FIR
FILTERING AND DESIGN
FIR filtering is a powerful and advanced feature of the 2x4 HD. It allows construction of complex arbitrary
equalization and crossover filters with independent control of amplitude and phase. The parameters of each FIR
filter are set in the
FIR
settings window:
Browse
Opens a file browser to select a file containing FIR filter coefficients. (See
Filter file format
below).
Unload FIR
Deletes the currently loaded filter from the display and from the DSP memory.
Send to DSP
Writes the currently loaded filter into the DSP memory.
BYPASS
Disables the FIR filter. The filter is disabled when the button is "lit."
File Mode / Manual Mode
In File Mode, the window displays the
Browse
and
Unload
FIR buttons as shown above. In
Manual Mode, the display changes to allow direct text entry of the FIR filter coefficients, as
shown below. The coefficients can be pasted into the window from a text editor.
