Qsc K12 Benutzeranleitung

The K 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 K Series systems.

Excursion Limiting: In addition to signal limiting to protect the amplifier and transducers from overload, the K 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

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 algo-
rithms that address correctable characteristics of transducers and waveguides. The net result is that any K 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.

On the K8, K10 and K12, 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 K10 or K12 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 KSub there are two low-frequency settings. From the factory, the switch is set to “NORM.” This means 
that the subwoofer system is producing a non-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.

On the K8, K10 and K12 there are two high-frequency settings. From the factory, the switch is set to “FLAT.” This 
means that the loudspeaker system is producing a flat response through the vocal band. This is the standard set-
ting for most applications.
