Headset (or earset) mics with cardioid capsules would be the best for avoiding feedback. Omni capsules usually sound better and can be used in many live sound system environments as well. H/H mics work, but I would avoid them with inexperienced presenters. I did a lot of live panel discussions and always liked to use a mixer's pre-fader aux sends to feed the house system and the main faders for the on-the-fly recording mix.

Yes, they tear up the battery covers over time. I have had some of the holder's retention tabs break off as well, so those batteries can easily fall out.

Sennheiser made a NB-2 "Headset Adapter" to use with y'own lav mic. I do not know if it is still available.

+1, Redundancy.

For high SPL sources, I use a Sennheiser 421, I also have a Shure Beta 91a, but I have never used it on anything other than a kick. The Phantom Powered Beta 91 is a half-cardioid boundary mic. SM57s can handle high SPLs as well. I have a few of them for snare and guitar amps and as a podium/lectern mic. I am sure the DPA 4055 sounds good, It's a little pricey for occasional use and I already have the above.

Generally, bias current supplied by an XLR Phantom Power adapter/converter/or battery in very low, so a AA cell should last a long, long time. current draw is usually disconnected when it is unplugged. I have TA5 (Lectro) inline XLR power/converter/adapter with a LR44 button cell that lasted for years.. and then some.

btw, I also use AATranslater for an occasion conversion which usually works relatively good.

+11 AAF has always been problematic for me going x-app and platform. OMF worked 90% of the time. The other 10% was pilot error (export) by the video post editor. Unfortunately most NLEs dropped the OMF export option, and convertions to OMF or other compatible format is hit and miss.

Correct. Tip= Mic, Ring= Line (though a true +4dB nominal feed is a little to hot for the 100 series SK Tx and will need some external attenuation.

I had a set of 600 ohm AKG K240 headphones. The HP volume was adequate on my 302 but not on many other devices. I do not know about the Nova or the HP amp specs.

I built a small simple XLR cable tester about 20 or more years ago with spare parts and a few low cost items from a brick & mortar) Radio Shack (RIP) . If the cable is good , the LED illuminates, if not, it is taken out of service for future repair. It can also test other balanced audio cables with pertinent adapters. It a has a switching transistor, a diode, one or two resistors, a LED and a 9V battery. It is about 2.5 x 2 inches.

A good start point would be looking at the local broadcast frequencies in your area and the Sennheiser blocks. https://wff.sennheiser.com/ Then go from there with recommendations from other users in the area. Checking the area with a RF Explorer at different times is a good idea as well.

The (made in NJ) OST (Oscar SoundTech) 801/802 lavs are almost identical to the Tram TR50 for $110 (usd). A choice of (soldered on plugs) is another $20-30 as I recall. The flatter response (4mm) TL-40 is the same $. The OST mics I have, had held up as good as most others (all kinds of abuse and weather).

They are mostly an ornamental prop, but word has it most are actually plugged in if needed for some reason. I am not sure if Larry King's iconic RCA 77DX was connected though.
