If you experience any trouble with your Evo, visit the help section on our webpage at

If you have trouble connecting the Evo to your network, these steps may help to resolve the problem:
• Confirm that a connected computer can access the Internet (i.e. can browse the web) using the same network.
• If you have an encrypted Wi-Fi network, check that you have entered the correct key or passphrase. Remember that text-format keys are case-
sensitive.
If your Evo can connect to the network successfully but is unable to play particular Internet Radio stations, it may be due to one of
the following causes:
• The station is not broadcasting at this time of the day (remember it may be located in a different time zone).
• The station has reached the maximum allowed number of simultaneous listeners.
• The station is not broadcasting anymore.
• The Internet connection between the server (often located in a different country) and you is too slow.
If you have problems with UPnP playback check the following:
• Ensure your chosen UPnP server software is capable of serving the file type you are trying to access. Some servers do not serve FLAC for instance.
• Evo can only play non DRM files. Files that have DRM controls cannot be played by Evo. Some servers may be able to authorise and de-crypt
Microsoft PlaysForSure before then serving the content to Evo, but this operation is not guaranteed as it is purely a function of the server.
• If attempting to play 24-bit WAV or FLAC content a wired Ethernet connection is normally required for reliable operation due to bandwidth
considerations.
• Check Evo is capable of playing back the file type you are trying to access.
If you have problems with USB Media playback check the following:
• Check Evo is capable of playing back the file type you are trying to access.
• For USB Media Evo can only play non DRM files. Files that have DRM controls cannot be played.
• Check that your device does not require more than 1A if it is powered from the USB socket itself.
• Check your device format is supported by Evo.
• The way you organise your USB media affects how efficiently Evo can browse the content. A good practice is to create folders for Artists within
which you should have subfolders for each Album which then contain the tracks for that Album. Libraries with thousands of tracks in one folder will
progressively slow down Evo's media browsing.
A TV connected to a digital input has dropouts, glitches or disrupted audio.
• Some TVs have been found to have issues on digital inputs. Enabling TV mode in the StreamMagic app for the digital input connected to a TV
should reduce the chance of audio issues from the TV.
MQA tracks do not display as MQA on the front panel.
• If you are using one of the digital inputs, check that TV Mode is disabled.
There is no power:
• Ensure the AC power cord is connected securely.
• Ensure the plug is fully inserted into the wall socket and is switched on.
• Check fuse in the mains plug or adaptor.
There is no sound:
• Make sure the unit is not in Standby mode.
• Check that the source component is properly connected.
• Check that your speakers are properly connected.
• Make sure Evo is not in mute mode.
There is no sound on one channel:
• Check speaker connections.
• Check interconnects.
There is a loud buzz or hum:
• Ensure no interconnects are loose or defective.
There is weak bass or diffused stereo imaging:
