I've had the opportunity to use the azden cam-3 for the first time at a wedding anniversary and I plugged in my three mics to it; on channel 3 I plugged in my stereo shot gun mic and I moved the slider on the Cam-3 all the way up to increase the audio signal and I notice that this mic was my weakest one, so I increase the audio levels on my camcorder accordingly.The wireless and the interview mic had stronger audio signals so I moved the sliders down for channels 1 and 2 to adjust the audio for each one of them accordingly. It gave me the flexibility to open and shut each mic just the way I needed.
br /I was hesitant about buying this audio mixer because of the first bad review that this person gave to the Azden Cam-3, but now that I myself used it I can tell that he just did not know what he was doing, that is why I took the time to post this review. Great product at a great price. Keep up the good work Azden.

It does just what I need it to do which is balance two microphones. It does not amplify the weaker, but lets me control the one that is always too strong.

This works to level off the stronger inputs and increase the weaker inputs. I've used this on a combo of an Azden Shotgun mike connected with an XLR-3.5 and two Azden FM lav mikes. It boosted the lav mikes volume slighly enough to give me a clear input signal. With the Panasonic DVX100B, this works best because of the amount of control the DVX100B offers for professional audio recording. You should have this as an option for on-camera recording even if you have a separate recording kit (data-recorder, boom etc).

I bought it ... hooked a seinheinser MKE-300 mike into it, and plugged it into a SONY TRV-33 camcorder ... and I can't hear much of a sound (very very very very weak sound) even at the max range of the audio channel. Completely fails.

For the price, the Azden passive mixer is really too expensive! Behringer audio mixers offers two different mixers that are amplified, that I needed for the same price or less. Behringer mixers have so many options for the same price, that it makes the Azden mixer over rated! I returned the Azden mixer. If you don't need any preamps for your mics and want a subcompact package for your camcorder, then the Azden mixer works okay.

Haven't even got to use the mixer yet. As I ordered it as the 'additional items' to go with the lapel mics. Unfortuantly I thought I was getting to mics with the thing that I ordered, and it only came with one. Therefore, no use for the mixer yet. It seems very light. Needs to be attached to the camcorder, but it has a clip on it that you can clip to the strap on your camera, that seems nice. However it's pretty cheap plastic and might have potential to break quickly.
