installation applications requiring premium sound quality and high output.
Recognized by sound contractors worldwide for their reliability, CX Amplifiers
feature PowerLight
™
power supply technology reducing weight, eliminating AC
mains hum and improving audio quality. The highly efficient power supply
also draws less power and produces less heat resulting in added energy
savings. CX Amplifiers also feature advanced amplifier control and monitoring
via Q-Sys
™
network audio platform and QSControl.net.
IT-42 is an output isolation transformer accessory for the QSC CX302
