Description
F13
Channels A and B
parallel for 4
Ω
sub-
woofer; channels C
and D separate full
range
This is similar to F2, with these additions:
• Channels A and B are parallel, with a 48 dB/octave Butter-
worth low-pass filter at 80 Hz. The signal is summed from
inputs 1 and 2.
• Channels C and D are separate, suitable for stereo mains, with
48 dB/octave Butterworth high-pass filters at 80 Hz, which
perfectly complements the subwoofer filtering in A and B.
Channel C’s signal is from input 1 and D’s is from input 2.
These parameters are only a starting point; you can alter any of
them and save the configuration into a user preset.
F14
Channels A and B
bridged, full range;
channels C and D
bridged, full range
This is similar to F6, with these additions:
• Input 1 goes to the bridged channels A and B; Input 2 goes to
the bridged channels C and D.
These parameters are only a starting point; you can alter any of
them and save the configuration into a user preset.
F15
Single bi-amp
mode: Channels A
and B bridged for
4–8
Ω
LF; channels
C and D bridged
for 4–8
Ω
HF
This is similar to F6, with these additions:
• Input 1 goes to the bridged channels A and B, with a 48 dB/
octave Butterworth low-pass filter at 1.5 kHz.
• Input 2 goes to the bridged channels C and D, with a 48 dB/
octave Butterworth high-pass filter at 1.5 kHz.
These parameters are only a starting point; you can alter any of
them and save the configuration into a user preset.
F16
Single bi-amp
mode: Channels A
and B parallel for
2–4
Ω
LF; channels
C and D parallel for
2–4
Ω
HF
This is similar to F4, with these additions:
• Channels A and B are parallel, with a 48 dB/octave Butter-
worth low-pass filter at 1.5 kHz. The signal source is Input 1.
• Channels C and D are parallel, with a 48 dB/octave Butter-
worth high-pass filter at 1.5 kHz. The signal source is Input 2.
These parameters are only a starting point; you can alter any of
them and save the configuration into a user preset.
