Lro (LFE & CEN Level Roll Off) This function parameter setting allows adjustment of the roll off
(crossover) from the LFE & CEN input received via the RCA line level connectors. This
parameter enables high frequencies to be filtered out above the displayed setting with a 24dB
slope from sources connected to these inputs. Most but not all AV decoders offer an adjustable
pre filtered output for the LFE content. Offering this fully adjustable setting for the LFE crossover
gives a more flexible use for this input and enables the user to make adjustments over a wider
frequency band and result in better integration possibilities. Selecting above 120hz results in the
“LFE bypass” circuit option. The LFE bypass circuit sets the crossover to 200hz and only gain is
adjustable. The adjustment range is from 20hz to 120hz & bypass, incremented in single digit Hz
steps. This highly accurate roll off adjustment enables precise matching of crossovers when
using a multiple subwoofer set-up.
H-L (High and Low Level Attenuation) This function parameter setting allows adjustment of the
gain from the inputs received via the Speakon and RCA line level left and right connectors. This
parameter enables adjustment of gain and thus sound pressure output produced in relation to the
input from sources connected to these inputs. The adjustment range is from –98 to 0
incremented in single dB digit steps. This highly accurate gain adjustment enables precise
matching of gains when using a multiple subwoofer set-up.
Hro (High Roll Off ) This function parameter setting allows adjustment of the roll off (crossover)
from the inputs received via the Speakon and RCA line level left and right connectors. This
parameter enables high frequencies to be filtered out above the displayed setting with a 24dB
slope from sources connected to these inputs. The adjustment range is from 20hz to 120hz
incremented in single hz digit steps. This highly accurate roll off adjustment enables precise
matching of crossovers when using a multiple subwoofer set-up.
LFE (LFE & CEN Level Attenuation) This function parameter setting allows adjustment of the
gain from the LFE & CEN input received via the RCA line level LFE & CEN connectos. This
parameter enables adjustment of gain and thus sound pressure output produced in relation to the
input from the LFE & CEN output of your AV amplifier. The adjustment range is from –98 to 0
incremented in single dB digit steps. This highly accurate gain adjustment enables precise
matching of gains when using a multiple subwoofer set-up.
