Solution
Install fresh batteries.
Make sure PMD561's power input is properly connected
to a power outlet using the included power adapter.
Check input settings. (For example, if the line input is
selected and no input is connected to the line jack, the
PMD561 will record silence. The PMD561 will not
playback.)
Check Hp/Spk Vol control setting.
Check a different audio file or the card.
Check that the maximum of 999 files have not been
recorded.
Check that the PMD561 acknowledges the card.
Check input selection.
Check Rec Level control settings.
Check if microphone(s) require(s) phantom power.
Check cable connections and/or replace cable.
Check for proper gain levels.
Check quality of computer sound card and application.
Check frequency conversion application. (PMD561
records audio files with a sampling frequency of 48kHz.
Some applications convert the files to 44.1kHz using a
sample rate converter. Only high quality sample rate
converters should be used.)
Check the capability of the playback application. Some
playback and editing applications do not support MP3 or
Broadcast Wave (.wav) formats.
