Description

CX302 100W Stereo Power Amp

Features

Eight two-channel models to meet your exact power requirements

Three 70-volt direct models
Five low-impedance models; the CX902 and CX1102 also directly drive 70 volt loads

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 and QSControl computer 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 withminimal effect on program material (33 Hz or 75 Hz on non-V models, 50 Hz or 75 Hz on V models)
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
Class H complementary bipolar output circuitry for high efficiency (CX702, CX902, CX1102, and CX1202V)
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 - all models are only 2 rack units high and 14" deep for reduced rack cost and floor space
Light weight - all models weigh only 21 pounds (9.5 kg) for easier racking and shipping
3-year warranty plus optional 3-year extended service contract
