Packed with a powerful 1000 watt amplifier, a tough yet professional looking exterior, and some really flexible input and output mixing capabilities, the K12 from QSC stands out as a great option in the active loudspeaker market. Since powered speakers get used in many different kinds of ways, the K12 has been equipped to adapt to any situation.
You can use the K12 as a stand-alone PA system, without the need for an external mixer. Simply attach a microphone directly into its XLR combo input, and if needed, attach a second sound source to the other XLR combo input, and a third source (such as an MP3 player) to the RCA stereo input. There are two gain knobs that you can use to balance the mix, and a dedicated XLR output that outputs the mixed signal to a second K12 or any other active loudspeaker. For more involved professional installations, there are designated suspension points and kits available, and a Euroblock connector to remotely control the gain.
The back panel features a couple of easy-to-use switches that allow you to accentuate a person's speaking voice, or to add depth to the bass in music. Don't let the simplicity of the controls fool you; extensive digital signal processing is going on under the hood of the K12 that help it achieve its amazing sound quality. There's even a tilting feature in its standard 35mm pole mounting socket that enables you to point the K12 down toward the audience, so they can fully experience and appreciate your program material. If you're looking for a reliable powered speaker that's filled with useful functions and supplies great sound, look no further than the QSC K12.

Comments about QSC K12 12" 2-Way 1000 Watt Powered Speaker:
I bought the K12s to use for smaller gigs for my mobile Dj service, but after using them I think I am going to use them on most gigs and maybe only bring out my large mains for bigger venues. I am very impressed with the sound quality and loudness. The "Deep " setting is great for dance songs where you want a little more bass but don't want bring a sub. Great Speaker and with the B&H Stand And cable Deal I also got a great buy! Thanks again B&H for another Great Shopping Experience!

This speaker is really amazing. It's got loads of power and provides more low end than you'd expect from a 12" speaker due to QSC's 'DEEP' technology. I would definitely recommend this product.
