GK 1001 rb speaker overload, is my guess

Hey, I have had my GK for only a few years. I bought it used, it sounded great a that point. guy how sold it to me claimed that this unit was send to GK and has the upgrado of the 1001 RBII circuitry... I am runing a cort 5 string soap bar bartolini active pick-up thru a boss DS2>line 6 bass floor POD. on a 1X15 (ashdown) speaker cab. it sounded prety good to me. the lows were realy low and clear on the extra low button... one day the thing made my speaker go crazy with distortion, so I took out the distortion pedal from my signal and still had the distortion. replace the battery on my bass and still with the distortion. at the end of the day I was resignated to have a burn out speaker.. a few days later I hoked it up again and sounded normal. turn on my distortion and still good. a few minutes later, no distortion been played, and boom speakr is full of distortion again. cheked the speaker impedance and was good at 6.9 ohms. So i tried it whith a Hartke 4x10 cab and it did the same thing. started out good then went crazy with distorted signal to the speakers.

I ask around with some guys who install car stereos and they told me it's probably a faluty volume knob. But I don't know exactly how to change this. and try again. is normal weld good enough? Do I need a certain temp on the welder to do this? has anyone heard anything similar, before I start messing up my amp?

Please help. I HAVE NO MORE MONEY FOR A NEW AMP!!!

cheers to all

This problem is not likely to be a volume control problem. There is a transistor inside that is failing (getting noisy) when heated up. If you have no experience with amp repairs, do not attempt this as it is not simple to locate the defective part. Continued use in this condition can cause problems with the speakers. Please have this serviced by a repair shop with experience with GK gear.

Crackling from bass combo when I hit low notes


I'm afraid it sounds as though the speaker has been overloaded. The replacement for this will, unfortunately, be a new driver (the speaker unit itself).

I have a set of 901 IV with no equializer, I am


As far as I know, any equalizer will work. There is a guy on here that might know more about them, but I never had the Bose equalizer and I have Bose speakers for 35 years. The guy at the electronic store back then sold us a little equalizer at first, we graduated from that a long time ago, and now on the 3rd or 4th one. No problem, works great, sounds better than ever. Hope this helps.

My speaker set up boston acoustics ba7500 will'nt


The Guys at Boston Acoustics helped me get my speakers to work. The Boston BA7500 speakers are coaxial digital speakers so you need a digital output on your sound card. Analog will NOT work. My new HP Pavilion has a Realtek sound card with a digitial RCA plug output. I had to go to Amazon and get a male RCA to 1/8" Stereo Mini Female adapter plug. I just pluged it in and configured my sound card to 16 bit 48 khz output to the RCA output and everything works great. The speakers sound better then ever, great for 10 year old speakers! They sound better then anything I have seen avalable today. The guys at Boston were the only guys that helped with getting this to work! Thanks again to them and Amazon has every type of adapter plug you may need. Good luck.

37" Philips LCD no sound.


Maybe the antenna that you are using is not picking up sound from the channels. It could also be the cable. If it makes a humming noise, it means that the speakers are getting electric current and that they SHOULD be okay. It also could be your tuner. Maybe check it all out at some tech place like best buy. Those guys can help

2.1 creative speakers.


Speakers need to be used much often.If they are left without using they might get affected with dust and charge storage.It happens with generally every brand.
The solution could be either servicing it or generally using it very regularly.

Overloading


hi mate, ive had the same problem before with this amp. i bought it new aout 6 years ago and bought another new one about 1 year ago, new, for £70!

on the first amp there was a problem with the surround sound aspect, it kept overloading when turned up even a fraction, it would tick 4 times and power off. Eventually the surround sound stopped working all together and whenever selected made a VERY VERY loud hissing/crashing noise through all my speakers, blowing one of them, SO BE VERY CAREFULL.

when that happened i assumed was broken so bought another one, and had same overload trouble when i got a new speaker package.

Im pretty dam sure it was the ohmage ratings being different on 2 of the surround sound speakers that srewed the 1st one, so id suggest you check theyre all ok, as well as the speaker watt-age.

what are the specs on all your speakers (ohms and watts RMS)??

do you listen to LOUD music through the 5.1 option??

hope this helps, if all else fails buy a new one mate, theyre so cheap. go into panasonic shops and see if they have any left.
