Thanks for the info. If I lay out the money for the MR-1 it may take a while before I can get a pre or a batt box to power the mics, so it's god to hear that I can use the 3v power of the MR-1 (though not ideal) until I can get an external power source.
I have the mics already. What is the advantage to having them modded vs using an adapter? How much should I expect to pay for such a mod?
Advantage of having mic naturally terminate in two miniplugs is one less mini-connection to maintain as fully connected and very free of noise-inducing fingerprints (these need wiping clean before connecting up).
Disadvantage with having mic fixed with dual plugs is now your mic cannot be easily used with better powering than provided by MR-1 deck, and mic cannot be used with
any other model of deck if you desired to do so, or at least without dual minijack-to-stereo adapter to convert back to ministereo plug like you have now.
