6
When only one amp is used, leave the ranking to 1.
If you use several amplifiers, rank them from 1 to their number.
When they will be powered ON in Auto-Power mode by receiving a signal, they will
start in the order of the rank they have, each after the previous one (few 100 millisec
later), avoiding the power surges to add-up at the breaker level.
To adjust the rank of each amp, when it is powered off, press the right key until the
ONRank adjustment is displayed. Change the rank by pressing the left key.
Other display
An input sensitivity adjustment is provided on the back panel of the amplifier.
To read the attenuation introduced by this adjustment (in dB), press once the right
front panel key. The attenuation will be displayed for 10 seconds.
When pressed twice, the front panel right key will display on front panel the output
circuit temperature, again for 10 seconds.
6 – SOUND QUALITY OPTIMIZATION
- Warm-up sonic effect.
If the power amplifier has been powered off for some time, the optimum sound
quality is only reached after several minutes. The critical circuits have to warm up to
55 degrees Celsius (+131 degrees Fahrenheit). When the amplifier has
been used recently, the optimum is reached after only 10 to 15 minutes.
- Speaker polarity.
Even if you have a phase inverter on your preamplifier (as on the GOLDMUND
MIMESIS 2 or MIMESIS 22), and even if you have carefully selected the proper line
phase (see in next paragraph), there is a possibility to again increase the sonic
quality of your speakers by reverting the polarity of the speaker cable amp
termination. But since the line phase and the speaker polarity interfere to each other,
you have to experiment carefully all the combinations before picking the right one.
If your preamp has an absolute phase inverter, this will interfere too. If it has not,
don't forget the result will depend of the source, most of the record and CD being
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
position, using a plug adapter.
