Am I hearing you right? Experimenting around with the input & output sources in not likely to cause damage?
NoNoNoNoNo!!!!! Experimenting with input
& output sources IS hazardous! :shock: Just as Bob said in his post....NEVER contect a speaker output into the front end of another amp!
On "most" 2 input amps (input 1 is high gain, input 2 has a 6db pad), both inputs are connected. So the input signal from one, is "present" in the other.
Here's the requested geezer friendly explanation:
"They are meant to have to
guitars share the same channel, or in the event of too strong a
signal that would cause distortion to the first stage, the input 2 is
padded down 6 dB from input 1. Conveniently, when sending a signal
into one jack, it will also appear on the other jack if something is
plugged into it, thus can be used as a source for another amp. There
is usually not much denegration of the signal, but it depends on what
amps and what guitars are used. To check, turn the volume down all
the way on amp #2 and unplug and plug back in to the unused input on
the channel of amp 1 with your instrument hooked up and playing to
see if it makes a diff having amp #2 plugged in. Use several diff
volume settings to see.
Make sure the amps are phased correctly if they are to be used with
the baffle boards of the speakers lined up in the same plane. You
don't want the speakers of one out of phase with the speakers of the
other."
Jeff, are you familiar with DI boxes & how they function. That's likely your "Direct Out"
