The QSC KSub is designed to endure the rigors of the road for years to come. Its cabinetry is constructed of premium-grade Baltic birch and finished with a chip and scratch-resistant textured paint. You’ll find the cast aluminum handles to be comfortable and ergonomic. And KSub’s 3 inch, heavy-duty, low-noise casters will make your load-in and load-out a breeze.
Rear Panel Features:
Set the MODE switch to NORMAL for no effect, or choose DEEP for additional bass extension. Flip the PHASE switch from NORMAL to REVERSE to solve phase cancellation issues in conically-challenged rooms or to better match the internal wiring of other speakers.
The LED switch selects which mode the front-mounted LED indicates. Choose from POWER to tell at a glance if the KSub is powered on; LIMIT to monitor when the clip limiter circuit has been engaged; or OFF for situations where you don’t want the LED to be illuminated at all.
A three-LED array on the rear panel indicates POWER, LIMIT or STANDBY (Auto-Standby mode kicks in after 5 minutes of inactivity). There’s also a Master GAIN control with LED to indicate when SIGNAL is present.
