bill Posted November 28, 2007 Author Posted November 28, 2007 tell me it doesn t create sub harmonics at 20, 10 KhzWhat is this ???This item looks cool too http://www.robot-electronics.co.uk/shop/Serial_Interface2110.htm :)
cimo Posted November 28, 2007 Posted November 28, 2007 tell me it won t interfere with audio (as audible) signal and i ll buy one, this guys use to emit slightly audible frequencies, thus useless if you are using instrumentssimone
bill Posted November 28, 2007 Author Posted November 28, 2007 aah, ok, sorry it was unclear to me...so, i dont know yet if they 'sound', but, for a live performance, unless if you are using microphones of course,it should not be a problem !
