About UAD Powered Plug-Ins Processing
Two Distinct Methods with Apollo
Apollo features two distinct methods for using UAD Powered Plug-Ins: The “Console
processing method” for low-latency monitoring and tracking with Realtime UAD Process-
ing via the Console application, and the “DAW processing method” for DSP-accelerated
UAD-2 processing via VST, RTAS, AAX, and Audio Units plug-ins in DAW applications.
These two methods are not a switched mode, but instead simply depend on which ap-
plication (Console or DAW) uses the UAD plug-ins. Both methods can be used simultane-
ously for extremely powerful and flexible signal monitoring, routing, and processing.
Console Processing Method
UAD Powered Plug-Ins run in realtime only when used within Console. Using Realtime
UAD Processing in Console is optimum for artists and engineers that need to monitor and
capture performances without DAW I/O buffering latency and its associated hindrances.
The special Realtime UAD Processing functionality is achieved via Apollo’s unique ultra-
low latency DSP+FPGA+Console design. Although every audio interface has undetectable
latency that is inherent to the A/D–D/A process, routing Apollo’s input signals through
UAD Powered Plug-Ins within Console does not add to this inherent latency.
Up to four UAD plug-in instances can be inserted serially (“stacked” or “chained”) on
each of Console’s analog/digital inputs and/or auxiliary buses simultaneously, without
adding to the inherent I/O latency.
Note: Upsampled UAD plug-ins add latency when used within Console or a DAW.
See
“Upsampled UAD Plug-Ins” on page 115 for more information.
Console inputs with Realtime UAD processing can be routed into the DAW via Apollo’s
device drivers, and optionally recorded as either processed (wet) or unprocessed (dry)
audio using the
Insert Effects function in Console.
Important: UAD plug-ins used within Console for Realtime UAD Processing must
run on the DSP within Apollo. If other UAD-2 devices are active in the same sys-
tem, DSP on those devices cannot be used for Realtime UAD Processing.
