CPL function
The CPL (Coupling) function compensates for coupling effects
between the cabinets of an array. CPL begins gradually around
1 kHz, with the maximum attenuation below 400 Hz. As coupling
effects increase with the length of the line array, the CPL function
can be set to dB attenuation values between 0 and –9. With
higher attenuation values the corner frequency of the filter shifts
towards lower values.
Positive CPL values create an adjustable low frequency boost (0 to
+5 dB) and can be set when the system is used in full range mode
without subwoofers.
Note: Make sure that all cabinets within the line array are
operated with the same CPL setting.
