The QSC ISA 1350 Amplifier includes a selectable high-pass filter to protect speakers and prevent speaker transformer saturation with minimal effect on program material. The ISA Series provides additional protection circuitry.

Description

The ISA1350 Amplifier includes a selectable high-pass filter to protect speakers and prevent speaker transformer saturation with minimal effect on program material. The ISA Series provides additional protection circuitry including DC, infrasonic, thermal overload, RF and short circuit protection. Versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system.

Features

ISA 1350 drives 70V lines directly with 1500 watts / channel
Rear panel gain controls for tamper resistant operation with 2 dB detents 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
Front panel indicators include power, signal, and clip
Covered barrier strip output connectors for safety agency compliance
Automatic variable-speed fan for quiet normal operation with maximum cooling on demand
Rear-to-front air flow keeps equipment racks cool
Stereo, Bridge, or Parallel operating modes
Comprehensive protection circuitry including DC, infrasonic, thermal overload and short circuit protection
25, 70, 100 volt, and low-impedance outputs available simultaneously
