Chapter 3_______________________________________Zaxcom Digital Wireless System User’s Manual42Chapter 3 – Recording Audio using the Digital Wireless System TransmittersThe ability to record audio at the transmitter is an optional feature, which must be configured by Zaxcom whenpurchased. If the necessary configuration steps have not been performed, none of the recording features will beavailable.Recording FormatThe MiniSD card is formatted using the FAT32 file system. While recording, the transmitter places all recordedaudio in a single file on the media.The FAT32 file system can be read on both Windows and Mac OS computers. However, the single file generatedby the recorder can only be understood by the Zaxcom Transfer and Conversion utility. It converts the fileinto a format (Broadcast Wave Format = BWF), that is useable in Post. This utility is available to anyone for freefrom the Zaxcom website.Recording ModeThe audio can be recorded in Loop Recording mode or Non-Loop Recording mode.In Loop Recording mode (indicated by LREC in the Pacifier page), as the card fills-up, it eventually loops backto the beginning of the card and records over the oldest material. To prevent audio from being erased, do notexceed the recording length of the media (see Table 3.1 – Available Recording Time).In Non-Loop Recording mode (indicated by REC in the Pacifier page), as soon as the card is full, recordingceases and the screen displays FULL.Battery LifeWhile recording audio, a slight decrease in battery life occurs.
