![]() They are also MUCH cheaper than the Neutrik problem solvers. AES11 is basically a standard AES3 signal which carries an accurate clock reference. Anyway I'm considering using Murata DA102C transformers (). Word clock is a simple square-wave signal running at the sample rate, and most devices are equipped to synchronise to an external word clock signal. There are some clock distribution amplifiers which have transformer isolated WC inputs, though. Usually there seems to be none, for an example the Symetrix GEN圆 doesn't have any in the input or output: No I'm wondering if I should really use a pair of transformers in the WC output circuit. To isolate ground potentials galvanically and for interfacing coaxial to balanced AES11 lines (XLR 3-pin) we recommend Neutrik Digital Audio Impedance Transformers NADITBNC-F / NADITBNC-M." Good studio grounding is essential, not only for word clock signals. The precise timing of digital audio samples is critical to the correct operation of interconnected digital audio equipment. Transmission lines can be worsened/ modulated by ground loops. As the Rosendahl nanoclock manual says it "Similarly to analogue audio signals producing "hum" affected by different ground potentials, digital I need to put a pair of wordclock outputs on my ADAT ADC board (just a small adaptor PCB to supply I2S clocks and power to recycled E-Mu 1820M ADC board) and I've bee wondering why use the optical ADAT with the coaxial WC as those mostly seem to be unbalanced and relying to clean ground connections so you will loose all of the benefits of the optical interface.
