Is there any benefit or drawback to using the XLR out from the receiver to the 1/4" input of an amp?

Reason for asking:I get slight but a noticeable background noise increase when using the line 6 XD V55HS receiver as opposed to a chord. I notice it when pluging the unit in to the amp. As soon as the plug is seated the noise increase happens. If I unplug the unit it stops. It's slight but still noticeable. I was wondering if using the XLR instead of the 1/4" would help. I haven't tried it because I don't have a XLR to 1/4" adapter.

Sorry. Didn't mention. I'm using it for guitar.

You should match the output jack type of the receiver to the input jack of whatever you are plugging into.

Are you using a standard 1/4" plug ... 2 conductor and not 3 conductor (TRS)?

Yes, standard 1/4"

So there's no grounding benefit to using the XLR instead of the 1/4" for guitar then?

Is it normal to have a slight noise increase when the receiver is plugged in? If not, "how" and "why" would it induce a slight hum into the system?

There is a benefit if the receiving end is balanced.  But both ends have to be balanced for the system to work.

Please try this test.  Instead of pluggin in your guitar short the end of the cable that normally plugs into your guitar (easily done with a paperclip).  Does this noise get lower or go away?

From the transmitter chord shorted: I get very very slightly more noise when shorted.

No one answered my question. Is it supposed to be slightly more noisy when connected? No guitar signal.

I would suggest to try with another cable.

Tried that. No change.

Yes ... about 2 dB.  Even extremely low noise electronics have some noise compared to wire only.
