The Control Bus allows any compatible Cambridge product to synchronise when powering up the units. See the following diagrams when connecting the EXA100 using the provided Control Bus cable.
Another added feature with this Control Bus is the use of the StreamMagic app. You can use the StreamMagic app to control the EXA via the EXN.
As well as the EXN100, the EXA100 is also compatible with the CXN100 and CXC via Control Bus.
StreamMagic app (via EXN100)
When using the app to turn the EXN on/off, this will also turn the EXA on/off. The app can also be used to control the volume of the EXA. Connect the EXN Control Bus out to EXA in.
If you wish to control the volume of your EXA via the SM app, please ensure that the 'Pre-amp' mode is disabled and the 'Control Bus' has been set to 'Amplifier' in the app device settings.
EXA100 with CXC
When turning the EXA on/off, this will also turn the CXC on/off. Connect the EXA Control Bus out to CXC in.
EXA100 with EXN100
Note: Without using the StreamMagic app to control the EXA.
When turning the EXA on/off, this will also turn the EXN on/off. Connect the EXA Control Bus out to EXN in.
EXA100 WITH EXN100 AND CXC
When turning the EXN100 on/off, this will turn the EXA and CXC on/off.
With all three devices, connect the EXN100 Control Bus out to EXA Control Bus in. Then connect the EXA Control Bus out to CXC Control Bus in.
Note: Do NOT loop back from the CXC Control Bus out to the EXN100 Control Bus in.
Control Bus will also need to be enabled and set to Amplifier within the device settings in the StreamMagic app once the app has been connected to the EXN100.
Note: If a device with Automatic Power Down (APD) enabled automatically switches off after the selected period of inactivity, this will also switch off the other connected devices.
