DSP Features
The KW Series features advanced DSP (digital signal processing) circuitry that performs many functions. Some functions are set at the design/
production level and are not user accessible. These functions include crossovers, time alignment, limiting and protection, thermal management
and a number of proprietary features. QSC has designed exclusive DSP functions that greatly enhance the capabilities and performance of the
KW Series systems.
Proprietary DSP Functions
Excursion Limiting: In addition to signal limiting to protect the amplifier and transducers from overload, the KW Series utilizes a proprietary limiter
that prevents woofer over-excursion. Over-excursion occurs when a voltage presented to the woofer causes the cone to physically travel too far. This
builds up excessive heat, stresses the moving parts of the woofer, produces audible artifacts and distortion and reduces the woofer’s lifespan. The
proprietary algorithm contained in Excursion Limiting prevents over-excursion. Voltages that will harm the woofer through over-excursion are reduced
enough to prevent over-excursion without any audible compression, limiting or loss.
DEEP™: Taking advantage of the Excursion Limiter, the DEEP™ (Digital Extension and Excursion Processing) algorithm functions as a highly musical
and non-distorting low-frequency EQ circuit. More on the DEEP function is available in the EQ section of this manual.
Intrinsic Correction™: Introduced on QSC Concert/Touring products, Intrinsic Correction is a proprietary process and set of signal processing
algorithms that address correctable characteristics of transducers and waveguides. The net result is that any KW Series system will present
extraordinarily even and consistent energy throughout the physical listening area of the loudspeaker, resulting in a very musical, acoustically
transparent system.
DSP User Functions
Low-frequency EQ
On the KW122, KW152 and KW153, there are three low-frequency settings. From the factory, the switch
is set to NORM. This means that the loudspeaker system is producing a normal low-frequency signal
through the woofer. This is the standard setting for most applications.
When using one of the top boxes with a subwoofer, the switch should be moved to the EXT SUB
position to engage the 100 Hz high-pass filter. It is also recommended that the 100 Hz high-pass filter be
engaged when using the KW122 as a floor monitor to prevent excessive bass build up on the stage.
For extra low-frequency extension and low-end presence when using one of the top boxes without
a sub, move the switch to the DEEP™ setting. This will engage the proprietary DEEP™ algorithm,
providing increased low-frequency extension without causing distortion or woofer over-excursion.
On the KW181 there are two low-frequency settings. From the factory, the MODE switch is set to
NORMAL. This means that the subwoofer system is producing a minimally EQ’d low-frequency signal
through the woofer. This is the standard setting for most applications.
For extra low-frequency extension and low-end presence, move the switch to the DEEP™ setting. This
will engage the proprietary DEEP algorithm, providing increased low-frequency extension without
causing distortion or woofer over-excursion.
