Lectrosonics SPDR Digital Recorder

Copying Recordings to a Computer:
– Remove your microSD card from the MTCR by lightly pressing inward on the card and, when released, the card should pop out of the recorder enough to remove it.
– Insert the microSD card into a microSD to SD Card adapter.
– Slide the button on the side of the adapter to the locked position and insert the adapter (with microSD card inside) into your computer’s memory card slot.
NOTE: The microSD card adapter has a write protect switch. Sliding the switch to the “locked” position prevents recording of data and protects existing data. When recording to, erasing from or formatting the microSD card, slide the switch to the “unlocked” position.
– If using a Windows operating system, the computer should detect the card and assign it to a drive. Open the selected drive by clicking on the “Start” button and select “Computer” to launch Windows Explorer, the native file manager. Open the folder that was assigned to your microSD card.
– If using a macOS operating system, the card will appear as an icon on the desktop. Double-click to open it.
– Copy the files you wish to download from the card and paste them into the selected file on your computer.
– Be sure to safely eject the card adapter when finished copying the files.

Formatting the SD Card:
SDHC cards come pre-formatted with a FAT32 file system which is optimized for good performance. The SPDR relies on this performance and will never disturb the underlying low-level formatting of the SD card. When the SPDR “formats” a card, it performs a function similar to the Windows “Quick Format” which deletes all files and prepares the card for recording. 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 SPDR to prepare it again for recording. The SPDR never low-level formats a card and we strongly advise against doing so with the computer. To format the card with the SPDR, select Format Card in the menu and press MENU/SEL on the keypad. See the SPDR Instruction Manual for details on navigating the menus. NOTE: An error message will appear if samples are lost due to a poor performing “slow” card.

IMPORTANT:
The formatting of the SPDR SD card sets up contiguous sectors for maximum efficiency in the recording process. The SD card, as formatted by the SPDR, can be corrupted by any attempt to directly edit, change, format or view the files on a computer. The simplest way to prevent data corruption is to use an adapter with a write protect switch that is set to the “locked” position (as described above). 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 computer (such as the take log, note files etc) – it is formatted for SPDR 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 SPDR. Copy the files to a computer, thumb drive, hard drive, etc. that has been formatted as a regular OS device FIRST – there you can edit freely.

WARNING: DO NOT PERFORM A LOW-LEVEL FORMAT (COMPLETE FORMAT) WITH A COMPUTER. DOING SO WILL RENDER THE MEMORY CARD UNUSABLE WITH THE SPDR RECORDER. WITH A WINDOWS BASED COMPUTER, BE SURE TO CHECK THE QUICK FORMAT BOX BEFORE FORMATTING THE CARD. WITH A MAC, BE SURE TO FORMAT AS “MASTER BOOT RECORD” AS SETTING.
