Xvive Audio XVU3C SET Reviews

Makes my job easier

By Vance
Rated 5 out of 5
Date: 2024-06-14

I use this for a podium mic at church where a cable is impractical. The receiver is plugged into the mixer about 50 ft away behind a wall/window. Using 12V, there is a good, strong connection. I tested the mic 80 ft away behind another wall with no loss of signal. Sound reproduction is good and no RF interference so far. Cons: No indication of battery level, and I have to disconnect them and move them to a place where I can charge them.

Good but 2 points of caution

These are really easy to use. Sound is mostly very clear. Occasional interference is usually solved by switching channels. FIRST: The range is NOT 90'. Not even close. Beyond 15-20' you will get distortion, always! SECOND: Caution attaching to certain camcorders (Canon XF400, certain Sonys). If the XLR release is a simple push toward the receiver, DO NOT USE IT. Use only with releases that push in to the XLR port. Because the receiver body is wide, it will lock on the first type and be unremovable forever. I had to file a $500 insurance claim for one that got stuck onto a Canon MA-400.

Yes, the XVive U3C Set Wireless Plug-On System for Condenser Microphones will be compatible with condenser microphones, however it will need some sort of adapter in order to be fully compatible with the Z8. You will need to use an adapter like B&H # KOLMT100.

About how long of battery life do you get when using 48V Phantom Power?
Asked by: Andrew
The Xvive Audio U3C Set Wireless Plug-On System for Condenser Microphones (2.4 GHz) internal battery in both the transmitter and the receiver lasts for 5 hours. Both units can be easily charged at the same time using the included dual-USB cable and any standard 5V USB charger—and charging takes between 1.5 and 2.5 hours depending on the current of the charger being used.

Can U3C be used even with a dynamic microphone that doesn't need phantom power with phantom power switched off?
Asked by: Rathnakar
The Xvive Audio U3C Set Wireless Plug-On System for Condenser Microphones is only meant for condenser microphones, and the manufacturer specifically advises against connecting dynamic microphones to this system. It does not appear that phantom power can be switched off on this version and therefore has the potential to damage dynamic microphones.
