QSC ISA 800Ti 70V Dual Channel Amplifier

In Stock 1
Designed as a cost-effective solution specifically for sound contractors, the versatile loading options and a comprehensive feature set make the ISA Series a rugged, cost-effective power solution for any permanently installed sound system. Unique among distributed sound power amplifiers, the "Ti" series will drive 8 or 4 ohm 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 that is powering the main sound system. The ISA 800Ti is rated at 450 watts RMS per channel into 8 ohms, 650 into 4 ohms (20 Hz-20 kHz, 0.1% THD). 2 ohm load rating is 1,200 watts RMS per channel (1 kHz, 1% THD). Bridged mono output produces 1,500 watts RMS into 8 ohms, 2,400 into 4 ohms (1 kHz, 1% THD). 70V rated output is 800 watts RMS per channel (50 Hz-16 kHz, 0.5% THD).

  • 25-, 70-, 100 volt, and low impedance outputs available simultaneously
  • Simple barrier strip connection determines output mode
  • Rear panel gain controls for tamper resistance
  • XLR and detachable Euro style input connectors
  • DataPort V2 for use with DPV2-compatible signal processing accessories
  • Independent defeatable clip limiters for reduced distortion
  • Selectable 30 Hz or 70 Hz high-pass filters protect
  • Class H output circuitry reduces heat and AC power draw by 40% on ISA 800Ti
  • Front panel indicators include power, signal, and clip
  • Covered barrier strip output connectors for safety agency compliance
  • Automatic variable-speed fan
  • Rear-to-front air flow keeps equipment racks cool
  • Stereo, Bridge, or Parallel operating modes
  • DC, infrasonic, thermal overload, and short circuit protection
Housed in a rugged three rack space chassis, all models feature rear panel gain controls for tamper resistant operation with 2 dB detents 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 like the DSP-3.

Selectable high-pass filters are included to protect speakers and prevent speaker transformer saturation with minimal effect on program material. The ISA Series amps provide additional protection circuitry including DC, infrasonic, thermal overload, RF and short circuit protection. On the ISA 800Ti, Class H complementary bipolar output circuitry increases system efficiency by reducing AC power draw and waste heat by 40%. Cooling is accomplished via an automatic variable speed fan, which pulls air from back to front.
