QSC CX302 2-Channel Low-Z Power Amplifier
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)
- Comprehensive front panel indicators including signal, clip, protect and QSC's exclusive bridge mono and parallel input LEDs
- Barrier strip output connector
- Comprehensive protection circuitry including DC, infrasonic, thermal overload and short circuit protection
- Optional external transformer accessory pack for isolated 25-, 70-, and 100-volt outputs (converts CX302 to 400 watts per channel, or 300 watts into 25 V)
- 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.
