Notes:
Always use a high-quality USB connection cable certified as USB Hi-Speed. USB cable connections longer than 3m may result in inconsistent
audio performance.
Always turn the volume to minimum, switch to another input or turn the CXA off before plugging/unplugging cables to the USB input or
whilst booting up/shutting down your PC/Mac.
The use of USB hubs is not recommended for this input.
7. IR In
Allows modulated IR commands from an IR repeater or custom install systems to be received by the amplifier.
Commands received by the IR In socket are not looped out of the Control Bus.
Note: The IR input doesn’t provide any power, so any device connected to this input will need to have its own power source.
8. Control Bus
RCA sockets used to send and receive power and volume commands from other connected CX Series products. For more information on the Control
Bus, see Control Bus section.
9. Balanced Audio Output
For use with balanced XLR connections. The balanced connection is the higher quality option and can reject noise and interference in the cable
when used with other equipment that supports this function.
Note: XLR connectors should be wired as follows: Pin 1: Ground, Pin 2: Hot (in-phase) and Pin 3: Cold (phase-inverted).
10. Line Output
Line Output (fixed or variable) used to provide a signal to another amplifier or a recording device.
