About the KS212C Cardioid Subwoofer The term Cardioid refers to the heart-shaped coverage pattern of an audio device. A cardioid microphone is designed to be most sensitive at the front (on-axis), and least sensitive at the rear (180 degrees off-axis). A Cardioid Subwoofer operates exactly the same way, and is loudest at the front and quietest at the rear.
Applications and Installation WARNING!: Before placing, installing or mounting any speaker product, inspect all hardware, cabinets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated component could significantly reduce the strength of the installation or placement. Any such condition severely reduces the safety of the installation and should be immediately corrected.
Pole-mounting Loudspeakers Over the KS212C The KS212C is equipped with two 35 mm M20 pole sockets, one on the top, and one on the side for polemounting a loudspeaker over the unit. Figure 5 shows a KS212C in a vertical orientation with a K.2 Series loudspeaker mounted above. Figure 6 shows a KS212C in a horizontal orientation with a K.2 Series loudspeaker mounted above. Use the table below to determine which poles you can use with the various K and K.
AC Mains Refer to Figure 7 AC Mains Disconnection Push in on the bottom of the power switch to turn the amplifier off. Unplug the AC cable from the power source.
