DESCRIPTION
The models of the "OPERA D" series use cutting edge digital amplifiers of the DIGIPRO
series, providing three different powers - 200W, 400W, and 600W - to meet the
requirements of any kind of application.
These highly efficient amplifiers provide high power with limited weight and dimension.
OPERA 210D
Thanks to the low power dissipated, the cooling of the amplifier module does not require a
fan.
The OPERA 210D bi-amped active speaker is
equipped with a DIGIPRO amplifier delivering 150W
The digital preamplifier with DSP (Digital Signal Processing) controls the audio crossover
RMS for the bass section and 50W RMS for the high
