Shure LX1 transmitter at DVinfo.net

Kris Verstappen · December 1st, 2003, 07:22 AM

I'm planning on buying a Canon XM2 in the near future. The information I've gotten from this forum so far has helped me loads in deciding.

I have a question concerning audio however. Between some "old" rubbish I found a Shure LX1-PD wireless transmitter with lavalier microphone. What kind of receivers could I use with this? I would prefer to buy a receiver that I could later on use with another system (like Samson / Sony ECM-77 combo). And of course I should be able to connect the receiver to the XM2.

Cheers !

Does the wireless transmitter have any indication on which
frequencies its transmitting? If so, you should be able to find
some receivers that can listen to that frequency I would say.

Looking at the lack of response to your question I don't think
a lot of people are familiar with that product.

Thank you for your answer Rob. I was getting affraid I asked the impossible :)

The transmitter does indeed have an indication of frequency. Namely: 204.600 Mhz FM

Do you think this could be used with several receivers, or more likely only with a Shure receiver?

My guess is that it would work with any receiver that can pick
up that band. Perhaps you can bring your transmitter with you
to a shop to test it with the product you are interested in?

I actually don't have much experience with such devices myself,
so I'm not sure it will work. But I can't imagine it won't. I hope
some other people will chime in with their experiences.

Although you might find a receiver that can pick up the frequency, you may be dissapointed in the sound quality. Most major wireless microphone manufacturers (Shure, A-T, Sennheiser, etc) optimize a given transmitter to a receiver. To allow a wireless microphone to get the maximum amount of performance across the RF link, the audio is compressed in the transmitter and then expanded out at the receiver. This is known as the compander (COMpress and exPAND) process.

Thus, the expansion needs to be matched to the compression or audible artifacts will be heard in the received audio. That is why a given manufacturers transmitters don't work with anothers receivers.

I hope this lengthy explanation helps.

You need to find the appropriate Shure receiver to go with your transmitter.

Thanks for the info, Steve. That sure does answer my question.
