Is it possible to use a GA-10 Yamaha guitar amplifier as a computer speaker?

I'm hoping to use a spare guitar amplifier as a speaker for my pc. Is it as simple as getting the right cable or will there be hard-wiring involved?

Thank you Internet Tech Gods!
Thank you!



Answer
It is possible, but there are good reasons to not do it:

>> The amplifier's input sensitivity is rather high
compared to that of a typical powered "computer speaker",
so you'd have some volume-control difficulties
(it would get too loud too fast as you increased
the output level of the source).

>> The overall frequency response of a guitar amplifier is typically
designed specifically for guitars, not for hi-fi sound sources.
The common result of connections such as you are asking about
is very tinny sound (lots of treble, but little bass).

>> The guitar amplifier is a single-channel (mono) item,
so if you wanted to hear both channels of the source
without having to tolerate severe distortion,
a custom-made (passive resistive mixing) cable
would be the most practicable method of connection.
