DF-65 Digital Frequency Dividing Network

The Digital Frequency Dividing Network DF-65 harnesses the very best of digital technology in
every aspect, including 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 offer 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 provides high versatility for various configurations.
