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.
Together these ensure that even when the most extreme demands are placed upon the system under the most unfavorable conditions, the PowerSub 312 continues to operate flawlessly. The use of „Class D Digital Technology" ensures that there is considerably less power dissipation than in normal Class AB designs. The thermal load on the components is therefore markedly reduced. The enclosure is coated with 2K lacquer, extremely scratch-resistant and proof against rough handling during transportation. A robust powder-coated steel grille protects the DYNACORD DND 12S400 woofer against mechanical damage. All the control elements are recessed to provide optimal protection of the PowerSub 312’s most sensitive parts even during transportation. For greater carrying comfort, the enclosure is furnished with two sturdy handles, whilst an integrated treaded pole adaptor saves space on stage by allowing you to pole-mount a satellite on top of the subwoofer.
