Unboxing and impressions of GMark Audio GX1.1 Digital UHF Plug-on XLR wireless mic system G-Mark

We bought this G-Mark Audio GX1.1 wireless XLR Plug-on system just for one sole purpose:- To have an always-ready, simple & basic wireless system for situations when clients suddenly throw us a curve-ball and ask for one more wireless handheld mic. We frequently shoot and provide video recordings for press conferences, panel discussions and fire-side chats at a small-scale basis, and clients will sometimes add a guest or wanted more mics for Q&A sessions. Our existing 2.4Ghz mic systems might prove to be unreliable as we're maxed out on the useable channels. (We normally run 4x Audio Technica System 10 channels with 2 bodypack and 2 handhelds, and we also run 4x Rode RodeLink wireless.) Maxing out the 2.4Ghz bandwidth is too risky. We wanted to adopt the 5.8Ghz wireless or Sennheiser AVX on DECT 1.9Ghz, but those proved to be a tad expensive. It was when we chanced upon the G-Mark wireless that we checked out the specs. Decent digital mic over UHF frequencies. Our unboxing and quick test revealed it to be quite clean, noise floor is low, audio quality is very acceptable. Range can be short, but acceptable since we are used to 2.4Ghz systems, and the other concern is only battery life since these can only be charged using USB. We'll definitely need to deploy it in real world environments before we can give it more comment. But so far, the unboxing and first impression is that it's not too shabby. Update 12 July 2026: About a month ago when we deployed 3 sets of these wireless system, we found the pairing and linking per set to be a bit of a challenge. The sequence to turn on every pair is troublesome! If you turn on the wrong order, the receiver will auto pair with other already turned on transmitter, cause a lot of grief while on stage. This problem make it worse when the itchy fingered performers like to press and fiddle with their transmitter, and cause pairing issues! When 3 receivers at plugged in paired to 3 transmitter, either one of the transmitter loses connection or gets turned off, that corresponding receiver will hop on to either one of the frequencies of the 2 transmitters that are still on! This can cause havoc and make mic assignments and channel assignments a huge mess! Do be aware of this flaw or limitation in this system! We advise to buy only if you need to use 1 set per venue as a supplement to existing professional microphone setups! Aliexpress Link: https://s.click.aliexpress.com/e/_c3u... PS: We found another desktop receiver model. https://s.click.aliexpress.com/e/_c3V... If pairing is automatic hunting, then might face same issues of using this in multiple set environment where frequencies also like to hop and lock on other transmitter units!
