Q: I’ve copied several files from my PC onto a Compact Flash card, but I can’t get a
directory listing, either via the serial command or FTP.
A
: The Compact Flash card may have been pre-formatted in a way, which is
incompatible with the AM-4’s operating system. Format the media in the AM-4
Digital Audio Machine, and then re-copy the files.
Q: I have several files on my AM-4 Digital Audio Machine. When I try to play one
of them, a different file plays.
A: All file names and numbers must be unique. You cannot have, for instance, two
files named SND00005.MP3, or have a file named SND00003.MP3, along with a
PLY00003.LST. The Compact Flash could also be fragmented, in which case you
need to format it in the AM-4 and re-copy the files.
Q: I have created a playlist using Windows, but it doesn’t work on the AM-4.
A: Windows sometimes uses its own filename extensions, or adds extensions that are
hidden when viewed in Windows Explorer. Try using a DOS shell, and renaming the
file, or use a DOS editor actually create the file.
Q: I’ve done all the stuff listed in the Copying Files section to get sound files into
my AM-4 Digital Audio Machine, but it just won’t play them.
A: Did you ever use Windows instead of DOS to copy the files over? If so, reformat
the Compact Flash in the AM-4 Digital Audio Machine, and go back through the
steps.
Q: Can I control the AM-4 Digital Audio Machine with your show controller?
A: Yes. There exists a protocol file specifically designed to operate the AM-4.
Q: What brands of Compact Flash Cards do you recommend? Where do I get one?
A: We don’t have a brand we endorse, but we know cards from SanDisk and Simple
Technology work in the units. You can typically get them from a local camera shop,
computer supply store, or online. They need to be ATA compatible. Also check our
Knowledge Base at http://www.alcorn.com/kb/index.html. Type in Compact Flash to
see if we have added anymore to our list.
Q: I press the test button and no file plays, but I’m sure I put files on there.
A: Did you name the files correctly? Did you copy the files via DOS? Can you see
the files using AMI Explorer? Are they valid audio files?
Q1: I hear parts of one file while I’m playing another.
Q2: I hear popping or blank spots in my audio playback.
A: Your Compact Flash card is fragmented. Format the card in the AM-4 and re-
copy the files back onto it.
