Zaxcom TRXFB3

Description

Zaxcom TRXFB3 wideband wireless microphone transceiver with internal recording, headphone monitoring and NeverClip, 2x AA battery compartment

The TRXFB3 is a wide-band transmitter featuring the new Zaxcom High Density (ZHD) Modulation. ZHD Modulation allows up to 10 channels of wireless to be operated in only 1MHz of spectrum space. Channel spacing will vary based on the receiver you pair it with. The wireless signal is only 50KHz wide and can be spaced as close as 100KHz channel to channel allowing up to sixty channels of ZHD wireless in a single 6MHz 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.

The TRXFB3 paired with any Zaxcom wireless receivers in Mono or XR modes can be spaced as close as 400KHz channel to channel

The TRXFB3 paired with any Zaxcom QRX235, QRX200 or QRX212 in ZHD 96 mode can used in dual mode and be spaced as close as 400KHz channel to channel

The TRXFB3 paired with any Zaxcom QRX235, QRX200 or QRX212 in ZHD 48 mode can used in single mode and be spaced as close as 200 KHz channel to channel (300KHz recommended)

The TRXFB3.5 covers channels 26 through 38 (512 to 614MHz) and the TRXFB3.6 covers channels 36 through 49 (596 to 698MHz)

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 over ZaxNet’s 2.4GHz 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.

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 feature PowerRoll.

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.
