Do not buy the Brace Wireless system. Dwg1000x. When you turn up your amp real loud youll hear some constant noise. When you turn off the bass end of the receivers and leave the amp end on that noise will beep periodically instead of being a constant hum. Mine did that, so I took it back to the shop where I bought it. Did the same there, so I asked them to test a new set. Same thing. So they gave me store credit and I used it towards a new wireless system where I got like a one hundred dollar discount in addition. A nice half rack Peavey system. Much better. Test yours if you have one. Does it have the same problem?
