Marty I have to disagree with your statement that there has not been
any problems since.

When I first bought my Stereo Zaxcom in 2004 I had problems where the
TX output would rise as much as 10 db when the TX would go from being
cold (around 40 degrees) to room temp. I've sent it back twice for new
more stable photo cells and now it is much better but I still see a 2
to 3 dB fluctuation over a smaller temperature differential. I am
surprised that other people don't see this dB rise and fall. I wonder
why this is? So I am still having to re-calibrate tone regularly. I
wish I didn't have to do this but I was told by Zaxcom that 2 to 3 dB
of fluctuation is within there tolerance range. I use my Zaxcom for
all my run and gun jobs, which is almost every day I work. I can't
imagine going back to being tethered to the cameraman. The Zaxcom
Stereo system has excellent audio quality and only once have I had a
drop out problem and that was in Washington, DC during the last
inauguration.

he is asking if the zaxcom tx will short his audios range in the bag , so
Billy is not really the right place
probably yes , if you choose close block , probably not if you use filtered
antenna from zaxcom

Thanks for the clarification again Glenn. I know Marty is a reputable
dealer, but I just wanted to clarify from the manufacturer. I know
Marty has a couple of packages available and I may contact him soon one
I secure the funds. Thanks to everyone for your help and bay all means
dont stop the on the job experiences coming for this post.

Thanks all,
Rob
 >> Stay informed about: Zaxcom Stereo Link 

as I know the stereo line stayed as before without changing
if iam not mistake Glenn stated it few months ago
and really I never had any levels changes problems
the problems of level changing as I understood where in the receiver unit
and not the transmitter
so if they gone -they gone , you will buy the same receiver for eng type as
it was 2 years ago with newer firmware
maybe Glen can correct me if I wrong

After conferencing with Glenn this morning, I can now confirm that there
was indeed a recent change in the design of the Stereoline transmitter
that increases its efficiency. There are 3 differences in the new
design: the RF output is fixed at 60mW, the current draw is
significantly reduced, and it runs cooler.

These are benefits derived from the design work on the new TRX
transmitters (for clarity, "Tx" is not a specific model, but an common
engineering abbreviation for "transmitter").

I have also verified that the audio gain drift that a few users
experienced was due to the early photo cells that were used. The current
photo cells have very little inherent drift. And because the
transmitter's heat output has been reduced, only ambient temperature
changes are likely to cause any drift at all. While not ideal, the use
of photo cells has many benefits and the very low noise floor of the
Zaxcom system makes a 2-3dB variation in program audio level
inconsequential. It should always be S.O.P. to check and recalibrate
reference tone periodically (each tape change, etc.) anyway.

We at Zaxcom agree and think it is a big deal as well. The two changes
we have made to our stereo transmitter have eliminated this as an issue
on all currently shipping units. We have swapped out the photocells on
the few units that were out of specification. We use very few analog
circuits in our products but there are a few. Minimizing the varation
due to temperature can be difficult and we are aware of it importaince.

With the greatest of respect Marty, you obviously come from a very
different "slippery" world than I do. A reference means exactly that.
"each tape change" check hardly defines/inspires confidence in what
one is putting to tape. And I rather think that you'll find this
anomaly is not restricted to just a few users.

I gotta agree with Grant on this one.

I, too, consider a 2dB-3dB variation to be significant. If, when I
check the cam level at each tape change, I see that much variation, I
want to know where the problem is. Did the level controls get bumped?
Then I need to tape them. If it's something in my audio chain, I want
to know what needs repair at the first available opportunity.

Sure, 2-3dB more of less of S/N isn't anything to worry about, but
having levels fluctuate arbitrarily is.

Yes, for some of us, it's a big deal.

Glenn,

Thanks for clarifying this. According to the new specifications what
will the allowable level variation be?

I entirely agree. Any level variation in the audio chain is something
for concern. But I check levels at each tape change regardless, looking
for variations from any cause. It could be control knob changes,
differences in (analog) tape response, or even transcendental /aural
/arrogance pressure changes in the room.

C'mon Marty, what does analog tape response have to do with it since we
set the video camera levels via meters that measure signal going to tape
-- not playback. (Just tryin' to keep you honest, here.)

Now on the transcendental /aural /arrogance pressure changes in the
room, you nailed it. Those are the toughest -- and most unpredictable
-- areas we all have to deal with.
