If you are not sure about the phase of every piece in your system, you
can establish correct absolute phase by careful listening. When the
system is in correct phase, transients will be noticeably cleaner and
more sharply defined. The effect is especially apparent on plucked string
sounds. A final warning-not all recordings are phase correct (including
some "audiophile" recordings), so listen to several before concluding
your investigation of absolute phase.
AC LINE POLARITY
Each piece of electronic equipment in your system is subject to minute
ac leakage currents to the chassis. Since the chassis of components in
a system are usually connected via the ground side of the interconnect
wires, these leakage currents are superimposed on the musical signals.
It is possible to minimize these current flows by carefully selecting the
way in which each component is plugged into the wall outlet. Because
tthe power cord on the SC-1 is not polarized, it can be plugged in two
ways. It will normally sound better in one orientation than in the other.
The same will be true of any electronic device in your system.
THE IMPORTANCE OF WIRES
Interconnect and speaker wires are an important element in your stereo
system. Interconnects are available which will permit a reference quality
system to blossom and fulfill its promise of musical reality. Others will
strangle the system to the point where it becomes no better than
average. To complicate matters, our experience suggests that the
choice of interconnects will be system dependent- those that are ranked
first on a given system may be a poor choice for a different system.
Consult your Sonographe dealer for recommendations for your specific
system.
TIP
Warm up the SC-1 before listening: The sonic performance of the SC-1
improves noticeably as the unit warms up. The midrange becomes more
lucid, the highs smoother, and the soundstage expands. The warm up
period can be expected to last several hours. Consequently, we recom-
mend that the SC-1 be left on at all times. The low power consumption
of the unit makes this practical.
