QSC CX168 8 channels, 90 watts/ch at 8Ω, 130 watts/ch at 4Ω

Description QSC CX168 8 channels, 90 watts/ch at 8Ω, 130 watts/ch at 4Ω With this 4-channel CX amplifiers it can give you four channels, without compromising the power, in only two rack spaces. You can choose from three models, two low-impedance versions and a one direct 70 volt model. Each of this model is crafted with exclusive QSC Powerlight™ switching power supply technology to eliminate the hum and noise virtually. The CX Series is the perfect solution because it is designed with high-thermal capacity, high-output power, versatile loading options and unmatched reliability, to any permanently installed sound system. One of this amplifier is QSC CX168 8 channels, 90 watts/ch at 8Ω, 130 watts/ch at 4Ω. Features 90 watts per channel at 8 ohms and 130 watts per channel at 4 ohms 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 DataPorts (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 (33 Hz or 70 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.
