Adjustment and tuning
Crossing over with main loudspeakers
The Sopranino is designed for reproduction of very high
frequency range of music. The Sopranino is equipped with a
carefully designed filter to keep out the unwanted low
frequency signals from entering the devices.
The crossover switch is preset to the following crossover
frequency
Matching the main loudspeakers
The Sopranino is designed with a nominal sensitivity 90dB at
2.82V input. It is compatible with most recently developed
high-resolution loudspeaker system. In case your speakers
are of lower sensitivity, bookshelf monitors for example. It is
advised to switch the GAIN switch to -3dB position for
matching. After extensive system verification and
consideration regarding characteristics of our electrostatic
tweeter, we recommended matching your main system by the
concept of spectral energy instead of sensitivity. If a system
demands more high frequency energy, you may lower the
crossover frequency (more music power into Sopranino). If a
system is overloaded with high frequency energy, it is
advised to raise the crossover frequency (fewer music power
into Sopranino).
