Description

QSC CX404 4 channels, 250 watts/ch at 8Ω, 400 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 CX404 4 channels, 250 watts/ch at 8Ω, 400 watts/ch at 4Ω.

Features

Compact size — only 2 RU and 14" deep for reduced rack cost and floor space
Bridgeable channels 1 + 2 and 3 + 4, for maximum flexibility
Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
HD15 DataPort connector for Q-SYS networked control and monitoring
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
Detachable Euro style input connectors
DIP switch control for clip limiters, high pass filters, bridge mono and parallel operation
Exclusive PowerLight switch-mode power supply technology for high performance and compact size
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
High-performance Class AB+B complementary bipolar output circuitry
