2 Speakers on Sticks Stereotype

I have a wedding reception coming up in a nice and large hotel ballroom. Based on the number of guests, I was already planning on using a 4500 watt system with 1360 watts of lights. After seeing the size of the room, I recommended the client upgrade to a 7900 watt system. They loved the idea and paid the fee.

When I toured the venue I noticed they had a power drop lying in the service hallway close to where I would be setup. I immediately got excited because I knew if I could use it, my setup time would be fast and I wouldn't have to worry about power later in the reception. I wouldn't spend time figuring out which outlets are on separate circuits.

I had the client sign a service agreement amendment indicating they would provision the power drop. Today I get a call from the venue basically asking if I was sure I needed it because normally they don't use it for wedding receptions. Normally they charge $200 for the PD, but would waive it for this (good) customer. I could bring my distro, but using the venue's solution seemed less complicated and convenient.

I seem to get this type of reaction all the time and it surprises me each time it happens. I've only been a mobile DJ for five years but am starting to realize DJ's here have been stereotyped as using 2 speakers and lights on sticks and less than 40 amps of power. If you ask for more than two circuits, it's almost taboo. Another thing that baffles me is the people selling the power drop can never provide a spec sheet for it and I have to always wait for "maintenance" to call me back.

Here is what I'm using for this party..

(1) QSC PLX 3002 10A
(2) QSC PLX 3402 24A
1260 watts Can Lights 10A
Playback & Processing Gear 6A
------------
~50A Total


I was going to break it up conservatively:

(3) One circuit for each amp (all in the same rack)
(1) Circuit for playback gear (table top)
(1) Circuit for lights
---------------------
(5) Circuits Total



Anyone have similar experiences?

And you need a power drop for that?

Just run to 3 different circuits and balance your load.

I run 3, PLX 3002's, 4 Martins, 4 Moving Heads, all processing, my computer, my lcd projectors.... all on 3 circuits and the power is monitored and I never come close to tripping a breaker.

Just my opinion.

Hi Scott,

Thanks for your reply. I guess technically I don't need a power drop. I could spend several minutes finding three circuits and hope nothing else was on them. I could also get away with three solid 20A 120 VAC circuits. However if they were three 20A 110VAC circuits I would be pretty nervous. In this case a drop was lying just a few feet from where I would be setup and seemed the most logical and convenient to use. I was just wondering if any other DJ's get raised eyebrows from venue managers when they make similar requests.

(1) QSC PLX 3002 10A
(2) QSC PLX 3402 24A

At half volume, they draw a 1/10th of that, making it pretty easy to put three 3402's on two 15 amp circuits. Unless you are running big subs, bridging, or clipping them, PLX 3402's typicaly never pull more then 5-amps each in 8-ohm stereo mode.

I have tripped a 30-amp with one 3402 - but it was driving 8 inefficent subs and a live keyboardist suddenly cranked his submixer. I origionaly had 2 amps driving the subs, but we had to pull one to cover another need.

Hi Brian I agree with you. I'm running the 3002 in stereo @ 8 ohms into two JBL SRX715s. I'm running each of the 3402s @ 4ohms bridged mono. Each 3402 drives a JBL SRX728s. I know they pull some juice because the voltage meters on the 20A Furman power conditioners bounce when the tunes are bumpin'. I don't run the amps into clipping, but close to it occasionally if Ok'd by the client.

I get that all the time. The ole "Well we have never had a problem before" line. Most times those are the venues I have problems in.

If the voltage meters are dipping, that means you do not have sufficient gauge of wire providing your feed lines.

For the 3 amps and lights listed, it could be run conservatively on 2 circuts, and very safely on 3.

Now, most, (not all) wedding clients do NOT want piles and piles of equipment there on their wedding day. Most are more than satisfied with smaller systems. In your case, obviously it's a different story. Although, you have not stated the actual size of the room or number of guests that you are using THAT much power for.

