How to hook up bass cabinets to my powered mixer board

I have Inter-m pc 1635 powered 16 channel mixer board that our band uses and i can not figure out the best way to hook up my sub woofers which is my bass cabinets to the pa board. They do not have a crossover in them. I have a power amp i use to rub my 4 monitors with but i jist can not figure out the best way to hook up the sub woofers. I use to come out of the back of the main speaker cabinets {which all my speaker cabs are peavey} and go into my subs with but I could not get a loud sound out of them. I was told by another person to use my E.Q to power my subs with but when i do that the main volumne slider knobs will not control the sound level of the cabinets. The manual I have says not to use the E>Q unless necessary so i dont use it. Like i said this is a 16 channel powered mixer board with the model being Inter-m pc 1635. there also is a pc 1225 that is just like my powered mixer but it only has 12 channels. could you please help me figure out what jacks i need to use to run a power amp out of and to power up the bass cabinets up seperate from the main speaker cabinets.
thank you

    Do you have a power amp for the subs?

I would recommend using a separate active crossover such as the Peavey 23XO and a separate amp for your subs.

SOURCE: I need to know step by step how to hook up my

ok, first thing will be the effects processor. look for the "aux sends" output jacks near the bottom center of the rear panel. run a 1/4 inch instrument cable from "aux send" 3 out into the input on the vocal processor, and run another from aux 4, if the effects processor has 2 inputs. then, from the vocal processors output, run 1/4 inch cables back into the "stereo returns" on the mixer, (located on the rear panel on the bottom, extreme left) 2 outputs per input, since its making stereo effects. so, if you ran just send 3 into the processor, you should have a left and right return instrument cables into the mixer for "stereo return" 3 (left and right). if your processor has 2 imputs, and you are using both "aux send" 3 and 4, then you will have to have a pair of cables going to each "stereo return" for 3 & 4. -to apply effects to a microphone(s), you would adjust the individual aux send levels for each channel you want to have effects, and you would have to ensure that the master aux sends and returns are also turned up..

ok, the snake is simple, each xlr (3 prong mic) connector on the snake is labeled, so, just plug each xlr jack into the corresponding channel on the board, and plug the first 2 1/4 inch ends of the snake into the "C/R out balanced" outputs on the board, located on the rear panel, up and to the left a bit.

at the stage end of the snake, ues a 1/4 inch instrument cable to copnnect the first 2 1/4 inch jacks on the snake to the left and right inputs of the crossover. then, from the crossover, connect the sub power amp to the "low" stereo outputs of the crossover with instrument cables, and connect the main speakers amp to the "high" stereo outputs of the crossover with instrument cables. if its an adjustable corssover, you will want to have it crossed over somewhere about 80-120 hz to allow only the lowest frequencies to the subs.

now, from the amps to the speakers, we ane going to have to use heavier 12-14 gague SPEAKER CABLES, instead of light gague instrument cables. hook the subs up to the stereo speaker outs of the sub amp with speaker cables, and do the same for the main speakers.

The lamp is an "1156" lamp... replace with that part number. Here :

Or you can find it at auto parts store.

LIKELY the polyfuse device is ALSO gone... Probably similar to this one (1.1 amp, trip 2.2 amp):

SOURCE: I have a Behringer PMP6000 Board. It is connected

Since all your speakers are passive, indeed there is a problem like what you describe. This is because with the same amount of signal from the board's speakers outputs, the 2520 can't play the same amount of audio with the PASW18. I don't know what other equipment is available (if any) so let me give you some suggestions.
1. Connect in parallel the 2520s at one of the board's output and do the same with the PASW18 at the other channel output. Doing this you will be able to handle one channel (e.g. left) for the main speakers level and the other channel (right) for the sub speakers level. No stereo playback, so set all the inputs to mono.
2. Use another separate amplifier to drive the subs. You have to provide signal to the amp from any LINE LEVEL OUTPUT from the board (using mono is a very good idea since low frequencies have no stereo separation and in this case you could use a single channel amplifier for both subs, parallel connection)

If there is available more equipment post me back in details to give you guide lines.
In case of a problem or clarification or further details needed (connection diagram e.t.c.), don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, accept my solution.

Thanks and regards

You can, but I would not suggest it. Depending upon the input design of the powered sub, the highs might not get filtered out. Many subs assume that they are only receiving the lows. You are better off using a crossover between the mixer and the amp for highs and the powered sub for the lows. Please note that the crossover will give you much more control over the sound quality.

My band plugs into the input channels on the SX2442FX mixer, which we then hook up to the PMP2000 to use as a PA. Since the SX2442FX is not a "Powered" Mixer, I figured that we should be going...


Either way will work, however your friend's method probably would be slightly better since it goes through less stages within the PMP2000. The "left and right power amp inputs" are the INPUTS to the power amp in the PMP2000 and hence are the best places to connect the mixer if using the PMP2000 as only a power amp. Note doing this will LIKELY disconnect any other input to the PMP2000 from the power amps in it... that is all the preamps in the PMP2000. DO USE TRS cables!!! and power both units from the same receptacle to avoid ground bounce.

