Bi Amp Question

Milk_Steak · #1 11-07-2011, 08:37 PM

Ok so I have a GK1001 RB which has bi amp capabilities and I am currently using a carvin 1x18 and an eden 2x10. I used both cabs for the first time at practice today and was able to get a decent tone but theres one problem that might be pretty big. It seems like the same signal is getting sent to the 2x10 and the 1x18, this signal is very bass heavy and while the 1x18 can handle it if feel like im pushing the drivers in the 2x10 too hard and they might not be able to keep up. I dont want to blow my 2x10 so is there anyway i can make it so its not pushing as hard without compromising my sound.

apparently, the "biamping" of the 1001 is just between the speakers and the horn in specially wired GK cabs (so a way higher crossover point, just for the tweeter).

you're not gonna get a proper crossed-over split between the 18 and the 2x10, which should be more like 100-125Hz.

That amp won't work for what you are doing.

The Bi-amp part of this amp is made for GK speakers only.

It allows 50 watts to go to the tweeter of a GK speaker set up for Bi-amping with this amp.

The best you can do is full range. 4 ohms @ 540 watts.

ok well thats not a huge deal cuz im about to get rid of this amp anyway after a year i still cant dial in the tone on it im chasing, im thinking of moving to an eden head or maybe something else someone could suggest that would have good bi amping capabilties for the situation at hand?

please elaborate specifically on what you mean by "full range 4 ohms @ 540 watts" the whole electronic aspect to bass amps really escapes me

i dunno, that's a raging bass head!

maybe you should lose the weird 18/2x10 thing instead. a wall of 10s or a pair of 15s would kick butt under that amp.

There's no point in bi-amping a 1x18 and 2x10 as there's not enough difference in their bandwidths. You just need an amp with dual power amps with independent volume controls.

If you are talking about the 1001RB1 then that amp is 380 watts @ 8ohms and 540 watts @ 4ohms. When you plug in one 8ohm cabinet you get 380 watts and with 2 8ohm cabinets you get 540watts and sense that system is only going to run full range with your cabinets it will be full range, not crossed over.

so to maurice, do you have any decent amps in mind or know any amps with this kind of capability that seems alot simpler than all this bi amping. also what if i just ran these in a line like from amp to cab to cab, instead of how im doing it now which is amp to cabA from output A and amp to cabB from out B?

You can do that or, you can plug both cabs to the output that says 540watts only, on the back, same thing.

Sorry to post twice, I didn't put the quote the first time so, as to make sense, I posted again with the quote, sorry

o its all good man thanks for the help

The board does have an edit function for posts, a little clunky but with some practice you get used to it.
If you want to Bi-Amp the Carvin is nice, if you like G-K, the 800RB is the only Bi-amp head (with built in crossover) still in production. The 2000RB has this feature, the 2001RB has dual amps but the crossover went away I believe.

Milk_Steak · #16 11-07-2011, 09:35 PM

does eden have anything that would work particularly well with what im doing?

**B-string** · #17 11-07-2011, 09:39 PM

We'll have to wait for an Eden fan? Some of their amps I have liked but other models seem to make good doorstops IMHO/IME. Just not enough stability for me personally YMMV.

The 1001 is a really loud head..... too loud for me...... which is why I ended up with the 700rbII.

I really believe that if you understand how your input gain, the preamp gain, the master, and the boost all interact, you'll start find how to dial in the tones you're looking for.
