ISA500Ti

Commercial Power Amplifier

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
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
