Normally for my larger venues I use my main set up consisting of (2) Peavy SP5G speakers . I just picked up a pair of their light weight speakers (12") My question is this If I were to daisy chain the light weight speakers to the main 15" speakers ( 1 15" and 1 12" on each side) Would I get a FULLER sound for a large wedding I'm DJing or would I jeapordize the sound of the 15" speakers by daisy chaining them to the 12" ??? My thought was to point the 15" mains on the dance floor and angle the 12" towards the sides a little. Good idea? Bad Idea or other??

When adding multiple speakers, you will get more sound & it will actually sound louder. However you really should use the same speakers when adding. 2 different sets (especially of different size & driver structures) will need different eq'ing & while one may be able to handle the extra power - you will be dropping you load to 4 ohms, the other set may not be able to. You'd be better off getting a couple more of the SP-5's.

Depending upon how much headroom your amp has, you may lose some of that power hungry bass. You can go to mono and use one side of the amp for each set of speakers then adjust the parametric EQ for each set of speakers seperately, (after you adjust the graphic EQ to a middle of road adjustment), using the adjustments on your mixer's channel strip. You will still be at 4ohms, but you can adjust the EQs seperately.

I know that the idea of mono leaves a bad taste in some people's mouth but in a club inviorment you may find this to be desireable.
Think of it this way, when listening to stereo, you hear some instruments louder than others from each speaker. More keyboards on the right, more lead guitar on the left, for example. Stereo is great when you're at home sitting right between both speakers.
When you use mono, the sound from each speaker reinforces the sound comming from the others. When you're using stereo, each speaker simply does its own thing.

Lonnie: I was afraid thats what you would say , (4) matching speakers would be the ideal situation , It was I just bought the 12" for some lighter smaller gigs and was "curious" what would happen if I add them with my 15" for an upcoming wedding I have booked.

Kojac you have my curiousity peaked ..If I ran my amp in a MONO configuration (which always confuses me) and used one channel for the 15" (daisy chained) directed to the dance floor PUMPING ..could I hook the 12" (daisy chained) for the other channel angled into the "seating" area at less volume?,,Does that make sense??? Lon, I know you are familiar with my amp Peavey Pv1200
it does have 2 channels and a mono/stereo button ????

Your PV1200 is a stereo amp. This means that it is indeed a two channel amp. One channel is labeled right and the other is left. Going to mono is done at the mixer. If both the left and the right output from your player is going to one channel strip on your mixer you must have the panner adjusted straight up to the middle of the road position to have the sound come out to both speakers. This means that you are already running in mono.
You must have the right output from your player going to one channel strip and the left output from the player going to the another channel strip, with the panner that controls the right side adjusted all the way to the right and the panner that is on the channel strip that controls the left adjusted all the way to the left to get stereo sound from your speakers.
If you asign each output from your player its own channel strip you can then have the right channel come out of either the right speakers, or the left speakers, or both by adjusting the panner. The same goes for the strip that controls the left output from your player.
If you connect one set of speakers to left output on your amp and the other set of speakers to the right, each channel strip can send its signal to either set of speakers by adjusting the panner.

I'll try to simplify:
Connect the right output from your player to an open channel strip, and then connect the left output from your player to another open channel strip. Keep the right to the right and the left to the left. Now adjust the panner on both strips straight up to the middle of the road position. Connect one set of speakers to right output from your amp and the other set to the left output.
Now one channel strip will control the volume and the tone adjustments for one set of speakers and the other channel strip will control the other.

I know that it sounds hard, but it really isn't.

Good Luck!

I THINK I understand ... If I take the (R) out of my player to the (R) input on channel 10 on the mixer and the (L) out put of my player to the (L) input on channel 9 on the mixer ...Both channels panned at CENTER .
Now I take 1 of the main outs of the mixer to channel A INPUT of the AMP and the other main out of the mixer to the channel B input of the AMP...then I connect one SET of speakers to A channel and the other SET to the B channel ...I'LL GET MONO SOUND OUT OF EACH CONTROLED BY THE CHANNEL STRIP FADERS??????

You got it!

Using this "hook up" will I be getting a "mono " out of each side or a true stereo (left and right )

Which mixer are you using again? Something doesn't sound right.

Lonnie, it took me a couple of times reading it but what he's talking about would work for DJ only. Just running a CD player through a mixer.(I did something like it last weekend when I DJ'd for a friends wedding) For KJ you might be able to get it to work if the mixer has sub channels.

Using the Mackie DFX12

That's what I thought. OK,


This is a stereo setup with one set of speakers on channel A & the other set on channel B. Channel 9/10 on your mixer is a stereo input, the pan will act as a balance control from left to right, panning straight up is sending the the left signal to the left output, & the right signal to the right output - it won't combine them to a mono output.
If you really wanted a mono output from both channels, you would need to take the outputs of your player & connect to the LEFT channel inputs only (not the right, this will defeat the mono option) on channels 9/10 & 11/12 on your mixer. THEN pan straight up & this should yeild a mono output out of both the left & right output of the mixer. You'll be using 2 faders for the music insted of 1, but it will give you the mono results.

Again although you will have control over the volume of each set of speakers, the sound may sound radically different being you have 2 sets of mismatched speakers (makes/models & size). You may need to have an outboard eq between the mixer & amp to adjust each set individually.

This set up works just fine for KJing. The mics have thier own channel strips.

