Playing Audio from the USB Port

A device connected to the USB HOST PORT is treated as a connection and files can be played back using the codec front panel controls.

 

1.Press the HOME home button button to return to the Home screen.

2.Select Connect, then select File and press the Ok button button.

3.Use the navigation buttons to select a file.

4.Press the Ok button button or the CONNECT connect button button to play the selected file.

5.Press the red DISCONNECT disconnect button button on the numeric KEYPAD to stop file playback.

 

Caution

Caution: Do not attach a bootable USB drive to the USB HOST PORT or the codec will attempt to reboot using the USB drive instead of the codec if the codec is repowered. To ensure any drive connected is a non-bootable drive, remove all system partitions and format the device without system startup files.

Important Notes for File Playback:

•Ensure MP3 recordings used are not variable bit rate files.

•File playback audio is sent directly to the codec outputs and therefore IGC is not available. When you create your MP2 or MP3 files ensure the audio levels match the audio reference level of your codec and that peaks average at the correct levels.

•USB backup audio is only sent to the outputs of the local codec to which a USB drive is attached. USB file audio is not sent to encoders and cannot be transmitted via an audio stream to another codec.

•The USB drive can be inserted or removed at any time as long as the codec is not already playing audio in failover mode.  Removing the USB drive while audio is playing from it will result in poor audio quality and should be avoided. If it is removed accidentally you must reboot the codec to ensure USB failover will work in future.

•If you enter a single file name ensure you add the file extension, e.g. "test.mp3", or the file will not play back.

•If you enter a directory name, all the files within the directory will be played back. We recommend you save all audio files as a playlist and link to this if you want them to play out sequentially. Please note that "M3U" is the playlist file format supported by the codec.

•File playback will occur automatically if the silence threshold parameters are breached; if the codec is not connected for any reason file playback will commence. To stop file playback open the Master panel in the web-GUI, click to select the file playback connection, then click Disconnect.
