AMPLIFIER
The integrated 170 Watt RMS Class D amplifier is a
highly linear construction. The DALI SUB C-8 D will
follow and render the required signal with an absolute
minimum of bias. Designed not only for continuous
power, but also for peak power, this subwoofer is able to
deliver 220 Watt Peak Power. This is very relevant when
it comes to both movie and music signals.
The switch mode power supply is part of the reason for
very low power consumption - only 0.4 Watt in stand-
by mode. And the amplifier displays an impressive
efficiency of 70%. In unison the high-efficiency amplifier
section and power supply construction generate an
absolute minimum of heat loss. For that reason you will
find no external heat sink on this subwoofer.
To improve sound reproduction in general, and to
ensure that this subwoofer can perform under difficult
circumstances, a limiter has been incorporated in
the amplifier section. The integrated limiter works in
two areas: It compares the input signal amplitude to
the potential output signal level, and it compares the
available supply voltage from the power supply to the
expected output signal. If any of these comparisons
show that there will be a problem then the limiter will cut
the signal in a soft manner and without affecting peak
power.
Fitted with controls for gain, cut-off frequency, and
phase, the DALI SUB C-8 D will adapt to any front
speaker and room acoustics. And with a choice of LFE
and LINE inputs it can be connected to almost any
amplifier, receiver or processor.
