28. ull range loudspeakers are set to approximately OdB Final system adjustments should be made within the range of adjustment marked NORMAL The range below 4 dB should not be used for normal program levels as the input headroom could be exceeded but can be used for testing at reduced levels If the input signal is extraordinarily strong it may be required to adjust the gain control in the range below 4dB A better solution might be to reduce the input signal strength to the powered loudspeaker s The range above 4dB should not be used for normal program levels as the loudspeaker may be more easily driven into clipping distortion due to overdriving the amplifier If the input signal is extremely weak it may be required to adjust the gain control s into the range above 4dB A better solution would be to increase the input signal strength to the powered loudspeaker system At the 20dB setting the signal is not completely cut off To fully cut off the signal fully reduce the input signal to the powered loudspeaker s Subwoofer Gain Notes Scenario One input signal only to the subwoofer one full range loudspeaker for each subwoofer The HPR loudspeakers are designed to be used as a system typically using one subwoofer for each full range loudspeaker If the subwoofer and the full range loudspeaker have their Gain controls set to OdB the tonal bal ance will be correct or very close to correct Scenario Two input L R si
