DF-75 Digital Frequency Dividing Network

The DF-75 Digital Frequency Dividing Network can support 4-way system setups. The high-speed 64-bit floating point DSP allows for optimal filtering. Cutoff frequency points have been expanded dramatically from 59 to 3101, accommodating a variety of performance demands. The network also achieves a steep 96 dB/octave attenuation slope. Beyond that, the time delay function allows for time alignment in 0.5-cm steps while a delay compensator automatically corrects signal delays in the filter circuits. Each divider unit can also be configured in a monophonic setting.
