    It is driving 4 8 ohm speakers, no crossover, and on 1 channel only. The input was from a pioneer djm500 which was cranked up but the amp was only at 10 o clock. To be honest I'am not sure what bridging really means. The set up is simple. phono output from the pioneer going to the headphone jack inputs and then 2 speakers connected to each speaker output. Sorry if this doesnt help you much!

    Hi. Thanks a lot for your reply. I also use that as a rule of thumb when wiring up speakers. However the bass has been working for the last 6 months or so. I moved house, thought it sounded slightly bassy when I set it up. Was loud for about 4 hours on new years eve, with bass and then all of a sudden it just cut out. Is there a fuse just for the bass? or a safety feature that may have clipped ALL the bass? I'am still not sure why it pops now when I turn the amp off and the left red clip light flashes on. Help is appreciated as always!

    Hi. there is definately something different with the amp. I have unplugged all the speakers so that you dont hear the pop, but the red clip light still flashes on as if it is the amp that is producing the pop sound. There is still no bass with only 2 speakers connected. What could possibly cut the bass completely?

    What is your setup? Is this amp driving sub woofers, or what type/range of speakers?, through a crossover? What impedance is the speakers? (i.e. 8Ohm..) Are you running the amp bridged, or on one channel only, or have you got 4 speakers per channel?

    The clip light and pop are not serious, they are just effects of the power supply collapsing.

    Regards

sounds like you have either a blown speaker,dodgy lead, or a blown crossover, i would experiment with different leads and speakers to narrow this down, i had a similar problem with my worrior amp and i ended up replacing all wiring within speaker cabinet (manufacturer used very thin cables) and not had a problem since. the thicker cable the better the sound and less resistance equals less problems.
hope this helps

Sounds like you may have a phasing problem with the 4 speakers connected in series. This has the effect of cancelling the bass out. Check that you have them all wired as say "stripe" to negative terminal on the speaker. I use this as a rule of thumb to be sure there are never any phasing problems. they all(speaker boxes) need to be facing the same way for bass to propagate well. Check that you have bridging OFF and all settings to "stereo" SAny other settings you are not sure on, just ask me here :)

I have a Behringer nu4-6000 amp that I am trying to connect Peavey 215 speakers (2-1/4 inputs). How do you connect the 4-pole cable that is bi-amping from d Behringer speakon, 1/4 only uses 2 cables.


I can't give you a definite answer but I suspect the Peavey speakers with their four wires require a different sort of amplifier.to the conventional type.

You will be aware in lots of speaker enclosures are one or two drive units and a tweeter. Ensuring the right frequency of signal goes to the right speaker will be a filter or crossover which is also housed in the enclosure. This has been the common way to deliver a good sound forever.

There has been a fashion for delivering a good sound differently by placing the filter network or crossover in the pre-amp stages and then delivering the different frequency signals to two, three or more power amplifiers, each one designed to amplify a particular frequency range and in this way fewer compromises are made to the purity of the resulting sound. Each amplifier would have an output through a pair of wires destined for the drive unit is was designed for.

Two and three rack amplifiers have been a very popular way of delivering sound in cinemas, in particular a powerful bass. I haven't personally been involved with such an amplifier but I remember the magazine Wireless World publishing a series of articles about the system and the instructions for building one.

These are just my thoughts on the matter and your next step would be to examine the internal wiring of your speakers to be sure.

Why is there four plugs on the back of speakers?


With four plug you will have a jumper from on plug to the other. (e.g. Positive to positive and negative to negative.) This is for single connection (two wires.) If you use two connections (four wires) you take out the jumpers. the bottom pair is normally for the bass and the top for treble. This is to make the speakers clearer, and sound better. As for louder,? I don't know some people think it does some don't. With better clarity of sound, you do get the feeling of it being louder.

Want to run 2 subs of 1 amp ep 4,000 in bridge mode.


You can do that but your subs will have to be monsters or you will blow them out as bridged mode will drive 2400 watts RMS into 4 ohms. Many speakers are rated in peak or program power... these are FAKE specifications. with this amp in bridged mode each of two identical speakers would have to be rated at 2400 watts program or about 3600 watts peak each to survive... When rating speakers and amps ALWAYS compare RMS values... and for safety use an amp of 80% of the RMS rating of the connected speaker or speaker system.

We have a pmp6000 mixer hooked up to our ep 4000 and b1800 and b2520,it seems we can only hook up the amp to the mixer into either mono's 1 and 2 or the main 2 however not in main 1 with full...


MAKE SURE the cables you plug into 1/4 inch mains are TRS plugs, and not mono cables (TS). The main output 1/4 inch jacks are TRS balanced outputs and if you plug mono (TS) cables that shorts out the ring connector reducing the power by 6 Db. USE ONLY TRS balanced cables for interconnects !!!! Also read my tip on Fixya regarding PMP mixers. If you use 1/4 inch SPEAKER cables or adapters, if you short the SLEEVE of channel A output to ground you can pop the channel A amp. The TIP of channel B is the hot BUT the SLEEVE of channel A is the HOT. The ttip I posted explains why this is and it isn't mention in the Behringer documentation.

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.

Amp volume drop with flabby bass sound.


1) can happen if the speaker is dying - voice coil defective or magnet needs recharging. happens sometimes with low quality speakers. 
2) faulty pre-amp section can reduce overall gain resulting in lower output volume.
3) for old amps dry solders in pre-amp & power amp section can have the same effect.
4) faulty coupling and filter capacitors can severely effect frequency response too.

Bass sounds muddy and volume is minimum.


Hello mercedesman4,

Your setup sounds great. I had to settle for Blaupunkt in my Mercedes.

It sounds like the culprit is your enclosure. It's possible that by tweaking the settings, you could improve the sound somewhat, but having been used to the sound of a sealed enclosure, maybe not. Sealed enclosures tend to produce tighter, more accurate bass and have a flatter frequency response curve. They are also generally the enclosure of choice when looking for a SQ (sound quality) oriented setup.

Ported enclosures will produce louder bass than sealed enclosures, and maybe that's why some audio guys push them. They also allow the speaker to operate more efficiently, so you need less amp power for a given volume. Higher tuning on a ported box will get louder, but at the expense of sound quality. Lower tuning will still get louder than a sealed box, and the sound quality will be better than a box tuned higher, but still not as good as sealed. That's what I meant about tweaking the settings. You may see some improvement by setting the crossover lower, decreasing bass boost, or by turning the subsonic filter on/off. I'm no audiophile, but personally I've never been able to stand the sound of a ported enclosure, however it was tuned. Sealed just sounds better.

Hope this helps.
