Apollo Twin MkII Hardware Manual Introduction 5
A Full Suite of Classic Analog Processing Onboard
Right out of the box, Apollo Twin MkII provides a suite of incredible analog emulation 
plug-ins including the world’s only authentic Teletronix LA-2A and UA 1176LN 
compressors, the legendary Pultec EQs, and the Unison-enabled UA 610-B Tube 
Preamp. Developed by UA’s world-renowned team of algorithm engineers, these Realtime 
Analog Classic plug-ins set the standard by which all other hardware emulation plug-ins 
are judged.
From the tube warmth of the Pultec EQ on guitars, to the gentle limiting of the LA-2A 
on vocals, or the pump of a genuine 1176LN compressor on drums, your recordings will 
take a giant leap forward in rich, sonically complex analog sound.
Access the World of UAD Powered Plug-Ins
Beyond the included plug-ins, Apollo Twin MkII lets you tap into the full library award-
winning UAD Powered Plug-Ins — including vintage EQs, Compressors, Reverbs, Tape 
Machines and more — at near-zero latency, regardless of your audio software’s buffer 
size and without taxing your computer’s CPU.
With exclusive emulations from Neve, Studer, Manley, API, Ampex, Lexicon, Fender, 
and more,* it’s like having an endless analog studio, right on your desktop. And unlike 
competing interfaces, these DSP-powered plug-ins are also available in your DAW for 
mixing.
Next-Generation A/D and D/A Conversion
Of course, the heart of any audio interface is the quality of its conversion. With the 
highest dynamic range and lowest noise of any desktop interface, Apollo Twin MkII gives 
you stellar 24-bit/192 kHz sound and breathtaking clarity. Its premium Unison mic 
preamps, input stage, and audio conversion are identical to the famed Apollo series, 
translating into rich three-dimensional recordings with exceptional depth and punch.
Apollo: The Choice of New-School Professionals
Apollo is the confirmed choice of hit-making professionals, used to record records 
by Kendrick Lamar (To Pimp A Butterfly), Coldplay (A Head Full of Dreams), Dr. Dre 
(Compton), Brad Paisley (Wheelhouse), and many more. The Apollo range of interfaces 
has earned numerous industry awards from Sound on Sound, Future Music and 
Electronic Musician — as well as the prestigious 2016 TEC Award for computer audio 
hardware.
Now with Vintage Amps and Stompboxes
Apollo Twin MkII also includes Unison technology on its front panel instrument input, 
giving you dead-on emulations of guitar and bass amps like the Fender ‘55 Tweed 
Deluxe, Marshall Plexi Super Lead 1959, and Ampeg B-15N Bass Amplifier, as well as 
iconic stompboxes.
