Question about Audio Players & Recorders
Batteries get hot and drain quickly when the microphone is on. I'm thinking it is a short in the microphone. However the positive and negative leads aren't showing one with a meter.
You won't need a complete short to drain the battery much faster. Unless you can compare the figures to a known working one it's difficult for you to tell what is right and what is wrong.
Is this a handheld or a beltpack? Is it a genuine unit or a Chinese copy?
A set of GOOD batteries (Duracell, etc) should last between 6 and 8 hours minimum with these units.
If you have the tools you could take the unit apart and look for signs of failed components. A partial short circuit on a board due to moisture (from sweat or other liquids) can cause higher battery usage.
At the worst case, Sennheiser fixed price repair is around 60pounds exc vat.

SOURCE: on/off button broken
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.

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.

I had a similar problem with a sure sm 57 that I used on a guitar amp. I don't know if this is the correct fix but it worked for me. I took thin strips of paper to use as spacers and placed them evenly around the coil. I used a hot melt glue gun and placed 3 small drops around the edge of the coil. Remove the spacers and the coil should be secure.

Hi, Sennheiser SHOULD still service these. I'd recommend having another go.
However, i'd like to clarify which part of your system has failed. Is this the locking jack plug on the ME2 / ME4 tie clip mic. A common failure point.
Or the antenna on a beltpack (also common), or something else?
They're both fixable, the locking plugs are available to buy now from other suppliers. And the antenna are just an m3 plug with a solder bucket in the top. A HOT soldering iron, and a bit of heatshrink can repair these.
If you don't have any luck then you can contact me direct and i'd be happy to have a look for you. email@example.com
