Wireless hearing impaired receiver

Postby ursenj » Thu Dec 23, 2010 12:23 pm

Has any used the wireless hearing impaired receiver to feed chapel audio into their mixer for broadcast audio? I have never listened to one and I bet they may not have the best sound but with two other condenser mics (maybe a pair of C2 Behringer, or a single B-5?) into the mixer for the choir it might do OK. Looking for your thoughts on this. My issue is getting all of my gear with video feed and mics and mixer in one location.

There are pros and cons. One nice advantage of the receiver is that I think the audio is compressed before transmitting. But one downside you may run into is the reliability. I've seen transmitters go down for months or become flaky before they get fixed. Unless you have a feel for the reliability of your particular unit, you probably should have a backup plan.

Of course, if you're already running mic lines to the choir loft, it doesn't seem that much extra effort to add a connection to the sound system.

All in all, given the mission critical status of the broadcast, I see more risk than benefit.

Yea I still do not have a clear plan as to were I am going to set up shop. This is my first one and just exploring all my options with out make the stake center look like a black gaffer tape mess. I think my last Stake Specialist did it upstairs in the utility space were he could interface with all the after thought cabling needed to make this all work in the past. I am just exploring my options at this point.

We do have several new receivers still in the package. Plus I could have a spare read to go with some Lithium batteries.

Thanks for the input.

The reliability issues I'm concerned about isn't the receiver, it's the transmitter. We had an older model that proved to be flaky.

I use the building’s hearing impaired Comtek PR-72b to record sacrament meeting talks for the home-bound members. It does a great job and have never had a failure (about a dozen recordings). I’m sure you could use it in a pinch but I agree with RussellHltn and would not rely on it for something as important as a stake conference broadcast. I would always use a direct feed.

I am not sure where you set up but there is usually a line out somewhere in the chapel or in the satellite and building distribution rack. Those would provide the most reliability.

[font=Calibri][size=100]What about a remote controlled audio mixer?

Mixing the choir/piano/organ is a different issue but I got an idea from another post about controlling an audio mixer via remote and started researching to control an audio mixer via Wifi. Since I operate the video and audio for Stake Conference broadcasts in the materials center, I wanted to be able to mix the choir/piano/organ audio before it was fed to the other buildings. With one line already run from the choir loft to the materials center (22/2 shielded), mixing of the choir is accomplished by using an audio mixer set up under the piano and controlling it via Wifi and PC software from the materials center. [/font][/SIZE]

The audio mixer is an EAW DX8 (Mackie) and serial communication is accomplished via a Lantronix W8X2100E 802.11b/g serial bridge. The mixer has 8-in and 2-out along with some awesome EQ, compressor, auto-mix, etc. features. The mixer's serial communications port is connected to the Lantronix serial bridge and the audio output of the mixer is connected to the line that goes back to the library and out to the other buildings. Audio is mixed using the DX8-PC software running on a laptop.

For reliability, I use the pulpit audio feed that comes directly from audio distribution amplifier located behind the satellite equipment.

The total investment was $250 (eBay), but it took a couple of months to find the bargains. :p
