How would I use the line out feature without damaging this amp??? I have only one input on y Focusrite, so I could use only one line out.
How To Safely Use the Valvestate 8200 Line Outs:

- Start date
What model interface is this?

Im not sure about the amp's load need, assuming it still needs a speaker load? ( SOME SS amps are capable of operating without one but you might wanna check this first for this amp!) But typically, if you do have a speaker load and use the line out, it should go directly into the input of your Focusrite. Its meant to work by plugging directly into a PA or mixing console, so maybe it doesnt need a load?
Yeah, I wouldn’t run the amp without a speaker load…not an amp from that era.
But…..
He also states that his Focusrite interface only has one input. I am not familiar with a single input Focusrite interface model. Even the solo has two inputs.(one mic and one hiZ)

Admittedly i am not familiar at ALL with Focusrite, so probably talking out of my league here but would this be it? It looks like one XLR Input and one 1/4" Jack Input with a 1/4" Headphone Input if im seeing this right. Back looks like two 1/4" Line Outputs and a USB?
That’s why I asked what interface he was using.
It always peaks my curiosity…these types of questions.
Just a further reply, while we wait for an answer, if that is the interface model….it has no “line inputs”…only instrument(hiZ), and mic preamp(need a DI maybe, to go from line to mic level).

SS power section should need no load.
Just like any PA or other SS amp I have ever dealt with. Apparently there is one "special" SS amp that needs a load but that isn't it.
No load is like an infinite load for SS.

Ive heard this many times on Solidstate amps in the past, actually! I never been brave enough to try it personally lol apparently hybrids, on the other hand cant do this IF the output is valved. So my understanding of that would be like the old Marshall Artiste where you have an SS preamp and a valved poweramp. Marshalls like the Valvestates and Mode Fours however, are the opposite with valved preamps and SS power amps, so essentially they are the same as a regular SS amp that can do this.
I do know that SS amps suffer when there is not enough load, cause I blew up a Mode Four by using 8ohm cabs into 16ohm outputs ( young and dumb!). But oddly enough, I could have had the amp unplugged entirely and it wouldve just sat there according to the Marshall repair tech. Go figure. I know in a valved Marshall, that's an instakill lol

Yup exactly all that. Have had it happen many times over the years with PA amps. No,problem at all, it is the nature of the beaet. The 8200 is a SS power section so no load required.
The JMD is valve power section so you need a load. Don't run a low like 2 ohm load on a 4 ohm minimum SS at full bore as example. No load becomes infinity amd totally safe
Right…with very few exceptions…I had a powered mixer that required a speaker load be connected(per the manual).
Mosfets do not like heat…that should be monitored.
OP
Good! You have a version that is switchable from hiZ to line level on input 2. The current version(3 IIRC) does not have that function.
You can buy a line to mic level converter/pad, and run full stereo that way…
OP
So, basically, unhook speakers and run a line put cable to the interface?
The manual doesn't address this situation.

I need to see how you would do that!

The line out indeed works.
You should not need to disconnect the speakers.
OP
I'm thinking, that if I could run a cable from each line out, that may mute the speakers, but my interface (Focusrite 2i2) doesn't accept more than one instrument cable.
I’m not sure if using the line out mutes the speakers. You’ll just have to try it.
It may be designed so the line out is independent of the master out. This would allow you to turn the master down, while still allowing the line out to feed the desk. Some AV gear is designed like this.
Again, try it and see what you get.

Thanks, I'll give that a try.
