Configuration

• 

 The 

Speaker Preset

 menu enables a set of speaker 

parameters to be adjusted, and preset configurations to be 
created. 

•   Speaker Presets can be simply applied to the selected 

amplifier output or imported, chosen from a library, exported 
or cleared. The preset configurations can include any or all of 
the parameters described in Section 5.3.4 and can be locked 
to prevent inadvertent modification. 

Diagrams

 

4i

 to 

4k 

illustrate the application of speaker presets.

  

Speaker Preset

 data provided by third parties for use with 

specific speakers can be imported and applied to amplifier 
outputs. To import speaker preset parameters follow the steps 
described below and illustrated in the diagrams. 

 

 

 1.  Select either the 

IMPORT PRESET FROM FILE

 or 

SELECT PRESET FROM LIBRARY 

option from the 

Speaker Preset

 menu.  If no import option is visible, 

select 

CLEAR

 to delete any existing speaker preset 

data.

Note: The SELECT PRESET FROM LIBRARY option will be unavailable if 
no speaker preset libraries have been created. Speaker preset library 
creation and management is described in Section 5.3.5.

 

 

2.  Select the appropriate ‘.zcp’ format speaker preset 

data file to import from either a Library or a computer 
folder. The preset data will be applied to the selected 
amplifier output as soon as the file import is complete. 

 

 

3.  If the Speaker Preset data requires modification it can 

be customized by selecting the CUSTOMIZE PRESET 
option.

Note: If an imported Speaker Preset data file includes locked 
parameters, they will be unavailable for modification.

5.3.4 Speaker Preset Menu Parameters

• 

 The 

Crossover & Gain

 preset menu enables high or low-

pass crossover filters and gain adjustment to be applied to 
individual amplifier outputs.  

 •  

 The 

Speaker EQ

 preset menu enables parametric equalization 

to be applied to individual amplifier outputs.

• 

 The 

FIR

 preset menu enables FIR (Finite Impulse Response) 

based equalization filter coefficients generated by external 
speaker measurement software to be imported and applied to 
individual amplifier outputs.

Note: FIR coefficient files in either .csv or .txt format can be imported.

• 

 The 

Driver Alignment

 preset menu enables delay to be 

applied to individual amplifier outputs.
