QSC CX302 เพาเวอร์แอมป์ เครื่องขยายเสียง
Features
o Eight two-channel models to meet your exact power requirements
o Three 70-volt direct models
o Five low-impedance models; the CX902 and CX1102 also directly drive 70 volt loads
o Exclusive PowerLight switch-mode power supply technology for high performance and compact size
o Custom integrated security cover for tamper proof installations
o Variable speed fan for low noise
o 1-dB detented gain controls for fast and accurate gain settings
o Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
o XLR and detachable Euro style input connectors
o HD15 DataPort connector for Q-Sys and QSControl computer control and monitoring
o Dip switch control for clip limiters, high pass filters, bridge mono and parallel operation
o Selectable high pass filters protect speakers and prevent speaker transformer saturation withminimal effect on program material (33 Hz or 75 Hz on non-V models, 50 Hz or 75 Hz on V models)
o Comprehensive front panel indicators including signal, clip, protect and QSC's exclusive bridge mono and parallel input LEDs
o Barrier strip output connector
o Comprehensive protection circuitry including DC, infrasonic, thermal overload and short circuit protection
o Class H complementary bipolar output circuitry for high efficiency (CX702, CX902, CX1102, and CX1202V)
o 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)
o Compact size - all models are only 2 rack units high and 14" deep for reduced rack cost and floor space
o Light weight - all models weigh only 21 pounds (9.5 kg) for easier racking and shipping
o 3-year warranty plus optional 3-year extended service contract
o All CX Series amplifiers meet the European Union's 2006 RoHS directive to restrict the use of hazardous materials used in electronic devices.
