• Capable of providing up to 5,000W continuous and 8,000W peak with 

70V / 100V direct drive on the CXD4.3Q and CXD4.5Q.

• Flexible Amplifier Summing Technology

™

 (FAST) permits total amplifier 

power to be distributed across one, two, three or all four channels.

• With redundant Ethernet jacks, the CXD-Q amps seamlessly integrate with 

Q-Sys providing audio streaming directly to and from the amplifiers.

• Version 4.0 of Q-Sys designer includes the CXD-Q amps in the 

inventory and provides complete system wide design, as well as 
control and monitoring capability.

• GPIO connectors on Euroblock enable additional functionality 

utilizing the intuitive and powerful Q-Sys control engine complete 
with logic functions and LUA scripting.

• Input Euroblock connectors and touch-proof Euroblock  

loudspeaker connectors.

• PowerLight universal switchmode power supply with Power Factor 

Correction for highest efficiency, improved audio performance, 
and low weight.

• Built-in energy saving modes ensure that the amplifier will 

draw the minimum amount of AC power while still providing 
outstanding audio quality.

Network Amplifiers – CXD-Q Series

Designed specifically for use with the Q-Sys Networked Audio System,  
CXD-Q amplifiers marry the exciting new amp technology found in the 
CXD/PLD platform with the powerful Q-Sys network processing and 
control system to create the perfect solution for installed applications.  
The CXD-Q line includes three models (CXD4.2Q, CXD4.3Q & CXD4.5Q) 
capable of delivering robust, high-fidelity power to drive a wide range of 
loudspeaker configurations including 70V and 100V systems. By simply 
connecting the amplifiers via standard layer 3 Ethernet, the Q-Sys Core 
can route audio to/from the amps, as well as provide total control and 
monitoring of all amplifier functions.  Flexible Amplifier Summing 
Technology

™

 (FAST) actively distributes total amplifier power across one, 

two, three or all four outputs enabling amp channels to be paralleled or 
bridged for maximum current and voltage output.
