Accuphase DF-75 Digital Frequency Divider – High-Precision 4-Way Crossover
The Accuphase DF-75 is a state-of-the-art digital frequency divider designed for advanced 4-way audio systems. It offers exceptional control and clarity by separating audio signals with high accuracy and speed. Whether for home audio or professional setups, the DF-75 brings precision to every performance.
High-speed DSP for precise control
At its core, the DF-75 features a 64-bit floating-point DSP processor. This ensures fast, detailed signal processing. Furthermore, it gives you access to 3,101 crossover points, making system tuning easier and more accurate than ever.
Sharper sound with steep slopes
The DF-75 delivers a steep 96 dB/octave crossover slope. As a result, you get smooth transitions between drivers and minimal overlap. This leads to cleaner sound and a more defined soundstage.
Smart time and phase alignment
In addition to precision filtering, the DF-75 includes a delay function that adjusts time alignment in 0.5 cm steps. Moreover, its automatic delay compensator corrects for any timing errors caused by the filter circuits. These tools help ensure perfect timing and phase coherence across your system.
Versatile system configuration
The default setup supports full 4-channel output. However, you can also configure the unit for monophonic operation, allowing for more focused control in certain setups.
Premium converters for clearer sound
- A/D Conversion: Uses 4 parallel circuits with Accuphase’s ANCC (Accuphase Noise and Distortion Cancelling Circuit) for clean, accurate signal input.
- D/A Conversion: Features MDS+ and 4 parallel D/A circuits, also with ANCC, for smooth and natural sound output.
