File Storage
Proprietary .mic files generated by the A10-TX-US are stored on FAT32-formatted microSD
cards. The microSD card slot is located in the battery compartment and is accessed by removing
the battery nearest the display.
If no microSD card is inserted in the unit, a ‘No card detected’ message is indicated.
New cards, or cards with material that can be overwritten, can be formatted in the A10-TX-US.
ª Formatting deletes all existing recordings present on the card.
There is no provision to manage files from the A10-TX-US. File management, including file
renaming and individual file deletion, is done when the microSD card is mounted to a computer
via a card reader.
File Conversion .MIC to .WAV
The .mic files generated directly on the A10-TX-US are not usable until converted. Audio Ltd.
provides a free Mic2Wav conversion utility, available for download from the Audio Ltd. website:
www.audioltd.com . This utility—available for Mac or Windows operating systems—converts
.mic files to usable Broadcast WAV files.
Timecode and Time-of-Day Clocks
The A10-TX-US includes high-precision internal clocks to maintain time-of-day/date and
SMPTE timecode. These clocks run continuously when AA batteries are in the unit and draw
negligible current (less than 1 uA). The A10-TX-US design incorporates a supercapacitor to
power the time-of-day clock for several days in the absence of batteries. The supercapacitor
reaches full charge when batteries have been in the unit for five minutes.
Time-of-Day Clock
The time and date clock holds time and date for files recorded on the A10-TX-US, and can be
used for the Time of Day timecode value.
To set time and date:
1. Enter the Selection Menu option real time clock. ( Menu > System > Set Time/Date )
2. Use the center Menu button to move between year, month, day, hours, and minutes. Use
the Left and Right buttons to change the values.
3. Press the center Menu button to select the Return arrow and view current values. Press
again to exit.
External LTC Jamming
External LTC timecode can be applied to the A10-TX-US to synchronize its internal timecode
clock. Synchronization of timecode clocks is called “jam syncing”. To jam the A10-TX-US
timecode clock, navigate to Menu > Record/TC > Timecode in the Selection menu . Connect
an LTC timecode source to the 3-pin LEMO
™
input connector using either the AC-TCLEMO
or AC-TCBNC-IN cables. The A10-TX-US will jam its timecode clock from the incoming
timecode signal.
ª While in the Timecode menu, RF transmission and recording are deactivated on the
A10-TX-US.
The timecode clock remains accurate when the transmitter is powered or in standby mode.
When the unit is powered down accurate timecode is held for six hours. After six hours the
timecode clock is reset to its default value.
