TROUBLESHOOTING
Should faults occur, it is in many cases not necessary
to consult your dealer or technical service department.
On the basis of the following checks, you will be able
to rectify a number of conditions yourself without
difficulty. If the condition cannot be remedied after the
following check, please consult your dealer or contact
Marantz Professional at 630 741 0330.
The PMD670 does not turn on
Check power
• install fresh batteries
• check AC adaptor connections
The PMD670 turns on then turns itself off
• install fresh batteries
The PMD670 seems to record but there is no sound
on playback
• check input settings (For example, if LINE input is
selected and no input is connected to the LINE IN
jacks the PMD670 will record silence.)
The PMD670 will not playback
• check EDL switch, if ON switch to OFF
No audio playback through headphones or internal
speaker
• check HP/SPK VOLUME control setting
• check a different track or CF card
The PMD670 will not record
• check that the maximum of 999 tracks have not
been recorded
• check that the PMD670 acknowledges the CF
card
No signal from microphone input
• chedk input selection
• check REC level control settings
• check if microphone(s) require Phantom power
Excessive noise
• check cable connections
Playback on a PC results in poor sound
• check quality of PC sound card and program
• check frequency conversion program*
*The PMD670 records audio files with a sampling
frequency of 48kHz. Some PC programs convert
the files to 44.1kHz (using a sample rate con-
verter). Only high quality sample rate converters
should be used.
PC cannot read files
• check if the files are MP2 or MP2 with a .wav file
extension Some PC's cannot interpret this combi-
nation. Try renaming the MP2 file so it has a .mp2
or .mp3 file extension.
• check the capability of the PC program
Some playback and editing programs do not
support MP2/MP3 or Broadcast Wave (.bwf)
formats. Consult the Marantz Professional
website at www.marantzpro.com for links to
programs that support MP2/MP3 and Broadcast
Wave Format.
The rechargeable battery not recharging
• check that the CHARGE indicator is flashing
during charging and lit and steady when charging
is complete.
• check AC adaptor connections
• check that Power is turned off on the PMD670
Rechargeable battery life low
• make sure you fully charge and discharge the Ni-
Cd battery during each charge cycle
• replace battery
Media cards that are heavily used should be occa-
sionally reformatted to avoid audio problems due to
fragmentation.
If the PMD670 exhibits erratic behavior, the micropro-
cessor can be reset by, powering off, disconnecting
AC power and removing batteries.
