Note: For the balanced XLR inputs, pin1 is ground, pin2 is positive and pin3 is negative.
11. 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.
Ground/Lift switch - The Ground/Lift switch enables the USB interface earth to connect or disconnect the CXA signal ground. Disconnecting
(lifting) the earth can be useful if electronic hum is heard through the speakers when the USB input is selected. The switch should otherwise be left
in the Ground position.
12. Digital inputs (D1, D2 AND D3) - TOSLINK and S/P DIF co-axial digital inputs.
Coaxial – Use a high quality 75 ohm digital RCA Phono interconnect cable (not one designed for normal audio use). 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.
13. A1 inputs
Note: Balanced (XLR) is available on the CXA81 only.
A1 inputs feature either unbalanced (phono/RCA) or 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.
An XLR connector is wired Pin 1 - Ground; Pin 2 - Hot (in-phase); Pin 3 - Cold (phase-inverted).
