Does audio impedance transformer help with noise with Dynamic Mic & digital recorder

Good evening.

I have a Sennheiser MD 46 microphone hooked up to a high impedance recorder Sony ICDPX333.

I have to set the mic input to Medium, but I grab some noise. A B&H representative told me to use a Low to High Impedance Matching Transformer to bring the microphone low signal to a high signal needed for my recorder.

Will that make it possible to reduce the mic input to Low therefore reduce noise ?

Thanks
 
Same answer as on your previous thread a couple of days back.

Messing around with matching transformers would be throwing good money after bad. Your recorder is for use as a dictaphone, not for any sort of quality recording. I doubt the change that a transformer could make would even be audible compared to the self noise in the ICD PX333.
 
Thanks Bobbsy ! I was asking because I've been shopping around for another recorder. I would love to be able to record from the internal mic at the same time I'd be using the external mic (picking up ambient sound on a separate track).

I was reading this Tascam DR-40 | Transom

There are good tests further down the page, and the guy shows that it has the same problem as I do with my "el cheapo" dictaphone.

So I was wondering... even though I have a good mic, it seems like the ones that really can do a good job are high end like the Sony
PCM-D50. Good sample using various setup and recorders : Portable Recorder Noise: The Sounds of Silence

Talking to a Radio Canada journalist, she told me they mostly use the PCM-D50 paired with a Electro-Voice microphone.

Thanks for any advice that could help me make a proper decision. No way I can spend that much on a recorder at this point.
 
What are you trying to record? Voice only or music? Have you looked at the Zoom recorders?
 
Good day Mike,

On the field interviews with ambient sounds capture. It's for audio documentaries. I currently own a Sennheiser MD46.

I was comparing both the Zoom H4n and the Tascam DR-40, both seems to have that noise when using external dynamic microphones...
