What type of connector are you looking for?

RCA, TRS (1/4" stereo), TS (1/4" mono) or Speakon?

Probably the simplest is Parts Express (

Like Sparge said it's most likely coming from the cable itself.  Somewhere along the cable should be a little box with at least 2 coaxial connections (in/out)  There should also be a screw that has a single strand wire on it running to either the ground rod outside the house or a cold water line (assuming it's copper.)  It won't work (as well) with the hot water line.

Good luck

Depending on your budget I would suggest Electro-Voice's EVID-4.2 or 6.2

They're weather resistant and sound great.  4.2s will run you in the neighborhood of $375 per PAIR and the 6.2s will put you back $600 per PAIR.

Just my humble opinion (I install them in a lot of churches with no regrets from anyone.)

No doubt you'll get what you pay for.

Guitar Center carries these at around $300 for the set.  I can almost guarantee you'll be replacing it soon.

If you can hold off and put aside a little more $ then I would recommend something in line with a Matrix-200 ( for around $400 or even better a B-52 Matrix-600 ( for around $700.

Both are quite capable considering their size and carry well for personal backyard use.

Try sitting the PJ no the floor under the screen pointed towards the golfer and bouncing the image off a mirror angled back up at the screen.

DJ's will do this to avoid the projector from being out on the dance floor.
8  Backyard Theater discussions / Receiver specific / Re: Does anyone know how to operate a compressor? on: November 21, 2013, 12:29:20 pm
Close but not quite.

A compressor is just that.  It compresses a signal.  The threshold is where the compressor kicks in, attack is how aggressively it compresses the signal and release is how long it holds the compression after the signal drops below the threshold level.

It never really limits the upper end (volume) that would be the job of a limiter.

You could compare it to a large someone trying to push open and walk through a door (threshold) and smaller someone trying to push the door closed (attack), the harder the second person tries to push the door closed the more the attack.  The smaller person has no chance of preventing the larger from passing through but gives it the ole college try.  After first person has come and gone the second stands there holding the door closed just in case the offending person tries to sneak back in right away.

Compression should be used very sparingly, it's primarily used in the audio world to protect your speakers in the event someone drops a microphone or a drummer whacks a mic with a stick or someone just being stupid decides to scream into a mic that was set up for softer vocals.

All this protection comes with a price in that it starts distorting the signal.  Compress something enough and it will sound like heII.

Behringer also makes a compressor / limiter combo unit which adds the limiting function that does close the door on the signal and prevents it from going any higher.  It also adds another level of complexity (and audio distortion) to what should be a simple task.

In all honesty you probably don't need the thing.

First off the license issue is part of my std. contract and should be part of yours as well.

Second off - I turn them down if they refuse to get one.

I always insist on seeing the Swank agreement so if they decide to play games and lie to me I have the option to cancel the gig right there on the spot which ultimately ends in the forfeiture of the reservation fee as well as the contracted payment (you did get paid in advance didn't you?)  This too is part of the contract.

Now if they want to get pissy you simply call the sheriff / police and let them give the client the bad news.  Doesn't make for a happy client but then again THEY broke the law and not you.  It's tantamount to receiving stolen goods in the laws eye, not something you or your business needs.

Best advice would be to run away...

seriously, consider your average movie theater (which is about 1/2 the size of the room you're describing) and realize they've probably got 2 dozen speakers along the walls and another array behind the screen along with the bus size sub woofer.  That's what you're talking about to reproduce 5.1 music videos.

If at all possible just utilize a stereo playback device.  Pretty much any older DVD player will play any 5.1 disc and give you a stereo output.  Just because it's there doesn't mean you HAVE to use it.

Sorry for the long delay in responding.

First off with the room being 175' deep you're going to really want to consider some delay speakers.  In order for the back of house to hear at any volume you're going to kill the poor soul sitting in the front row (unless you're using line/source array)  Not going to bore you with the math (too lazy on my part if truth be told) but the jist is you loose 6dB every time you double the distance from the speaker, you gain 3dB every time you double the wattage so trying to throw sound a long way from a point source speaker (std speaker on a stick - multiples are the same) makes for a very uncomfortable front row seating.

Adding a second (or third) set of speakers along the walls will allow you to keep the volume level down and not deafen someone.  It is possible to omit a delay unit but the sound tends to be garbled due to sound arriving from several sources at different times.

If this is a one off production and you don't have the cash go for it but if this is a long term install then you'll want to invest in a delay unit (dbx Driverack will do this along with several others - note that a digital delay/reverb unit is not the same animal.)

As for myself I'd be using several sets of 12" speakers (3 pairs) and driving each with 300-500 watts, not because I'm looking to blow the doors off the building but because I want the cleanest sound with plenty of room left over to eliminate the chance of distortion.

My speaker/amps of choice are ElectroVoice Sx300's driven by QSC GX5's.  This combo has been the mainstay of my sound & lighting rental business for many years without a single failure.

Now for the Peavey / Behringer units.  As was previously noted Peavey units are built like tanks - heavy, heavy, heavy but  will get the job done.  Behringer on the other hand... I personally loath them.  Built to the lowest possible standard and still be able to label them a speaker (or any other electronic device they mfg.)  Same goes for Harbinger, Kustom and a dozen other dirt cheap manufacturers.

Buy quality once, buy cheap over and over and over...

A lot is going to depend on the efficiency of your speakers and movie content.

What speakers and what movie?

Let's start there first and then we can better help.

$$$ and more $$$

Aluminum is going to cost a small fortune I'm afraid and just as easily damaged (bent/kinked/etc) and then doubly expensive to repair.

Just my 2 cents

I'd go with both top and bottom
