I Googled the Furman Mixer and it looks like a pretty old piece of gear. I imagine the specs are pretty much what you would find on much newer gear. I assume it would be a signal processer only. The EIA Standards were most likely used of which means
the signal out put would be about ! Volt Peak to Peak of what a main amplifier would require to drive an amp to full out put. It appears there are level/volume controls to adjust the output so as to not over drive a recording device.
