So I am having trouble getting optimal sound quality to the Vixia HF R40 camcorder using a VidPro MX-L lavalier condenser mic running through a Behringer Eurorack UB1202FX audio mixer. Â I don’t have a mini to XLR adapter to be able to use the XLR input and the Invisible Mic Pre (maybe that’s my problem) Â I have the mic plugged into the Line in and tried tweaking the Gain and Level controls, and the Main Mix control which also adjusts Level, Â and managed to get a clean sounding signal but it appears to be weak. Â The board also has a PHANTOM power supply. Â The VidPro mic has aÂ built inÂ power supply capsule that is battery powered. The power supply can be switched off for use with aÂ smartphone.Â â€¨â€¨
if I get the mini to XLR adapter and run the mic into that input does that solve the problem? Â Or is something else going on? What should I try? Â Thanks!
Here are specs
Microphone Input (IMP “Invisible Mic Preamp)
Max. input level: Â +12dBu @+10 dB gain
Gain range: Â +10 to +60dB
Sensitivity: -30dB +/-3dB
Vixia HF R40
Unknown (but probably the same as the VidPro as the mic is a perfect match for the HF R40)
You are being silly! The mic inputs are for microphones, and the line inputs expect around 100 times the signal level – nearly a volt, but your mic provides microvolts. XLR inputs are designed for these low level signals. You MUST use them. You can buy adaptors, or solder on the proper connector – you cannot connect microphones to line inputs – it just won’t ever work!
