2TR Digital Outs 43 Terminating External Wordclocks Wordclock signals distributed via BNC cables must be terminated correctly, otherwise, jitter and synchronization errors may result. Ideally, you should make a separate wordclock connection to each device and terminate it. The following examples show two ways in which wordclock signals can be distributed and how termination should be applied in each case. Normally the WORD CLOCK 75Ω ON/OFF switch should be set to ON. The OFF setting provides support for wordclock source devices with special specifications. Star Distribution In this example a dedicated wordclock distribution box is used to supply wordclock signals to each device individually. Termination is applied at each device. Wordclock master WC OUT (BNC) Wordclock distribution box WC IN (BNC) Device-A Termination = ON Wordclock slave WC IN (BNC) Device-B Termination = ON Wordclock slave WC IN (BNC) Device-C Termination = ON Wordclock slave WC IN (BNC) Device-D Termination = ON Wordclock slave Daisy Chain Distribution In this example the wordclock signal is distributed in a "daisy-chain" fashion, with each device feeding the wordclock signal on to the next. This method of distribution is not recommended for larger systems.

These outputs can be patched to the Bus Outs, Aux Sends, the Stereo Out, Input or Output Channel Insert Outs, or the Control Room signal (see page 56). They can also be patched to Direct Outs (see page 56). Digital output signals can be dithered for transfer to lower-resolution systems (see page 48). 02R96-Owner's Manual
