The power-packed, dynamic Accuphase DF-65 Digital Frequency Dividing Network is now available on Ooberpad. The Digital Frequency Dividing Network DF-65 leverages the very best of digital technology in every aspect, that comprises a high-speed 40-bit floating point DSP. The standard unit configuration supports signal processing for up to four-way systems. Highly accurate digital filters provide a choice of 59 cutoff frequency points and up to 96 dB/octave attenuation. Integrated time alignment function adjustable in 0.5-cm steps, and delay compensator for automatically offsetting any filter circuit delays. Monophonic output mode renders high versatility for various configurations.

    Benefits of Accuphase DF-65 Digital Frequency Dividing Network:

    High-speed, high-precision DSP implements fully digital signal processing
    High-speed, high-precision DSP implements fully digital signal processing

    Designed to serve as the core component of a multi-amped system, the channel divider DF-65 features high-speed digital signal processing with amazing power. Latest digital circuit topology and advanced technology come together in a floating-point DSP that has a 32-bit mantissa and 8-bit exponent section, serving as digital filter. The division into mantissa and exponent prevents errors even when handling very small values. This results in dramatically improved dynamic range and superior precision, allowing very steep cutoff slope settings of 48 dB or 96 dB per octave. All other functions including phase, delay, and level control are also implemented in the digital domain. The result is ultra-precise filtering free from adverse effects by temperature changes or aging.

    59 selectable cutoff frequency points
    59 selectable cutoff frequency points

    Filter frequency points can be set over the range from 31.5 Hz to 22.4 kHz in 1/6-octave intervals. In addition, 10, 20, and 290 Hz points are also provided, resulting in a total of 59 points. Each divider unit is fully flexible and allows independent selection of lower and upper cutoff frequency.

    High-performance HyperstreamTM DAC used for MDS++

    MDS (Multiple Delta Sigma) is a revolutionary design that employs multiple delta-sigma type D/A converters connected in parallel, for drastically improved performance. In the DF-65, four HyperstreamTM DAC chips (ES9018S made by ESS Technology) of the latest generation are driven in parallel. Compared to a single converter, this results in an overall performance improvement by a factor of 2 (= √4).

    Time alignment function allows delay adjustment in 0.5-cm steps

    The DF-65 incorporates a DELAY function that uses digital signal processing to electrically adjust the time when the sound from each driver reaches the listener. Normally, a delay would be expressed as a time value, but since the delay here is caused by spatial distance, the DF-65 converts it into a distance value (cm) for display.
