1.) Budget
This is the big one, since I don't think she's going to get any help
from the school and will be paying out of the drama club account. I
asked what kind of budget she's looking for (remember, she really has
no knowledge as far as ballpark cost or anything), and she said "oh, I
dunno... about $100 each."
2.) Brand
Obviously this has a certain amount of personal preference to it, but
I don't know much in terms of ordering of the popular brands as far as
quality, reputation, or cost goes. My educated guess would probably be
Shure and Sennheiser at the top, Azure and Audio Technica towards the
bottom, and Nady, Samson, AKG, and whatever others I can't remember
somewhere in the middle. Of course, I could be way off, so whatever
input I can get here is greatly appreciated.
2.) Omnidirectional or unidirectional?
I've read that an omni in the center of the forehead is the most
popular method, but since we need to have stage monitors so the kids
can hear the music being played from the CD I'm afraid I'll get
feedback with an omni. Thoughts/experiences?
4.) VHF or UHF?
5.) Could we purchase a single receiver that can handle multiple
channels, and maybe only one or two transmitter/microphone sets for
now, then add additional sets down the road? Could we then also save
on rental costs by only having to rent transmitter/mic sets that are
compatible with the receiver we own, and not have to rent the
receivers too?
6.) Area/boundary/choral mics?\
I’ll agree with pretty much everything Steve said, but I’ll give you the same advice that I give to all of my school clients: Unless you are using these things on a regular basis (at least 4 times a year, I’d say), it doesn’t make any sense to buy them and you’re much better off just renting them. I get the impression from what you said that you are only using these once, maybe twice a year. In that case, I wouldn’t recommend buying them. As Steve has already said, you will have to store them and maintain them, and by the time you would have “paid” for them in rentals, there’s a good chance that something will be lost or broken.
$100/week is perfectly reasonable for wireless, and I don’t think you’ll see any real significant savings by buying them, at least not without sacrificing quality in a major way.

All very good questions.
$500/channel is about the lowest you can go before it's not worth buying. I recommend the Sennheiser 100 series (Either G3 or the now outdated but just as good G2; you may be able to get a deal on used or unsold G2 gear ).

I would put Sennheiser and Lectrosonics (probably out of your price range) at the top, followed by Shure and Audio Technica in the mid range, and then everyone else in the bargain bin.

Omni, center of forehead (cable properly disguised in the hair...it's not that hard, I promise). Don't put mics in the monitors (which means your monitors should *not* come from the same output as your PA speakers).

UHF. VHF is typically fixed frequency (and the only good VHF I know of are Shure LX [discontinued] and Lectrosonics these days)

Each transmitter requires its own receiver. That said, some manufacturers make rack-mount receiver housings that contain more than one receiver (see, for instance, the Lectrosonics Venue receiver). Keep in mind that units like this contain more than one receiver module (one per transmitter). It's not physically possible to use one receiver with multiple transmitters.
Make sure you buy a system that is tunable over a decent range of frequencies (so systems like Sennheiser's FreePort and Shure PGX are out).

I don't think choral mics will help, and boundary mics will only help so much (depending on where your speakers are). I find that boundary mics only help with big chorus numbers, and only to give them the slightest boost when necessary. THey won't help with less than six or so actors, and with kids it's going to take a lot more.

Don't forget about antennas and antenna distribution if you are buying more than a few systems. In general, you will probably need one antenna distributor (really a bandpass filter, amplifier, and splitter in a box) for every four units, and another one to split out to those splitters. If you are buying more than four units you should probably ask the list or an RF professional for help anyway (both in terms of planning and the initial setup).
Also, depending on where you live, you need to make sure you buy units in the bandsplit with the most free frequencies. Sadly, there is not a very good way to verify this, although PWS's IAS program comes close (it costs money but there is a free demo available).

