SOUND QUALITY OPTIMIZATION

WARM-UP SONIC EFFECT
When the amplifier has not been used recently it will take 10 to 15 minutes for the amplifier
to reached optimum operating temperature, as the circuits have to warm up to around +55
degrees Celsius.
SPEAKER POLARITY
Even if you have a phase inverter on your preamplifier and have carefully selected the
proper line phase (see next paragraph below), there is a possibility to further increase the
sonic quality of your speakers by reverting the polarity of the speaker cable amplifier
termination. Line phase and speaker polarity interfere with each other however. We
therefore advise careful experimentation with all the combinations in order to arrive at the
best solution for your installation.
If your preamplifier has an absolute phase inverter, this will interfere too. If it has not, don't
forget the result will depend on the source, as most records and CDs have been recorded
without care for the absolute phase. Be patient...
MAIN LINE PHASE INVERSION
To select the proper phase, you have to select, by trying, one of the two power cord
positions.
We recommend that you proceed carefully when trying this. You must do it in combination
with the speaker polarity and/or with absolute phase switching to be sure of the result.
