I just purchased this for my Olympus LS-P2. https://www.kvconnection.com/product-p/km-ad-trsm-a32.htm

That should lower the input, reducing sensitivity of the mic-input to something more like a line-input.

I'm wondering if using this cable will turn stuff intended for line inputs for the mic input, like battery boxes. I say this because every time I put my battery box in the LS-P2 mic input, it suddenly sees it as a plug in power device and there seems to be no way to turn that off. [/quote]

There should be a switch in a menu somewhere to turn PIP on/off.  Regardless it should not effect the recording if PIP is left on and you plug in a battery box.

I have checked everywhere inside the menu of this recorder and no, there is no option that allows you to turn off plug in power.

The battery box has capacitors in the signal path past the battery which block the DC provided by the battery box to power the mics.  Those same capacitors also block the PIP DC provided by the recorder from reaching the battery or microphones.  Shouldn't really matter if you can't find a way to turn it off.

What may matter is the impedance of the attenuation cable and how that interacts with the output impedance of the microphones through the batterybox.  Depends on the particulars of both the cable and the microphones, but in some cases could create a filter which produces an unflat response.  Listen for a change in high frequency response when using the cable. That's less likely to be an issue if using that attenuation cable with a preamp or soundboard input.  Someone more electrically astute will have to explain this in detail, as it is reaching the limits of my electronics explanation comfort zone.
