QSC KSUB Dual 12" Powered PA Subwoofer

The QSC KSub is a dual 12-inch, 4th order bandpass active subwoofer system featuring an all-new 1000 Watt QSC Class D power module outputting a remarkable 130 dB (peak). The KSub delivers low-frequency extension down to 44 Hz. Extensive DSP featuring Intrinsic Correction(TM) and DEEP(TM) provide for levels of total sonic performance that defy the system's size and weight while GuardRail(TM) protection, first introduced on the GSX Series amplifiers to protect both the amplifier module and your performance from unnatural and destructive clipping.

Combo XLR and 1/4" TRS inputs accept both Mic and Line Level input while a pair of direct outputs are also provided on each channel for additional output flexibility.

The rear-panel LF switch can be set to NORM, DEEP(TM) for an additional measure of bass extension without over-excursion or sonic degredation. The LED switch can be set to POWER, illuminating the front-mounted LED when the unit is powered on, OFF for applications where it is not desirable to illuminate the front LED, or LIMIT which indicates to the system operator that the clip limiter circuit has been engaged during operation.

The entire system is housed in a rugged birch enclosure with a professional appearance that is at home in any vertical or horizontal application. Ergonomic aluminum handles and four heavy-duty, low-noise casters complete the package for ease of transport and long term durability.

The KSub also features a unique threaded pole mounting system. Securing the threaded speaker pole (included) to the receptacle allows a speaker enclosure with a standard pole cup to mount securely and wobble-free above the subwoofer.

Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Euroblock connector. In an installed application, multiple K Series speakers can be "daisy-chained" for total gain control from a single remote pot.
