Why is humming coming from speaker when mic is keyed?


this is strange as most times if a proper transmit key is depressed , then the radio switches from receive to transmit , the mfg know this would cause some great squeal from receiver /transmitting so close to a receiver so the part that is the receiver is muted to keep this from happening , id say there is some fault in the part that does this muting of receiver

I have 2AKG UHFHT40ULTRA HIGH FREQUENCY handheld transmitter microphone , why when I turn them on they blink on and then notning ?


Okay, before going any further, let's just check....

  1. Along with your wireless mics, you have an AKG wireless receivers (e.g. WMS40 mini2), right?
  2. You've checked that mics and the receiver all work on the same frequency?
  3. You have connected both outputs from the WMS40 mini2 to individual mic channels on a mixing console?

Let's recap....

  • The AKG mics aren't going to work unless you have one of the matching receivers

  • The receiver has to be the correct type. This means if you want to run two mics at the same time, then you need a dual channel receiver (WMS40 mini2) otherwise they'll block each other. So, if you only have a single channel receiver (WMS40 mini) then you can only run one mic at a time, not two.

  • The mics and receiver have to be on the same frequency. They make it easy by colour coding the hand mics and the receiver. If the colours are different then they're working on different frequencies that are not compatible.


If you're good to go on all the above then the next stage is just the connection and set-up of the mics, receiver and mixer.

Since the mics are a pretty straightforward On/Off switch affair then there's not much to say there. Just make sure you maintain the correct distance for to ensure the wireless signal spreads out properly. It needs a minimum of 3m (about 10ft) distance between the mic and the receiver.

The receiver is straightforward too. It needs power, so make sure you plug in the mains adapter. The front LEDs give you the status of the signal. There's only two lights per channel, so it's easy to understand. RF OK confirms that the receiver is picking up the mic signal, so this one should be lit. AF CLIP let's you know when there's too much level from the singer/speaker. This could be that the receiver's volume control is set too high, or the singer/speaker is holding the mic too close for the volume they're producing.

The receiver's volume control needs to be adjusted fully counter clock-wise if connecting to a mixer by a balanced audio connection. If you're running in to the line level input, then the dial needs to be turned fully clock-wise.

The signal connection going to the desk should really be made with balanced leads. Jack to jack (TRS) or jack to 3 pin XLR will both maintain the noise suppression benefits of the balanced audio connection.

The rest is how you set up the mixer for the signal. Good luck.

I have the AKG wms 40 dual mini mic set with two wireless mics. When mic on ch 2 is in the off position, I get lots of static. Works perfectly fine when on. What do you think is the issue?


Channel 2 mic's receiver needs the Squelch adjusted. The squelch control mutes the receiver so that when the transmitter stops transmitting, erroneous noises are not picked up and amplified.

I`ve just bought a new Fender Telecaster Deluxe. When I plug it into my amp there`s a slight hissing hum. When I touch the strings it stops. I`ve tried it through a different amp & changed leads so


you may have a ground loop problem and when you touch the strings you complete the ground loop so the noise dissapears. make sure the amp is plugged into a proper grounded outlet. also there is an aftermarket ground plate that goes under the pick guard. that is what I put on mine to cut the emf way down. if you bought the guitar from a dealer take it back to the store and ask them why you are getting so much noise.

Model: PGX2L5644-662MHz. Its causing a loud sound as if its lost or is loosing frequency even if I am standing with the mic close to the reciever. The ready light comes on and also the signal light when I...


Reset the channel/group on both the mike and the reciever. Shure reuses frequencies by groups so if the group is different, but the channel is the same then you aren't on the same actual frequency.

There should be an auto-set option on the recievers display as well as the mike. Turn them both on, and then just hold the mike up to the reciever so that the little IR window can see the reciever and the 2 with sync together.

If they are both on the same group and channel then turn the mike off, and adjust the squelch control until static is heard, then turn it back until it just goes away.

We have a Sennheiser Diversity Receiver ew 100 and when the wireless mic is off the noise line is on the AF and makes alot of staic until you turn the mic on then it stops. How do I fix this?


Hello! Turn the unit on and push set on the receiver then push arrows until tune comes up, raise or lower frequency of the channel until the noise does not appear in the meter, push set to store settings then push power button to return to normal. Then take the mic and turn it on, push set then push arrow until tune comes up then push set and then set the channel the same way you set the receiver. P.S.. The receiver is locking on to a rouge frequency that is what causes the noise. Went you turn the mic on the receiver locks on to the mic and the noise stops.
Hope this helps you to fix the problem.

Mic hum


Yes, the wiring is different. Reverse the wires on pins 1 & 2, then reverse the wires on pins 3 & 4.

The wiring for you radio's mike is:

1- Audio
2-Ground (Shield)
3-Receive
4-Transmit

Depending on the vintage of your mike, the colors Uniden uses for these functions are white or yellow for audio, red is transmit & black is receive.

My onkyo tx-sr705 produces a humming noise out off all the speakers when no audio is played


I found the source of my hum. I have Direct TV HD. I found that going into the menu settings (Direct tv HD Receiver) /Audio/Sound Effects and turning that option off, I was able to rid myself of the annoying hum. The option has something to do with keeping the audio settings from channel to channel, while it is changing you hear dead air except for the hum. Nice and quit now. Love this receiver!
