Why is there a PEQ (parametric EQ) filter set outside a drivers pass band or beyond its crossover frequency?
There are typically one of two reasons for such filter settings. • A PEQ can be used to reduce the level of a transducer anomaly that, while outside its normal operating range, still affects the overall performance as a bump or ripple in the frequency response. • A PEQ can be used to modify a transducer’s phase response or output level near the crossover region. Optimum summation of two transducer’s outputs occurs when their phase responses have a similar value and slope at a particular frequency. Placing a filter at or near crossover can be used to create a phase and/or magnitude change that optimizes the summation of the sound from the two transducers. • Using the output gain given in your processor settings, there seems to be too much LF, MF, or HF. Why is this? EAW processor settings assume that all the amplifiers in your system have identical voltage gains. Note that this does not mean identical input sensitivities. Voltage gain is the ratio of input to output voltage and remains
