Have you disabled the aux audio input from the EFIS to determine whether that's the source of noise? I tried running an MX1 audio into a V16 aux and it was massively noisy. Re. comm mic quality. What mic gain did you arrive at for A20? I was surprised at the degree of attenuation needed; something ...

I have a couple of issues happening to which I have done as much trouble shooting as I know how. The first issue is that I have noise that seems to be associated with EFIS screens. It is a ticking static noise that changes when I flip through the different EFIS screens. I have Tried several differen...

Just wanted to update this post. I have resolved the issue with rpm readings. So I’ll list my settings for those that are using mgl rdac xg with a dual Pmag ignition setup. All rpm dip switches on rdac are “off” rpm 1 on efis set to 1 pulse per revolution. I had to use eicad program from emag and wi...

Just seeing this! Yes to your questions. I am using rpm 1 in the menus. And that is the case, that no matter what I set the pulses to it reads about double. With the diode installed it reads zero so the 12v signal is when it reads double the rpm give or take. I purchased a oscilloscope and checked t...

I am hoping someone here could chime in with some settings or something. I have a dual PMAG installation, the units I have spit out a 2 pulse per revolution signal at 12v. They include a diode to install between pin 6 and pin 1 to drop voltage to 5v. I have the RDAC set up from the efis at 2 pulses ...
