QSC CX902
Features
Exclusive PowerLight switch-mode power supply technology for high performance and compact size
Custom integrated security cover for tamper proof installations
Variable speed fan for low noise
1-dB detented gain controls for fast and accurate gain settings
Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
XLR and detachable Euro style input connectors
HD15 DataPort connector for Q-SYS networked control and monitoring
Dip switch control for clip limiters, high pass filters, bridge mono and parallel operation
Selectable high pass filters protect speakers and prevent speaker transformer saturation with minimal effect on program material (33 Hz or 75 Hz)

Barrier strip output connector
Comprehensive protection circuitry including DC, infrasonic, thermal overload and short circuit protection
Class H complementary bipolar output circuitry for high efficiency
Optional external transformer accessory pack for isolated 25-, 70-, and 100-volt outputs
Compact size - only 2 rack units high and 14" deep for reduced rack cost and floor space
Lightweight - weighs only 21 pounds (9.5 kg) for easier racking and shipping
3-year warranty plus optional 3-year extended service contract
All CX Series amplifiers meet the European Union's 2006 RoHS directive to restrict the use of hazardous materials used in electronic devices.
