(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 27.

(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.
