this allows both amps to work on the same load doubling the power of each single amp. designed for stereo but configured in what's called a bridge mono configuration. On a valve amp this is done with different taps on the output transformer.Ī class D amp can do this automatically but the SD Powerstage is a little different form a normal class D amp. So when the impedance of the speaker rises the voltage of the amplifier has to rise to achieve the same power. However, the SD says output impedance is 4-8 ohms, meaning it doesn’t have the power available to go into a 16ohm? Or am I also misunderstanding ohm ratings (which isn’t unlikely)

You don't want to be using that for anything but noodling at home, really.

I've no idea why you'd want to, because then you're only hearing a simulation of a speaker instead of the real thing, but.Ī 1x10' is always going to sound thin and lacking in balls, though. The other thing with the SD is.you can use it to power a full-range cab if you want, like a PA monitor or cab. In any situation where you're using a 1x12' - usually noodling at home, or on a quiet stage with a mic in front of it, again you're in the situation where the cab will put out more volume than you'll want to use before any damage occurs. There is no hyperbole present when I say that you'll break your ears before you break the speakers.Ī 1x12' will usually be at least 25-30W, and if it's a Celestion speaker rated at that then it can usually do at least 20-30% more without any signs of imminent death. Those are the cabs you're going to use with a band - most 2x12' cabs have at least 50W or 60W speakers in them, often 100W speakers (like my Matrix and Jet City cabs), so you've got absolutely no worries there. Think of it like this: a 2x12' or 4x12' will be at unusable volumes before you blow them, simple as that. I’d like to try out this SD before buying with a smaller and bigger cab, but also I want to see how much difference it makes compared to a good sized FRFR speaker, like the headrush or Alto ones (or the laney LFR that looks like a proper cab so wins points there!). Headroom matters when you're talking about modellers and solid state amps that's where the low-end clarity comes from.

Your cab is 16 ohm, isn't it? That DV Mark head put 25W into that. Guitar-Helix-SS amp head FX return-cabinet One of these for example (picked at random, no reason specifically for this model) I’m not super bothered about the SD being pedal format, it’s not really a concern for me to carry a small amp head instead What if I looked for a high wattage solid state amp head with an effects loop? I could then run the helix into the loop and then into whatever cabinet I wanted to right? Since it’s only going via the effects loop and not the regular input, I’ll get all the volume (and clean headroom since it’s solid state) which would then keep all the tone from the helix
