The genious i bought these beasts from unplugged the 4 ohlm speakers off the bgw gtm 750 power amp on board on both pairs and forgot where they go..
there are 5-6 places to plug the red and black wires from speakers to the power amp.
the only logical places are right next to the giant transformer!
any ideas or schematics that show how and where the red/black spkr wires connect My ohlm meter shows 2-3 @116 volt 2@ 60 and 2 grounds im assuming ( no current)
WoW ! Simply remarkable!
I called the company that bought-out BGW in 2003.
"American Amplifiers Inc." California
I talked to Angie who was the best ! she transfered me over to
the Master Tech/Engineer (Larry)
I explained to Larry my problem. He pulled the schematics and we
inspected EACH input /output off the binding posts / large transformer.
21 in all 7 on each side and 7 on top. Larry asked me to identify each colored
wire attached. He discovered the wireing was all backwards and NOT
where they were supposed to be! Disaster in the making! We literally
rewired the hole power grid over my cell phone ! (1 HOUR), double and triple checked each
imput. The subs are back up and thumping hard. (they would be dead without AAI)
AMERICAN AMPLIFIER TECH. INC. IS THE MOST PROFESSIONAL, KIND HEARTED,PEOPLE,READY TO HELP ANY BGW OR AATI CLIENTS I HAVE EVER EVERDELT WITH IN MY (25) YEARS AS A PRO ROAD MUSICIAN!
PLEASE DO BUSINESS with this AWESOME COMPANY :)

Zombie post, I know... But, I have a solution for this. Remove the power amp unit from the rear of the sub cabinet. Remove the sheetmetal shield, noting the 4 allen screws on the side. Th daughterboard that the 4 screws thread into is a filter for the power amp's output, and is the last circuit that the powered signal goes through before hitting the speaker. If you inspect the solder joints, you will likely find that there are several which are bad. they will look cracked, potentially discolored in the crack. Resolder the joints, making sure to use good solder, and fill the joint. The most likely culprits are the 4 joints belonging to the 2 blade connectors which attach the daughter board to the larger board (which is the actual amplifier component). Again, sorry for digging this problem up from the grave, but when I searched for a solution earlier, this was one of the only posts that resembled my issues, and it never got a good solution.
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.
You didn't mention what brand powered mixer you have, HOWEVER MOST powered mixers also have a line level monitor and main output jacks. These are almost always 1/4 inch jacks. In any case you should be using BALANCED lines to the powered speakers using either XLR or TRS connectors on the ends. Please tell us what powered mixer you have so we can give you better answer regarding which connections to use. IF for some reason your mixer does NOT have line level outputs, you can use a high level Direct Box to condition the powered outputs to be sent to the powered speakers..
Also make sure ALL your interconnected equipment is powered by the same receptacle or source to avoid damaging due to ground bounce on utility lines and circuits. This often means running an extension cord from the stage where the powered speakers are along with a snake of the audio cables.
You haven't mentioned what model and manufacturer the mixer is. I will have to guess and say that the monitor out on the board isn't providing signal to the powered monitor or the monitor out on your board is powered and is now damaged by plugging a powered monitor into it. Carefully reread your manual and determine if the monitor out on your mixer is powered or line level. Reread also and make sure that the signal you are monitoring is assigned to monitor out, levelled correctly etc. If you find that the monitor out is passive (line level) try hooking it up to an external power amp and speaker. A guitar amp will do for testing purposes. Start with a low input volume on the amp. Also make sure that if it is passive to use a shielded cable from monitor out to input. If your board has powered monitor outs you can use a speaker cable from monitor out to speaker input (non powered monitor speaker).
Please read a tip I just posted regarding a hazard of the Speakon to 1/4 inch cables when used with these PMP mixers.
If you are using your main speakers as stereo, then you will need either powered monitor speakers OR an additional seperate amp for them. The mon outputs on the mixer are LINE LEVEL and are not driven by a power amp. Use TRS (balanced) interconnect cables from these to POWERED monitor speakers.
You can parallel your two mains providing the parallel impedance is 4 ohms or greater (two 8 ohms in parallel at most). The the monitor speakers can be paralleled and the switch set to Main/Mon so that one side of the power amp drives the mains and the other drives the monitors.
To prevent damage to the mixer, make sure all speaker leads are secure before powering the system. Run the speaker leads through the handles of the speakers to prevent inadvertent unplugging due to personell tripping over cables.
This unit will put out around 400 Watts a side. PLENTY !
If you want a sub, either get a powered one or an amp for it and run off the MON output.
CAUTION: NEVER permit the speaker cable to be removed or interrupted whilc power is on... you will arc out the rear most amp in the unit... I know... I fix them... There si a bit of weak insulation that can arc through on a circuit board.
If you ever have a fuse blow, DO NOT replace it, you will do further damage inside the unit... take it for service.
You don't specify which model Phonic mixer in question.
Is it a powered mixer ? And are you plugging your speakers into the speaker outputs ? If it's not a powered mixer and you're plugging speakers into the Line Outputs, you're not using a power amplifier between the line outputs and your speakers - this won't work.
If it is a powered mixer and you are plugging speakers into the speaker output connectors and still getting little or no sound, check your speaker cables and the speakers themselves by plugging them into known good amps.
