At 15 watts RMS, the KB/A 15’s heavy-duty 8" speaker gets the job done! And for situations that require headphones, the KB/A 15 delivers. Two channels are provided, featuring 1/4” inputs, level controls, and two-band active equalization (Low, High). In addition, Channel One features a Bright switch. The front panel headphone jack automatically disables the internal speaker when connected. Special attention was given to make the KB/A 15 as compact and light as possible to maximize portability, yet provide a “big” sound. Go ahead...pick it up! At 14 lbs., it’s perfect for “on-the-go” projects. And the size? Well, let’s say it’ll fit just about anywhere. Like all of the KB/A Series, the KB/A 15 is built for the road. First, extremely tough black covering is provided along with heavy-duty corners. Second, a serious handle is available at the top of the unit. Third, heavy-duty rubber feet are provided to protect the bottom. This amp is for real. Check it out—it’s all there...sound, portability, roadworthy design. Also, with every KB/A series amplifier, you get Peavey’s excellent one-year warranty (check the warranty document at the end of the manual for full details), and the best in customer service from Peavey’s award-winning repair and service department.
