Make sure the internal gain/volume controls on the Lav transmitters are set accordingly.

While gain-staging is important for wireless microphones (particularly for analogue ones) to ensure low noise, it shouldn't materially impact gain-before-feedback (after all, "gain is gain" regardless of where it's being added).

Has anyone else had trouble with their M20 threaded Pole Cups?

The end result is basically a Global Truss SQ-4137SAP with an M20 hole through the middle, except that the 'Speaker Pole' stud is welded instead of bolted on to allow for the coaxial hole.

I put a pair of these adaptors on each end of a stick of truss. I use 1.25m segments, naturally you can pick whatever length suits your need. Each end bolts securely into its respective speaker. The 12" footprint is far more stable than a single pole. Plus they look pretty cool 😎.

I did this with F14 truss, which still has a very small visual footprint, but much more stable than a pole. This is an RCF NX-L24a on top of a JBL SRX818.

Very cool, but seems a bit overkill? 

We ended up putting M20 pole sockets in the tops of our small Meyer subs, and bought some of the K&M speaker poles that have M20 on the bottom and 1-3/8" on top.

Oh, its definitely overkill.   

However, after having an M20 pole cup fail at a gig, I don't trust the straight poles anymore.  The weight of an X40 on top of a straight pole was able to apply enough torque to break a pole cup. Can you imagine with a UPQ?  These truss assemblies feel solid with a UPQ on top of a 900LFC.

Maybe I’m missing something, but why not just put an M20 bolt through the middle of the plate straight into the cup?

... my guess is unrealistic expectations.

Agreed.  Yesterday at church the person speaking insisted on wearing a lav instead of an earset mic, and standing on the extreme downstage lip of the stage - right under the center speaker.  Even after pulling out the 3 worst offenders via channel strip PEQ, there were still 3 offending frequencies.  Countryman lav. 

Lav mics are great - for broadcast or other applications where there isn't a live PA in the same space.

Has anyone else had trouble with their M20 threaded Pole Cups?

I use Meyer X40 and 900-LFC with a single threaded pole, and found that setup was a bit wobbly, and that wobble led to one pole cup failing. A colleague had the same issue. So, I came up with a more robust solution and had these Truss Adaptors built. 

I'm posting to see if there's enough interest in the community to build a small batch to share. 
Mods, please move to a more appropriate forum if necessary....

These adaptors work with 35mm (1-3/8") pole cups that have an integrated M20 threaded socket, such as Penn-Elcom M1557/M20
https://www.penn-elcom.com/us/universal-speaker-mounting-top-hat-m1557-m20

These pole cups are standard on some Meyer Speakers, but I'm guessing are common with others, and are likely an easy retrofit for others still.

These adaptors use an off-the-shelf Global Truss F34 12" square base plate, with a 35-mm aluminum tube welded on. An M20 bolt fits through the tube to secure the speaker to the plate.

The end result is basically a Global Truss SQ-4137SAP with an M20 hole through the middle, except that the 'Speaker Pole' stud is welded instead of bolted on to allow for the coaxial hole.

My cost for the first round was about $400 / pair in a batch of 8x. That includes a pair of plates, pair of bolts and washers. If there's enough interest and we can run a larger batch, we can hopefully get the cost down a bit. If you're interested in getting a set, please DM me (info <AT> sierraaudiosolutions <DOT> com) and we can talk!

Thanks!

{...} Last night was our first gig with the X32R, which is brand new and running the current firmware. {...}

{...}I've verified that all of the major settings are the same between the MR18 and the X32R. I'm not really sure how to even begin to diagnose whats happening here. {...}

Can you post a copy of your X32 show file for us to look at? Easiest way to do this is probably using a USB stick in the console (you can also use the X32-Edit software on a computer), then change the extension in the file name to "txt" and attach it to a post here (the forum restricts what file-types can be uploaded, but since show files are just text files with a special extension anyway it's more than happy to accept a show file if the extension has been changed).
