Manufacturer's Description from UA

Elite  Audio  Conversion  with  Four  Unison  Mic  Preamps,  New  HEXA  Core  Processing  and  Surround  Sound  Monitoring

Apollo  x8p  allows  music  producers,  project,  and  post-production  studios  to  track,  overdub,  and  mix  with  new  world-beating  A/D  and  D/A  conversion,  HEXA  Core  UAD  plug-in  processing,  and  7.1  surround  sound  monitoring*  —  all  in  a  sleek  rackmount  Thunderbolt  3  audio  interface  for  Mac  or  PC. 

Built  upon  UA’s  60-year  heritage  of  audio  craftsmanship,  this  18  x  22  interface  distinguishes  itself  with  eight Unison™-enabled  mic  preamps,  providing  authentic  emulations  of  preamps  from  Neve,  API,  Manley,  Helios,  SSL  and  more,  plus  all-new  HEXA  Core  processing  —  yielding  50%  more  DSP  for  running  UAD  Powered  Plug-Ins  in  real  time.   

In  addition  to  its  elite-class  audio  conversion,  Apollo  x8p  features  selectable  operating  level  for  compatibility  with  professional  +24  dBu  gear,  as  well  as  an  integrated  monitor  controller  and  built-in  talkback  mic. 

  • Experience  elite-class  A/D  and  D/A  conversion  nearing  the  widest  dynamic  range  and  lowest  signal  to  noise  available  —  at  any  price   
  • Track  and  mix  with  powerful  HEXA  Core  processing,  featuring  6  UAD  DSP  chips  for  running  more  award-winning  UAD  Powered  Plug-Ins  in  real  time 
  • Record  with  near-zero  latency  through  preamp  emulations  from  Neve,API,  Manley,  Fender,  and  more  using  Unison™  technology*Easily  connect  to  pro-level  studio  gear  with  switchable  +24  /  +20  dBu  headroom  settings

Elite-Class  A/D  and  D/A  Conversion 

With  thousands  of  chart-topping  songs  and  hundreds  of  Grammy-winning  albums  under  their  belt,  Apollo  interfaces  are  no  strangers  to  tracking  stellar-sounding  records.  To  improve  on  the  previous  generation  Apollo  interface’s  class-leading  audio  conversion,  UA  engineers  obsessively  auditioned  the  latest  A/D  and  D/A  converters  —  ultimately  pairing  elite-class  24-bit/192  kHz  converters  with  all-new  analog  circuitry  for  an  ultra-pristine  signal  path.   

With  129  dB  dynamic  range  and  -118  dB  TD+N,  Apollo  x8p’s  open,  natural  sound  quality  rivals  any  dedicated  high-end  converter  on  the  market  —  regardless  of  price  —  and  is  the  perfect  starting  point  for  applying  UAD  processing.   

 Realtime  UAD  HEXA  Core  Processing

Apollo  x8p  features  new  HEXA  Core  processing,  with  six  DSP  chips  and  50%  more  UAD  plug-in  processing  power  than  previous  Apollos.  This  lets  you  run  more  UAD  plug-ins,  whether  you’re  tracking  in  real  time  with  channel  strips  from  Neve,  Manley,  or  API,  or  running  high  UAD  plug-in  counts  when  mixing  in  your  DAW.   

From  the  tube  warmth  of  Pultec  EQs  on  guitars  to  the  musical  tube  limiting  of  the  LA-2A  on  vocals,  or  the  pump  of  a  genuine  1176  or  Fairchild  670  tube  compressor  on  drums,  your  recordings  will  take  a  giant  leap  forward  with  a  rich,  three-dimensional  analog  sound  that  UAD  plug-ins  provide. 

Unison™  Technology:  The  Genuine  Sound  of  Neve,  API,  &  Manley  Preamps

Perfect  for  musicians,  engineers,  producers,  and  sound  designers,  Apollo  x8p  features  four  Unison-enabled  mic  preamps,  letting  you  track  through  exacting  mic  preamp  emulations  from  Neve,  API,  Manley,  SSL,  and  Universal  Audio.**  A  Universal  Audio  exclusive,  Unison  technology  nails  the  tone  of  these  sought-after  tube  and  solid  state  mic  pres  —  including  their  input  impedance,  gain  stage  “sweet  spots,”  and  the  component-level  circuit  behaviors  of  the  original  hardware.   

The  secret  to  Unison  is  its  hardware-software  integration  between  Apollo’s  mic  preamps  and  its  onboard  Realtime  UAD  processing.   

