Big sports events like the Superbowl have extensive frequency coordination to keep all the RF spectrum users from stepping on each other. I’m rather surprised that big events like national political conventions don’t have similar services available (or mandatory in the case of the Superbowl as I understand).
But the symptoms sound like audio gain-staging problems, not RF problems (which typically have different symptoms). OTOH, it is a rather low-end product, somewhat below the minimum “decent” example of wireless gear that is worth using (Sennheiser G3, etc.)

You can start by making double-sure that your mic cable is not broken. Do you have the option of going back to the location where the problem happened? Do you have another cable to substitute? Another mic? The usual trouble-shooting rules apply. Substitute pieces and see which one makes a difference, etc.

The Behringer SRC2496 does NOT include audio delay. And the Behringer Shark DSP110 does NOT include digital output. However the Behringer Ultracurve Pro DEQ2496 includes both adjustable delay AND digital output which is reportedly compatible with the BMD TVS digital audio input.

Inspect the nameplates on your chargers. They may be “universal” meaning that they will operate from 100 to 240V, so you would need only a mains plug adapter. Very little modern equipment gives a fig about 50Hz vs. 60Hz mains frequency.
Do you have time to get 220V versions of your bulbs? By simply substituting the bulb and using the cord plug adapter, 240V use isn’t a big deal.

“Huh? Which converter boxes are you talking about? BMD’s mini and OpenGear converters are the cheapest there is, at least from what I can find. Far more inexpensive than AJA, for instance.”
They are all overpriced based on the contents of the device. PC keyboards used to cost $250. They now cost more like $8. That is called “economy of scale” and “market maturity”.
The HyperDeck Shuttle for example is priced at $345. Now there is a lot of firmware and custom mechanical parts in that product and I think BMD is selling them for a great price. But the “Heavy Duty” mini-converters with half the technology, and no firmware are the same price.
Juet sayin’. I expect that some Asian vendor will be the first to offer these kinds of things at around $100-150 (or even less). Other examples of even more complex products of the same scope sell for a fraction of the $200-300 average we still see in the digital video world. Just because of where we are in the era and because it is perceived that is what the market will bear.

Phantom power on an unbalanced (2-terminal) connection, (if one can even manage such an abortion) will FRY any dynamic or ribbon microphone. Dynamic mics rely on having BOTH of their signal leads connected to the 48V, for a net current of zero. But if you ground one side (as for unbalanced connection), the 48V passes right through the coil which is a VERY VERY BAD THING.

I’m waiting for the price of the converter boxes to come down to something “reasonable” (IMHO). It seems really odd to me that they charge as much for a simple converter box as they do for something like the HyperDeck Shuttle, for example. Either one is under-priced or the other is over-priced.
Perhaps one of BMD’s competitors will lead the way with more a more current pricing structure based on the economy of scale now that we are fully into the digital era.

Yes, dealing with 2-pin vs. 3-pin connections is an issue in some cases. Please remember that 3-pin does not imply “stereo”. I believe it is misleading to refer to adapters and cables as “mono” or “stereo”.
In this specific case, the (still unidentified) receiver (presumably the power amplifier in this “system”) has only a 1/4 inch input and it seems quite safe to assume it is probably NOT a proper balanced (3-pin) input.
There are very few proper 3-terminal MIC inputs that use 1/4 inch connectors. For example the Tascam DR-680 which uses them for the 5th and 6th inputs for space reasons.
Likewise, the use of a single connector for stereo is typically the domain of headphones, earbuds, and low-end microphones with 3.5mm mini phone plugs (consumer camcorders, DSLRs, voice recorders, etc.)

“It’s if you have to deal with stereo to mono mixing that you can run into issues.”
Mot really. A mic connection is a mic connection. Mono vs. stereo is a matter of HOW MANY connections, not the fundamental issues of connectivity.

To directly answer your question, yes you can use your 1/8 inch extension cable with the appropriate adapters on each end. As others have observed, this microphone requires NO phantom power, so that is not even an issue here.
HOWEVER, this kind of kludge is just ASKING for trouble and is NOT recommended if you want any kind of reliability.
