If you have low audio, the transformer is cooked. This happens alot if you drop the mic. You can send it to me and have it fixed for $70 plus shipping, or contact your local audio dude. thegraphicguy@live.com

I found this happens with a bad capsule.

On the end of the wire you have the microphone capsule. If I remember correctly, the capsule can be unscrewed from the microphone amplifier case assembly. This part can be ordered from a supplier for Sony professional parts.

I have also had the wire go defective, and need replacement. With most of these models, the complete capsule assembly has to be replaced along with the new wire.

If you are not used to servicing this type of microphone, Sony has service reps that can service and test the microphone for you.

I have a Sennheizer evolution g2 transmitter and reciever to go my Sony EX3 - but the input level is too low - could this have to do with the frequence I'm on?


Hi,

It got nothing to do with the frequenty.
You can adjust the microphone gain in the handheld-menu. You can also adjust the receiver-output gain in his own menu.

Good luck,
Gerard

Low signal


The battery may be getting weak. Also, this is a low impedance microphone. If you have it plugged into a high impedance device the signal will appear weak. If this is the case you might try getting a matching transformer. They are usually available from any decent musical instrument store or electronic supply.

Microphone too quiet


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

Can not set device input level in system preferences for MAC


That's correct. There's no other input volume control besides the analog knobs on the front.

The level's still too low with the knob turned to max? What are you trying to record?

Should the light come on!?


Hi timtak

The light should come on momentarily when you turn the mic on, and then go out. If it remains dimly lit, or does not come on at all, then the battery needs to be replaced. The way the light responds is supposed to indicate the condition of the battery for you, unless it is so depleted that there is not enough juice left to light the LED. You can read up about this in the user manual here if you want:) A FixYa is a great reward for sorting this out for yah. Cheers

Battery change


The battery is housed in the xlr adaptor DC-78. You may need to unscrew the barrell about the outside of it to replace the batt.


Or alternatively use phantom power to run up the mic(this is easiest

. Be sure to connect it to a channel that is phantom power optioned

Here is the spec sheets for it with details of the adaptor you need and battery type required.
