QSC CX108V
Features
100 watts per channel at 70 volts
Compact size—only two rack spaces and 14" deep for reduced rack space
Channel pairs bridgeable for maximum flexibility
Exclusive PowerLight switch-mode power supply technology for high performance and compact size
Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
Four HD15 DataPort connectors (one per channel pair) for Q-SYS networked control and monitoring
Custom integrated gain control security cover for tamper-proof installations
1-dB recessed detented gain controls for fast and accurate settings
Detachable Euro-style input and output connectors
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 (50 Hz or 75 Hz)
Comprehensive front panel indicators including signal, clip, bridge mono and parallel input LEDs
Fully protected—including DC, infrasonic and ultrasonic, thermal overload and short circuit protection
High-performance Class AB+B complementary bipolar output circuitry
Lightweight—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.
