Query: Barely hear anything

I dont know if its working well together with a video cam, but I was using it on two different computers with 2 different connection (one with built in analogue interface, the other with external m-audio USB interface) and all I see is that the ATR 25 is not producing acceptable volume. The resulted recording is so quiet I can barely hear anything when playing back, and this I was speaking into the Mic touching my mouth and knocking on it and all Mic levels in system and recording application set on max and tried with a new battery. It seems this Mic needs a preamp to work fine. But I have none here to try it.
