Hello ,after doing some research in the archives here,I performed the
key test on a SK 5212 tx.That is walking around a room dangling keys
while someone speaks into a lav mic plugged into the tx not far away
from the keys.I used several mics,the cos11,tram and mke.All of them
failed,they all sound as if the keys were causing some kind of high
frequency distortion even at low gain...or at high gain for that
matter.Yes,I did play with one step up one step down on the tx to make
certain I wasn't overloading or undermodulating.
So,I would like your comments on this.What exactly is the HiDynplus â„¢
compander system...how does it work ? After reading many posts and
having having experimented myself , this compander system is not so
great and seems to add artifacts that do more harm than good.
Anybody know what the difference is between their original HiDyn and
their '' improved '' HiDynplus ?Just trying to pinpoint a problem I
have.Thanks.

Are you sure it´s a "problem"? How often will you be recording a
dialogue while the character is going to dangle his keys in front of
the mic?
Seriously, while this test shows what a compander-system can do and
what not I think it is less relevant in practice.

Even if the system could deliver cristal clear key-dangling would it
be a good idea to have an actor say his lines while dangling his keys?
I guess even with a hardwired boom-mic you might end up in ADR if this
happened.

I wouldn´t worry too much about this test. It might show a few
differences between brands but in reality it might never need to prove
the key-dangling capabilities.

Since no one has responded I'll put down what I know. Given that we
are competitors, you may want to adjust the grain of salt size,
upward.

The HiDyn system has high frequency pre-emphasis both pre and post
compander. Total pre-emphasis can be as high as 30 dB. This gives an
excellent signal to noise ratio and removes a lot of compander hiss
(pre) and RF link noise (post). It does make the system sensitive to
strong, very high frequency transients. These are not evident in voice
reproduction with the exception of the softening of occasional strong
sibilants. Our emulation of this system on the 400 series shows the
same results though we spent a lot of time trying to make ours
"better". As I've said before, most design is a compromise and the
HiDyn system went for low noise and low gain cell hiss. The solution
is to stay away from jangling keys.
Best Regards,
Larry Fisher

All very good and valid points. There are indeed more things than just
keys.

More than just keys indeed...
I did a shoot with a dog trainer and a small jack russel
on a wooden ramp that took her up to chest height.
Her claws on the ramp were not to loud, and very natural as she
was in the shot. Sounded great with COS-11/SMa/411a system.
For curiosity, I switched to an analogue system and it
was very annoying to listen to. I wish I had recorded both
to have a strong example...

Dog toenails? I am continually amazed.
