I have been busy upgrading the tailBeaconX control head by adding touchscreen capability and audio output. It now has completed flight testing and is available from MakerPlane.
New touchscreen version of the huVVer-AVI with the TBX App...
You could use a single resistor to audio ground and tie Audio Out Left and Right together At point A. I show independent resistors for stereo intercom systems to support the possibility of future stereo warnings, like OnSpeed AOA systems use.
A solution to SkyView noise is to terminate the audio outputs of the EFIS with 10 ohm resistors to ground. This will attenuate both audio alerts and any noise, Then, increase the audio level in the SkyView settings.
Some of the of the noise that you are getting may be from the dimmer circuitry...
For listen only (backseat pax), just connect the pax headphone phone jacks in parallel with the copilot or pilot phone outputs from the intercom. Do not connect the pax mic jacks to anything. If you want to listen to the pax, things get more complicated, requiring a mixer and more circuitry...
Here is an application drawing for the AMX-2A. MakePlane also sells the AMX-10A that has both mono and stereo inputs. FMI

Original build: Vans RV-9A.
Second build: Harmon Rocket.
Current build, with 5 hrs flight time: Rans S-21.
All Dynon based…. D10A….SkyView…SkyView HDX.
The panel photo shows a set of discrete flight instrument that interwork with the SkyView system, including an OnSpeed energy display and a...
I purchased a 12V, 30A power supply and adjusted it to 14V. I connected a 7A breaker to the output to make a GPU.
I charge the SkyView battery by plugging into my 12V 'cigar lighter’ port and pulling all of breakers except the SkyView and 12V port power.
To simplify, I also fabricated a...
PS Engineering makes the Dynon intercom, Trig makes Dynon radios and transponders, and I make the MakerPlane audio mixers… so a brand does not always signify the actual manufacturer. Not a criticism or endorsement, just an observation.
Here is a simple bypass circuit that plugs into the intercom harness when it is removed. The rightmost image is the actual wiring. If you really want to go to the extreme, it’s also possible to incorporate the SkyView audio alerts into the design. I could tell you how, but it involves...
I have had multiple conversations over the years with Dynon reps on this very topic. They inferred that Trig, who makes their existing transponder brick, would have a solution. I couldn't wait, so I met with uAvionix and helped convince them to develop the tailBeaconX, then I participated in...
The LEO satellites will pick up Mode-S/ES transponders with a conventional bottom mounted antenna, but the best reception will be when the satellites are close to the horizon, rather than overhead. To ensure full coverage, either a diversity transponder with top and bottom antennas, or a dipole...
I am the designer of the AXIS-25A. Dynon's harness does not terminate on a 37 pin connector unless you add one. In the case of the AXIS-25A, all of the required bussed interconnect between two SkyViews are handled with 25 pin connectors. This provides all of the required fail-safe interconnect...
