AC Enhancer

Nordost’s QVIBE is an active line harmonizer that adds  a  carefully  calculated  range  of  harmonic  overtones directly onto the AC line. The QVIBE will drop  the  noise  floor  as  well  as  add  a  noticeable  increase   in   image   depth,   dimensionality,   and   realism of both musical and visual performance. The  function  of  the  QVIBE,  or  QV2,  is  two-fold.  Its  primary  purpose  is  to  transmit  additional  frequencies  onto  the  AC  line  that  impact  the  mid   and   upper   base   ranges   of   sound.   The   secondary  objective  is  to  remove  irregularities  in  the  sine  wave  that  could  negatively  impact  sonic performance. The active circuit board used in  the  QV2  is  programmed  to  emit  a  frequency  pulse  60  times  per  second,  mirroring  the  peaks  and troughs of a sine wave. These precisely timed bursts  help  to  maintain  the  shape  of  the  wave,  VIBE — AC LINE HARMONIZER where there could be tendencies for it to collapse, eliminating any harsh quality to the sound.The  QVIBE  is  housed  in  a  mechanically  tuned  carbon-fiber body and equipped with either gold-plated US (NEMA) or EU (Schuko) connectors. It is  compatible  with  voltages  from  110V  to  240V,  and can be used with a Schuko/AUS or Schuko/UK adaptor if required. The QV2 is most effective when  placed  in  close  proximity  to  your  system,  and  should  ideally  be  plugged  into  your  QBASE; however,  its  results  can  be  heard  when  placed  into  any  spare  socket  on  your  system’s  AC  line.  While  the  QVIBE  can  be  used  by  itself,  its  sonic  impact is cumulative, and using two or four QV2 devices  will  more  than  double  or  quadruple  its  results.  The   QKOIL   is   a   load   resonating   coil   (LRC)   enhanced  with  Nordost’s  patented  Micro  Mono-Filament  technology,  which  generates  a  passive  electronic  field  to  create  beneficial  visual  and  sonic  effects  on  the  AC  current.  Using  our  MMF  technology in a loading application prevents time delay  and  distortion  of  the  transmitted  signal,  making  the  AC  current  that  much  closer  to  the  desired  “distortionless  condition”.  The  sensory  results:  an  improvement  in  the  overtones  and  pacing of the music, as well as a lower noise floor and a greater sharpness in the upper frequencies, depth and focus of visual qualities.Nordost’s    QKOIL,    or    QK1,    is    housed    in    a    mechanically    tuned    carbon-fiber    body    and    equipped with either a gold-plated US (NEMA) or EU (Schuko) plug. It is compatible with voltages from  110V  to  240V,  and  can  be  used  with  a  Schuko/AUS  or  Schuko/UK  adaptor  if  required.  Plug  the  QKOIL  into  any  spare  socket  on  your system’s  AC  Line  and  experience  first-hand  the  surprising, yet indisputable, effect it will have on your A/V components.Like  other  QRT  products,  the  benefits  of  the  QKOIL  are  cumulative  and  QK1s  are  even  more  impressive  when  applied  collectively.  It  can  be  used as a stand-alone product or to complement a full QRT system.
