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. WiFi Antenna
Ensure antenna is connected securely before use.
3. USB Media
For connecting local media storage. Note that the USB ports are not intended for connection to mobile devices; no functionality, charging or otherwise is supported.
4. Service Port
For servicing use only.
Note: Connecting any other device here may result in damage.
5. Ethernet
Use to connect the CXN100 directly to a network router. Use a wired connection for seamless playback of high-resolution 352.8kHz, 384kHz, and DSD 256.
6. 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 here.
7. USB Audio In
A USB B type socket to enable connection to PC and Mac computers.
Note: For Class 2 USB audio, Windows-based PCs require a Cambridge Audio USB driver to be installed before connection. You can find the latest USB driver here.
USB Ground Switch
Note: The ground switch position should be set to 1 as default. Use another position if a humming noise occurs.
Position 1 – Normal/default position. The main unit audio ground is lifted from chassis earth.
Position 2 – USB Audio ground is lifted from the main unit audio ground, which is also lifted from chassis earth. This may be useful to reduce hum and noise that can occur with some USB Audio setups.
8. WiFi/Bluetooth Antenna
Ensure antenna is connected securely before use. Bluetooth functionality won't be possible if this antenna is not connected.
9. Chassis Ground Switch
Position 1 – Normal/default position. The main unit audio ground is lifted from chassis earth.
Position 2 – Main unit audio ground is connected directly to chassis ground. For some setups, this can reduce hum or noise when certain TVs, Turntables, and other equipment are connected to the CXN100 unit.
10. Digital Inputs (Coax and Optical)
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: If a digital input is connected to a TV, you can enable TV mode in the sources settings of the StreamMagic app. This mode minimises lip-sync delays on the audio path by bypassing MQA decoding and also reduces the chance of dropouts and glitches from some TVs.
11. Digital Outputs
TOSLINK and S/P DIF coaxial digital outputs.
12. Line Output
Line Output (fixed or variable) used to provide a signal to another amplifier or a recording device.
13. 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).
