The TRX992 is a completely digital transmission system optimised for boom mic operators working on motion picture and television productions, say Zaxcom. It features patent-pending internal recording that backs up transmissions to guard against lost audio files. Users can record up to 24 hours of audio to a removable mini or micro SD card using the TRX992. The system features a user-selectable power output ranging from 10mW to 100mW. Zaxcom also says that the audio dynamic range is 106dB, making the TRX992 "sound like a hard-wired microphone without any of the typical FM audio distortion problems".
The TRX992 can be used for critical monitoring applications, with a 2.4-GHz digital monitor return receiver that relays return audio, time code reference, and RF remote control commands. Alternatively, TRX992 users can choose to transmit high-resolution IFB audio instead of time code and remote control signals. As a true-diversity receiver, the TRX992 eliminates concerns over audio drop-outs, which are common to non-diversity monitor receiver systems. The system's internal monitor mixer allows users to mix transmitted audio and a monitor return together, controlled by a pan pot on the top of the unit. The TRX992 also features mic/line level input and a balanced XLR input with 48-V phantom power.
