Hi.. please help. My Sennheiser Shotgun Microphone ME 80 suddenly started to make an high hiss noise.. the mic has died ?

Hi, you didn't say if the mic actually passes sound? The C-1 is a condenser Mic & needs phantom power - switch on the rear of your mixer. If that's no help, what happens if you disconnect the mic, then turn the levels back up? Still hissing or gone? If it's gone then it's the Mic - must use a 3 wire cable, preferably XLR so it gets the phantom power. If the hiss is still there without the Mic then sounds like the mixer is faulty - try some of the other channels..... How loau is the hiss - just in the background or as load as a vocal "one, two" test? A few things to check anyway...... Good Luck!

Try a different mic to see if problem follows. If yes then it is a setting. If not then the mic is bad and needs to be sent to mfg or get a new one.

Look to see if there is a capacitor across the switch terminals. If there is , replace it.

This would require a special cable to work. The mic is MONOAURAL with BALANCED output and the camera is STEREO input. This means a special cable is needed and you would probably have to make it yourself as I haven't seen one on the market.Pin 2 of the XLR of the mic would go to BOTH the tip and ring of the plug into the camera. Both pins 1 and 3 of the XLR at the mic would tie to the sleeve of the plug to the camera. If you tried an XLR to 1/8 adapter, no audio would be heard other than from the buillt in mic.

The hiss is caused by your monitor system level and your preamp gain being so high. At high gain settings, a preamp is going to get noisy, and tube mics have a higher noise level to begin with.

If you can't hear it on your recordings, then it's not a problem.

Hi, You can check you the connectios or the mic. remember that the mic is too sensitive, you can adjust it with the nobb on the mic by putting it on o -dB and reduce the highs on your mixer or EQ to reduce hiss sound.

But fisr check the connection properly to see if when muted, is muted properly.

Take care.

That's probably not going to work.
Mic level is extremely low compared with line level.
Your sound card is expecting a line level input.
It's simply not made to plug a microphone into (you must be using an adapter or two just to make the connection)
Look for a USB Audio Interface with XLR or 1/4" microphone inputs - these interfaces are pretty generic these days and easy to use ... just plug into your computer via USB and then plug the mic into the interface ... which has a volume control on it ...
I use a Tapco Link.USB ... and like it

This is probably interference in the wireless connection for the lavalier mic.
Try switching channels to find a clear one!
Or switch to a wired lav mic if that's practical.

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.

my mic was plugged in the front panel of my pc. it was producing that hissing noise. then i plugged directly into the sound card at the back of the pc. problem solved.