Lonnie,
With this set up you can turn off channel 10 and send the signal that is being sent to channel 9 to either side of the amp via the panner. The same goes for channel 10. If you turn off the gain going to channel 9 you can send the signal that is going to channel 10 to either side of the amp via the panner. If the panners on both channels are straight up, both of the signals will be sent to both sides of the amp. Mono. If channel 9's panner is turned all the way to the left, and channels 10's panner is turned all the way to the right then channel 9's signal goes to the left, and channel 10's signal goes to the right. Stereo.

Since one set of speakers is connected to one side of the amp, and the other set is connected to the other, the stereo imaging will be distorted due to the fact that each brand or model of speaker has differant voicings.

In mono, each set of speakers can be EQed by using the parametric EQ controls on its channel strip. You don't need an outboard EQ. If you wanted to run in stereo you would need to run speaker models A and B in paralle, but then you would lose the ability to EQ the differant models of speakers seperately.

With one set of speakers connected to one of the amp's input, and the other set to the other amp input, and the left output from the player to channel 9, and the right output from the player to channel 10 you can adjust the parametric EQs to each set of speakers seperately, as well as the gain.

Don't forget that although the panners act LIKE a balance control, they are not balance controls. If you were using only one channel strip for both the right and left outputs from the player, then the panner would be a balance control, however...
When you are using two seperate channel strips for each of the players outputs, you can send the right output's signal to the left, and the player's left output to the right. Something that a balance control can't do.

Since we've gone this far, why don't we jump into the twilight zone and look another advantage to assigning each of the player's outputs its own channel strip?

Let's start off with a matched set of speakers connected to the amp, and each of the player's outputs connected the its own channel strip.
If you play a disk that has a track that has a vocal guide MPXed onto it, (some mfrs call this an instructional track), you normally hear the guide vocal comming out of one side of your system only, (generally the left side), but since each output from the player is going to both sides of the amp, (with the panners set straight up), you will hear it comming out of both sides of the amp. to both speakers.

Now this is where things get cool.

If you can turn down the side that the guide vocal is on. This is a great option when you have an unsure singer. He or she can sing along with the guide vocal, and you can turn it down until it's all the way off when he or she gains confidence, and you can turn it back on whenever he or she gets weak.
Some of the "Original Footage" VCDs are studio versions. It's SO cool to have a newbie female singer sing along with Nancy Sinatra's "These Boots Are Made For Walking", (this is a studio version, just like you heard on the radio 20 yrs ago), and slowly make Nancy shut her mouth.

One final thought...
If you connect the output from a sound processer to an open chanel strip, instead of sending it back into the mixer via an EFX return, you will be able to adjust its parametric EQ on that strip. You will also have the option of having it's gain controled by its strips gain conrol exclusivly or you can, (via the pre/post button), fade down from where you have adjusted it to at each of the channel strips that have a send going to it by either turning down that strip, (which tursn down the whole channel), or by turning down that strips EFX send, (which will leave that strips dry signal going to the main mix).

I never claim to be the best...
I yam what I yam,
I do the best that I can...

Do you even know this mixer???



Channel 9 & 10 (left AND right) are combined to one fader. 1 fader controls both channels SO if you pan 1 you'll lose the other entirely - like a balance control. Same with channels 11 & 12, combined to one fader. This mixer is designed with 2 stereo channels. Channels 9/10 & 11/12.
To get a mono sound out of these, you can't use the right channels - in this case channels 10 & 12. This is why he would need to use channels 9 & 11 (the left channels) of the mixer panned straight up. This will send a mono signal from channel 9 & channel 11 to both the left & right main outputs of the mixer. The mic channels obviously need to be panned straight up for a mono send - for both channels anyway.

Lonnie,
I didn't know that this was the case with Jamkaraoke's mixer.
The concept remains the same though.
I have a Mackie 1202 VLZ pro, 4 mic channels, and 8 stereo line level channels, (5 through 12).
Obviously DFX12 users would have to read my posts knowing that where I say channel 10, they should use channel 11.

Thanks for the clarification.

Kojak

Kudos to all that contributed to this thread... I learned from it immensely...
Always had troubles placing speakers in bigger clubs ..Was using stereo..I run a Mackie Dfx12 and changed L to mono 9/10, R to mono 11/12 pans middle..
Now I run the 2efx on one channel at unity and the other channel - way down... efx back in aux1 return fader up more and bal effects with faders...
Actually think I improved over all effects noticeably..

Question .. (without starting new thread) will be getting the Bbe 362 maximizer Any ideas where or how to hook it up? Thinking about changing mixer again (if something aint doin what I want I got the case off) and inserting between the the Eq and main faders out And do Effects first ??? Thanks Ollie

Well normally the BBE would be the last link between your mixer & amp.
You have an eq, so it would go mixer, eq, bbe to amp. With the BBE working, you probably won't need to use as much eq'ing. I would flat line the eq first, engage the BBE & see how it sounds - you may not even need the eq. If you do, do minimum adjustments, you aren't going to need much.

Thanks to all who offered their expertise.. Saturday was the wedding I was concerned about having enough "speaker coverage" I was all set to hook up (4) speakers as suggested ...When I go to the venue ..it was about 1/3 the size I imagined it to be ( Normally I would visit the venue before the actual gig to get an idea of the setup ..but time and distance didn't allow me to do this ) Anyway seeing the size of the room and the (2) flights of stairs I had to carry the equipment up I decided just to go with my normal 2 speaker stereo setup ...And a good thing because 30 minutes into the dance set I was told to turn it down because the ceiling donwstairs was shaking and the band down there couldn't hear themselves ..
Thanks Again guys !..Learned something new and thats always a good thing
