Topic: M248 users....

[Kevin]

Just picked one up last night   and had some questions.  How do I set up my equiptment so I run the mics through the 248 and then use the minime's A/D? Also, how often do you service the unit?  the guy I bought it from said I should send it to the oade brothers to get it checked out, not sure why, he hasnt used it in awhile.  Also have any of you modified the unit so you can use DC power?  How long does the internal battery last?
Preciate the help fellas

have not run one of these, but the internal battery should last you plenty.  just charge it overnight.  run short xlr's from the back of the 248 to the mme.  turn the mme's gain knobs all the way left till they click at line level.  you'll be controlling gain via the 248.

you may need to calibrate the mme to the 248...there are instructions on the sonicsense page for calibrating an a/d to a variable gain pre.

have fun +t for the killer new toy.

what damon said...

m248 batteries should last in the neighborhood of 6 hours on a full charge depending on the mic draw - and the condition of the battery.  If it hasn't been used in a while, send it to Oade, and they may update the circuits and replace the battery ($100 or so total).

The m248 has XLR inputs, RCA outs, no XLR outs - so you will need RCA to XLR cables to run to the Mme.

Mods have been done to run it on DC, but it really isn't necessary except festival time.  If you read up on the oade archive you will find that some people that have modded for DC have burned up their units beyond repair - I would not chance it unless you are an electrical engineer/real guru.

Enjoy the new toy - I love mine!  (but  do keep an m148 for festy season - and to have a choice)

it has RCA outputs?  wtf?

the inputs on the mme are some kind of bizarre universal input, i know they can accept 1/4"...wouldn't it be better to go rca to 1/4, rather than rca to xlr?

IMO Yes!

I'm not argueing here, just trying to learn; why would it be better to go rca > 1/4" than to xlr?

[dmonterisi]

i've never gotten this right, but i think xlr's are unbalanced and rca's are balanced and 1/4's are balanced?  i'm not sure what that means, but i think there can be humming or hissing or something if you are going balanced > unbalanced or the reverse.  somebody else who actually knows what they're talking about should chime in with real info.

other way around, maybe? this topic is not for me to poop on

+t for pooping on this thread

Actually Damon, XLR's are balanced. RCA's are unbalanced, and depending on wether or not is is a stereo or mono 1/4", they can be balanced (stereo) or unbalanced (mono). If making a cable that goes from balanced to unbalanced, at the unbalanced end, always solder the cold/low/negative (choose your preferred term) to the ground/shield.

thanks JB...+t...so that means it's better to go rca > 1/4 (unbalanced mono) when going 248 to mme?

It's such a small cable run that the issue of them being balanced or not does not really factor in. I'd go RCA.

[utahtaper]

You want mono RCA>1/4 unbalanced.

wouldn't you want to go XLR so they lock in the back of the unit?  oh, wait...
