Thanks for the reply Ty,
That is what I thought until I read this in the Beachtek DXA-4p’s operating instructions before I posted my question:
“The auxiliary input allows you to attach wireless [my emphasis] microphones that use standard mini-plug connectors. This signal is sent to the right channel…”
“AUX Input
To attach audio devices with mini-jack connectors, use the AUX input on the adapter. This sends the signal to the right input and you should therefore disconnect any cables from the right XLR connector to avoid interference”
Putting this together leads me to ask is the way a wireless microphone sends a signal via a mini-jack output different to the way a hardwired mic like the Sennheiser MKE300 does? Hard for me to understand how this could be possible as I guess if I just plugged the mini-jack of a wireless mike receiver into the mini-jack input socket of the camcorder the wireless mike would interface with the camcorder same way as the fixed mike, would it not? Does the wireless mike receiver have some sort of built in amplifier that the fixed mic does not?
Maybe I have no other option than to buy an XLR/mini jack converter and see if that works, which I guess it will do, though a big XLR jack would further increase the size and reduce the portability of this little system.
