OVATION PH 8.3

B asic operat ion

2.6.2 Special playback settings

With the MODE selection key (3) the PH 8.3 may be set to
mono mode ("MONO" shown in the display) or, by pressing the
button several times, to phase rotation by 180° in STEREO
(display: "stereo-") or MONO ("mono-").

For  playback  of  older  mono  records  the  setting  of  the  PH  8.3
to  MONO  can  be  very  helpful,  as  the  groove  noise  (present  in
stereo)  is  suppressed  to  a  certain  degree.  If,  in  addition,  a
record  has  been  recorded  out  of  phase,  the  PH  8.3  can  easily
correct  this:  In  this  case,  choose  one  of  the  following  set

-

tings: "stereo-" or "mono".
