About Realtime UAD Processing
Apollo has the ability to run UAD Powered Plug-Ins in realtime. Apollo’s groundbreaking DSP + FPGA technology
enable UAD Powered Plug-Ins to run with latencies in the sub-2ms range, and multiple UAD plug-ins can be
“stacked” in series without additional latency. Realtime UAD Processing facilitates the ultimate sonic
experience while monitoring and/or tracking.
Realtime UAD Processing is a special function that is available only within the included Console software
application. All of Apollo’s analog and digital inputs can perform Realtime UAD Processing simultaneously, and
Console inputs with Realtime UAD Processing can be routed into the DAW for recording.
Important: Apollo, like other UAD-2 devices, can only load UAD Powered Plug-Ins that are specifically designed
to run on UAD-2 DSP accelerators. Native (host-based) plug-ins cannot run on the UAD-2 DSP.
Combining with other UAD-2 devices
Apollo can be used simultaneously with other UAD-2 devices (UAD-2 PCIe cards, UAD-2 SOLO/Laptop, UAD-2
Satellite, and/or another Apollo interface) in the same host computer system. Apollo simply adds to the DSP
availability (and with multiple Apollo units, additional I/O) when used with other UAD-2 devices during mixing,
increasing the DSP processing power so more UAD Powered Plug-Ins can be used. Up to four UAD-2 devices can
be combined in the same system; see the Apollo support web page for specific details.
Standalone Use
Although the Console application is required to unleash the full power of Apollo, the unit can be used as a
digital mixer with limited functionality without a connection to a host computer.
All currently active I/O assignments, signal routings, and monitor settings are saved to internal firmware when
Apollo is powered down and persist when power is re-applied. Therefore the last-used settings are always
available even when a host computer is not used.
Note that UAD plug-in instantiations are not retained on power down, because the plug-in files reside on the
host computer. However, if UAD plug-ins are active when Apollo’s connection to the host system is lost (if the
FireWire or Thunderbolt cable is unplugged), the current UAD plug-in configurations remain active for
processing until Apollo is powered down.
About Apollo Documentation
Documentation for all Apollo components is extensive, so instructions are separated by area of functionality, as
detailed below. All documentation is copied to the computer during software installation; Apollo documentation
can also be downloaded from our website at: www.uaudio.com/support/apollo
Note: All manuals are in PDF format. PDF files require a free PDF reader application such as Adobe Reader
(Windows and Mac) or Preview (included with Mac OS X).
Apollo Hardware Manual
The Apollo Hardware Manual contains complete information about the audio interface hardware. Included are
detailed descriptions for all Apollo hardware features, control functions, and connections. Refer to the
hardware manual (you’re reading it now) to learn all about interfacing the hardware with other devices,
operating the panel controls, clocking, specifications, and related information.
Apollo Software Manual
The Apollo Software Manual is the companion guide to the Apollo hardware manual. It contains detailed
information about how to configure and control Apollo’s software features using the Console application and
Console Recall plug-in. Refer to the Apollo Software Manual to learn how to operate these software tools and
integrate Apollo’s audio interface functionality into the DAW environment.
