M20M here i go again..chasing a Dre symphony issue and a20 vs a30 question

[pkofman]

My intercom worked perfectly in the '98 m20m when I flew it on Saturday, then I started the plane Sunday morning, and the headset would not provide any sidetone, and I could not transmit to ATC through the headset mic. I was, however, able to communicate with ATC on the ship mic and speaker, so the radios are all working . Then all of a sudden I had no sidetone and no comms with atc over the headset, I must have screwed up something, cant determine what went wrong.

SO; 

I need a Dre Symphony manual, does anyone have one they could send to my email

I need to figure out if I screwed up a setting and muted something

it could be the transmit side of the intercom, or the KMA 24

I either did something stupid and hit a setting, or maybe my headset was dead.

It is a tricky troubleshooting situation.

If it is my headset  ( an a20 ) , and if I have to replace it, would anyone here vouch for the a30 over the a20

there is a mooney group on facebook and lots of negative a30 comments.

All thoughts and recommendations appreciated

I’m not really any help, but if it’s definitely the a20, I’d send it back to Bose.  Last time I did that it came back like new for free.  I think there is a nominal charge if they are above a certain age.

You don’t have any other headset around to test with?

Very unlikely that it's your A20.

 

Very likely that it's a setting. The instructions for your DRE Symphony should be covered in the back section (AFMS) of your POH. 

If not here's a copy: https://www.mooney.com/wp-content/uploads/2020/12/DRE-Symphony.pdf

 

If it's not a setting on the DRE, I would look over all of the buttens and the knobs on your KMA24 Audio Panel. If it's not a setting, most shops will have a KMA24 Audio Panel on the shelf they can slide in and see if that's the problem.

yes, it was one headset, the mic not working, and no sidetone; then I tried that headset with my handheld and as well through the copilot seat plugs. I got mixed results and even some funky behaviour when using the PTT on the pilot yoke. 

Honestly, allot of variables to emulate the same thing I experienced, very frustrating 

I don't think it is the a20 either  . ill keep working on it. and honestly, I think I've screwed up a setting on the dre. That thing was pretty sophisticated in its day , but it is long past its best-before date.  I've had this plane for 7 years and never had this issue, so maybe my personal best-before date is coming up as well!

Thank you for sending this along, I know this is in the plane but I'm far from the machine today. much appreciated. I probably screwed up something without realizing it.

I've had the plane for 7 years and this was a first for this issue. Probably DRE or kma 24 pilot error on my part.

Thanks Peter
