I have the same problem using a Sony ECM-MS907 mic with a Sharp MT80 mini disc.
The line in suggestion does not work because the audio levels are far too low, the mic input on the Sharp is very hissy when the input level is turned up. This is really annoying because the mic cost £90. It sounded OK when I tested it in the shop. This was due to the background noise in the shop masking the hiss. It is really noticible when using in quiet conditions.
Can anyone suggest a way to PRE-AMP this mic cheaply? I've seen units on the internet that can do this but they cost anywhere between £90 - £200. I'm sure the components and circuitry would be pretty cheap.
Are there any techno heads out there who have built such a PRE-AMP unit after encountering similar volume problems?
