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.
