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 stick
is attached. USB file audio is not sent to encoders and cannot be transmitted via an
audio stream to another codec.
·
The USB stick can be inserted or removed at any time as long as the codec is not
already playing audio in failover mode. Removing the USB stick 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 reliably 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.