Got it. Just out of curiosity... what kinds of problems would we
experience with something like an Audio-Technica ATW-251L (Freeway 200
series, only $150 or so)? Not that I would even consider buying them
if it were me making the purchasing decision, given the repeated
advice not to spend any less than $450-500/channel for decent
equipment... but I'm not the one making the decision, so I'd like to
know what to expect if it goes that way.
> Omni, center of forehead (cable properly disguised in the hair...it's not that hard, I promise). Don't put mics in the monitors (which means your monitors should *not* come from the same output as your PA speakers).
For some reason I never made the connection that I can't get feedback
if there's no way for the signal to actually feedback (i.e. mic
channels not sent to the monitors, therefore they can't feedback into
themselves). I just use an aux output on the console for the monitors
and the only thing I put on that aux output is the CD player channel.
Is there a better/more proper method (still very much a newbie,
here ;-) )?

The main issue is you can only use three of these at once because they are fixed frequency and those are the only frequencies they come in (the VHF part is fine, and in fact, will not be a problem). Also, they may not hold up as well to abuse by actors. I can't speak to the actual radio front end in the receiver as I've never tested them, but I'd be leery of something in this price range knowing the cost of quality RF components.

Nope, that's the right method. :-)

Hmmm,
It seems to me that I learned some time ago that audio signals traveled
through metal cables near the
speed of light. So a 100 foot cable would induce a time delay of less than
one micro second in a 300 foot cable. That is not a significant time
difference. I do not know the time required to encode and decode signals
in digital snakes. I wonder if that would be a problem for monitors?
page daniel
I calculated that light travels 90 meters in 0.3 micro seconds. It would
take light 0.3 ms to travel 90 km. Now that is a lot of cable. Since
these are twisted pair, there would probably be some effect, but the
information available on the propagation of signals in coaxial cables would
not apply.
Latency in cables or in analog circuitry has never been a problem that I
know of.

Given that the serious RF types (think radio astronomers) are generally
not bothered by soldered joints, it seems unlikely that they are
noticeably non linear at almost DC [2]!
Ref digital snakes, often the biggest latencies come from the AD and DA
filtering (a few dozen samples in some cases), but remember that sound
only propagates at about 1 foot per ms, so you do need to keep things in
perspective.
Actually the gotcha with the AD and DA delays is when you have a second
path that does not use them, say analogue to and from a compressor on an
aux with the with both the return from the compressor and a direct
signal within the (digital) desk being summed... Unexpected (and
variable!) comb filtering....
Regards, Dan.
[1] Capacitive loading may sometimes be a problem, but latency is just
very unlikely to be an issue.
[2] Solder is frowned upon for joining waveguide at multi Ghz
frequencies, but even there the problem is simply attenuation, not
linearity.

Consider a cable with a velocity fact of, oh, .5. That means the
propagation
velocity is on the order of 100,000 miles PER SECOND. That means the
basic
latency of a 1,000 foot cable is on the order of 2 MILLIONTHS of a
second.
I have a hard time imagining ANY artist that has an issue with a delay
of 2
MILLIONTHS of a second. Let's put this into perspective: that 2
millionths
of a second delay is equivalent to the artist moving his head 0.024
inches away
from the monitor speakers.
Look at it this way: the signal travels down the wire at a rate of
around
500 MILLION feet per second, or a latency of 2 BILLIONTHS of a second
per
foot. That latency is about 500,000 times smaller than the equivalent
latency for a similar distance acoustically.
If you have an audibly detectable latency, and we're not talking
cables
stretching across the state, it's source is NOT in the cable.

