This monitor jack is set up to feed another power amp.
While it has close to 4 volts of output it does not have the needed current to drive a speaker.
This level of voltage outout is dependent on how loud you play the amp and with 3 to 4 volts of potential outout you will need to pad it down if you pump it into a mixing board.
Even 3 volts is hotter then zero DB line level input.
