IFB200 Transceiver

IFB200 Transceiver

The IFB200 transmits IFB audio, timecode and remote control commands to the TRX series digital recording wireless transmitters and ERX series receivers on a single RF carrier using a 2.4 GHz signal.  It can be used license-free in almost every country.

IFB200 can be used in an array of applications – sound cart, sound bag, studio or on the side of your video camera.  It has dedicated connectors for a dual analog or AES audio input, timecode input and output, receive audio and power input.  The front has a graphic LCD screen showing timecode and transmitter status.

IFB200 Features:

  • Transmits and receives IFB, timecode and audio
  • Fully compatible with all TRX series transmitters and ZFR recorders
  • Built-in 2-channel backup recorder, perfect for small sound bags that only have a mixer
  • Analog or digital audio input on a single TA5 connector
  • AES sample rate converting input with max sample rate input of 96 KHz
  • Built-in 2-channel mixer for combining two separate channels into a mono transmission signal
  • Timecode reader / generator can run continuously jam or free run timecode
  • Software updates are done by the user via the microSD card slot
  • IFB audio range of approximately 100 feet / IFB timecode and remote control range of approximately 400 feet

IFB200 Functions:

  • Receive timecode and IFB audio from any ZaxNet transmitter
  • Monitor QC audio from your ZFR recorder or TRX transmitter
  • Monitor return audio from the QRX100 w/QIFB mounted on the camera
  • Send timecode and audio to an ERXTCD for listening to audio or to sync slates and cameras
  • Send remote control signals like gain, frequency changes, record compands or power settings to your TRX or ZFR


The backup recording on the IFB200  is a timecode stamped MARF file, this stands for “Mobile Audio Recording Format”.  MARF is a fault tolerant recording format that allows for power to be removed from the IFB200  while recording without the risk of file corruption common to recorders using the FAT32 file system.  MARF files are easily converted to .WAV or MP3 files with the use of ZaxConvert.

As an integral new addition to the family of ZaxNet compatible products, the IFB200 transmitter makes it easy to have a virtual multi-track recording (Patented).  By sending timecode from the IFB200 to any number of TRX’s or ZFR’s at the same time, each unit will have the same timecode that easily matches up in Post.
