FIR FILTERS
Finite Impulse Response (FIR) filters are used in the signal processing of the cabinets. FIR is a type of digital filter with
linear phase characteristics. This frees system designers from the constraints of phase anomalies associated with
analogue filters or their digital versions (IIR, Infinite Impulse Response). When properly used, FIR filtering can audibly
improve a system’s impulse response and reduce crossover interference.
CONFIGURING THE CABINET DSP OPTIONS
On the back pannel of the cabinet you will find the digital control area. From the compact joystick located below the
screen you are able to configure the Basic adjustment functions of the internal DSP. Just move the joystick to select
the icons on the left of the screen. You can enter into the following functions:
Please note that you must apply the desired configuration in each one cabinet and requires electrical power to work.
If changes are not made the display will automatically dim to avoid unnecessary light in situations where light is not
wanted. To re-activate the light simply press the joystick.
