After learning that our school is updating two of our older aircraft I started researching the items that it will include. One of the things I came across is Garmin's new audio panel.

The 350/350H includes a new Garmin technology called 3D audio. It basically assigns a spatial dimension to the different audio feeds. COMM 1 is only heard on the left, COMM 2 on the right, Pilot and Copilot depending on which one you are, and the rear pax depending on their relative location.

At first I thought it was some cheap "audio candy" to get people to upgrade. However, after listening to their example video I'm a believer! You can actually listen and follow every conversion with ease. I never thought my brain could do it that easily. :yes:

Take a look. Use headphones! :yes:

I'm hoping this is the audio panel that we get. Right now I'm thinking it's either that or the older GMA 340. I won't mind the 340, as I like it a lot. We have it in all of our IFR Maules and our two Arrows.

From what I've heard we are upgrading to the following:

Touchscreen 430 replacement. I'm guessing the GTN 650
ADS-B in and out- Most likely the Garmin 88 box
Digital Transponder - Most likely a GTX 327/330
Dual Head CDIs
 
If you don't get the 3D thing (which does sound pretty cool, but still...), try the PS Engineering PMA8000B or BT; you'll never consider the GMA340 after that.

We have the 7000 models in some of our aircraft. I like them a lot.

Dear ARFlyer (didn't find your name in your profile):

Thanks for your kind words about your PMA7000B audio panel. Last week (Tuesday July 15, 2014) we made public a product that we have been developing for quite some time.

The new PMA450 audio panel has what the USAF called Multi-Talker. We licensed this patented technology and call it IntelliAudio(R)

There is a simulator of IntelliAudio and for the PMA450 itself at www.ps-engineering.com/PMA450.shtml

You can place Com 1 and Com 2 in any one of the 9 places in the stereo headset, all by the front panel using the graphics display.

If you are going to be at Oshkosh this year, I'd love to give you a live demonstration. We are in Building D across from Garmin.

P.S. It of course, has our IntelliVox as well, just like your PMA7000B
 
The Garmin 3D sound is not quadrophonic, quadrophonic was a marketing gimmick to sell more speakers. It never took off.

The Garmin 3D sound literally allows the ability to have multi-audio streams going at the same time and be able to 'choose' to focus on one or the other inside your head.

It's akin to being able to pick out one persons voice in a party room full of people despite the buzz of the whole room talking.
 
No, quadraphonic was a gimmick to give much greater dimension to music than stereo could. The gimmick's still around and now marketed as Surround Sound and people pay far more for the systems now than they ever did then.

Quadraphonic had a brief foray and had a few cool albums recorded in quad.

My best friend had a Panasonic quadraphonic sound system in the mid-70s. Deep Purple recorded "Machine Head" in quad sound, and "Smoke on the Water" sounded...amazing.

I think he paid $450 for that set up in 1974-ish. What's that in today's money?
 
In the end it's just games with the amplitude and delay to each ear. I can't believe that they had to LICENSE it. LOL. I'm pretty sure anyone could fight that patent with prior art by showing off any old stereo with a balance control.

I'm pretty sure those old stereos didn't let you move all the string instruments to the left channel and the brass to the right, then adjust volume for each independently.

Big day today, we received FAA TSO on the PMA450, shipments will begin on Monday July 28th, opening day of Oshkosh 2014

Depends on what gear you had, but yes. Really isn't that difficult. Sound stages and the tech to create them have been around for 30 years. Even a cheap SoundBlaster card in a PC could do it in the early 90s using only two channel output.

It's interesting that someone finally played with it in a cockpit audio setting, but not new tech by any stretch of the imagination.

A good audio engineer could move any instrument or vocals anywhere they wanted them on a two- channel soundstage.

Thank you iHenning!

We now have everything up on our web site. For those who want to listen to IntelliAudio, click on the IntelliAudio simulator link. Be sure to wear stereo headsets and place the com audio signal in various positions.

Www.ps-engineering.com/PMA450.shtml

But if you have any questions, I'd be happy to help in any way that I can.

I didn't say it couldn't be done, period. I said that a stereo with a balance control couldn't do it. It's dumb to compare a digital audio card or a sound engineer's mixer board against a rheostat that only changes the relative volume of pre-recorded left vs. right channel information.
 
Last time I recorded something in a studio we were working on 2" tape...
