Operating ControlsYour Definitive Technology ProSub subwoofer is equipped with a fullcomplement of operating controls to ensure complete flexibility and maxi-mum performance in any installation. Most of them basically are the "setand forget" type, although occasionally certain controls will require minoradjustments.Gain ControlOn the side of your subwoofer is a gain (volume) control. This control isused to raise or lower the output level of your subwoofer in relation to theother speakers in your system.Low Pass FilterYour subwoofer's back panel features a continuously variable low passfilter. This filter is continuously variable between 40 and 150 Hz. This lowpass filter control is used to obtain the optimum transition between the sub-woofer and your main speakers. This control should be set by ear for bestperformance in your room. Set it to where it sounds best to you. If you arerunning your main speakers full range, we would generally recommendsetting the low pass filter fairly low (40-70 Hz).

The subwoofer has aspecial circuit which automatically turns the powered subwoofer section onwhen a signal is fed to the loudspeaker and does not require an on-offswitch. The red LED on the back panel will light up when a signal issensed and the amplifier turns on. It will automatically tum off a littlewhile after the signal is discontinued.The ProSub has a special circuit which automatically turns the poweredsubwoofer section on when a signal is fed to the loudspeaker and does notrequire an on/off switch. We suggest plugging the ProSub into a circuitwhich is on all the time and not into a switched outlet. When the ProSub isplugged into a circuit and receives AC current, initially you may hear apop which is completely normal as the system first activates, itself tostand-by mode. Then, when a program signal is fed to the speaker you mayhear a pop which is normal. If you unplug the speaker or turn off the AC
