Pro Sound, No Guesswork

The JBL IRX115S powered subwoofer, the newest model in the IRX series of versatile, cost-conscious portable P.A.s, extends the low-frequency response of IRX systems down to a room-shaking 32 Hz. The 15” IRX115S draws from JBL’s top professional touring technologies to deliver superior sound without the guesswork, thanks to custom driver and amplifier designs; tuned, ported enclosure; and built-in crossover and polarity settings. It all adds up to an impressive 128 dB of deep, powerful bass, in a rugged, ultralight cabinet weighing just 65.3 pounds. The IRX Series offers legendary JBL fidelity, power and ease of use at a fraction of the price and size of comparable systems. The 8-inch IRX108BT and the 12-inch IRX112BT are fully loaded with features that make it easy to dial in incredible sound in an instant—from real-world EQ presets and dbx DriveRack automatic feedback suppression to Bluetooth streaming and one-touch ducking. Budget-conscious musicians, DJs, presenters and fitness instructors can count on versatile, full-featured JBL IRX Series portable P.A.s to deliver stunning sound, no matter their experience level.

Is there a built in limiter. Your docs say nothing about it, but I assume because there's a "Signal/Limit" light that you have inserted a limiter. But how do we know when it's engaged? Does the LED turn red?
