21
With
OUTPUT:
set to
PRE-EMPH
, the output of the 261 will follow the
pre-emphasis curve below the HF limiting threshold, and then level-
off at the limiter ceiling value at frequencies above the pre-emphasis
turnover point. Use this setting only if pre-emphasis is turned off in
the stereo-gen or exciter.
CAUTION:
Be aware that double pre-emphasis will result if the
261 is set as shown above,
and
the stereo generator or FM exciter
imparts transmission pre-emphasis as well. This is a condition to be
avoided like the proverbial plague.
