Daisy-chaining a GK MB800 to a GK MB500

[BigEarl]

Can this be done?

I have an Accugroove Tri-115L and an Epifani UL2-410, I would like to power each individually putting the MB800 on the 8 ohm on the 115 (for 500 watts) and the MB500 on the 4 ohm 410 (for 500 watts) making a rather formidible 1000 watt monster.

I know I can buy a splitter and send an individual line into each off my bass, but is there a way to hook them together ...without it being a kluge?

^ DONE. Let the room shaking begin!
I have done this the exact same way from the Fusion 550's effects send to the 800RB's effects return. Who needs the PA?

But wouldn't both speakers then be connected to the 500?

Nope. The effects send is a preamp out. The effects return interrupts the preamp to power amp signal chain, anything that comes from the tip and sleeve of the cable will feed the power amp.

Then that's exactly what I will do. Now I am awaiting the old "don't mix speaker size/type" flame war!

Thanks all!

DON'T MIX SPEAKER SIZES!!!!

Feel relieved?

Note: When I chained the 800RB from the Fusion I ran A 412 from the Fusion and 4 15" from the 800RB

Holy moly, B, that's some serious cone acreage, bro. Must've moved massive air!

We played on a wooden show trailer. Everybody got a massage, PA took a rest from bass duty and six florescent tubes fell from the overhead lights.

It was FUN! Our ears rang for a day and a half though.

A few questions (of anybody):

With the effects loops - of both heads - being used in this manner, wouldn't that severely limit your options for using effects? Like, requiring you to plug into your effects chain first, then feeding into the input jack of the MB800 (in this case)? Are there any other options for using effects?

With this configuration...

...would that not effectively put the preamp section of the MB800 in control of the power amp sections of both heads? In which case, one still would connect the MB800 directly to the Accugroove, and the MB500 directly to the Epifani - and operate both cabs via the MB800 controls?

Just clarifying...

If you plug your pedals into the first amp's effects in then there shouldn't be a problem. I don't use pedals so it wouldn't affect me.

Actually, this kind of set up bypasses one of the pitfalls of mixing cabs. You get to power them separately which means you can send less to the 15 if need be.

You can have differing levels of volume but the EQ is coming from the first amp in the chain so you can't EQ each cab differently.

Thank goodness someone got that done.................

^^^ this - and power both amps form the same AC power outlet

Don't care how old you get, every once in a while you still get stupid ? I guess it was an Iron Butterfly concert from decades ago (three day hearing loss) that inspired that lapse in good judgement

[Joe Louvar]

this is correct (slaved) - you need a splitter to use both amp EQs

Or MB800's effects send to an eq before the effects return of the MB500. BTW both masters and the Boost on the MB500 will still be active.

If you're talking about stomp box effects pedals, they should go in the main input anyway. The loop is generally line level, so for rack effects.
