IMPORTANT
The formatting of the MTCR SD card sets up contigu-
ous sectors for maximum efficiency in the recording
process. The file format utilizes the BEXT (Broadcast
Extension) wave format which has sufficient data space
in the header for the file information and the time code
imprint.
The SD card, as formatted by the MTCR, can be cor-
rupted by any attempt to directly edit, change, format or
view the files on a computer.
The simplest way to prevent data corruption is to copy
the .wav files from the card to a computer or other Win-
dows or OS formatted media FIRST. Repeat – COPY
THE FILES FIRST!
Do not rename files directly on the SD card.
Do not attempt to edit the files directly on the SD card.
Do not save ANYTHING to the SD card with a comput-
er (such as the take log, note files etc) - it is formatted
for MTCR use only.
Do not open the files on the SD card with any third
party program such as Wave Agent or Audacity and
permit a save. In Wave Agent, do not IMPORT - you
can OPEN and play it but do not save or Import - Wave
Agent will corrupt the file.
In short - there should be NO manipulation of the data
on the card or addition of data to the card with anything
other than a MTCR. Copy the files to a computer, thumb
drive, hard drive, etc. that has been formatted as a
regular OS device FIRST - then you can edit freely.
iXML HEADER SUPPORT
Recordings contain industry standard iXML chunks in
the file headers, with the most commonly used fields
filled in.
Installing the Card
The card slot is covered by a flexible cap. Open the cap
by pulling out on the side flush with the housing.
Pull up on this side of cap to open
Insert the card with the
label facing the keypad
side of the recorder.
Formatting the SD Card
New microSDHC memory cards come pre-formatted
with a FAT32 file system which is optimized for good
performance. The MTCR relies on this performance and
will never disturb the underlying low level formatting of
the SD card. When the MTCR “formats” a card, it per-
forms a function similar to the Windows “Quick Format”
which deletes all files and prepares the card for record-
ing. The card can be read by any standard computer
but if any write, edit or deletions are made to the card
by the computer, the card must be re-formatted with
the MTCR to prepare it again for recording. The MTCR
never low level formats a card and we strongly advise
against doing so with the computer.
To format the card with the MTCR, select Format Card
in the menu and press MENU/SEL on the keypad.
NOTE: An error message will appear if samples
are lost due to a poor performing “slow” card.
WARNING: Do not perform a low level format (com-
plete format) with a computer. Doing so may render the
memory card unusable with the MTCR recorder.
With a windows based computer, be sure to check the
quick format box before formatting the card.
With a Mac, choose MS-DOS (FAT).
