection circuitry, in addition to the built-in HD-15 DataPort V2 DSP interface capability, ensures a high-value, cost-effective solution for budget-minded installations.

The ISA800Ti is housed in a rugged all-metal chassis and features rear-panel gain controls for tamper-resistant operation with 2 dB 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.

Features:

Low-impedance outputs plus isolated 25, 70, and 100 volt outputs for distributed audio systems
Rear panel gain controls for tamper resistance; 2-dB detents allow for quick and repeatable settings
XLR and detachable Euro-style input connectors
DataPort V2 for use with DPV2-compatible signal processing accessories (XC-3, SF-3, LF-3) and DSP-3/DSP-4 (with external power supply)
Independent defeatable clip limiters for reduced distortion
Selectable high-pass filters (50 Hz or 75 Hz) protect speakers and prevent speaker transformer saturation, with minimal effect on program material
Two-tier Class H complementary bipolar output circuitry reduces AC power draw and waste heat by 40%
Front panel indicators include power, signal, and clip
Covered barrier strip output connectors for safety agency compliance
Automatic on-demand variable-speed fan: quiet normal operation, with maximum cooling when needed
Rear-to-front air flow helps keep equipment racks cool
Stereo, bridge, or parallel operating modes
Comprehensive protection circuitry including DC, infrasonic, thermal overload, and short circuit protection
3-year warranty plus optional 3-year extended service contract
