ADVANCED USB AUDIO

The CXA is both USB 2.0 (Hi-Speed) and USB 1.1 (Full-speed) USB port 

compatible.

It should also work with the new USB 3.0 ports where the PC will simply 

treat the CXA as if it were a USB 2.0 or 1.1 device.

The CXA supports two USB Audio protocols (not the same as the port 

types themselves) USB Audio Class 1 (which works over USB 1.1 ports and 

supports up to 24-bit/96kHz) or USB Audio Class 2 (which requires a USB 

2.0 port and can support up to 32-bit/384kHz).

The default configuration is USB Audio Class 2.

See our online guide at 

www.cambridgeaudio.com/USB-Audio

 on 

USB Audio for more details. With careful choice of playback software and 

settings many pitfalls can be avoided.

Windows based PC’s required a Cambridge Audio USB driver to be installed 

before connection. 

USB mode can be selected in the Setup menu. See 'Setup' section.

A brief explanation of your choices are below:

USE WITH PCS

With the CXA switched to USB Audio Class 1 the CXA will work with the 

native Windows XP, Vista, 7, or 8 Audio 1.0 driver (no need to load any new 

driver) and accept audio up to 24-bit/96kHz.

With the CXA switched to USB Audio Class 2 the CXA needs the Cambridge 

Audio USB Audio 2.0 Driver to be loaded and can then accept up to 

32-bit/384kHz.

The driver is available from 

www.cambridgeaudio.com/USB-Audio

USE WITH MACS

No extra drivers are required. With the CXA switched to USB Audio 1.0 the 

CXA will work with the native Mac OS-X 10.5 (Leopard) or above Audio 1.0 

driver and accept audio up to 24-bit/96kHz.

With the CXA switched to USB Audio Class 2 the CXA works with the 

native Mac OS-X 10.5 (Leopard) or above Audio 2.0 driver and can accept 

audio up to 32-bit/384kHz.

USE WITH LINUX

For most builds of Linux with the CXA switched to USB Audio Class 1 the 

CXA will work with the native Audio 1.0 driver and accept audio up to 

24-bit/96kHz.

Some very new builds of Linux are now supporting USB Audio Class 2 

for which the CXA should be switched to Audio 2.0 to accept audio up to 

32-bit/384kHz.

For both cases because Linux builds vary according to their creators choice 

of software components including drivers it is not possible to guarantee 

operation and Audio drivers may need to be loaded.

'Class drivers' as they are called for generic support of Audio Class 1.0 or 

Audio Class 2.0 devices may be available from the Linux community, we 

do not supply these.

To enter the Setup menu, put the CXA in standby mode, whilst on Standby 

mode, press and hold the Speaker A/B button until the A/B lights flash 

alternatively and the sources A1-A4 light up. See below source buttons for 

setup configuration:

Note:

 Button selected is represented by Blue light.

AUTO POWER DOWN (APD)

A1 off  – Disables the APD (Auto power down) function.

A1 on – Sets the APD time to 20 minutes.

Note:

 Auto power down is a power down function that automatically 

switches the CXA into standby mode if there is no audio. The APD time 

represents the amount of time required for there to be no audio before the 

CXA is automatically put into the standby mode.

CLIPPING FUNCTION

A3 on –  Clipping function enabled. The volume nudges down if signal 

clipping is detected.

A3 off – Clipping function is disabled. 

USB MODE

A4 on – Puts the CXA in USB Audio Class 2 mode.

A4 off – Puts the CXA in USB Audio Class 1 mode.

Notes: 

–  To save the setup settings and exit the setup menu, press the Speaker 

A/B button.

–  Pressing the Standby/On button while in the setup menu will exit this 

setup menu and will not save the setup settings.

Bluetooth

 

BLUETOOTH AUDIO STREAMING

Selecting this allows the CXA to receive Bluetooth audio from most 

phones, tablets and laptops.

PAIRING 

To begin streaming high quality music from your device it will first need 

to be paired with the CXA.Select the Bluetooth input on the CXA to enter 

discovery mode.  

Notes:

 

–  Your device can only be paired and connected to the CXA while the 

Bluetooth source is selected.

–  The CXA is always in discoverable mode when there is no Bluetooth 

connection.
