Zaxcom VRX1 VHF IFB Receiver
The Zaxcom VRX1 brings VHF IFB audio to directors, producers, and talent through any earpiece or headphones plugged into its 3.5 mm output.
It is an analog FM receiver for 192 to 217 MHz, with a direct conversion design that resists RF interference and stretches battery life. Ten standard channels between 216.025 and 216.975 MHz come preset for quick setup.
Compatibility
The VRX1 works with analog VHF FM transmitters in its range, including the Zaxcom VTX1 and the Comtek BST 75-216, BST 25-216, and M-216. It can share a transmitter with Comtek receivers already in use.
Voice Prompts and Voting
The A, B, and star buttons change settings, and each can be limited or disabled. Voice prompts announce the channel, battery level, and other settings in the headphones, so nobody has to look down at the receiver.
With voting on, the VRX1 switches to the strongest signal when more than one transmitter is on air. Voice prompts and voting can both be turned off.
Delay, Squelch, and Camera Feed
Audio delay can be set from 1 to 15 frames to match a video monitor, and an adaptive squelch quiets the output when no transmitter signal is present. The 3.5 mm output switches between unbalanced and balanced, so the VRX1 can also feed a single audio track to a camera.
Power and Setup
Two AA batteries run it for up to 9 hours on alkaline, 13 hours on NiMH, or 17 hours on lithium. The USB-C port powers the receiver and charges NiMH cells without taking them out.
The optional Zaxcom GUI Bridge (ZGB) connects over USB-C to reprogram channels and advanced settings, which makes a large inventory of receivers quicker to set up.
