Mixer for Sony VX-2100
 

Hi.
I have a VX-2100. I have a Rode Videomic and an Azden wireless lav mic. I am shooting a wedding and I would like to be able to mix these mic signals. I bought the Azden CAM3 but it does not work correctly. The signal is substantially weaker and almost unusable.
Is there another 1/8" pin mic mixer - preferrably not passive - that I could use to mix these mic signals?

Thanks
Jim
