2-Channel Power Amplifier, 425 Watts @ 8 ohms


The QSC CX Series of amplifiers are designed to meet the specialized needs of sound contractors. Five low impedance models and three 70-volt direct models have been designed from the ground up, combining QSC's exclusive PowerWave technology with specific features to meet the requirements of fixed installations. With high output power, versatile loading options, high thermal capacity and reliability, the CX Series is the ideal solution ot any permanently installed sound system.

The CX amplifiers are equipped with many contractor-specific features including 1dB detented gain controls for easily repeatable settings and a custom security cover for tamper-proof installations. Active Inrush Limiting eliminates AC inrush current, cutting the need for power sequencers.

The CX amplifiers also include an HD-15 Data Port connector to interface with QSControl, QSC's computer-controlled audio system, that allows remote amplifier monitoring and control via a standard Ethernet network.
