Daisy chain question

I'm up on matching ohms and such but I'm wondering about using the daisy chain set up for bass cabs.

I usually run my AD200B into my 410 and 115 using two speaker cables connected to the two 4 ohm outputs. What I'd like to try is taking advantage of the speakon connectors on the back of the cabinets and daisy chain the two.

Question:?:- Do I connect the single speaker cable to one of the 4 ohm outputs on the amp? Each cab is, of course, 8 ohms.

Any comments on if this changes anything with the sound or volume? I'll be using my speakon cable from the last SVT I had.

im pretty sure thats right. andy says that with the tt youd go from one 8ohm output into two 16ohm cabs, so i guess with your ad200b it would work the same.

I'm going to have to disagree...

If you're running the cabs in series (daisy-chaining), a 16 ohm out would be a correct match for two 8 ohm cabs.

Now, if you were running in parallel, two 16 ohm cabs would be correctly matched with one 8 ohm output.

While Orange guitar cabs are normally 16 ohms, the bass cabs are normally 8 ohms.

I believe there can be some (slight) tonal differences between the daisy chaining and linking from the two amp outputs. I'll try to dig into that later though 'cos right now I'm just off to bed after a night shift...

Snave, while daisy chaining may physically look like a series connection, ie one cab 'after the other', in fact it normally wires them electrically in parallel, ie 'one beside the other'. With parallel connections the overall impedance always goes down.

All input jacks on the Orange bass cabs are wired in parallell. Using good speaker cable (ie sufficient gauge wire) will likely not do anything to your sound when daisychaining. Only difference is the cable from amp to first cab has to provide both cabs. When daisychaining two 8 ohms cabs just use one of the 4 ohms outputs (these are also parallell like the cabs) and you'll be fine.

Most cabinets are parallel. If they were in Series, they would not work alone. The last speaker in line would have to be a standard wired jack as otherwise the circuit would be "Open" and none would work.

The other thing is that your amplifier output jacks would have to be re-wired in Series. The Positive lead to one jack and the Negative to the other. Your speakers would need two jacks each for this as well to complete the loop.
