I am not too sure how I missed the launch of this fabulous piece of equipment,because now I know what I want for Christmas.This past September Zaxcom came up with something beyond fantastic
"a new recording wireless transmitter that supports two microphone inputs and independent transmission of two isolated audio channels". The numerous options that this opens up for any location mixer simply bugles my mind. Below is all of the info I could find:
TRX900LTS (LTS), a new recording wireless transmitter that supports two microphone inputs and independent transmission of two isolated audio channels, all on a single RF carrier signal. This revolutionary new product will allow for the first time ever audio professionals in the television broadcasting, live event, sporting, and theater markets to transmit a stereo image wirelessly from talent via a single body pack. Available in October 2010, the LTS’ unique dual-microphone input greatly enhances the production of 5.1 surround sound.
“Our new LTS two-channel recording wireless transmitter is ideal for any type of wireless audio production where a stereo image, with its clear right/left perception of audio, will enhance the sound track,” said Glenn Sanders, Zaxcom's president. “As a lightweight bodypack with no heat generation and a six-hour run time on just one AA lithium battery, the LTS is likely to be very popular with both production staff and talent alike. Users even have the option of switching the LTS to single-channel transmission, ensuring flexible production options no matter what audio needs our customers face.”
Incorporating the key functionality of Zaxcom’s patented wireless-recording technologies, the LTS records timecode-stamped, two-channel, back-up audio directly within the body pack to eliminate the risk of audio loss due to interference or signal drop out. With 100-percent digital audio wireless transmission and no intermodulation, the LTS provides superior audio quality that rivals that of a hardwired connection. Each unit also features an internal SMPTE timecode reader/generator. The LTS provides up to 96 hours of recording time, and is supported by the ZaxNet remote control network for easy adjustments on-the-fly.
The TRX900LTS is also fully compatible with ZaxNet, Zaxcom’s new 2.4-GHz RF network that enables the distribution of remote control signals, timecode, IFB audio, and metadata. With ZaxNet, LTS users can remotely control gain settings and replay audio via a timecode reference giving production sound mixers the ability to replay and remix audio, creating a virtual multi-track playback and re-record system.

More on Internal Recording
The TRX900LTS' 96 hour, 24 bit internal recording 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 MicroSD memory card that can be used in any standard SD card reader.
Audio can be recorded, played back and timecode referenced either manually or through remote control commands from the IFB100 transmitter.
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.

It is absolutely impossible to have a bad recording with these-placement nor RF drops are no longer an issue. Now if only the price was less revolutionary....
