Accuphase DF-75 Digital Frequency Dividing Network
High-end 4-way digital crossover for multi-amplified systems requiring supreme precision, timing control, and flexibility.
The Accuphase DF-75 Digital Frequency Dividing Network is a state-of-the-art active crossover designed for audiophiles who demand ultimate control and transparency in multi-amplified systems. Using advanced 64-bit floating-point DSP technology, the Accuphase DF-75 delivers precision crossover management with ultra-fine adjustments for frequency, slope, level, delay, and phase alignment.
With support for up to four channels in a 4-way configuration, the DF-75 offers an extraordinary 3,101 selectable crossover frequency points, far surpassing conventional designs. Filter slopes are adjustable from gentle 6 dB/octave to an extremely steep 96 dB/octave, allowing seamless integration between amplifiers and speaker drivers.
Time alignment is handled with precision delay control in 0.5 cm increments, plus an intelligent delay compensator that automatically corrects signal timing between channels. This ensures perfect phase coherence and imaging accuracy in complex audio systems.
Equipped with both analog and digital connectivity, including balanced XLR outputs and high-performance ANCC A/D and MDS+ D/A conversion, the Accuphase DF-75 fits perfectly into hybrid or fully digital setups. Its engineering and component quality uphold Accuphase’s reputation for precision, purity, and long-term reliability.
