Audio-Technica freeway 200 Series VHF Wireless System - I had problems connecting the wireless system with a quarter inch to a xlr. The sound system made a very loud disturbance sound. What cable do I use to connect??? [email protected]

That's called, "interference". Somebody else is broadcasting on the same frequency, perhaps a local fire station or other radio transmitter.

Here's the owner's manual for that series. You'll find the battery replacement instructions on page 6: http://eu.audio-technica.com/en/resources/2000a%20Series%20Owners%20Manual.pdf

Try calling Audio Technica. They can probably assist you in troubleshooting and/or getting it repaired correctly.

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

No, the ATW-R200 series are fixed-frequency units.
Short of soldering new crystals in, you're stuck with the frequency you've got.

Audio Technica is generally a good brand name in microphones, but sometimes if you talk to musicians they tend to favor names they are familiar with like Sure. In the church, school, venue world, audio technica is respected. I work audio in three separate venues and we have no trouble with our audio technica microphones.

Have you adjusted the channels--and have you tried to do so manually? Have plugged the working one into the same inputs the nonworking ones were plugged into? I know it sounds like a simple thing to ask, but sometimes the connections to the sound board are the issue. If you have the more advanced receiver for the freeway 700, there are other adjustments designed to allow you to adjust between guitar and voice. If it is preset to guitar it will not sound good for voice. You may have to change that. I am assuming you put in new batteries, but ifyou have not, you may want to try that as wireless mics use up batteries quickly.

Those are a few possibilities. If it is the actual unit, then you can look inside and see if something is loose, but as far as repair, that gets into a whole issue. Hopefully something above helps solve the problem

I hate to be the bearer of bad news but those units are fixed frequencies and cannot be changed. You either have to find a mic that matches your receiver or vice-versa. The freeway 200 series comes in 3 freqs. two of witch you have with the addition of 170.245. Maybe you can find someone who has a damaged mic but still has the receiver with the freq. that you need for your mic.

the unit I'm using is old and is on a 200mhz frequency and it uses Vhf, so I have to buy a new unit.....nothing can be done to fix the problem....

might just be the mic wires came loose...I have oner and the mic is held in by a small rubber O-Ring and as people drop it it falls out and can short out
