Battery Module and Microphone problem

[Kuoi]

I'm dissapointed.

I've bought a battery box and still have some problems ... or can I say ... MORE problems than before

I've tried to record a gig last weekend , but had to low signal.

Somebody pointed me out , that it's kind of normal with a battery box , so...I've tested it today to be sure .

IT'S MORE distorted than WITHOUT the battery module.

I don't dare to buy a SP-CMC-2 microphone now, because my friend tested it too , with his mic. , and had the same problem.

My equipment:

SHARP MD-MT99 minidisc recorder

The Sound Professionals SP-SPSB-3 battery module

Vivanco EM216 Microphone

My microphone specifications , for what it's worth:

Frequency response 20Hz–20kHz

impedance 600 ohm.

I didn't used the 'pre-amp' of this microphone - because I don't want to destroy the BB - when I've tested it , so if

this can be used , and IF this should fix the problem:

How can I connect it to the batterybox ?

1 ) Minidisc > Batterybox > Pre-amp > Microphone

or

2 ) Minidisc > Pre-amp > Batterybox > Microphone

And I've 'updated' the pre-amp to a 9 Volt pre-amp instead of the original 1,5 Volt

Should 1,5 Volt be enough - because it's a bit smaller to wear then - If this can fix my problem that is ??

If I should know that it will work fine with some other microphone (cardoid) , I'll buy it IMMEDIATLY , but who can asure me it will ?

WHO CAN HELP ME OUT ??

BTW : Sorry for the capitals.

Greets , and many thanks in advance , Kuoi
