Apollo Thunderbolt Software Manual Console Reference 80
Sample Rate Display
This area displays the current sample rate used for Apollo’s A/D-
D/A conversion and UAD Powered Plug-Ins processing. When
using UAD Powered Plug-Ins, higher sample rates require more
UAD DSP resources.
Important: When the Clock Source parameter is set to use any external clock
source, the sample rate must be manually set to match the sample rate of the
external clock.
Sample Rate Menu
Clicking the Sample Rate Display presents the Sample Rate Menu,
where the current sample rate can be changed.
Important: When a DAW is used with Apollo, the sample rate is
typically changed within the DAW settings. If the sample rate is
changed to a different value within Console when a DAW is active,
digital artifacts could occur due to a sample rate mismatch.
Apollo Twin Note: If the current digital input setting is S/PDIF and
the sample rate is changed to a rate higher than 96 kHz, the clock
source is changed to Internal and the S/PDIF inputs are no longer
unavailable.
Clock Display
The Clock Display has three functions: It shows the currently
selected clock source, facilitates selection of a different clock
source, and indicates when the selected clock source signal is
not detected.
Clock Source Menu
Apollo can synchronize to its internal clock or an external clock
(word clock, ADAT, S/PDIF, or AES/EBU; available clock sources
depend on the connected Apollo hardware). To select a clock
source, click anywhere in the clock display area to view the Clock
Source Menu, then select a clock source from the menu.
Tip: The clock source can also be specified in the Hardware
panel within the Console Settings window.
