Hi Matthias,
Please don't apologize for complaining. Something is very wrong with
your system (especially if the wireless boom is noisy) that needs to
be fixed. My guess is, that if it is happening with all four of your
transmitters and receivers that it is a setup problem and not a faulty
unit (that would seem more likely if only one of the receivers was
exhibiting this behavior). How did you line up your receivers? How
did you set your Cooper board from the -20 tone outputted from the
receivers? My line up process is -20 from the receivers = 0 on the
Cameo which equals -20 on the Deva (same levels, just different
scales). I'm not sure what kind of headroom the Cooper board has, so
I don't know if you want to set -20 from the receiver to -20 on the
input of the board. Try setting it at -10 or -8 like the old Nagra
days
Post by MattThe receiver outputs a line level that goes in my CS 208. I have
levelled the preamps with the tone from the RX4900. These inputs are
dead silence. If I plug my boom hardwired into the mixer there is no
hiss or something at all.
If I do a A-B comparison hardwired boom and trx boom (with ambient UMP
48V) the wireless boom is way too noisy.
I can't figure this out without seeing your set up. On my system the
wireless boom and hardwired mics are indistinguishable. The only time
there is noticable noise is when I am using the Audio Ltd HX Schoeps
transmitter. With that unit I hear both hiss and companding. My
Zaxcom wireless with a Schoeps (or Sennheiser) are as quiet as a
hardwired mic. If you are getting noticable noise that is not self
noise of the mic than something is wrong. Where are you located?
Have you spoken to a dealer or to Zaxcom? WIll you be anywhere near
New York? You are welcome to come see (and hear) my system.
That might be ok with a
Post by Mattstreet scene but not with an internal quiet room dialogue scene.
I have the limiter off. And I can check the display on the RX4900 that
becomes checkered if a signal is to high. So that is not the reason
for the compander-effect. But Larry had found the reason for that one
- as mentioned in a previous statement.
Maybe it all has to do with us (Europeans) using frequencies between
790-830 MHz whereas you (US) are using a much lower channel / freq?
I'm in the 680 range. The frequency shouldn't make any difference.
There is a different mode for European use than for US use because the
European equivilent of the FCC does not allow the same bandwidth that
is allowed in the US. I am not familiar with the European mode,
though I had thought the differences were minimal. You might want to
try switching to US mode to see if that makes any difference though it
sounds like a call to your dealer or Zaxcom is in order.
I just re-read the thread. Any chance it is the switching issue that
Glen Trew mentioned? Did you email Glenn Sanders from Zaxcom your
phone number? Have you spoken? I know he is off to Europe for 2-3
weeks. Where are you located? Perhaps you can arrange a personal
visit. I'd love to hear the solution.
