Zaxcom's VRX1 Changes the VHF IFB Receiver Game

14 February 2024

Zaxcom is pleased to announce the all new VRX1 VHF IFB audio receiver designed to monitor audio and cue talent in any number of film, television, and broadcast environments. It features an intuitive voice prompt system, voting, frame specific audio delay, an adaptive squelch, headphone equalization, and multiple power options all in a lightweight, rugged, and easy to use device.

VRX1is an advanced FM analog receiver with an innovative direct conversion design to receive audio that eliminates RF interference while extending battery life. How long? Two AA lithium batteries provide a runtime of up to 17 hours!

VRX1 operates in the VHF 192-217 MHz frequency range and comes pre-programmed with 10 industry standard channels. The unit is compatible with Comtek BST 75-216, BST 25-216, and M-216 transmitters, allowing you to mix and match VRX1 with other IFB receivers in your setup. Two push buttons control selectable channels and settings, and each button can be programmed to limit control or be completely disabled. Any of the 10 pre-programmed channels can be reconfigured using the optional Zaxcom GUI Bridge (ZGB).

A voice prompt system can announce the current channel, channel selection, battery life, and other key settings through headphones, providing a seamless interaction without needing to look down at the device. A voting feature automatically connects VRX1 to the strongest transmitter signal when more than one transmitter is in operation. Both voting and voice prompts can be disabled, if desired.

Other features include audio delay settings that can be customized for each user from 1 to 15 frames, an adaptive squelch algorithm that intelligently minimizes noise when a transmitter signal is absent or weak, and standard 3.5mm output that connects to headphones or earpieces. The 3.5mm audio output is selectable to be unbalanced or balanced allowing you to feed a single track of audio to the input of a camera. VRX1 advanced settings can be configured using the optional Zaxcom GUI Bridge (ZGB). Basic settings can be controlled both locally and through the ZGB.

VRX1 has multiple power options, including two Alkaline, NiMH, or lithium batteries. Alkaline provides up to 9 hours of runtime, NiMH up to 13 hours, and lithium up to 17 hours. Rechargeable NiMH batteries can be recharged directly through VRX1 using the USB-C port. You might be wondering if the USB-C connection can also power VRX1. That answer is a resounding yes!

Topping off the cool factor, Zaxcom also offers a VRX Dual Charger that can charge two VRX1. Simply slide them into a slot and let the VRX Dual Charger do the rest. LED indicators let you know when charging is complete.

For specification gurus, VRX1 has an RF sensitivity of .8uV for 20dB SINAD and carries an AM rejection of 90dB. VRX1 has frequency steps of 25 KHz and requires a minimum spacing of 100 KHz. The signal-to-noise ratio is 97dB and the 3.5mm output level is 2.8V max driving 16 ohms. VRX1 measures 2.46”x 4.60”x 0.640” with a weight of 4 ounces with two NiMH batteries.

VRX1 is priced at $495 and is available now at any authorized dealer. The optional EV Clip is $42 and the VRX Dual Charger is $175, both shipping.
