I have great audio and clear warning messages. One thing that I did that was different than the plans was I installed isolating washers on all four audio/headset jacks in the airplane. In fact, my wiring kit didn't come with these and I had to order two sets. From my experience in wiring other aircraft, I knew this was critical to getting good audio in the airplane. I did make a few adjustments to the audio pots and to the GTR200 audio levels per Van's guide to get the levels where I wanted them.

I also re-wired the music IN jack between the seats per Garmin's recommendation in another thread. This also improved the quality of the AUX music played from my iPhone.

I can't say for sure that this will correct your problem, but I still highly recommend these changes.

All headset wiring had been verified as correct with the drawings and isolate works as designed.

I used the instruction in the latest prints 42D-30, and set all of the pots as listed, and I have the Volume control / test setting in the Skyview setup menu and 100%. I then began increasing the L & R EFIS trim pots to get some alert volume. This provided minimal gains in volume, and continued to degrade the clarity. Basically resetting the other trim pots had no effect. I did note one additional piece of information that is interesting. If I turn off the SL40, the headset background noise is reduced, but also, the alert volume level drops, as well. Man, I wish I could get a handle on this. I do have a plea for help via email to Van's support. Be assured, if I get anything good, I will post it..........Tom

Randy, I am really not unhappy with my headset performance, and I have the headset jacks installed as per the plans. Everything except the Alerts come through just fine. The intercom, SL40 reception, and side tone, even the stall warning is great. It is just the Alerts from the Skyview that are unacceptable, and that includes the AOA beeps. Although I did disconnect the music jack wiring that I don't use anyway. That did eliminate some extra background noise...........Tom

In an effort to effect some change in my Skyview alert volume, and clarity, I starting with the AV50000A setting to factory specs. I then reduced the stall volume, thinking that just perhaps the mixer was being overdriven. With the volume setting on the stall trim pot at 100%. the horn is very loud. Reducing the stall volume to a low level had no effect on the alert volume, nor the clarity of it. Willing to try anything............Tom

Have you looked at the volume setting of the alerts within Skyview? I thought there was a setting in the set-up area that allowed you to control the volume? Maybe I dreamed that.

There is an overall Skyview volume control in set up. It comes preset at 100%, which is where mine is set. Then there are the 2 trim pots that control the EFIS R, and L volume settings on the AV50000A. In fact there are quite a few trim pots on the AV50000A, and mine are all set to the specifications in the latest section 42D of the prints. That is all I know of, but thanks for your thoughts...............Tom

Default Skyview Alerts FIXED

After much wire tracing, gaining a better understanding of the wiring drawing, and a little help from Gus at Van's, my Skyview Alert Volume problem was identified, and fixed.
After completing the avionics installation, I noticed quite a bit of noise coming into the headsets. I posted a query on the forum, and it was suggested that the noise was probably coming from the music jack wiring in the cockpit, and that by removing the music input leads at the intercom, the antenna effect from these music leads would be eliminated. I then disconnected pins 18 and 19 from the intercom end of the cable, and sure enough, my headsets were no longer noisy. The problem was that these are the same wires that the Skyview uses to broadcast the alerts. So, I have now reconnected the music leads to the intercom, and balanced the inputs from the skyview, through the AV5000A, and everything works as planned. So, if anyone else has removed, or planned to remove the music wires from the intercom, you had best rethink that idea, or you will surly lose your alerts.

I know that I have read of others going down this same path, and I hope this post helps......the end.......Tom.

Is this correct:
So the music wire starts between the seats, heads forward, and goes INTO (!!!) the AV5000. The Skyview alerts also go INTO the magic box.
Inside the magic box, the music and the alerts get added together into a wire that goes FROM the AV5000 INTO the intercom and that combo signal I s adjusted by a pot.

Right?

So what about disconnecting the music wire where it goes INTO the AV5000? Wouldn't that remove the interference without deleting the alerts?

Yes Bill, the music, and the alerts are mixed in the AV50000A, then exit the AV50000A, and go to the intercom music in pins. You can balance these inputs with the individual pots; EFIS L & R, and Audio L & R. You can also set an overall EFIS volume level, and some others, in the Skyview > Setup > Volume screen.
I sure learned all of this the hard way, but I now have a very well balanced alert, and music system. You can get some terrific help in doing the balance by following the steps in the latest section 43D, and in particular, page 30. Hope that helps..............Tom

Hi Tom, - Thanks for your investigations into this matter - I am one of those who took the music input pins out of the intercom to get rid of the hash & noise which I believed was coming from the music input system. I thought I had solved everything until I read your posts about the Dynon audio warnings, and I am about to put those wires back.After that do you think I should turn the music input pots right down or off, ( I don't think I will ever need music!)? It seems you have had success balancing the EFIS R & L pots with the main EFIS volume. I don't have the same drawing as you, mine are on pages 45A-10 & 11. I guess the instructions are the same. Thanks, DEAN...
