User Manual
Insert the graphic equalizer between the signal source (usually a mixer) and the
power amplifiers (or the crossover if there is one). Adjust the level and equalization as
required to yield the desired system response.
For optimum signal-to-noise response, the gain structure of the sound system must be
properly set up. Each component of the sound system should be set at its nominal
operating level, starting with the first element in the system, usually a mixing console.
Each element should be run at its nominal operating level in order to take advantage
of the maximum signal-to-noise properties of that element. Loudspeaker amplifiers, as
the last element in the chain, should be set only as loud as necessary, in order to
avoid inducing unnecessary noise into the system.