Definitely use the RF splitters that are designed for the units.
(They'll forget to tell you that the power supplies have to be ordered
separately!)
Unless you use very good cable (no RG59/59/6), the cable will cause
almost as much loss as the air distance from the transmitter to the
receiver. So get the good stuff or don't bother.
You can use the supplied little stick antennae with the splitters and
get great performance so long as the distance is not too great. We
are running 8 receivers off of a pair of sticks and a pair of
splitters with no problems at all (and have used these along with
another 11 channel rig).

you are now in the position of helping the next generation of actors understand that they don't need vocals in the monitors.
Sent from my mobile
I don't know that I agree with a blanket statement of no vocals in the monitors.I'd hate to have to sing (especially harmonies) if I couldn't hear myself.
As a matter of practice, it is best to leave the vocals out of the monitors
as Steve has recommended. The major problem is simple physics. With wig
microphones feedback is a problem that cannot be overcome especially with
weak voices. Yes, this can be overcome with boom mics and I do shows
that insist on E6's to solve the problems of poor systems and weak voices.
Proper design requires that the stage volume be kept low to limit the pick
up from the monitors by the omni microphones that the other members of the
cast are wearing as well.
That all being said, I have seen ops give a struggling soloist a little
monitor for a few of his/her numbers successfully. I also so a show
(Tommy) in which the lead wore an IEM for the show and this caused the
experienced FOH operator no problems.
While I have plenty of IEM's, monitors, and E6 booms available, none of
these is first on my list of things to plan on using for most theatrical
productions.

Page is totally on the mark here. There are exceptions and places where you
will end up putting wireless lavs in the stage monitors, but they are
typical few and far between. Most days you simply are not going to get
enough gain before feedback out of a small lav in the hairline to get any
useable amount of vocal foldback anyway. Or if you do, you have to notch
the signal so much that it sounds like complete ****.
It's always better to fight the other issues that are causing a performer
not to hear themselves if at all possible. Too much orchestra in the
monitors or too much natural orchestra sound on stage are some typical
issues and of course what is great for one actor will be totally worthless
for another.
I can remember the first musical I engineered and mixed professionally.
(Aint' Misbehavin) It was a tech disaster. The actors insisted on getting
vocals in the monitors, the band is right on stage, we didn't really plan
our sound system with that in mind so we didn't really have speakers
appropriate for that task, and the designer on the show not only didn't know
squat about sound reinforcement, but he didn't put his foot down and work
with the actors about putting vocals in the monitor (or not putting them in
there) and he was also on his way out the door of the organization as well,
so even if he had put his foot down, he would have been dismissed since his
credibility was fairly low with the organization by that time.
So I wasted all kinds of time trying to notch this and cut that and move
speakers to new locations. Let's just say in the end it didn't help the
show much at all and the cast was generally unhappy, a few more so than
others. :-)
It was a real learning experience that's for sure.
I have often done things like putting vocals in monitors for people that are
trying to sing a duet and their partner is 50' away from them. That makes
sense and can work if you have the monitors separated out into multiple
feeds to allow for it. And I've done it successfully for a solo here and
there on some big numbers where the signer really needed help. I've also
done it shows like Altar Boyz where it's really just a pop concert anyway
and the cast is all on headsets. But in general I avoid it and if you have
any decent number of cast on stage with their mics open simultaneously I
doubt you would get enough gain to be of much use to the singers anyway,
except maybe to hear each other. Certainly not themselves.

A couple of years a go I agreed to supply wireless microphones for a
musical for a summer festival and offered to help train their backstage
personnel and be of assistance with the best implementation. There was a
designer listed as a part of the festival who had already left town when I
delivered the equipment, a musical director, that I never met, and a
professor of musical theater direction, who as far as I could tell never
had used wireless before. The board op was a part of the venue staff and
probably had never mixed a large musical before. It was a disaster, not
because I did not know what they were doing wrong, but because of my
advisory status. I had no ability to tell the FOH OP what to do and not to
do, nor did I really have a seat at the table with the directors.
The next year they had a better director, an intern to for a board OP and I
agreed to give them some help that they knew they needed only if I was
listed as the associate sound designer which put me into the loop. This
solved most of their problems as I gained control over the maladjusted
house sound system and the staff could see that the producers trusted my
technical abilities.
