Panasonic Industrial Devices ERZ-V14D220 Varistor

what's up guys Biggio is oh cool stereo comm we have us a new device here for the test bench we have a Panasonic distortion meter or VP seven seven zero for PE I'm going to show you how useful this device is in conjunction with our Oh Scott and DeeDee one I want to show you how important it is to check your outputs over your head unit and make sure it doesn't have any Distortion now what we have here is an Alpine CDA 79-77 this is before they had the mp3 playback and stuff like that as you can see it says 4 volt pre out and what we're going to show you here with the distortion meter is we have the range set at 1% and I'll show you in a minute that we're actually going to change that we have the levels set at 10 volts so on this side the scale that gives up to 1 we're just going to multiply that by 10 so if it gets to 9 it'll be 9 volts instead of point 9 etc you can do that math I'll he
