Thanks Maxmobil....
Sorry about the 2.5mm - it was a typo. 3.5mm is correct.
Would like to record in a PA34 and B737-200.
The impedance mismatch is what concerns me the most. The spec for the mic input is:-
0.388mV low impedance with 2.5 to 3.0 V DC, output impedance 6.8K Ohms.
I'm looking for some kind of suction mount, but not sure if I can justify the (high)expense I've so far encountered! The camcorder only weighs about 700g.
Thanks again for your help.
Eric
