The audio output device needs a compression circuit to keep audio levels
more near a constant output. There are portable cd players out there that
have such a feature.

Your headset may have a dip switch that's factory set to mono-out a stereo
input - like the Bose headset. Try the other setting. Or it may be wired in
mono. Try it on a stereo source at home.

We need you to fix that, Jim. When you're done, will ya do something about
that Iraq situation and Global Warming?

I'd rather he'd work on important stuff. Like, no alcohol on mogas
in California so we can use the stuff in our Skylanes.

It's been done. Instead we got the current example, who mandated that
the fuel leaves the refineries with the alcohol already mixed in.

Jim, would you consider adding to your product line a device that feeds
music into an individual aviation headset. I would bet you could design
a pretty stout, useable device that would be superior in quality to, and
more reasonably priced than, the PSE Muse. I, for one, would be
interested in buying such a device.

Happy Flying!

My iPod *does* have an audio compression feature, and it is turned on.
Quite simply, the minimum audio signal required to power up the Muse is
higher than I would like it to be.

No switch on my headsets, they're good ol' mono DC's. Knowing that the
majority of aviation headsets are mono, PSE incorporated a mini switch
inside the Muse, to provide either stereo or mono output. The position
of said switch has no discernable effect on the music I hear in my headsets.

Aviation headsets have notoriously higher impedance than the typical earbuds
that come with Ipods and other consumer audio devices. Might be an impedance
mismatch requiring a matching transformer.

Ummm, yeah. And since the Muse is *designed* to input consumer audio
devices into aviation headsets, I would expect the built-in circuitry to
handle this just fine. IMHO, it does an "O.K" job, but not as good a
job as I would like.

Without me doing a lot of research that most of you seem to have done, what
is the input, what is the output, and what is the function? And no, I won't
do stereo. There are good reasons.

******************************

Stereo In The Aircraft

RST does not produce any stereo intercoms, audio panels, headsets, or other
devices that

reproduce stereo music. If you are absolutely determined to have stereo in
your aircraft, you

might just as well stop reading now, because anything we have to say isn't
going to change your

mind.

We made a conscious business and engineering decision not to produce any
product for stereo.

There are good aviation and engineering reasons for this.

First, a little background music or listening to the ballgame in a cockpit
environment isn't all

that bad. Sometimes flying is miles and miles of nothing but miles and
miles. On the other

hand, I know from my own love of music that when there is a particularly
good cut playing on my

home stereo and I have the headphones on (try "Sweet Sir Galahad" by Baez or
"Minstrel Of The

Dawn" by Lightfoot at somewhere slightly below the threshold of pain in the
'phones to see what I

mean) that I get totally lost within the music and the world just sort of
blurs away. Just

about the LAST thing I want in an airplane is a pilot that has zoned out on
music and is just

holding the controls to have something to do with their hands. That's item
#1.

Second, stereo is expensive. Yes, I understand that FLYING is expensive,
too, but to go to the

expense of specially-designed headphones, intercoms, audio panels, and all
the rest of it seems

to us to be on the other side of reasonable. Our company thrust has, and
always will be, to make

flying affordable for everybody. That's point #2.

Now to the engineering stuff. Suppose you try and take your stereo headset
and fly in somebody

else's airplane that is "regular airplane". Will your stereo headset work
without the trick

little switch on the cable to convert it to a monophonic headset? No, you
will hear one ear of

the conversation only. And what did that little switch do? It put both
earphones in parallel,

which cut the impedance of the headset in half. Properly designed, this
MIGHT not be noticeable

to the aircraft radio, or it might. Since airplane radios weren't designed
to figure out whether

or not you were messing around with a stereo headset, the manufacturer
didn't worry about making

sure his radio would drive that low of an impedance.

Even worse, if somebody else takes his standard aircraft headset and puts it
into your stereo

airplane jack, it will short out one of the channels. Depending on the
design of the intercom,

the best you can hope for is that one stereo channel will be dead in
everybody's headphones.

Second worst is that the short on that channel will blow out the amplifier
for that channel. In

a really lousy design, that short will cause the whole intercom/audio panel
to fail, leaving you

without any headphone audio at all.

Given all these reasons, RST has decided not to produce any stereo
equipment. While it probably

won't sway your decision for stereo in your airplane, we thought you should
at least consider

these problems.

Not sure I can follow. All your points except no. 1 have been solved
quite well by most all other companies in the business, and the price
delta has become real small. For headsets and audio panels, stereo is
the de-facto standard now. And no. 1 is really not your decision to
make, is it? It's the decision of the customer. But, if that's the way
you want to do business and it works, by all means do it.
