Buzzing noize I have a R200 UHF wireless microphone system used for my violin, the problem that i am getting is that when i connect the wireless sysytem to a main p.a. system i am getting a laoud buzzing noize coming through the speakers to the point were i am unable to use it whilst performing on stage. What can i do to avoid this problem?

First, replace the battery. If that does not resolve the problem, call Shure Repairs at 800-516-2525.

I assume you are wanting to connect the output of the receiver into the input of your guitar amp. Use the 1/4" output on the receiver to the 1/4" input on your guitar amp.

Yes I have this exact problem myself. Work for nightclub and our original Shure wireless was fine and we replaced it with an slx. We have MCs that really yell into the mic. I'm gonna try and find an older 58 capsule to pit on it and see how that goes. The mic would probally be fine with normal singers.

You need power from the transmitter to power this mic. See your mics specs to determine if it needs "Phantom Power"
Perhaps the transmitter doesn't supply power. Condenser mics may not work. Stay with the dynamic type. IMHO

Unfortunately, you don't have enough information to go on to give you a definative answer.

The Sampson Aireline will plug onto ANY xlr type DYNAMIC mic and should work.

The one thing on the AMT Elite I found said it was a "condenser" type element which means it would NOT work with your Sampson setup. Condenser mics require a Phantom power arrangement to charge the element and operate the local FET input amplifier.

If you are trying to mic a violin, the Airline 77 that was for the dynamic mics is a very poor choice as it is low impedance. Most violin pickups use a Piezo pickup which requires VERY high impedance input amplifier.

For my wife's violin we use an Autolycus pickup and an X2 wireless sytem. The pickup comes from New Zeeland and the X2 is CD quality digital wireless link. You have to make your own connector at the violin for the X2 cable was intended for guitars.

Yes, and it will pickup "handling noise" as well.

A hint I can offer is to try a mute. One of the bent wire ones with weights that clips over the strings in back of the bridge..

I have found a perfect match for my wife's violin. We use an Autolycus pickup and an X2 wireless link. NOTE: the piezo pickups require a VERY high impedance input amplifier. You MUST use a very short cord or all the highs get wiped out.

We got the Autolycus from the source in New Zeeland (about $70). The fellow has a website with a sound clip. Search Google for Autolycus violin and you should find it. Do listen to the sound clip. The little piezo clips on the top where the sound post is with a plastic clip that reaches through the treble side F hole.

I had to make my own cable for the X2 wireless as it has a TRS 1/8 connector and the signal is on the ring and the tip and sleeve are ground. The Autolycus comes with an RCA jack on a pigtail. The X2 has a very high impedance input at the transmitter which is ideal for the Autolycus pickup. We use a Berhinger ACX1000 acoustic amp. It actually sounds like a violin.

Use good quality strings is important. The X2 system is a digital transmission at near CD quality.

I have found a good combination for my wife's violin. We are using an Autolycus pickup (from New Zeeland about $70... search Google) and the X2 wireless transmitter/receiver pair. The X2 has the extremely high impedance required by the piezo pickups. This pickup clips onto the top surface of the violin with a small plastic clip through the F hole on the treble side. It is easily moved between instruments.

The Autolycus is sold online and they have a demo there.

Of all the pickups we tried, this one "sounds like a violin" and many people have complemented us on the way the violin sounds. A sound man said of the setup, this is the first violin pickup and wireless he has not had to EQ to sound right.

I used an oscilloscope to verify the output waveform from the pickup matched the resulting output of the X2 receiver.

Note: I had to make my own cable for the pickup which has an RCA female and the original X2 cable supplied had a 1/4 inch male.

I got the X2 system through online ordering from MF. (They recentely had a special on them at $220. The wireless is really nice... no long cable to load down the piezo.

You need a separate receiver for each microphone.

Make sure the microphone and the receiver are still broadcasting/receiving on the same channel.
Check that all of the appropriate connections are right from the receiver to the mixing board are connected as well.
I hope this helps!
God Bless you!
