Rosendahl Nanoclocks Rack Audio Word Clock Server

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).
