The TRXFB3 is a wideband transmitter featuring the Zaxcom High Density (ZHD) Modulation with built-in recording with time code, ZaxNet remote control, and crystal clear 100% digital transmission that rivals a hard wire. This single body pack transmits audio via UHF and receives an IFB audio feed over ZaxNet’s 2.4 GHz signal at the same time, replacing the need for talent to wear both a wireless microphone pack and an IFB receiver.
A user-programmable key at the top of the transceiver can be assigned as a push to mute or a push to talk key. If you'd like it set as something else, contact us and we'll see what Zaxcom can do.
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 NeverClip for an incredible dynamic range and also utilizes Zaxcom's battery-saving PowerRoll. PowerRoll 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, time code 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 sends a Quality Control audio signal over ZaxNet so, when wiring talent, you can use an ERX to listen to the mic right on the spot.
Glenn Sanders gave Nick Huston a demo when the unit was still in the prototype phase:
ZHD TransmissionZHD Modulation allows up to 10 channels of wireless to be operated in only 1 MHz of spectrum space. Channel spacing will vary based on the receiver you pair it with. The wireless signal is only 50 KHz wide and can be spaced as close as 100 KHz channel to channel allowing up to sixty channels of ZHD wireless in a single 6 MHz American television channel. The new modulation is ultra efficient resulting in incredible transmission range.
The ZHD transmitters are capable of running existing mono Zaxcom modulations maintaining compatibility with all currently produced Zaxcom receivers. ZHD modulation conforms to all currently proposed FCC regulations for spectrally efficient wireless transmission.
CONSUMER ALERT: Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website atwww.fcc.gov/cgb/ wirelessmicrophones.
Some versions of this wireless microphone device may operate in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at www.fcc.gov/wireless-microphones-guide or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
