Dynacord Powersub 312

DYNACORD 12" Aktiv sub 2 x 250/800Watt 

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 unfavourable 

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 lacquers, 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.
