I want to take one of my amp speaker outputs and convert it to a line-out. Th amp is a Deluxe Tweed 5E3 with 4ohm and 8 ohm outputs. I use the 8 ohm output to the speaker in the cab which leaves the 4 ohm output. I understand that the 4 ohm output can be modified with a proper pad ... in line 2k2 with a 200R to ground. I also have a device Archer 274-016 that is a lo-z blanced hi-z unbalanced adapter ..... 1/4" to xlr female. I have then a male xlr to 1/4 that converts it back again. The idea is to have a line out from the amp into another amp that has various effects on the second amp. Question is - will these lo-z hi-z devices work to transport the signal to the next amp from the 4 ohm output in the first amp.

ange, Exactly where in the second amp to you intend to inject your "line out" signal from the first amp? Or perhaps more to the point, what amp are you contemplating using as the second amp? Reason I ask is that you've opened up a can of worms. Line Out means different things to different groups of people. See the Wikipedia article for a good overview of what you're up against, then report back with your answers. en.wikipedia.org/wiki/Line_levelsumgai |

Ok lets sort the worms. The idea is to take a " line out " to the front end of the next guitar amp.
Or first into a pedal board and then into the amp. Does that clarify?

I don't think you'll need any kind of impedance "matching" devices between the pad and the second amp. The output of the pad is going to be plenty low whether you run it into the normal instrument input or a line input like an effects loop or something.
You may have to adjust the pad itself depending on which input you're going into, so that it provides proper levels without unwanted distortion.

ange,
Short answer: no.
The fact is, a guitar amp's input expects to see a quite high impedance, at a voltage about half of the standard Line Level. (Ditto for stomp boxes.) If you drive it with a true Line Level signal, you'll likely encounter distortion. Hence, we pad such incoming signals both to reduce the level and to set the correct impedance.
Question: are you taking the signal from the (4Ω) output jack because it's convenient, or because someone told you "that's the way it's done", or because you are trying to get "that tone" that you hear coming out of your speaker?

FWIW (in this case, not much I suspect),
I have an old Peavey Studio Pro 50 amp (it is solid state) that has a ¼” balanced line out, which I sometimes run to the input of a second amp (also solid state) …
I don’t know why I do this … I guess it’s because I have an extra amp that I never use and I feel like the two of them together offers some kind of cool stereo effect or looks like a mini-stack or something (I know that it actually accomplishes nothing stereo-wise, and very little tone-wise … not to mention looks-wise!).
Anyway, the line out won’t run headphones or anything, it’s only enough juice to give a signal to the other amp (or as a line into a computer or some other sort of recorder, if sufficient volume is used).
While I have not gained any wonderful tonal qualities out of this arrangement, I have noticed no weird noises of a detrimental nature or loss of signal or anything either.
The reason I think this is not terribly applicable to Ange’s situation is that the line is already purpose-built into the amp, as opposed to having been installed after the fact, in the manner in which Ange describes.
Like I said, FWIW (in this case, not much I suspect).
Happy New(ey)ear, everyone!

Yes, because its convenient, and because a sound " expert " friend is trying to convince me that using this device will enable the line-out to the next amp at the proper voltage. I do understand that this is commonly done with an L pad.... which I do not have installed in this amp yet. If I understand correctly ( ? ) the L pad would take the signal that is intended to go to the speaker and lower the voltage so that signal will be acceptable ( no distortion )to the next amp. But I think that this is not going to work out because an extension speaker out would be the same impedance as the main speaker out, and the tweed has a 4 ohm and 8 ohm speaker intended for two different speaker ratings. I probably have this all gummed up. Can you please explain what a balanced output is. a (EDITed by sumgai to make the quote display correctly.) |
