Audio panel connections

[Setthrust]

Initial installation of D1000 screens to my Garmin245 Audio panel. Each screen has 3 audio wires left right and ground….. i am confused as to where these would go in the audio panel . Comm1 , Aux 1 , alert audio?
I am running dual Dynon comms

any help appreciated.

I usually just connect to an unswitched audio input, you have volume control via the Dynon.

You will find guidance in the installation manual. Specifically, chapter 4, starting on page 4-33. The SkyView audio outputs are essentially alarms and the manual recommends that you feed them to an unmuted input to an audio panel.

Sorry for reviving this thread. But, I want to make sure I understand this.

So, if you're hooking up the audio alerts from Skyview to a 3rd party audio panel, you short "Right" and "Left" audio outputs together. And, if theres more than one Skyview display, you short the audio output from all displays together. And, it all goes to a single un-muted aux audio input on the audio panel.

Does that sound right?

Yes, you read the manual correctly

Maarten, I know this sounds redundant but I am getting to the Comm portion of my install and had similar questions that you answered here. For my own clarification, if I am using a single HDX screen I use pin 13 and pin 31 to my Unswitched pins on my PMA8000B. ie, send them to audio panel in stereo? Thanks in advance.

 

[maartenversteeg]

Correct, assuming that the PMA8000B doesn't have a stereo unswitched input. The Dynon 'warning' left and right outputs are just tied together, this doesn't cause any problem for these outputs. You connect these two wires together to an Unswitched input Hi. In addition you might want to connect the Dynon warning ground (pin 30) to the corresponding Unswitched input Lo on the PMA8000B

Just a thought - you may want to consider running the SV alarms through a switched input. I had an EGT probe fail, and it set off a master warning and played the audible alert 1545 times...I couldn't do anything to shut it up in flight.

Some discussion here about it:

Unmutable alarms and EGT curiosities

Hokay so, the other day an EGT probe wire failed in flight. The value started dancing around, then going off-scale high and low repeatedly. I now have two issues to bring up: Every time the failed EGT cycled, it set off a master warning and and EXHAUST GAS TEMPERATURE audible warning...

Yes, but that is a tradeoff every pilot has to make, once you switch off the audio from Dynon then you won't receive any alarm audio anymore, that may result in it's own consequences.
If you would change the configuration in flight (take the offending EGT out of the configuration) then you could selectively silence this specific alarm.

 

[lrg775]

Yep - which is why there absolutely needs to be a way from Dynon to easily inhibit an alarm. Everything else is some level of hack.

In my opinion...editing EMS configuration in flight, single pilot, with a single screen, isn't feasible.

 

[CanardMulti]

While I don't necessarily advocate for it, if a switch was put into the audio line between Skyview and the audio panel it would allow the pilot to choose to silence a nuisance audio alarm. Keep in mind, the visual warnings on the screen would still be operable for most other system failures. The choice to silence would be a matter of judgement for a pilot that understands his systems and would be dependent on the given situation. Example: With several hours to go to destination, would it be worse to lose audio alert capability (remember visual flags would still be mostly operable) or lose your sanity from hearing the same message thousands of times?

 

[maartenversteeg]

With several hours to go my desire would be to land at an airport and reconfigure, I would think. My missions don't have airports that far apart

 

[lrg775]

My 1545 alerts all happened in under 20 minutes, and sure made landing at a controlled airport fun.

You could put a momentary switch and a timer in to silence alerts for a specified time.

I'd install a way to bypass it though, just in case it fails.
