Rear Panel Connections

 

1. AC Power Socket
Once you have completed all connections to the amplifier, plug the AC power cable into an appropriate mains socket then switch on.

2. USB Sockets
Pre-fitted Wi-Fi dongle and connection for USB HD/flash disk or optional BT100 Bluetooth audio receiver.

The USB ports are not intended for connection to Apple mobile devices, no functionality, charging or otherwise, is supported.

The Wi-fi dongle is pre-fitted. Your unit will default to an Ethernet connection if one is made, however it is advised to remove the Wi-Fi dongle if using an Ethernet connection.

If you are using this CXN (V2) with Wi-Fi please make sure your unit is positioned within range of your wireless router.

Important Note: Do not connect/disconnect the Wi-Fi dongle when the unit is on.

3. Ethernet
Use to connect the CXN (V2) directly to a router.

4. Digital Inputs (D1 and D2)
TOSLINK and S/P DIF coaxial digital inputs.

Coaxial – Use a high quality 75 ohm digital RCA Phono interconnect cable (This is different from an analogue audio phono interconnect). This input is suitable for 16-24 bit content up to 192kHz.

TOSLINK Optical – Use a high quality TOSLINK fibre optic interconnect cable designed specifically for audio use. This input is suitable for 16-24 bit content up to 96kHz (TOSLINK is not recommended at 192kHz sampling rates).

Note: To obtain the best results from your system we recommend using only high-quality Cambridge Audio interconnects. This will ensure that you hear your system as we designed it. Please ask your dealer for details.

5. Digital Outputs
TOSLINK and S/P DIF coaxial digital outputs.

6. USB Audio In
A USB B type socket to enable the playback of audio from a computer running either Microsoft Windows or Apple Mac OS X operating systems. Some builds of Linux are also suitable.

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.
