ISA1350

Commercial Power Amplifier

Features

Drives 70V lines directly with 1500 watts per channel
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 (30 Hz or 70 Hz) protect speakers and prevent speaker transformer saturation, with minimal effect on program material
Three-tier Class H complementary bipolar output circuitry reduces AC power draw and waste heat by 50%
Front panel indicators include power, signal, clip and protect
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
