MICROPHONE CONNECTIVITY<\/h4>\n

The TRX743\u2019s cones are easily swapped in the field for ultimate flexibility. It comes standard with one cone of your choice, extra cones can be purchased seperately.<\/p>\n

Cone choices:
\nMono Analog \u2013 3-Pin XLR
\nStereo Analog \u2013 5-Pin XLR
\nAES (not powered) \u2013 3-Pin XLR
\nAES42 (powered) \u2013 3-Pin XLR<\/p>\n

ENCRYPTED AUDIO<\/h4>\n

The TRX743 transmits using 100% digital modulation allowing audio to be fully encrypted. Digital encryption is the only way to keep all audio transmission private. A digital transmission also provides audio quality superior to analog systems.<\/p>\n

QC AUDIO TRANSMISSION<\/h4>\n

The TRX743 also sends\u00a0a Quality Control audio signal over ZaxNet\u2122, so\u00a0when micing someone you don\u2019t have to go all the way to the cart to hear how it sounds, you can use an\u00a0ERX to\u00a0listen to the mic right on the spot.<\/p>\n

NEVERCLIP\u2122<\/h4>\n

NeverClip\u2122 is a standard feature of the TRX743 and works with all mono transmission types. It works by utilizing two A-D converters to extend the dynamic range of the transmitter to 126 dB, so there\u2019s never any limiter distortion.<\/p>\n

INTERNAL RECORDING<\/h4>\n

Audio is simultaneously transmitted and recorded to a removable microSD card using the highly reliable MARF (Mobile Audio Recording Format) which eliminates file corruption common to recordings due to a dead battery or early card removal.<\/p>\n

ZAXNET\u2122<\/h4>\n

TRX743 is equipped with ZaxNet\u2122, a long-range remote-control system allowing the user to change the frequency, pre-amp gain, sleep mode, and place the internal recorder in record, playback, and stop modes \u2013 all without ever needing to disturb talent.<\/p>\n

The units can also replay audio via a timecode\u00a0reference, giving production sound mixers the ability to replay and remix audio, creating a virtual\u00a0multi-track playback and re-record system.<\/p>\n

POWERROLL\u2122<\/h4>\n

To extend battery life, PowerRoll\u2122 adjusts the TRX743\u2019s power level to 100mW when the audio received from it is being recorded by a ZaxNet\u2122 compatible recorder. When the transmitter audio isn\u2019t being recorded the power is automatically reduced to 25mW.<\/p>\n

MODULATION CHOICES FOR YOUR ENVIRONMENT<\/h4>\n

The range will always vary depending on your environment, but you\u2019ve got choices to optimize transmission for peak performance. Zaxcom High Density modulation (ZHD) increases the number of available channels from 4 to 9 for every 1 MHz of spectrum space, perfect for reflective environments like busy city streets. XR gives you the maximum distance in less dense \/ more controlled spaces.<\/p>\n

POWER<\/h4>\n

The TRX743 runs on 3 x AA battery cells, the runtime is completely dependent on battery type and the power requirements of the microphone you\u2019re using.<\/p>\n

MHZ BANDS<\/h4>\n

TRX743 is available in the following frequency bands:
\n\u201c.5 band\u201d (512-608 MHz)
\n\u201c.6 band\u201d (578-698 MHz) (not available in the U.S.)<\/p>\n
