Rosendahl NanoClocks

Overview

Nanoclocks is a word clock distributor with integrated audio master clock generator, dual inputs with frequency status indicators and programmable output matrix - a flexible tool for all extensive digital audio installations. The unit provides two transformer isolated word clock inputs and 12 word clock outputs to receive and distribute word clock signals over long distances. Ground potential variations, similar to earthloop induced hum in analog audio, can cause jitter in clock signals, a transformer isolated input eliminates this effect. In operation mode DISTRIBUTOR the two inputs A and B can be routed individually to each of the 12 outputs. Ten LEDs on the front panel indicate the sample rate of the incoming signals. Input B also accepts Fs x256 signals (also known as super clock). GENERATOR mode changes the unit into a ultra low jitter audio master clock generator with 12 programmable outputs. Supported sample rates are 44.1, 48, 88.2, 96, 176.4 and 192 kHz as well as the respective super clocks (Fs x256). FAILSAFE mode is a broadcast application, which monitors the two input signals and performs an automatic switch over of all 12 outputs if the primary word clock signal fails
