ATT1: Adjusts the level difference between LR and LsRs.
ATT2: Adjusts the level difference between C and Bs.
AMP: Corrects the LFE channel level.
HPF1–3: Cut the low range so that the speakers' supporting frequency ranges will not interfere with the
subwoofer signals.
HPF1–2: Cut the high range so that the subwoofer's supporting frequency ranges will not interfere with
other speakers' signals.
Tip: If you select 3-1 Monitor Matrix mode, use Presets 1 or 2 to establish an appropriate
monitoring environment.
You can set the Bass Management parameters in the following ranges:
HPF 1, 2, 3
LPF1
LPF2
ATT 1 & 2
AMP
The HPF 1, 2, 3, and LPF 1 & 2 values indicate a cut-off frequency and a filter response. For example,
"80-12" means a cutoff frequency of 80 Hz and a filter response of –12 dB/octave.
"L" means Linkwitz filter. Other filters are Butterworth.
