I have 3 sennheiser ew100 G2 handheld mics which don't work properly ( rattling sound ect;)i would like to send them off to you to get a quote on how much to repair them how do i go about this.

Hi Edgar, it is important that the receiver works, because there is a dialogue between the transmitter and the receiver to confirm that they are on the same frequency, that is why the transmitter is blinking, you should repair the receiver and look for the frequency or channel that the transmitter is found and it will stop flashing

Hola Edgar, es importante que el receptor funcione, porque hay un dialogo entre el transmisor y el receptor para confirmar que est?n en la misma frecuencia, por eso es que el transmisor esta titilando, deber?as reparar el receptor y as? buscar la frecuencia o canal que se encuentra el transmisor y este dejara de titilar

This will never work together. They are on different frequencies

We'd need to know more about the receiver than the mic, since it's the receiver that is muted. Muted means NO SOUND.

Hi,

Maybe the gain in the receiver is down.
You can adjust the outputgain the menu.

Good luck,

Add a DI box to clean up/boost the signal of that mic. If all the channels are doing this, get a bigger (more watts) amp so that you have more headroom.

You should'nt need a scematic, this happens all the time with the ew100 handhelds. you will need to remove the three star bit screws between the screen and the batteries, pull off the end cover and with a small screwdriver or some long needle nose pliers- put the red button back into the hole from the inside of the cover. Just take care when putting the end cover back on- sometimes its a bit difficult.
Goodluck

Rechargables aren't recommended for wireless operation because they can die suddenly without warning. Plus the older they get the shorter their life span. Go back to good quality batteries and you should be fine.

This is a well known problem with the EW100 series that is easily solved.
You will need to run this reciever into a line input via a mono(TS) jack to jack lead. this will bypass the phantom power.
Make sure that you set the AV OUT to +18 in the reciever menu to get optimum level.
Phantom power is only present in the microphone inputs XLR3.
Hope this helps.
