The TRX900LT series includes the TRX900LT, TRX900LTS, TRX900LTH & TRX900LTHS transmitters.

They combine crystal clear digital wireless transmission, a built-in backup recorder and remote control functionality via the IFB100 and/or ZaxNet into a single, low-cost system for episodic television production, motion picture and broadcast events.

Designed to be lightweight and durable, the LT Series transmitters are housed in a high strength, impact resistant nylon polymer casing that provides protection from both corrosion and water damage.

TRX900LT Series Overview

Like all Zaxcom digital wireless, the TRX900LT series features 100% digital transmission for audio quality that rivals a hard-wired system and is fully encrypted to eliminate the possibility of production audio interception and theft. They come standard with our patented internal timecode referenced back-up recorder which backs up the transmitted audio onto a removable microSD card eliminating the possibility of audio loss due to interference or signal dropout. The transmitters operate on a single AA lithium battery (run times vary by model, please see specifications) and are fully compatible with all Zaxcom wireless receivers and IFB transmitters.

The LT series is fully compatible with ZaxNet, Zaxcom’s 2.4-GHz RF network that enables the distribution of remote control signals, timecode, IFB audio, and metadata. With ZaxNet, one 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.

What sets these units apart?
The TRX900LTS is a stereo version of the LT,  two lavaliere microphones are connected via the single 3-pin LEMO connector.  A stereo image can be wirelessly transmitted from talent with a single bodypack style transmitter opening up unlimited possibilities for the enhancement of audio on programming delivered in 5.1 surround format.
The TRX900LTH is a high powered version of the TRX900LT, the output power is 25, 50 or 125 mW – user selectable.  This transmitter can utilize the battery saving feature PowerRoll™.  PowerRoll™ automatically adjusts the transmitter output power based on the record status as sent via ZaxNet boosting it up to 125 mW while rolling and powering down to 50 mW while on standby.
The TRX900LTHS is a stereo version of the high powered LTH.
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.
