Wireless IEM with wireless insturment or mic
« on: May 19, 2017, 11:39:47 am »

I saw this today and wanted to know what the community think and if some one has tried them.   

http://www.widigitalsystems.com/index.php?route=product/product&path=110_133&product_id=88

Yes it is 2.4 and  199 price.   100 ft operating range but that depends on location and conflicts.   


Was looking to use with Behringer x32 rack and ipad to allow for the IEM and talkback.

Wireless digital IEM is always about LATENCY.  And i see no specification on this as to what kind of latency it has.  IEM users can be thrown off by extremely low amounts of latency, especially singers.  Some performers can't even deal with the signal path going through a digital mixer.

I also hate using 2.4G gear as it always works great at sound check when the room is empty and then fails during the show when the room is full.  But your mileage may vary.

If you're going to go digital wireless, get something from the Line6 Relay or XDv series.  There's a reason those units are $200 IMHO.  Not to mention the pure overload of 2.4GHz networks everywhere you go will surely mess with it majorly.

Line6 gear is in the 2.4 GHz range also.

I've yet to do a job with Line6 2.4 and not have it snap crackle and pop!

Wireless digital IEM is always about LATENCY. 

It would be good to find out the latency, I agree. However what is the wireless for, a guitar player or a singer?  Often instrument players want 5-10 ms of delay in their mixes to simulate the normal distance from their amps.

Latency up to 5ms (and for most as much as 30ms) is certainly acceptable to singers, especially if they don't know its there!  If they know that there is, "LATENCY" they might complain since it has gotten a bad rap.

for more Latency info:  https://music.stackexchange.com/questions/30323/when-does-audio-latency-matter-and-not-matter

On the other hand I NEVER recommend anything in 2.4... its too susceptible to audience cellphones pinging away to find wifi.

The newest crop of IEMs from Lectrosonics are amazing.  Connected via Dante the latency is 1ms.  Analog only 1.5.  Connecting digitally eliminates any output latency of the console as well.  Use a mic which is also Dante and total latency is probably way below 5 ms.

I've never had such issues and I've used it with up to 12 channels.

If you consider that the singer will hear their own voice through bone conductivity and the occlusion effect, combined with the delayed signal from the IEM, they could very well hear some kind of comb filtering effect at certain delay times.
Sub 30 ms? I can't say but I would not rule it out.
Instruments, not so much.

There are many reasons that consumer grade stuff is a heck of a lot cheaper than pro grade.  Sometimes consumer grade stuff can get the job done, but eventually, the shortcomings become apparent.

For using as a talkback and mix monitor for an iPad mixed scenario, it's probably going to do fine.  When it decides to fail, that's not a showstopper moment.

I did try once using 2.4ghz headphones when mixing on an iPad.  Worked great during setup.  Worked great during practice.  Didn't work at all once the room was full.  Worked fine again once everyone left. :/

This is the issue.  And it is noticeable at remarkably low latency.

When i was singing with IEMs every week i found i had an easier time actually ADDING some latency to my vocal mic [i added it at the channel strip] to get the weird comb filtering into a less troublesome frequency range.  That and a bit more vocal level did the trick.
