I need to send audio from an iMac G4 to a phone line for a system we
have set up at my high school. I'm wondering what kind of adaptors or
equipment we will need? We have a stereo mini jack connector, multiple
USB and Firewire connectors. We do not require stereo audio as our
system can only handle mono.

Could someone please help us?

You need a coupling device, speaker or phone patch. You could use a regular phone.
It seems like you could do it with a computers built in modem if the hardware and programming are right.

Cordless phones often have a phone jack for mic and headset.
You would need a resistive attenuator, fairly simple, and there would be
no ground loops if the handset was off the charger.

Is there an easier way, the "phone system" is mainly the PA system
(which we need to accompony/replace the audio being sent through the
CCTV system we have set up. We would like to do it as cheaply, easily,
and quickly as possible. Although it will not be done quickly as we
need to get the room we're using wired for the PA system. So if anyone
has any ideas, please respond.

All you need to do is convert to RCA or XLR connector to the PA. Best
use a audio transformer "ground loop isolator" like fron Radio Shack to avoid
hum. You can probably buy all the stuff at Radio Shack.

A "phone system" and a "PA system" are completely
different animals. If you can't precisely define your
question, you'll never get useful answers.

If it is a conventional "PA system" it likely has one or
more inputs that you can connected your computer
into directly. Just use a cable with a matching
connector at each end.

You will need to describe in more detail exactly what
kind of equipment you are connecting to. Make and
model numbers, what types of connectors, any labels
on the equipment, etc. etc. etc.

To my knowledge, we'll only be able to have a phone jack for the PA
system. We do have RCA outputs from the computer right now, which
connects to a television modulator via a minijack-to-RCA connector and
an Apple Mini-VGA -to-Composite video adaptor. But the original
question stands, how to [easily, cheaply] connect minijack (or RCA)
probably through a phone. I personally don't know much about the
school's systems and getting a technician in takes a while...

Please define what you mean by "phone"?

Do you mean the telephone system (the one that rings when
you call the number and you hold the handset to your ear?
How does a telephone have ANYTHING to do with sending
audio around the presmises?

Or are you talking about a "1/4-inch phone jack" in a public-
address system amplifier?

I still don't have a clue what you are asking about and likely
won't reply to subsequent messages again unless you offer
something to work with. Else, we're both wasting our time.

[[email protected]]

Our PA system goes over a special telephone line. Don't ask me how
they have it set up, as I don't know and can't really find out without
a technician coming in.

If you can't describe it, it is unlikely we can help you from
this distance. You'll have to wait for your technician.

The "THAT Corporation" used to make a device that did just this, but
it seems that now they only sell chips. Maybe I missed it - try your
own search.

Must have been some other company with a similar name.
http://www.thatcorp.com/ has never been in any other business
that I've ever seen. We have been waiting for their chips for
years. For a long time, they were essentially vapor-ware.

The OP is sufficiently unclear about his requirements and
situation that it seems unlikely that we can help him.

Maybe you should explain the difference, and where the phone line fits into
the picture?

Your answer makes no sense. First you say "No, we're not."
then you immediately say exactly the opposite.

Richard, not all audio is music. They could be planning to play
spoken word, or test tones, or white/pink noise. They could even
be planning to play prerecorded fire alarm signals.

What he wants to do simply requires a line driver. A faculty
advisor or the school's AV technician would help him out, if he
asked. I suspect that they want to hack into the school's system,
which is not a smart thing to do.

No, we're not trying to hack into anything. And yes, by audio I mean
we do not plan on playing any music. The teacher who's room we use
doesn't know anything about it. The principal and the IT guy have the
same stance. Our PA system uses telephones. In our office, they have
phones that someone would press "Talk" or whatever, then talk into it
and press "Cancel" when they're done. These phones require special
phone lines into the room. The room we use is in the back-right area
of the building on the second floor while the office is in the front
on the right, first floor. The full story of what we want to do is:
We're doing "video announcements" or a newscast, we wish to broadcast
the audio into the several rooms that do not have projectors or
televisions such as the gymnasium. Currently, we use a television
modulator from Pico Macom (I think it's the PCM55) set to channel
nine. Also, that I know of, my school doesn't have an A/V technician.

Not clear why music vs. not music has any importance?
Audio is audio. Or are we missing something here?

There are dozens (maybe hundreds?) of systems that
work something like that. If you can't actually tell us the
make and model numbers (at the very least) it is unlikely
that anybody here could help you. Do they have any of
the documentation (operation, installation, service manuals)
for the school sound system in the office?

The room we use is in the back-right area
of the building on the second floor while the office is in the front

So is there a way for the Principal (etc.) to make an
announcement to "all rooms"? Can you do that from
the room you are in? Usually those systems allow an
"all call" only from the master station (the Principal's
office, etc.)

If you come back here only every 30 days to reply,
it seems more likely that you will graduate and go
to college before you resolve your qustion.
