(7) 75 Ohm Word Clock Termination Switch
This pushbutton switch provides internal 75-ohm word clock input signal termination when required. Word 
clock termination is active when the switch is engaged (depressed).
Apollo 16’s termination switch should only be engaged when Apollo 16 is set to sync to external word clock and 
it is the last device at the receiving end of a word clock cable. For example, if Apollo 16 is the last “slave” unit 
at the end of a clock chain (when Apollo 16’s word clock out port is not used), termination should be active.
Note: For more information, see “Digital Clocking Basics” on page 26.
(8) AES/EBU Ports
The AES/EBU ports provide two channels of digital I/O with resolutions up to 192 kHz via XLR connectors. For 
optimum results, use only high-quality 110-ohm XLR cables specifically designed for AES/EBU digital audio.
SR Convert
Sample rate conversion can be enabled on the AES/EBU input. This function is set in the AES/EBU input chan-
nel strips in the Console application. When sample rate conversion is enabled and the sample rate of the 
incoming AES/EBU signal does not match the sample rate specified in the Console application, the AES/EBU 
signal is converted to match Apollo 16’s sample rate.
Note: When Apollo 16 is set to use AES/EBU as the master clock source, sample rate conversion is 
inactive.
Mirror Monitor Outputs
The AES/EBU output can be configured to mirror the Monitor outputs, for routing the stereo Monitor signal to the 
stereo AES/EBU input of other devices. This function is configured in the Interface panel of the Console Settings 
window in the Console application.
