DBX 2/3/4 Way Audio Crossover
All the inputs and outputs are XLR balanced jacks that are bolted down to the chassis. This “nutting down” of the jacks insures that even if someone steps on a cable plugged into the unit, it’s not going to tear up the circuit board inside. All dbx crossovers feature Linkwitz-Riley 24 dB per octave filters, the professional standard, ensuring a premium quality audio processing.
