Operating Controls

Your Deﬁnitive Technology ProSub subwoofer is equipped with a full complement of operating controls to ensure complete ﬂexibility and maximum performance in any installation. Most of them basically are the “set and forget” type, although occasionally certain controls will require minor adjustments.

Gain Control

On the back panel of your subwoofer is a gain (volume) control. This control is used to raise or lower the output level of your subwoofer in relation to the other speakers in your system.

Low Pass Filter

Your subwoofer’s back panel features a continuously variable low pass ﬁlter. This ﬁlter is continuously variable between 40 and 150 Hz. This low pass ﬁlter control is used to obtain the optimum transition between the subwoofer and your main speakers. This control should be set by ear for best performance in your room. Set it to where it sounds best to you. If you are running your main speakers full range, we would generally recommend setting the low pass ﬁlter fairly low (40-70 Hz). If you are

connecting your ProSub using the the LFE in, turn the low pass ﬁlter all the way up in order to get optimal impedence matching. When using the

ProSub with Deﬁnitive ProMonitors, please consult the instruction manual section “Using the ProSub with Deﬁnitive ProMonitors.”

Powering Up Your Subwoofer

Your subwoofer contains a built-in, active powered subwoofer section as well as an electronic crossover and so each subwoofer must be plugged into an electrical socket of the appropriate voltage (as indicated on the back of your unit) using the plug on the end of the black cord attached to the electronics module on the back of the loudspeaker. The subwoofer has a special circuit which automatically turns the powered subwoofer section on when a signal is fed to the loudspeaker and does not require an on-off switch. The red LED on the back panel will light up when a signal is sensed and the ampliﬁer turns on. It will automatically turn off a little while after the signal is discontinued.

The ProSub has a special circuit which automatically turns the pow- ered subwoofer section on when a signal is fed to the loudspeaker and does not require an on/off switch. We suggest plugging the ProSub into a circuit which is on all the time and not into a switched outlet. When the ProSub is plugged into a circuit and receives AC current, initially you will hear a relatively loud pop which is completely normal as the system ﬁrst activates itself to stand-by mode. Then, when a program signal is fed to the speaker it will fully activate itself with a lower level pop which is normal. If you unplug the speaker or turn off the AC current going to it,