When dealing with large systems and large power requirements, there are extra hassles you have to deal with. It's part of the business.

Hi bjojade,

I agree with you in regards to the cause of the voltage meter dropping. I wish some of the facilities were wired better. But the truth is some circuits have long runs to the service panel. My audio gear is all ran through 20 amp conditioners with short 12 gauge cords.

The system being using for this reception is very discrete and fits well at a reception in my opinion. All guests will see is a playback console case and laptop on the DJ table, two speakers on stands, and a light tree. If they walk around, they may discover the two dual 18" sub cabinets and amp rack on the floor.

Amusing post for me, because we get the opposite reaction in my area. A lot of DJs here bring a sound system much larger and much more potent than necessary (we're talking two double 18 subs and 4 large horn-loaded tops for weddings that seat 100 guests in an intimate setting), so when I walk in with two JBL Eon G2-10s and a tiny Yorkville sub into a place I'm new to playing at, the staff look at me funny and wonder "So where's the rest of it?" and "You sure you don't need us to run you a line from the breaker?"

Thanks for the laugh :D

I do mostly weddings of about 150 people or so. I run both my sound and lights off of one 20 amp circuit all the time. I've never tripped a 20 amp circuit breaker. Here's my typical setup.

I have never understood why some people think more is better. I have never had a problem with power or tripping any breakers. I sometimes run everything out of one outlet.

2 15 in tops with amp
2 powered mackie 1500 subs
light tree with 9 different lighting effects
dual cd player

Took me awhile at home, To get everything evened. I've done my share of tripping breaker's, However now I've got everything down pat, Aslong as I don't add anything else to the mix! HaHa.
Only take's me 5 outlet's (breaker's) to run my rig. I also put 15 amp power strip's on lighting, And booth power, So if I would happen to trip one, I can reset it from the booth. :D

That's one thing I like about the Crown CE-4000, I can run two of them off the same outlet. Believe they both come in at 7.1 amp's each at peek power? I'd have to look at the book again.

While many suscribe to the less is more theory, I too prefer good clean power that's not being shared with anything else. I'll always take a good clean source whenever possible...and while many talk of amps only drawing very little power...perhaps...but most doesn't truly bring in a well balanced system capable of good dynamic peaks...short term power draw is many times what an average is...again, give me all the power I can have...

Bass can draw 10 times or more the power of the mid/hi's...and this does NOT overpower anyone...it merely provides a good well balanced sound.

I suspect these halls have never hosted large proms, where "more is more" comes into play.....

My giant setup had video, two Crown Powerbase 3 amps, one QSC PLX 3402 amp, two EV Eliminator subs, two Soundtech LT5 speakers using the biamp input for subs, and six tops. That was before the lights...

Hmmmm... those flat panels are looking pretty good.....

I had this happen this weekend. I was doing a pretty big room in Detroit ......(Southfield GRRRR wife is reading over my shoulder and correcting me) and I told the guy I was bringing my Mackie system. I show up with 2 Mackie 450's and my 1801 sub and he couldn't stand it. He said there is no way it will fill the room. So he called and rented more sound equipment and they came out and set it all up and buy the time they got there I was ready to do my tests. I was playing some music and he walked over and said wow that is pretty loud. I agreed and he asked if I would turn it down and not use the other speakers "to much". I just giggled and then used the other speakers at a lower volume so that there wouldn't be as much fatigue.

This was one of the largest events I have gotten to do yet and I will post pics soon.

8 mini macs
4 accu spots
BIG DAMN mirror ball
Huge truss
Video camera
Huge screen with projector


It looks small on here but trust me it was pretty big.

Stereotype?

probably because its true.. :) 90% of my weddings have under 300 people, I'm pretty sure most DJ's would say the same thing..

My setup has no problem running with two 15 amp ccts..

Any hall that houses more then 300 people usually (in my area) has a 50 amp plug close to stage..

of all the weddings that I have done I have only needed a distro box twice.. (school and corporate is another story though)
