The PowerSub 312 active 12“ subwoofer, which is equipped with an integrated three-channel power amplifier with a total output of 1300W, was specially conceived to permit the swift and simple creation of a subwoofer satellite system, for which purpose all that is needed is to connect two passive (e.g. DYNACORD D8) loudspeaker systems to the Speakon outputs of the PowerSub 312. The „X-Over“ switch offers a choice of three discrete frequencies for the crossover between the subwoofer and the satellites: 70Hz, 100 Hz and 140 Hz, whilst the „Sub Level“ control allows you to adjust the output of the PowerSub 312 within the range -8dB to +10dB. The PowerSub 312 is made from multiplex birch plywood and capable of withstanding the toughest challenges during transportation as well as in use. The integrated lightweight 800W + 2 x 250W digital power amplifier is perfectly attuned in every respect to the integrated DYNACORD DND 12S400 woofer to maximize the dynamic range and audio quality and ensure that the woofer is invariably driven within its optimum working range. To provide further assurance that these operating limits are respected, the performance is supervised by additional protective circuitry such as voice coil protection, DC/HF protection, audio limiters, back EMF protection and thermal protection.
