Troubleshooting Guide
Q:
Using the discrete inputs, the front panel LEDs do not turn on and the unit does not play.
A
: Verify that the Voltage/Contact Closure setting is properly configured.
Q:
I’ve copied several files from my PC onto a Compact Flash, but they do not play.
A
: The Compact Flash may have been pre-formatted in a way that is incompatible with the
ProTraXX operating system. Be sure you have saved your files, then format the card as
Microsoft FAT32.
Q:
Audio playback is too fast or too slow.
A:
All files played on the ProTraXX must be encoded to use the same sample rate (i.e all
44.1KHz or all 48KHz, etc.). You cannot mix and match sample rates.
Q:
I hear snaps and pops in the playback audio, especially when playing all of the channels.
A:
Make sure that your maximum encoded bitrate is no greater than 192kbps if playing 8
stereo files and 128kbps if playing more than 8 simultaneous files. If playing more than 8
files at once, please verify that they are mono files. ProTraXX supports a maximum of 8
stereo mp3s, or 16 mono.
