Utilizing two microphones

I have two AKG microphones in the same building that are on the same frequency and interfere with each other. Is there a way to change the frequency of one of them?

I run the WMS 450 systems- basically the same as the 400. These units are frequency selectable. change the frequency on the reciever, then transmit the new frequency to the mic via the infer-red sensors:

Unlock the reciever by holding down the middle button until lock dissapears (if Lock is on screen)
Navigate the menu to the frequency selection page (looks like [AU B1 C1] "i think")
AU is a country selection, "not really important" e.g. AU = Australia
B1 is a bank number
C1 is the channel number in the bank
Just change the bank or channel number (these represent preset frequencies)
when you select the new frequency "PROG IR?" appears
Get your beltpack or HH set to prog/mute
line up the infer-red sensors
Start PROG IR on the reciever
The reciever should then send the new frequency information to the mic
"IR OK" should appear if succesfull
It does not work everytime so turn the mic off and on and transmit again.

I hope this will help,

No, when you buy multiple wireless mics you have to select different channels per unit if you want to use them on the same stage.

hope this helps
thanks for your rating

How to change frequency interference range on AKG rs 40 wireless microphone?

Go on line and search for operators manual. You may have an older unit with frequencies that were given away from the AV world to the internet world and this may ultimately be the cause of interference.

Do a search of legal frequencies for microphones

Unit is an AKG SR40 Dual Pro Wireless receiver, PT 40 transmitter. 662.3Mhz operating frequency. The right side channel is hypersensitive and indicates that it is picking up a signal when the transmitter...

I would suggest that you change your operating frequency. The antenna being removed suggests that the receiver is picking up interference on that frequency. This frequency is in the UHF TV band, and although analog TV no longer exists, digital TV still uses some of the frequencies.

I have a SR 40 Single WMS 40 Pro and the "bug" that fits into the 1/4 end in my guitar has taken some wear so even tho it's hinged it has loosened up both directions and ocassionally has to be wiggled...

AKG may have replacement parts, but they only keep them around for 7 years, so depending on age/mfr. date....That unit is also out of date with regard to the frequencies used on it. It is actually ******* to use that unit in the USA today, as the feds at the FCC sold off those frequencies to the cell/telco companies a while back.

Problems with my MXL 990 (radio)

g'day mate.
The problem you have will relate to the big antennas in your area. Most radio stations pump more than 100,000 watts these days. So it really comes down to the shielding and what's called Radio Frequency Interference rejection of your microphones to keep this out. I would STRONGLY urge you to take the mics back and get a refund,or change them over for something else. They are VERY cheap, there is no real solution to your problem, except for better design... means spend more mullah. If you are looking for a decent low cost condenser mic, I recommend an AKG Perception. I have used AKG for years, and this mic is a great sounding low cost unit.

Hope this helps you. Nothing can be done to improve what you have, they are a cheapo item. Good Luck
