help....have camcorder mic audio qusetions Can't Post

ok, i finally decided to get a sony vx-2000 dv camera for taping our high school sports for replay on the local cable network!

now i need help connecting this camera to our three announcer mics!
the vx-2000 was purchased used on ebay and i have not received the camera yet, so i haven't had a chance to connect the mics to it, but thought you guys prolly already know the best way to do it!


we have 3 regular cheap radio shack #33-3024 mics with 1/4" mono phono plugs on them, these need to be connected to the sony vx-2000. we also have a Samson mixpad4 which is a 3 line mic input mixer as well as a cheap 4-line radio shack mic mixer, but im guessing they will not produce enough gain for the sound to come though on the camera?? that was the problem with using the mixers before, when we used them with a consumer sony camcorder, with the mics hooked up to the mixer and the mixer output plugged into the 1/8 stereo mic in on the camera, the sound was very low with the gain all the way up on the mixer?? will this vx camera be the same, or will the line inputs on it make any difference? do i need to get a preamp for the three mics, if so what model would anyone suggest??

do i need a XLR adapter? our mics do not use the xlr connectors, but i could get adapters? would a XLR adapter connected between the mic mixer and the camera work??

currently with the old consumer camcorder i just spliced the three mic's cords together and feed them into the camcorder via the 1/8" plug, and it works very well, but i would rather be able to use the mic mixer!

we just want as simple as a system as possible, that produces good mono sound, no stereo needed!!

thanks in advance, this board is great, i wish i would of found it two years ago!

A mic mixer would have a pre-amp that should bring the microphone inputs up to a line level for connection to a line input. It would be great if you were using balanced mics, but if you've gotten along without them for this long, obviously noise isn't a problem for you.

There are several ways you can go about hooking up your microphones, but the one I'd recommend is that you buy a microphone mixer that will provide the preamplification, and output to stereo, with pan controls for the separate mic inputs. That way, you can not only control the volume from each mic, but you can control it's stereo position (left channel, right channel, or somewhere in the middle).

As long as the camcorder has a line in, and your mixer has a line out, you should get minimal noise pickup between the mixer and the camcorder, because the signal between them will be amplified well above the noise level (except in very noisy conditions). I don't, however, know if the VX-2000 will record from it's line in when in camcorder mode. My camcorder uses the XLR inputs exclusively when in camcorder mode (vs. VTR mode), but the XLR inputs can be switched to line levels; you just need to have adaptors.

p.s. If you could tie your microphone cables together and get a decent level by plugging them straight into the camera, then your mic mixer was not doing any amplification; or maybe the camcorder was auto-sensing the input level and treating it as a line input, even though the level wasn't quite up to line levels.
