One of three models in a family of cinema crossover accessories designed for QSC’s DCA Digital Cinema Amplifiers. These products were designed to interface with the Display Port on the rear of the amplifier, replacing the native inputs and drawing its power from the same port. The SF-3 shown here utilizes a 4th order Linkwitz-Riley low pass filter, a 2nd order frequency shaped high pass filter, and level shifting. As with other models in this line, parameters are SIP resistor programmable.
