2.3.1. Controller settings
For acoustic adjustment the functions CUT, HFC and CPL can be

selected.

CUT circuit
Set to CUT, the cabinet low frequency level is reduced. The

cabinets are now configured for use with d&b active subwoofers.

HFC circuit
Selecting the HFC (High Frequency Compensation) circuit

compensates for loss of high frequency energy due to absorption

in air when loudspeakers are used to cover far field listening

positions.

The HFC circuit has two settings (HFC1, HFC2) for different

distance ranges the cabinets have to cover. The settings should be

used selectively, only for those cabinets covering the respective

distances, HFC1 for distances larger than 25 m (80 ft) and HFC2

for distances larger than 50 m (160 ft).

The compensation is adjusted for a typical relative humidity of

40 %. With lower humidity the absorption by air increases

therefore the distances where the respective HFC setting provides a

correct equalization are shorter than indicated above.

Using the HFC function provides the correct sound balance

between close and remote audience areas, whilst all amplifiers

driving the array can be fed with the same signal.

CPL circuit
The CPL (Coupling) circuit compensates for coupling effects

between the cabinets of an array. CPL begins gradually around

1 kHz, with the maximum attenuation below 200 Hz. As coupling

effects increase with the length of the line array, the CPL circuit 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.
