Apollo Thunderbolt Software Manual Console Settings 141
Sample Rate
This setting defines the sample rate that is used for Apollo A/D and 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.
Note (Apollo Twin and Apollo 8p): 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 Source
This setting determines the master clock source for A/D and D/A conversion. The
available values are:
Apollo, Apollo 8, Apollo 8p – Internal clock or external clock from S/PDIF, ADAT, or Word
Clock
Apollo 16 – Internal clock or external clock from AES/EBU or Word Clock
Apollo Twin – Internal clock or external clock from S/PDIF or ADAT
If the Clock Source setting is not set to Internal and the external clock signal is not
detected, then the text in the Clock Source display is RED (if this occurs, verify
connections and external clock device settings).
Note: Only one device in a system can be the master clock. This setting must
match the host DAW setting or audio glitches and/or distortion could occur.
Buffer Size (Windows)
Note: This setting is available on Windows systems only. On Mac systems, the
hardware I/O buffer size is set within the DAW application.
This setting determines the hardware I/O buffer size used by a DAW. As values are
decreased, DAW throughput latency decreases, but the computer’s CPU load increases.
Conversely, as values are increased, DAW throughput latency increases, and the
computer’s CPU load is reduced. For related information, see Latency Basics.
Available buffer size values are dependent on the current Sample Rate value. If values in
the Buffer Size menu are gray and cannot be selected, change the Sample Rate value.
Note: If audio artifacts occur during DAW playback (clicks, pops, stuttering, etc),
the buffer size may need to be increased.
Important: Buffer Size applies to use with a DAW only. It has no effect on
Console’s hardware monitoring features or Realtime UAD Processing within
Console.
