Main Apollo x16D front panel elements (3) Channel Level Meters The 10-segment LED channel meters display the input or output signal peak levels for network channels 1 – 16. Input or output metering is selected with the METER switch (#9), and the input/output state is shown by the METER indicators (#6). The dB values of the meter LEDs are indicated between the meters for channels 4 &...

Internal Clock When set to internal clock, the INT indicator is illuminated white. External Clock Apollo x16D can use an external digital clock source from the Word Clock, AES/EBU, or network inputs. The EXT indicator has two possible states: White – When set to external clock and a valid clock signal is detected at the specified port, the EXT indicator is illuminated white and Apollo x16D is synchronized to the external clock source.

(8) Monitor Output Level Meters The 10-segment LED meters display the signal peak output levels of the rear panel Left & Right Monitor outputs at the output of the D/A converters. These meters are before the Monitor Level control (pre-fader) and reflect the D/A converter levels regardless of the current Monitor Level and Headphone Level knob settings.

Attenuates the signal level at the monitor outputs by the dB amount set in the CONTROL ROOM strip within the UAD Console application. The Monitor Level Indicator ring (#12) flashes when DIM is active. TALKBACK Activates the talkback mic and the DIM function. Talkback is active when the button is lit.

Flashing – The monitor DIM, MONO, and/or TALKBACK functions are active. (13) Power Switch This switch applies power to Apollo x16D. When the unit is powered on, the Universal Audio logo (#1) is illuminated. The external power supply must be properly connected for this switch to function.
Rear Panel (14) Power Input The included external power supply connects to this 4-pin locking XLR jack. Apollo x16D requires 12 volts DC power and draws a maximum of 72 watts (30 watts typical). To eliminate risk of circuit damage, connect only the factory-supplied power supply. Use the Power switch on the front panel to power the unit on and off.

(16) 75 Ohm Word Clock Termination Switch This switch provides internal 75-ohm word clock input signal termination when required. Word clock termination is active when the switch is engaged (depressed). Apollo x16D’s termination switch should only be engaged when Apollo x16D is set to sync to external word clock and it is the last device at the receiving end of a word clock cable.

(18) AES/EBU Ports The AES/EBU ports provide two channels of digital I/O with resolutions up to 24-bit at 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.

(19) Left & Right Monitor Outputs These balanced XLR jacks are line-level analog outputs typically used for connection to a stereo loudspeaker monitoring system. The signal levels at these outputs are controlled with the Monitor Level & Mute knob (#11). The Monitor Outputs are DC coupled. The Monitor Outputs can be configured to use an operating level of +4 dBu (default value) or -10 dBV.
Interconnections Installation Notes • Apollo x16D may get hot during normal operation if it doesn’t receive adequate airflow circulation around its chassis vents. When mounting Apollo x16D in a rack, leaving at least one empty rack space above the unit to allow adequate airflow for cooling is recommended.
Apollo Expanded When more I/O and/or DSP is needed, up to four Apollo interfaces and six UAD devices total can be cascaded together via Thunderbolt in a multiple-unit configuration. For complete details about multi-unit cascading, refer to the UAD Console Manual.
Software Setup Note: Items on this page are detailed in the Apollo Software Manual. System Requirements All system requirements must be met for Apollo x16D to operate properly. Before proceeding with installation, see the system requirements in the Apollo Software Manual. Software Installation The software must be installed to use the hardware and UAD plug-ins.
Specifications All specifications are typical performance unless otherwise noted. Tested with the Audio Precision APx555 Audio Analyzer under the following conditions: 48 kHz internal sample rate, 24-bit sample depth, 20 kHz measurement bandwidth, +24 dBu headroom, balanced output, and internal clock. Specifications are subject to change without notice.
