I have owned and operated dozens of sound systems for over 40 years, and have never had problems or heard of any damage to any equipment or electrical shocks to any other musicians as a result of using ground lifters. If the surge encounters a high impedance return path i. It often occurs that the soundman will have the PA set up and running, with no hum, and then at sound check a hum appears, caused by something you introduced into the situation. However, don't shortchange yourself. Relevant facts were ignored.
We exhibited at 3 Global Sources trade shows View More. September Learn how and when to remove this template message. It is a hum that musicians learn to recognize, and it's part of troubadour field training to learn to deal with it. Looking to fast-track your sourcing process? For example, IEEE waveforms are standards for discussions such as safety standards.
Is it safe to plug a surge protector into a two prong to three prong outlet adapter : buildapc
I have two pieces of Marantz HT equipment that I am using aftermarket 3 wire power cords on. Again, a three prong cable will be just fine. This page was last edited on 30 March , at I know you posted this question several years ago, but others reading this may benefit from this information. Ltd 1st year China mainland Response: Let through voltage did not exceed V certified by UL.
I would also make sure the wire gauge of the power cord is at least 12awg. Fears are created by a series mode protector manufacturer. At least 20, amps must connect non-destructively low impedance to earth. Can this be done inexpensively? The true cause of it can be impossible to determine during the time period you have to deal with it when you have a gig, but it generally means that the wiring in the venue is interacting with your gear in a detrimental way. I find myself wondering if some place like the Berklee College of Music is graduating musicians without ever dealing with this subject, which I feel is of vital importance to any performing musician who uses amplification.
