Usb Audio Connection (Cxa80 Only); Advanced Usb Audio; Use With Pcs; Use With Macs - Cambridge Audio CXA60 User Manual

USB audio connection (CXA80 only)

The CXA80 USB input enables the playback of audio files or streamed
programme from Microsoft Windows or Apple Mac OS X personal computers
(and some Linux builds). When connected via USB the personal computer will
identify the CXA80 as an audio device. Specifying the CXA80 in the computer's
audio control panel will enable it to play audio data either stored locally on the
computer or streamed to the computer via a network or the internet.

Always turn the volume to minimum, switch to another
input or turn the CXA80 off before plugging/unplugging
cables to the USB input or whilst booting up/shutting
down your PC/Mac.
Note: 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.

Advanced USB audio

The CXA80 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 CXA80 as if it were a USB 2.0 or 1.1 device.
The CXA80 also supports two USB Audio protocols (not the same as the
port types themselves) USB Audio 1.0 (which works over USB 1.1 ports and
supports up to 24-bit/96kHz) or USB Audio 2.0 (which requires a USB 2.0 port
and can support up to 24-bit/192kHz).
The default configuration is USB 1.1 and USB Audio 1.0 which works with
nearly all common operating systems and computer types without drivers and
supports up to 24-bit/96kHz audio, simply plug in and play.
In this configuration the CXA80 is able to work at up to 24-bit/96kHz by
declaring to your computer that it can handle any sample rate from 32kHz
to 96kHz.
However in some Windows/Mac operating system variants the operating
system itself may restrict or fix the output sample rate or re-sample the audio.
See our online guide at www.cambridgeaudio.com/USB-Audio on USB
Audio for more details on this. With careful choice of playback software and
settings many pitfalls can be avoided.
In particular our free Windows USB Audio 2.0 driver (available from our
website) supports up to 24-bit/192kHz audio and WASAPI Exclusive or ASIO
modes that can give enhanced performance.
USB mode can be selected in the Setup menu. 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.
A4 on – Puts the CXA in USB Class 2 mode.
A4 off – Puts the CXA in USB 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.

A brief explanation of your choices are below:

Use with PCs

With the CXA80 switched to USB Audio 1.0 (this is the default setting) the
CXA80 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 CXA80 switched to USB Audio 2.0 the CXA80 needs the Cambridge
Audio USB Audio 2.0 Driver to be loaded and can then accept up to
24-bit/192kHz (and support ASIO and WASAPI Exclusive if required).
The driver is available from www.cambridgeaudio.com/USB-Audio. The
CXA80 requires the driver version v1.67 download for USB Audio 2.0.

Use with Macs

No extra drivers are required. With the CXA80 switched to USB Audio 1.0 the
CXA80 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 CXA80 switched to USB Audio 2.0 the CXA80 works with the native
Mac OS-X 10.5 (Leopard) or above Audio 2.0 driver and can accept audio up
to 24-bit/192kHz.

Use with Linux

For most builds of Linux with the CXA80 switched to USB Audio 1.0 the CXA80
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 2.0 for which the
CXA80 should be switched to Audio 2.0 to accept audio up to 24-bit/192kHz.
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.
Optional BT100 for bluetooth audio streaming (not
supplied)
When connected to your CXA, this adaptor allows the CXA to receive
Bluetooth Audio (known as Bluetooth Advanced Audio Distribution Profile or
A2DP). Contact your dealer for details.
This should be inserted into the USB socket marked BT100 (as shown below)
on the rear panel whilst the CXA is off. You can now turn the CXA on and select
the Bluetooth buttons on the front panel or on the remote control.
