Connecting a TV

A TV can be connected to one of the digital inputs on the CXA, as long as the TV has the required Optical or Coaxial output.

Ensure that the output audio settings on the TV are set to PCM or Stereo, as the CXA is only able to decode a Stereo signal.

Please also ensure that the digital input that the TV is connected to has been selected on the front panel of the CXA (D1, D2 or D3).

Enabling ‘TV Mode’ within the CXA:

Some Connected TVs will send an inconsistent sample rate to the CXA, that the DAC inside the ampliﬁer is unable to process. This can result in

audio dropouts and glitches. If this is the case with your CXA, ‘TV Mode’ will need to be enabled within the ampliﬁer.

The serial number for your CXA61 and CXA81 will indicate whether or not 'TV Mode’ is already pre-installed or whether this will require manual

installation.

Pre-Installed (October 2020 Onwards):

The serial numbers for units that contain 'TV Mode' pre-installed are laid out as such; 'KW C11125 7060 0001'. If the third set of numbers are or are

greater than 7060, this indicates that your ampliﬁer was manufactured after October 2020 and already has ‘TV Mode’ installed.

To enable 'TV mode' on Pre-Installed units:

Enter the Setup menu by putting the CXA in standby mode.1.

Whilst in Standby mode, press and hold the Speaker A/B button until the A/B lights ﬂash alternatively and the sources A1-A4 light up.2.

See below source buttons for setup conﬁguration:

Note: Button selected (on) is represented by Blue light.

A2 oﬀ – The CXA is set to the best digital input audio setting on input D2.

A2 on – The CXA is set to a more tolerant digital input setting for input D2 that should reduce the chance of having the signal intermittently drop.

3. To save the setup settings and exit the setup menu, press the Speaker A/B button.

Note: Pressing the Standby/On button while in the setup menu will exit this setup menu and will not save the setup settings.

Uninstalled (Pre October 2020):

If your CXA pre-exists the above stated serial number combination (the third set of numbers is lower than 7060), then please contact our support

team at https://www.cambridgeaudio.com/gbr/en/contact and we will be able to provide you with instructions on how to perform this update

manually.

Please note: Your TV will have to be connected to TOSLINK OPTICAL input D2 for TV Mode to work.
