Uafx amp simulator pedal hiss

[Elston gunn]

Hi,
My question is about the UAFX amp simulator pedals, I have the Dream but I assume it would apply to all of the models.
I am using it on a live gig with IEM’s. Also might be relevant that I’m using a cordless radio pack on my guitar.
The clean sound is working great, but when I engage any of my drive or compressor pedals there is loads of hiss. (I’m powering all pedals including the Dream from a pedal power 4x4, so I think each one is isolated?) I think the pedals are all true bypass, there is no buffer. (Forest Green compressor, analogman kot, mason sd9.) The hiss is not affected at all by whether the guitar volume is up or down - I can mute the signal from the guitar but if any of the boost pedals are engaged there is still extreme hiss.
Is there any way to deal with this? Might a buffer pedal solve the issue? Many thanks in advance.

What I would do:
1. Make sure you are providing enough power to the Dream: 400 mA. I googled Pedal Power 4x4 and I see that there are several 9V 400mA outlets. Make sure you are using one of those and not a 100mA.
2. Try bypassing the wireless. Go from guitar to Dream, then to interface, mixer, etc. See if the problem persists.

Thanks for the reply.
I am using the 400mA outlets.
Yes bypassing the wireless sounds like a good starting point - I‘m in sound check this afternoon so I’ll give it a go.
