QSC Audio has introduced the new CXD-Q network amplifier line, specifically for use with the company’s Q-Sys network audio platform.

CXD-Q models combine the Flexible Amplifier Summing Technology (FAST) found in the CXD/PLD platform with the same Q-Sys network connectivity and processing to create a powerful audio routing and power solution for installed sound applications. 

“CXD-Q represents our ongoing commitment to create installed sound solutions that are incredibly versatile and integrate seamlessly with Q-Sys,” says Dale Sandberg, QSC senior product manager. “As Q-Sys products, they operate like other Q-Sys peripherals utilising the same standard Layer 3 networking technology for audio streaming, control, and monitoring. As amplifiers, they feature our new Flexible Amplifier Summing Technology (FAST) that enables the amp channels to be combined and deployed in a wide range of installed sound applications.  This allows integrators the ability and flexibility to design and install systems in a whole new way.” 

Redundant rear-panel Ethernet jacks on the amplifiers makes Q-Sys integration as simple as connecting a standard off-the-shelf Ethernet cable.

Like other Q-Sys peripherals, adding CXD-Q amplifiers to a new or existing Q-Sys design is easily done via the Q-Sys Designer Schematic Page. In addition, the onboard Mic/Line inputs are audio on-ramps onto the Q-Sys network, providing routable inputs to anywhere in a facility. 

Housed in a 2RU package, CXD-Q network amplifiers incorporate new QSC proprietary class D power devices, which enable multi-channel, high-performance power. 

The lineup includes the CXD4.2Q (400 watts per channel at 4 ohms continuous, 500 watts per channel burst), CXD4.3Q (625 watts per channel at 4 ohms continuous, 1600 watts per channel burst) and CXD4.5Q (1250 watts per channel at 4 ohms continuous, 2000 watts per channel burst). The CXD4.3Q and CXD4.5Q able to direct drive 70- and 100-volt systems.

FAST provides better power allocation by distributing the total amplifier power across one, two, three or all four outputs enabling amp channels to be combined for maximum current or voltage output. The largest models are capable of up to 5000 watts continuous and peaks of up to 8,000 watts.

The rear panels include four balanced Euroblock mic/line input connectors that are onramps into the Q-Sys system, and four Euroblock touch-proof loudspeaker connectors enabling integrators to terminate wiring before connecting to the amplifier, while GPIO connectors offer additional functionality.

In addition to their outstanding efficiency, CXD-Q amplifiers power saving modes further ensure that energy costs will be kept to a minimum over the life of the installation.

CXD-Q Series network amplifiers will be available in April 2014.
