2. LOCAL CONTROLS AND CONNECTIONS
The 2 DIGIPRO G4 ampliers can
supply up to 3200 W RMS.
The block diagram of electronics of
VIO-L212 is illustrated in the next
page.
The two main sections, present at the
rear of the module, and protected by
the specic rain covers (not shown
here) are:
• CONNECTIONS AND CONTROL
• POWER SUPPLY
The CONNECTIONS AND CONTROL
section uses a DSP that controls,
among others, the output signal FIR
ltering.
The POWER SUPPLY section uses a
PFC which improves its efciency and
protects the amplication section
from undesired oscillations of the
input power supply.
FIR FILTERING
Sound equalization is controlled by a
32-bit DSP.
The implemented FIR lters minimize
the phase distortion of the equalized
signal. For more equalization informa-
tion, please refer to paragraph: “DSP
PRESET PARAMETERS”.
PFC
The power factor correction (PFC)
reduces the out of phase condition
between current and voltage supplied to
the amplier. Within a certain range the
input power supply is ideal, regardless
of small variations in the power supply
before the system. For more information
concerning power supply suggestions,
please refer to section: “LINE-ARRAY
ASSEMBLY AND CONNECTIONS”.
