So here's the thing, I have a dynamic microphone and an olympus ls-14. I know that dynamic microphones require no power to work, though even through a mic level input turned up to extremes, it's still really quiet.
It is most definitely audible but it's got some serious noise that I know is not fault of the microphone, this microphone can be made to sound really great if used correctly. The way I have this connected is a 3 pin xlr cable that terminates in a 1/8 inch or 3.5MM output cable that connects to my recorder. This might be a cardinal sin, though it's the least awkward way I can get this connected to the recorder. Lol.
I think the thing to do is buy a preamplifier, though I've yet to find one that is not a USB interface, don't want to be tied down to USB, or battery powered, I also don't want to be tied down to a wall outlet, neither do I have the electromechanical experience required to wire up my own battery module, which most preamps I've seen on the market under the $200 margin require.
I have in fact seen the sound professionals ones on there website but that at best only provides one single input. For future expansion I'd like at least two inputs for a stereo dynamic pair.
Can anyone suggest what I should look into? New recorder? New preamplifier? Something I've not mentioned? Like I said, I'd rather not be tied down to a USB interface or a wall outlet, this setup will be used on the go, and waiting a minute and a half for a windows or Linux machine to boot up to begin recording is absolutely not an option.
I hope this setup and explanations make some kind of sense? Thanks everyone!
It sounds like you're experiencing phasing. Your XLR to 3.5mm TRS cable is not designed to bring stereo signal in from a single xlr mic. However, instead, the TRS is used for stability of signal. If your input uses a stereo TRS jack to bring in left+Right audio signal, connecting a 3-pin TRS setup, like a XLR to TRS adapter for a microphone, to it will cause the channels to phase out. In other words, cancel each other out, basically, resulting in signal being extremely quiet.
@G-rad, I failed to mention it's really left heavy. I can kind of see why it's doing that, though I failed to mention it. At the moment I only have one dynamic connected to the recorder.
I did see, on amazon, a y-splitter cable that takes two 3 pin xlr cables and ends in a male 3.5MM output connector. I was going to purchase two dynamic microphones as a stereo pair and connect them directly up to the recorder using said cable, however I'm not sure if that's a particularly good idea or not.
