Description

Most electrical signals are single-ended, comprised of a single wire and ground. Differential signals use two wires which are the inverse of each other -- when one swings positive, the other swings negative in equal magnitude.

Hi All, I recently had an old FurmanPQ6 parametric modded from unbalanced to balanced. When I attempt to use it via a channel insert, I can see signal getting to the unit via the overload LED at the input level pot, but I can't get return signal to the channel. If I return signal to another channel by way of individual patch cords rather than send/return type, I get signal, but not much.
