Hi!

Anyone can recommend a pro audio quality wireless system from mixer to
PA system imput that is up to about 10 meters distance (no walls)?
I need one for a live events but the PA system is very high quality so I
would like the wireless system to be close as possible to studio quality
sound.
Thanks.

Pozdrav,
Zvonimir

Zaxcom or Lectrosonics digital.

10 meters...
$200~250/m could be enough to get something? :-)

I've tested my new AKG SO 40 / WMS 40: it's very good. Tx can work 10
hours with only a AAA battery and it can handle 300mV at min sensitivity. If
you can work at -10dBV=-8dBu (Tx in and Rx out) it could be a good & cheap
solution bringing with you only two notes...

Yes, dig the floor and put a wires. :-)

The PA system inputs are designed not to be easily overloaded by +20dBu
usual mixer outputs.

Ok, but I was saying that the Tx max handling level could be too low for
a mixer out (you should take signal from a mixer's -10dBV tape out or use a
14...20dB XLR attenuator on the main out) and the Rx level could be too low
for a PA amp.

There aren't really any "good & cheap" solutions for this.
If it is only 10m (30ft) and it is part of a PA system with
everything else wired, why bother? Running wireless over
such a short distance is way more trouble than it is worth.

Lectrosonics would be my first suggestion; we have used the Lectro sets
for delayed speaker stacks at outdoor concerts and they were okay.

Zaxcom also makes some stuff.

Shure makes some devices intended for IFB which can be pressed into
service to do the job. Sound quality isn't up to the Lectros but they
are okay for a lot of stuff.

Vega actually made some devices in the eighties that were intended for
this job, and SOME of them use the VHF-LO television band which is
totally unused right now. I wouldn't have recommended them so much,
but the ease of VHF-LO frequency coordination makes them worth looking
into again.

That's really the solution.

I work a festival where we run 70V lines for about two miles of total cable
run, in order to provide cuing speakers and to allow the people at the front
gate to hear that something is going on down on the main stage. I have
occasionally looked at an RF solution for this because paying out two miles
of cable from a backpack through nettles and thorns is not pleasant. Still,
I haven't found anything that has both the sound quality and the range
required.

If anyone has an old vacuum tube Marti transmitter kicking around, though,
especially if it's on the 160 MHz broadcast auxiliary band, I would be
very interested in it....

Yep! 200~250 x 10 = 2000~2500 dollars. It's very huge compared to the
10m he has to cover between two steady devices.

I guess I could get out of mixer with low enough signal but after the Rx
and before the system input I should amplify it so the TxRx combo have
to be very low noise.
Might be a good idea.

I guess he is looking something like Lectrosonics D4 or similar as I do.

Wiring localy around the band is OK but 10m wires across the room is
unacceptable since quite a luxury place. There is no way I can run wires
without crossing a guests path. :-(

Thank you all for replay and help.
I have some picture what is available on the market and the prices.

If it is "quite a luxury place", then Zaxcom or Lectro would seem
like the solution, then. Bring THEIR checkbook.

Or remodel and wire the place properly. That's what I am doing
in one of my monthly venues. Installing permanent mic and spkr
cables to make setup and strike ever so much easier (and faster
and no hassle with the guests, etc.)

What are the latency specs for these?

The manufacturers' websites likely publish the specs.

Most of the Lectro systems are straight FM, with no latency issues. They
do make a digital line, though, with some noticeable latency. Less than
the 30 mS that you're already introducing with a 10 meter run, though.

The Zaxcom systems seem to have more latency than the Lectros.

The PA system is well designed. However it is easier to move the
furniture than in-wall audio plug-ins.

VHF-LO is still used in a few US markets, so be careful. Last time I looked there were six
stations which chose to remain on (or move to) channel 2, and approx. 40 stations in total
for 2 through 6.

I don't think so. The stations that were on 2-6 still retain their
nominal channel numbers, but they have moved to UHF over
the air. We have two of them here in PDX. However some
stations that were on VHF-HI have returned to their original
channels (as have most of the stations here in PDX).

Errrr... sorry for my bad Englis... Are you saying that 10m wire have
30ms signal delay?

No, 10m of air has about 30 ms signal delay, for the acoustical sound in
air.

Not true. I had this discussion on a ham radio group who were
claiming that all their 6 meter/channel 2 issues were gone
forever, and I pointed that in a few markets, ch 2 was indeed
chosen by one of the locals for their final digital frequency.

I just checked MI and found WGVK 52.1 on 5, and WBKP 5.1 on 5
(one of those stations who had a temp UHF channel and went back
to their original analog channel after transition.

Wow. That's pretty boneheaded. Channel 2 is the best possible place to
be in the analogue world, and the worst possible place to be in the digital
world.

5 isn't such a great place to be, but it beats 2 hands down. The solar
maximum is coming in just a couple years and it promises to be a good one.

Not only skip, but power line noise (which is 10 times worse on
low band than high band) is a deal killer for digital.

According to the online FCC license records, indeed there are 800
low-power ( 1Kw) transmitters on Ch 2-6, mostly repeaters out in
rural areas. And most of those appear to be "flea-power" (10W)
and with HAAT (height above average terrain) of "0m". Repeaters
were exempt from the digital switch-over earlier this year.

But there are ~80 higher power stations still left in some areas. But
none of them are very big. The highest-power station is only 27KW,
Ch 2 in LasVegas. For some reason they call themselves "Ch. 3."

I downloaded the manual but can't find maximum signal I/O limits. RCA

Make an adjustable pad. Turn it down until it stops clipping. Then
turn it down a little more. Mark with a Sharpie.
