Line to Mic level
      #1018754 - 15/11/12 08:16 PM
Hello,

Is there an easy way to pad a balanced +4 line level signal (out of a mixer) down to an unbalanced microphone input (1/8" TRS) on a camcorder?

What I'm trying to do is take the audio out of my mixer and put it on the video to save time synching it up after the fact.

Thanks,

Peter

I'm not saying it's the best way to do it, but I have achieved a similar thing by feeding a line level signal into the input of a DI box, engaging the pad on the DI and taking the attenuated signal from the output.

I use them all the time. I had a tech make up a couple of cables similar to these designs http://www.uneeda-audio.com/pads/

I use them to feed line level signals to coloured preamps for mixing.

TRS implies it may be a stereo signal. Do you know if this is the case?

Depending on the model of your camcorder there may be a gain level on the mic input which opens up a few more possibilities. Might be worth investigating.

Great link that, Jack.

The official device was known in the video production industry as "beach box" although this is
a nickname.

I now know why, as this company makes such devices:

http://www.beachtek.com/

1/8 inch does often imply stereo on a semi pro camera, a DI (or 2) would be a hassley and slightly impractical but working lash job if you can get the adapters you need. When I started work experience at a Radio and TV production company within 2 weeks I had to oversee the kitting out of a video black/chroma key room with a very let say "firey" producer. My manager at the time dropped me right in the deep end, lol.

Thanks for the link to the beach box, that might be just the tool for the job.

By the way, you are correct, the 1/8" TRS is for a stereo microphone. I read somewhere that the 1/8" TRS mic jacks put out 5 volts of "plug in power" sort of like the poor cousin to phantom power.
