Internal Recording - Ordered as TRX901
The TRX800′s 96 hour, 24 bit internal loop-recording option is perfect for those times when there’s a lack of available frequencies or when drop-outs cannot be tolerated.  The audio is timecode referenced, recorded on and played back from a removable MiniSD memory card that can be used in any standard SD card reader.

The audio is automatically recorded full bandwidth as a .ZAX file. The included ZaxConvert file transfer software (available for both MAC and PC) utilizes sample rate conversion to obtain the sample rate and bit depth of choice when files are imported to your computer. There are two timecode stamped file types to choose from: BWF (Broadcast Wave Format) or MP3 (MPEG-1 Audio Layer 3). MP3 files are great for quickly transferring files over the internet to a transcription house.

Any number of versions of the same recording can be made from a single file.
