Stock of variations of these racks are available now for various sized stereo PA systems or near field monitoring setups.
Racks will be populated with GX3/5/7 amplifiers to suit the task at hand.
Quoted from the QSC GX Spec Sheet 2011:
"The GX3 uses the latest evolution of the QSC Grounded Collector output system, for optimum cooling of the
critical power transistors. A true Class B biasing system combines maximum thermal efficiency with excellent audio
"The GX5 uses a Class H system, based on key elements of the PL Series, (PLX, PL3, CX, DCA) almost doubling power
in the same size and weight. QSC design expertise allows the output devices to shift from low-power to high-power
rails in less than a millionth of a second, ensuring that the output power is always right where it needs to be without excess loss."
"The GX7 adds the road-proven PowerLight supply to the Class H output section, for more overall output
power and additional weight savings. The result is one of the highest power-to-weight ratios in the industry. A
low-noise variable-speed fan with rear-to-front airflow keeps amplifiers and
6x way processing is provided by a DCX2496 processor.
Comes supplied with XLR patch leads and a 4x gang extension block allowing for 'plug n play' functionality in a 6U slim profile flight case.