A  Full  Suite  of  Classic  Analog  Processing  Onboard

Of  course,  a  hallmark  feature  of  Apollo  is  its  Realtime  UAD  Processing,  letting  you  run  the  full  library  of  UAD  plug-ins  with  near-zero  latency.  Apollo  x8p  includes  the  Realtime  Analog  Classics  Plus  plug-in  bundle,  so  you  can  record  and  mix  with  the  world’s  only authentic  Teletronix  LA-2A,  1176LN,  and  Fairchild  compressors,  the  Unison-enabled  UA  610-B  Tube  Preamp  &  EQ,  and  guitar  and  bass  amps  from  Marshall  and  Ampeg. 

Access  the  World  of  UAD  Powered  Plug-Ins

Going  beyond  the  included  Realtime  Analog  Classics  Plus  plug-ins,  Apollo  x8  lets  you  tap  into  the  full  UAD  Powered  Plug-In  library  of  name-brand  vintage  EQs,  compressors,  reverbs,  tape  machines,  channel  strips,  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  SSL,  Neve,  Studer,  Manley,  API,  Ampex,  Lexicon,  Fender,  and  more,**  it’s  like  having  a  studio  full  of  iconic  analog  gear,  in  a  single  rack  space.  And  unlike  competing  interfaces,  these  award-winning  DSP-powered  plug-ins  are  also  available  in  your  DAW  for  mixing.

Surround  Sound  Monitoring*  and  +24  dBu  Operation

With  comprehensive  surround  monitoring  support  for  formats  up  to  7.1,  Apollo  x8p  is  a  boon  for  engineers  and  producers  working  on  audio  and  music  for  video  games,  television,  and  the  web.  In  addition,  Apollo  x8  offers  selectable  +24  dBu  operation  for  out-of-the-box  compatibility  with  professional  mixing  consoles  and  other  high-end  pro  audio  equipment.   

Build  a  Networked  Studio  System  Over  Thunderbolt

Apollo  x8p  offers  18  x  22  simultaneous  inputs/outputs  (8  x  8  analog  I/O)  and  two  built-in  Thunderbolt  3  ports,  which  are  backwards-compatible  with  Thunderbolt  1  and  2  Macs  via  adapter  (sold  separately).  This  allows  users  of  any  Thunderbolt-equipped  Apollo  Twin  or  Apollo  rackmount  audio  interfaces  to  easily  combine  up  to  four  Apollos  and  six  total  UAD-2  devices  —  adding  fast,  high-bandwidth  I/O  and  DSP  as  your  studio  grows.

Universal Audio

About Manufacturer

Universal Audio Inc. was re-founded in 1999 by Bill's sons, James Putnam and Bill Putnam Jr., with two main goals: to faithfully reproduce classic analog recording equipment in the tradition of their father, and to design new digital recording tools with the sound and spirit of vintage analog technology. However, as Bill Jr. recounts, the genesis of "UA, part 2" is actually a bit more serendipitous.

Having grown up in the music industry, Bill Jr. and James ("Jim") Putnam naturally assumed that the music business is where they'd eventually end up. Jim, a touring musician and recording engineer, and their older brother Scott, a studio designer in Southern California, were the first to follow in Bill Sr.'s path. However, Bill Jr. took a more circuitous direction, working for a number of engineering companies before undertaking a doctorate in Electrical Engineering at Stanford University. It was at Stanford that Bill Jr. became closely involved in the Center for Computer Research in Music and Acoustics (CCRMA), specializing in signal processing. It was also at Stanford that Bill Jr. began to assemble a team of the best and brightest minds in the field — who continue to steer many of Universal Audio's engineering efforts to this day.

However, the precise event that led Bill and Jim to start (or "reinvent") Universal Audio in 1999 was unexpected. As Bill Jr. tells it, when Bill Sr. passed away in 1989, he and Jim were faced with the Herculean task of cleaning out their dad's workshop and storage areas. While going through Bill Sr.'s old test equipment, boxes of parts, bits and pieces of consoles, and half-cannibalized 1176 compressors, Jim came across their father’s old design notebook. The two spent the evening poring over his notes, realizing that this was the map to every technical problem their father had ever solved. It was at that moment that they decided to bring back Universal Audio and its classic products. 

Fast forward a decade. Now with nearly 80 employees and legions of new customers worldwide, UA is headquartered near the Silicon Valley, in Scotts Valley, California — where our classic analog gear is still hand-built, one unit at a time. The lengths we go to deliver the exact sound and performance of classic analog audio gear is unparalleled; in fact, the goal is for UA's modern units to perform identically to well-maintained units built decades ago. 

Of course, analog is only half the story. At Universal Audio, we employ the world's brightest DSP engineers and digital modeling authorities to develop our award-winning UAD Powered Plug-Ins platform, featuring the most authentic analog emulation plug-ins in the industry. Our DSP gurus work with the original hardware manufacturers — using their exact schematics, golden units, and experienced ears — to give UAD plug-ins warmth and harmonics in all the right places, just like analog.
