Help! How Do I Run Two Ampeg B100-R's at Once?

Aladinsane1969 · #1 01-28-2011, 09:04 PM

Do I have to use an ABY box, or is there another way?

Thanks!

You could try the line out of one to the -15dB in of the other. All of the EQ settings of the first one will affect the second one but you would still have control the master on both. Just be careful with the gain on the second one.

Thanks, there's a guy on here who posted a picture of one stacked on another, so I was hoping there's a way to do it. I have one, I'm thinking thinking of picking up another, and I just found a good deal on one. I just want to make sure I won't harm the second one in the process.

So, since the signal from the first one--EQ and all--would be running directly into the second one, I'd need to make sure that the EQ settings on the second one are exactly the same as the first, correct?

A right angle cable will do the trick if you want to do the line out thing, even with the amps stacked, but personally I like the ABY option

No, the EQ on the second one would be set flat using the line out method.

So all set on "0"? [Sorry if these are stupid questions]

Yes, set the EQ to zero on the second one and make sure you aren't using any kind of boost switches.

This amp doesn't have an efx return, so you have to feed it into the guitar input on the bottom amp. Setting the EQ to 0 on the bottom amp should do the trick. This way, any change in the top EQ affects the bottom amp sound as well. With an ABY, you would have to adjust both EQ sections identically. Use the line out of the second amp to feed the PA.

Here is the manual:

Cool, thanks for the help, guys!

I use a pedal tuner to split my signal when I run the B-100R with a B-15. I've experimented sending a line out from one to the input of another, but running them on a split signal seems to work the best.

ABY here

Hmm... So I'd run a line from the "out" of the tuner to one amp and from the "bypass" of the tuner to another? (I have a Boss TU-2.)

That would work but you wouldn't be able to mute and tune as the bypass is always on. Either get a different tuner pedal or an ABY box.

Right. Lol, so it basically looks like I'm back to square one with the ABY box....

Sure, but I think it's worth $ 100.00 or so to double the B100 goodness.

I gigged my B100R pair a few times running the firsts combos pre-out into the seconds input, sounded good but I found stacking the preamps/tone knobs to complicated to make quick adjustments at the gig.

Your Boss tuner pedal would work. Only one its outputs doesn't mute but you could simply connect that one to your top combo and manually turn its volume down for silent tuning. (I didn't own one back then so I dont know if i woulda had any noise/hum issues)

I also gigged my pair of B100R's a few times splitting with a Morely ABY pedal. I never experienced any serious noise/hum issues but several guys here have reported having this problem with either using the Morley or the Y-cable splitter method.

To solve noise/hum issues, a few guys here have recommend either plugging one amp in through one of these:

Or splitting your signal through this model ABY pedal:

No idea on the Boss tuner. I use a Fender pedal tuner - and it has two outputs, only one of which is shut "off" when the tuner is engaged. So when I do tune - one of the amps will still get signal.

Another vote for the ABY. I am typically a Boss believer, but the Morley ABY switcher is very nice. Most will tell you that the Morley stuff is built to outlive your great-grandchildren. I was using it to run two amps(as you are looking to do). It's an infallible method, won't cost much, and you have the option of setting your EQ's different on each amp if you wish.
