Los Angeles Area Mega Meet, Saturday July 11th - Page 7

Usually, a power drop means that they will 'drop' from 3 phase 220 or 480 (The building's main supply) down to single phase 110. Then provide at least two independent 20 amp circuits with it. That ought to do it... LOL

Thank you for putting this together. How do we get our donation to you?
Just contact IPodPJ to confirm there is an open space.

Nice to see someone else in the film industry that also lives in the South Bay. Welcome!

I'm in Redondo, maybe we should all have a Sub - Mini Meet!

The manual usually says. Sometimes it is printed on the back of the device.

Merely hundreds? You're going to have to do better than that if you want to help us.

Seriously that would make things quite simple.

Cool, more south bay'ers. I'm pretty slammed right now, but maybe over the summer we can do a micro meet.

As in near Redondo beach? Plenty of seafood. Nice!

Thanks. I guess they were wrong when they told me a cable came down. It is on standby if we need it.

Each of the two rooms has their own circuit, so multiply Mike1127's figure times 2. The Power drop would bring it up from 15 amps to 20 amps. Even at the discounted rate they gave me, it will still be $200. So we need to figure out if we do need this and if so, how we all pay for it. But I don't think we will, so let's start figuring out everyone's own power draw with the gear they are bringing.

Mine is about 100W for my audio equipment and how much does my Dell and monitor use? LOL. Let's say 500W to be safe.

We should already have enough money to cover it though. However, so far I have only received the contributions from about half of the attendees. So I ask you to please send them in as soon as you can since I will be billed for the power drop as well as the room fees (which was already charged) very soon. Most people contributed $15, a few contributed $20. So if we average out $15 over 25 attendees (hopefully the full 35 will show up) it comes to $375. $233 was the room charge so we will still be about $60 off. And that's assuming the power drop fee covers both of the rooms.

To the person who asked about contributions, all details should be in the first post, but here is my PayPal address again: pjnuckingfuts@yahoo.com

A desktop computer, even with a high end video card(I assume you're not using crossfire or SLI), should draw no more than 350W at full load and should draw about 170W on idle.

A 24" LCD monitor should draw about 60W give or take.

VA=W

Therefore, using your 100 watts as example...

V=110, W=100, A=X

100/110 = .91 Amps
There's a little bit extra lost in resistance and power factor, but not a lot.

So, if each 'station' draws about an amp, a rough guess would be that you could have 15-18 'stations' running at full power at the same time. So, including the other two 15 amp circuits, I'm guessing that should be more than plenty.
I'm sure everyone won't mind kicking down another $5 or so...


P.S., They may actually 'drop' it from the ceiling, it just depends on where it's fed from, so you weren't necessarily 'wrong' LOL

Well, I'm sure we will have plenty once we get the other two 15 amp circuits, but I'm not sure about your calculations. Are you including any safety margin? I would not plan on putting more than 10 amps through a 15 amp circuit. 7.5 amps would be better. We don't know how the power may spike, or what the breaker's actual performance is. (Nothing behaves exactly as rated.)

But I think you have more experience with these matters than me, so I will defer to your judgment about safety margin.

100 watts is probably a realistic average per-station, except if someone brings a computer. With equipment + computer, PJ's load is WAY over 100 watts even in the most optimistic estimate. However, as long as not many people bring computers we should be okay.

Oh, absolutely, this is the roughest of estimates... Remember though that it's assuming all connections are running at their maximum, all at the same time, which is very unlikely. (Full power sustained square waves on each amp, simultaneously or something like that...) sustained load is usually a small fraction of peak power draw.
I don't work in the 'consumer' end, though, so the best thing to do would be to call the hotel engineering department, and ask their electrician... They can give a much closer idea than me.

I don't think this is true for headphone equipment and sources. My CDP draws about 30 watts constantly. It doesn't matter what I'm playing through it. My HP amp draws nearly constant wattage as well (I'm not sure what that is). Just to run the tubes and the PS takes a certain wattage. There is no significant "peak load" for a headphone amp because it is only putting miliwatts into the headphones.

So I think the load from HP equipment and sources is nearly constant. If you CDP says it draws 40 watts, then that's what it draws.

Is anyone going to bring a soldering iron to the meet? I ask as I would be very appreciative if someone with the know how could cut my HD800 cable and solder on some XLR connectors.

I'd provide the connectors.

I had a friend once with a remote control plane. Ya know with the box and controls and antenna. He went to this place to fly them but wasn't really good enough to take them off so he would have other people do it. One day he asked someone who he saw was good at flying there at the strip to take it off for him. It took off, went up stalled and plowed into the ground disintegrating. The guy handed him the controls and walked away.

Case in point, that is nice cable to be dissecting and having someone with a golden soldering iron get their hands on. I learned the hard way with ham radio mods.
