CXD-Q Amplifier Hardware

NOTE:  This topic is for reference only. Refer to the CXD-Q Amplifier User Manual for installation instructions and detail.

The CXD-Q Amplifier comes in three models CXD4.2Q, CXD4.3Q and CXD4.5Q each with different power output. The amplifier is placed in a Q-SYS design and configured for the output configuration. The inputs and outputs of the amplifier are separated in the amplifier giving you the capability of using the inputs in the same way you would use a Line Input card. In addition, you can send different audio to the amplifier's outputs than what is provided on the amplifier inputs. Of course you can connect the amplifier inputs and outputs in the design.

This topic covers the hardware aspect of the CXD-Q amplifiers. For configuration details in Q-SYS Designer, refer to the CXD-Q Status, CXD-Q Amplifier In Component, CXD-Q Amplifier Out Component, and the CXD-Q Amplifier GPIO Component topics.
