I don't know what you've tried already to improve the signal level, so i'll list a few things that migt help.

It might help to put new batteries in (with the right voltage) You probably did that already.

There is a GAIN pot on the mic, in the battery compartment under the ring that is screwed onto the mic. When you adjust the GAIN, there will probably be better SN-ratio, but it does'nt change the RF signal

You could also adjust the antennas of the receiver, or try to set a different frequency (depends on which country you live in, in some countries it is illegal to change frequencies) or turn off the SQUELCH on the receiver

If this does'nt help, you could look for a user manual and try to find a solution in it.

There are some other solutions to improve RF signal, but those are quite expensive.

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.

Why won't wireless mic turn on the "Ready" light on receiver?


Make certain the mic and the receiver are in the same exact frequency band. There are stickers on both products that list the frequency band.

The handheld is in a different frequency band than the receiver. There are stickers on both that saw what frequency range they can tune to.

My AKG C1000S shows a weak signal from one side of the two stereo channels when I use an XLR going to a 1/4 inch Stereo jack. Does the mic only work properly with a Mono jack?


You have connected the mic improperly. You'll need an XLR to 1/4" transformer to properly match the impedance, then run into a mono channel.

Dont know what size battery to use for a nady ht-3 mic transmitte


Hi, nady ht-3 mic transmitter uses a 9 volt battery ..coolken_15.jpg

To insert the battery, You will need to unscrew the below button part of the hand held mic (anti-clockwise), and after unscrewing, you will see the space to fix in the 9 volt battery..

When you buy the battery,before fixing the battery in, check the polarity before placing the battery in (positive + and negetive -)...After inserting,screw back the cover in and locate where the power switch is..It always has an indicator to know if the power is on...

Note..make sure the Transmitter is on for it to be able to work properly with the hand held microphone....


Good luck..

I need to purchase a lavaliere type mic for my passport 150 and I am not sure what I need, It comes with a hand held ireless mic but I want to use a lapel type.


Wireless systems can be purchased as either lapel or handheld systems. Talk to the dealer that you are purchasing the wireless from and let them know you want a handheld system.

Interference problem on my wireless magic sing, i can hear the voice of my neighbor using her own wireless magic sing on my sound system and vice-versa, it's annoying. what should i do?


The magic sing has an omnidirectional antenna which is unnecessary since you will be standing directly in front of it while using it. I recommend you take an aluminum pie plate or other aluminum piece that is larger than the antenna and place it directly behind it, perhaps even held on by tape to the antenna. You can even bend it around the antenna in the form of a V with the opening towards you, where you'll be holding the mic. This will block the other signals from your neighbor while still allow you to use it. It may even block your signals from leaking onto your neighbor's unit.

C 518 ML Isnt Working


Make sure that you are supplying phantom power. This mic requires it. Without phantom power, the mic will appear to be dead.

Let me know if that resolves the problem.

AKG 414 crackle


Had the same problem. Check the ground (earth) is attached properly to the mic. This will cause the signal to be interrupted and can also cause a phasing problem. A lot of techs don't check that when you send them for repair
