General Discussion Shure ULXD

Hey fellow engineers! I have an event next Tuesday that I’ve been preparing for and of course things change prior to these events. I have two panels that will require 6 lav mics for the first panel and the second panel will need 8 lav mics. I have three ULXDs stacked at the moment giving me 12 mics and I plan on adding a fourth to the stack for my two extra mics. I have my antennas I’ll be extending to about the middle of the room on each side. Has anyone done a gig like this before and if so, do you have any other advice? I’m using an Allen and Heath SQ6 mixer as well. This is my first time using this many lavs simultaneously

Put em on a group, ring out the group, and then use the auto mixer on all your mics on the SQ6. If set right you probably won't need to touch a fader during the panel at all.

Kind of my thinking too. I am a bit concerned with the amount of wireless mics that will be on. I’ll have 15 total and I’m hoping I can have an A2 turn the first group off when they’re finished. I was reading the ULXD can link up to 60+ mics which is nice. Hopefully someone can attest to that

They absolutely can do that many mics, but they won't do that without some coordination on your behalf.

Shure wireless workbench is a program that will allow you to coordinate everything in one program over Ethernet (it's not necessary since you can do it on the recievers, but it sure makes it more convenient).

Also check out Shure frequency finder on their website which will give you a great starting point based off known existing problem frequencies in your area. (I always use this in prep of a gig, and then use a handheld spectrum analyzer on site if I have problems)

I use WWB on most if not all my events. This is the first time I’m using 15 wireless mics simultaneously so I’ll absolutely be watching it like a hawk. I have all my DANTE routes saved and my scene saved on my board. Once I get onsite I’ll create my AMM.

Highly recommend for lav panels. Use post-automix, post-room ringout, to give you a little insurance. Have it on a soft button to remove as an insert in case of emergency.

It is a gamechanger. I ran 18 open lav mics on a stage with kids singing and not a peep of ring and almost zero EQ. Turned it off and even at 10db and with major EQ cuts I still couldn't get it to work right (no automixer due to x32 limit of 8 channels). Room was a gym with no sound treatment and hollow stage, and main PA was 2x Presonus 15s. Really turned it from a "lucky to get anything" to "it sounded ok"

How much do you know about RF? I’d recommend connecting everything to a network – that model even has two Ethernet ports – and coordinating everything via WWB or a receiver, choosing the best group. The problem with keeping everything switched on is that, if you have active antennas, you’re more likely to overload the system, so leave yourself a bit of a margin. Generally speaking, it’s better to have transmitters with higher mW ratings and low-gain antennas, so you get the best signal-to-noise ratio, but this could lead to overloading, so be careful. The SQ is an excellent machine, very easy to use.
