The TRXFB3 is a wide-band transmitter featuring the new Zaxcom High Density (ZHD) Modulation. It’s
packed full of features we invented to make your life on set the best it can be - built-in recording with
timecode, ZaxNet remote control - so there’s never a need to get near talent - and crystal clear 100%
digital transmission that rivals a hard wire.
You might be wondering what makes this unit special... It’s a reincarnation of a feature we had to bring
back by popular demand. This single body pack transmits audio via UHF and receives an IFB audio feed
received over ZaxNet’s 2.4 GHz signal at the same time. It replaces the need for talent to wear both a
wireless microphone pack and an IFB receiver.
There's also a key at the top of the transceiver that's user programmable. Currently it can be assigned as
a push to mute or a push to talk key. If you'd like it to be something else, just call the factory and we can
most likely program the key to meet your specific needs.
The TRXFB3.5 covers blocks 20 through 23 (512-614MHz) and the TRXFB3.6 covers blocks 23 through 26
(596 - 698 MHz). It's lightweight and durable, housed in a high strength, impact resistant nylon polymer
casing. The FB3 has NeverClipTM for an incredible dynamic range and also utilizes Zaxcom's battery saving
feature PowerRollTM. PowerRollTM automatically adjusts the transmitter output power based on the
record status as sent via ZaxNet boosting the output power level up to 100 mW while rolling and
powering down to 50 mW while on standby.
The FB3 works with ZaxNet, Zaxcom’s 2.4-GHz RF network that distributes remote control commands,
timecode and IFB audio. With ZaxNet, one can remotely control transmitter settings such as gain,
frequency channel selection, transport controls and output power levels. When paired with an
IFB100/200 and Deva or Fusion the units can also 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.
The FB3 also sends a Quality Control audio signal over ZaxNet so when micing someone you don't have
to go to the cart to hear how it sounds. Now you can use an ERX to listen to the mic right on the spot.
