nanoClocks

master clock generator and wordclock distributor

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.

MIF3

simultaneous LTC and MTC to LTC or MTC converter

The MIF3 generates LTC and MTC simultaneously from LTC or MTC sources. Consequently the box can be used as LTC to MTC and MTC to LTC converter as well as LTC and MTC refresher. Rosendahl sync algorithms suppress time code jitter and drop outs to allow the use of unstable, jittery MTC sources produced by most PC and MAC based audio workstations. In the generator mode the unit works as a MMC (Midi Machine Control) controlled virtual machine with MTC and LTC outputs. Most DAW and MIDI-Sequencer programs can output MMC commands for start, stop and locate functions. The time code outputs follow positional, reverse and looped time code. Instant cue software stops and restarts the time code slaved systems when the master time code is looping or jumping. Eight internal DIP switches serve to enable special functions as midi output mode for cueing, time code standard conversion (electronic gear box), time code speed measurement and the standard default setting. The interface has a robust aluminium housing, a large 7-segment LED display and a built-in power supply. An optional rackmount kit for fitting the unit into a 19 inch rack is also available.

• Generates LTC and MTC from LTC or MTC
• MMC (midi machine control) controlled MTC/LTC generator
