Amp and speaker died on me. HELP!

Fellow low-end brothers,

Here's the thing:

I had a Warwick ProFet 5.2, a Warwick 4x10 (8ohm) and a Warwick 1x15 (8ohm).

I used to connect the 4x10 to the amp's speakon connection, and then used the cab's speakon output to connect to the 1x15.

Today I bought a Gallien Krueger 1001 RB-II.

I used the exact same connection. Amp(speakon)>>4x10>>1x15

Played one note. Boom. The amp goes kaput and smoke starts to come out of the bottom cab, the 1x15.

I simply couldn't believe, and even though I'm really pissed off, I'd like to know if I should be mad at myself for having done something wrong.

Can anyone help me understand what happened?

Greetings from a seriously sad bass player.

Thanks for your reply, RickenBoogie.

The GK has 2 speaker cable outputs and 2 speakon outputs.

I connected the 4x10 to one of the amp's speakon outputs and then connected the 1x15 to the 4x10, using the cab's speakon out.

Peace.

The Speakons, are they just normal 2 conductor cables?, or something else? I'm not a GK guy, but I gotta believe this all has to do with the whole GK "biamp" thing, which requires a special cable for use with GK cabs. Have you asked on any GK threads?, there's gotta be some knowledgable GK users here somewhere. Hope you get it sorted, the whole thing sounds like massive suckage.

Try the amp with no speakers connected, see if the power light turns blue without speakers. Could be the 115 decided it was time for a vacation (burned out), if it shorted the G-K would go into protect (blue light would go red and there would be no output).
If the amp won't come out of protect (power light stays red) without any speakers connected then the amp has a fault, get it exchanged or serviced. G-K can turn out high current and it may have been more than the 115 could take anymore. G-K amps can use a standard 2 conductor, 4 pin speakon. Not sure if you can use an old 2 pin speakon without problems? email [email protected] to find out for sure.

Thanks everyone!

I used a standard Warwick Speakon cable like this one: Invalid Link Removed

And another equal one to connect a cab to the other.

I will go back to the studio to check out the blue-light thing, B-String. But I never saw it red, so I wonder maybe the speakon out died, and the other one is still rocking.

More news to follow.

I tried the other speakon output, still no signal coming out.

Tried with a speaker cable. Nothing.

Tried it with no cab on it and the light remains blue, as it does also when a cab is connected.

All that comes out of it is a bassy hum. Should I replace the amp's fuse?

This really is ****ed up situation. :bawl:

Using a standard speaker cable into each cabinet, put a 9V battery across the tip and the sleeve. There should be a pop from the speaker cabinet. If no pop your cabinet is toast. Having smoke come out of a speaker cabinet is a good indication that the cabinet is blown.

A 4x10 and a 1x15 is not a good match. The 15 will always be working too hard to keep up with a 4x10.

If the pilot light is lit the fuse is OK. Most amps nowadays have just the a power line fuse installed.

Thanks for your feedback, Paul!

The 4x10 is working perfectly. I still have the Warwick amp, so I tried both cabs separatelly and only that one works.

So, if the fuse is OK and no sound is coming out of the amp.. What can be done besides sending it back to the store?

The speakon cable you are using may not be wired wrong but may have a stray wire crossing over to another terminal. This would never show up in another amp situation because those terminals would never see a connection on the other end. The GK may see them wired wrong and crossed the high and low amps output. I could be way off but it would be worth checking the connections on the speakon cables ends. Best of luck.
