Accuphase DF-75 Digital Frequency Dividing Network

The DF-75 is a digital active crossover for multi-amp speaker setups, giving serious system builders precise control over how each driver is fed.

A 64-bit floating-point DSP handles the filtering with an unusually fine 3,101 selectable cutoff points and a steep 96 dB/octave slope, supporting up to 4-way active systems. Time-alignment delay adjustable in 0.5cm steps, with an automatic delay compensator, helps keep drivers in phase with each other.

• High-speed, high-precision DSP realizes fully digital signal processing in channel divider units
• Standard configuration allows 4-channel (4-way) system setup
• Impressive 3101 point cutoff frequency pointss
• Steep 96 dB/oct attenuation slope
• Delay function to adjust delay time settings between different speaker units
• Delay compensator automatically corrects delays in filter signals
• A/D converter driving 4 parallel circuits using ANCC
• MDS+ D/A converter driving 4 parallel circuits using ANCC
• Selectable monophonic output mode for enhanced specifications
