Wireless line level
« on: October 08, 2015, 09:56:29 am »

I'm sure this has been discussed a zillion times, but my search skills are failing me.

I'm looking at ways to wirelessly transmit a balanced, line level audio source from a mobile cart into a fixed installation. Must be cheaper than Shure P9T-to-UR4+. I'm not a fan of Bluetooth for this purpose. The application is a High School gym.

I'd appreciate either suggestions or a link to previous threads. Thanks

The PSM->UHF-R setup is pretty bulletproof; you can also look into Lectrosonics and Sennheiser versions.

For near-zero latency, nothing beats analog transmission.

On a tight budget, microh makes a decent system. For about $400 you can get the transmitter and receiver

It's actually not too terrible. Used them a bunch for speaker on stick delays/vip areas, etc.

You can use about any wireless beltpack and receiver to point to point transmission. You just have to make sure not to overdrive the transmitter so you'll likely need an external pad in the line.

As someone posted there is virtually no latency if you go analog. However you'll likely benefit from latency and the addition of even more. Digital will certainly sound better and will not shift frequency response as the input level shifts. Also most digital schemes do not add a compander so you can avoid that whole nightmare.

Don has good points (duh, of course he would). Lack of companding/artifacts and full bandwidth audio are really nice things to have for full-range playback.

A typical HS Gym = Acoustic Toilet.

It may sound like heresy, but a little bit 'o latency can be be your friend with open-mic sources.

I use a Shure ULX belt pack with the battery eliminator mounted on a mic stand. If the receiver is not too far, I just use the supplied antenna (I sometime gaff tape it to the top of a speaker) and if further away, a paddle.

It can work well to simply get through a wall with no available openings.

I did a fair with several satellites. 
I used a Sennheiser 300 in-ear transmitter to a Sennheiser mic receiver at each satelite.
Worked great.
