Compact mixer pre into Zoom R16?

The 'like touching the end of a jack lead' comment strongly suggests to me that you have a system without a proper ground connection.

This is surprisingly common these days as more and more equipment uses class-2 (double insulated) wall-wart style power units.

Often, the recorder will pick up a solid ground when connected to external class-1 (mains-grounded) devices, like many powered monitor speakers, so you could experiment with connecting the R16 to something else just to get that solid ground connection.

I think that might be an idea. The 3rd pin is plastic so not used (UK style plug). It may be the issue but is consistent across many buildings i've used it in. What would i connect exactly? I don't notice a specific ground pin screw like some devices have.

would a ground lift work in the XLR path? https://www.amazon.co.uk/Hosa-GLT-255-Ground-Lifter-Adapter/dp/B00FC4YPL4
I'm just imagining the amusing site of a long rod of XLR connectors if i attach this to my fethead and then my external phantom power :headbang:

Do you have any gear that is grounded that you could plug into the R16? It doesn't have to be in the signal path or even switched on - just connected.

I see. Probably only guitar amps but I will check. I'm sure there would be something... as long as it uses the 3 pins I am guessing, not e.g. an effects pedal.

Worked. Thanks.

I only have the 50kg option of my combo amp though.

Does anyone know a cable/connector device that does the same? Perhaps a preamp that is actually earthed for cheap if not?

One thing to check with products like this is that the ground is directly connected. Some have a high value resistor between the ground pin and the terminal as they're often intended to reduce static rather than as a direct ground connection.

Indeed. The product in that review provides a solid ground, and I reviewed it because that is unusual. Most are intended for static protection and include a high value resistor, as you rightly say.

If that's just a connection straight to ground, why not just rewire a standard UK plug with a TRS cable? It seems like there's the same work either way (or in fact no soldering with most plugs). (Or will I die as a result lol)

The Groundology plug has non-conductive line and neutral pins, making it inherently safe under all conditions.

Wiring a ground lead into the earth pin of a standard mains plug would do the same thing but isn't inherently safe... And hence it's not an approach I can openly recommend on a public forum to people of unknown technical competence. But I do have some equipment here wired to ground using that kind of technique....

Found out the studiospares valve preamp sells to next to nothing used...and has a ground pin. so should earth everything (and hopefully be useful for more gain much like OP suggesting). notice its impedance its super high (but engaging phantom lowers it) so might improve ribbons and dynamics a bit too.

My 2 cents...

I have a Zoom R16 and record all my instruments direct to the unit mostly dry and or the odd wet track. After I recorded all the instruments to the Zoom I move my SD card from the Zoom to my computer and use the Reaper DAW to mix and add effects etc. For myself, this method works very well. Then if you wish, transform your finished WAV file to a MP3 file and upload to YOUTUBE. Or other Web based platform you would like to spot light your finished product.

and remember...clones are people too.... :geek:
