ok so i set up my ns7fx and i have a PR10 peavey item which i thought was a speaker. im not sure what im doing. all i want to do is practice with a speaker and my headphones before i think about getting better speakers. can someone help please. here is what i got http://www.bestbuy.com/site/Peavey+-+PR+Series+10%22+2-Way+Professional+Loudspeaker+(Each)/7840161.p?id=1205538058534&skuId=7840161&st=peavey&cp=1&lp=1. i would preferably want to purchase a speaker from bestbuy since that is the main store within my access.

I'm assuming you don't have an amplifier so that's why it doesn't work for you . Do you only have one speaker? If so you might want to get another one so you have a stereo monitor mix. In terms of an amp for your equipment, either a QSC GX5 or Crown XLS2000 would work fine. I'd have a look on ebay and see what you can get second hand. In regards to wether it is a speaker or not, yes it is. There are 2 forms of speakers; active and passive. Active contains in built amplification whereas passive - like what you have - requires an external amp.

The PR10's aren't powered, so you would need an amplifier to connect to

NS7FX -----> Amplifier ------> Peavey PR10

If you don't want to get an amplifier, I think the cheapest and best option since you are just going to be practicing at home is this:

It depends on the connections on the amplifier you choose. Pick out an amp before you buy cables. You'll most likely need XLR cables.

The Crown has XLR ins and Speakon outs. What connections does your speaker have?

I'm not sure that you're understanding the basics yet. Let's step back and take a look at how a sound system works (and realize that this is a gross oversimplification for teaching purposes):

1) A sound reinforcement system represents sound as an electrical signal. That signal has a few important properties, if you remember back to high school physics, but one we're worried about right now is amplitude. The amplitude, or strength, of an electrical signal in a sound system is what represents how loud the sound is going to be when a loudspeaker changes it from electricity back to sound.

2) The point of using a sound reinforcement system is to make the sound louder. Sound is recorded at very, very tiny amplitudes because there really isn't much energy in sound. Furthermore, loudspeakers are very inefficient - your Peavey PR10 has an efficiency of maybe 5%. That means that the electrical signal put into the speaker has to be 20 times bigger than the level the sound was recorded just to get back to the starting point!

3) That's why you need an amplifier. An amplifier takes the signal in a sound system and uses electricity from the wall outlets to make it stronger. Your mixer simply can't put out the amount of signal that is needed to drive a loudspeaker.

Today, you can find mixers with built in amplifiers or loudspeakers with built in amplifiers. You have neither, so you need an amplifier.

Finding out how big your amplifier needs to be is a bit complex, and lots of people will try to sell you a bigger amplifier than you need because it sounds cool and makes them more money. 300 Watts at 8 Ohms is the maximum I'd use for your speaker. Here's a couple amps that would fit the bill:

http://www.bestbuy.com/site/Peavey+-+IPR+DSP+1600+1600W+2-Ch.+Power+Amplifier/9356403.p?id=1218095840217&skuId=9356403

The cables you have listed are also incorrect. Here's how you would hook up your system:

And here are links to the kinds of cable you'd need:

OK. I really feel like you should do your research on this first but I will help you out real quick.
Return that speaker. Get store credit for it or let it go back on your Best Buy card.
Tell the salesman you want this http://www.bestbuy.com/site/M-Audio+-+10%22+250-Watt+Active+Speaker/3177101.p?id=1218382973197&skuId=3177101&st=gsr%2010&cp=1&lp=1 Seems to have gotten a good review even though I have never heard it myself. Tell the salesperson that you need them to pricematch with an online retailer that is an authorized retailer. There is a very popular pro sound and stage retailer that sells them for only $99.99. This speaker is active and includes a built in amplifier. Get two if you can afford em
Then get this http://www.bestbuy.com/site/Rokinon+-+Audio+Cable/4498861.p?id=1218479659820&skuId=4498861&st=xlr&cp=1&lp=11
One per speaker. You will be fine. However, read your instruction manuals. They will help you out

Keep in mind those speakers use 1/4" not speakon

True... That's what I get for not reading the spec sheet.

But seriously, Speakon has been pretty much standard for twenty years now. Why would any manufacturer still use 1/4" for speaker level signals?

almost all of the low quality passive cabs i've come accross all use 1/4" jacks. Don't ask me why but they do..

I bet 1/4" jacks are cheaper.

Far cheaper. In quantities of 1,000, you can get em as el cheapo as a few cents each for the really crap ones that a lot of low end companies put in cabinets.

Speakons get as low as a couple bucks (at most) each in large quantities.

Even before I went to all Speakon in late 2006, I immediately dropped in open frame TS jacks on my first set of PA cabinets when I unboxed them, since they have better contact and plug retention than 'stock' on the MCM 12" 2-way speakers I used to own.. Also beefed up the wiring and stuffed the cabs with Polyfil for a cleaner, tighter sound.

I have since sold them and I'm sure they're still out there somewhere around Colorado Springs poundin' the night away in some small restaurant or bar...

ok so here is the back of my ns7fx. i got m-audio av 40 speakers from best buy since this is the only place i can get instruments from. i also have Hosa technology insert cable 1/4" in TRS to dual RCA cable. So here are my series of questions. i will also post up some pictures to give out a visual of whats going on.

1. when i plugged it in i plugged it on the either left or right input then plugged the rca into the master. with both red and white plugged in it is making a weird echo sound is this suppose to happen? one way i solved this was to only plug in the white cord on the left master side. is this weird that i only have one plugged in and one hanging out? it seems to work fine.

2. So what is the purpose of the booth and master outputs? since im just trying to here out of both i just need one more of these same cords so i can hear out of my right one right? do i need both master and booth to practice for a beginner?

3. i found krk speakers at best buy, is this better than my m-audio ac 40 speakers.
website: http://www.bestbuy.com/site/KRK+-+Rokit+5+G2+5%22+45W+2-Way+Studio+Monitor+Speaker+(Each)/9444498.p?id=1218120547426&skuId=9444498&st=krk%20speakers&cp=1&lp=9

4. if i get the krk what wires will i need to get for the ns7fx?

sorry for all the questions. i just want to get this down so i can not worry about this and get the practicing. thanks everyone btw for the help and responses from previous threads and posts.

Left output goes to the left speaker, right output goes to the right speaker. You need a separate cable for each.

Master out is for the house speakers, booth out is for booth monitors.

Why is Best Buy the only place you can purchase equipment? You can get a prepaid cash card at Wal-Mart that will let you buy online from Full Compass, B&H, or any other reputable online retailer.

Where are you plugging in the insert cable? That is not something you need at all...

You want an RCA male to RCA male cable to go from the master outputs on the mixer to the inputs on the loudspeakers.

I'm not too current on Studio Monitors, but I have heard that the KRKs are pretty good.

Agreed on everything but I would use the XLR cables instead of the RCA if he indeed does go for the KRK.