I have a peavey 1220 powered mixer and I'm trying to hook up to two sp15's top's and 2 18; peavey subs for my band and I can't get the bass seperated so it's out of my tops


Hi. The mixer puts out a full range mix, the solution is in your speaker setup.

Many subs have a built in crossover that splits the signal for the tops. Check your sub specs or manual. If your subs have this, run your output signal to them first and then link them to the tops from the special daisychain socket.

If they don't have one, you can install a passive crossover to your subs or buy an external crossover unit.

The last (and not very good) option is to fake a crossover with the desk's stereo EQ. Connect the subs to the left or right channel and the tops to the other and use the EQ to remove the bass from the tops and vice versa, pan everything dead center. Obviously this sacrifices your stereo sound and isn't brilliant.

What is the best way to run a Bass thrue the mixer , Mike the Amp or directley thrue the mixer, we had problems with a clear sound?


The easiest way is to take the line out from the bass amp and connect it to the line in socket of the mixer ( not the XLR Mic in ). This will give a clean and flat sound which you will have to customize using the Mixer tone control and not the bass amp controls.

When we are trying to get a reasonable level of sound for vocals before it gets loud enough to be able to hear clearly with the band playing it starts to clip at the speakers now we are only using this set...


Proper level setting of the mixer is important. HOWEVER if the clipping is occuring at the speakers the only possible problem MIGHT be that you have a supersonic feedback that is saturating the speakers above your hearing range, Be sure you don't boost the highs too much with the EQ as this can cause the feedback that you can't hear. Also make sure that you power the speakers from the SAME receptacle as the mixer, even if it means running an extension cord to bring power to the mixer. This is to avoid a low frequency hum and common mode distortion/damage. A low frequency hum could cause the clipping.
It would be a good idea to get a sound meter to check the sound level. You should be able to reach 85 Db from this system without clipping. If you need more than that, you MAY need more speakers if the band instruments are too loud. Also if the band has amps that get into the vocal microphones that adds to the clipping level... make sure the mics don't "hear" the band instruments. Make sure your speakers are toward the audience from the mics to avoid the supersonic feedback problem. If the vocalists can't hear themselves with that configuration you need to set up seperate stage monitors.

There are some pretty good videos on YouTube about proper mixer level setup.

If I'am powering 2 Peavey 4 ohm bass binns, then linking, from the base bins, 2 15" 4ohm cabs, should my selector switch be in main L and R mode ,or Bridge mode for maxium output and performance,...


You CANNOT power 4 total 4 ohm speakers from this unit without special configuration. The lowest you can go is 4 ohms per side, which would be one 4 ohm cabinet per side. You would have to do a series parallel arrangement with the resources you have... two Peavey's in series and that combination in parallel with two 15's in series...
This is a VERY unsafe configuration with this mixer. ALSO please read my tip on here in regard to PMP mixer grounding hazard of the A channel when using Speakon to 1/4 inch cables.

Frankly, forget about maximum performance unless you want to risk blowing your mixer...

If I were you, I would put the two 15's in SERIES as 8 ohms on one of the channels and the Peavey's in SERIES as 8 ohms on the other channel.

You would be well to heed this warning as I have repaired a bunch of these units. Be careful of any poor speaker connections as there is an insulation breakdown problem in the power amp circuit board if a speaker becomes intermittent. If something fails DO NOT replace the pwer fuse as you will do more damage.

You will need at least a 24 channel mixer to give you spare channels. You also need an active crossover and a snake. The advice you need is too much to include here so I am including some links:http://mixonline.com/live/FixIts/, http://en.wikipedia.org/wiki/Live_sound_mixing, http://mixinglivesound.com/blog/tag/outdoor-concerts/,http://mixinglivesound.com/blog/, and http://www.scribd.com/doc/11435651/Beginners-Guide-to-Mixing-Sound. You may need more monitors than you are planning on and you might consider in ear monitoring.

Can you directly hook a sr16 to a peavey bass speaker cabinet using the output mono on the sr16 to send or retrn on the cabinet?


You can, however a bass speaker cabinet will NOT handle the higher pitch sounds needed for cymbals and snares, etc. You would connect it to the return AND doing so would DISABLE the other inputs of the bass speaker cabinet.

If you want both a guitar and drum machine into the cabinet, you need at least a small mixer or a speaker cabinet that can take two channels input simultaneously.

Plugging into the "return" of the cabinet DISCONNECTS the power amp from the preamp section in the cabinet.

Have you considered any of the Behringer cabinets that are recommended companion pieces for this mixer. For more expensive gear have a look at JBL cabinets. The EON series is good. Have a look at what other bands you know are using and listen to their sound to see if its what you like.

No Volume oe sound coming out of speakers


try connecting speakers to another sound source or if you have access to a ohm meter, check impedance of speakers, should measure 4~8 ohms.
