PowerSub 312

POWERED SUBWOOFER

The PowerSub 312 powered 12“ subwoofer, which is equipped with an integrated three-channel Class D power amplifier with a total output of 1300 W / RMS, was specially conceived to permit the swift and simple creation of a subwoofer satellite system.

As satellites, two passive loudspeaker systems such as the DYNACORD

D 8 are needed. You only need to connect them to the Speakon out- puts provided for the purpose. The „X-Over“ switch offers a choice of three discrete frequencies for the crossover between the subwoofer and the satellites: 70 Hz, 100 Hz and 140 Hz, whilst the „Sub Level“ control allows you to adjust the output of the PowerSub 312 in the range from -8 dB to +10 dB. The PowerSub 312 is made from multiplex birch plywood and capable of withstan-

ding the toughest challenges during transportation as well as in use. The integrated lightweight 800 W +

2 x 250 W digital power amplifier is perfectly attuned in every respect to the integrated DYNACORD DND 12S400 woofer to maximize the dy- namic 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 pro- tection, 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, which is extremely scratch- resistant and proof against rough handling during transportation.

Arobust, powder-coated steel grille protects the woofer against mechanical damage. All the control elements are recessed to provide optimal protection of the Power- Sub 312’s most sensitive parts even during transportation. For greater carrying comfort, the enclosure is furnished with two sturdy handles, whilst an integrated threaded pole adaptor allows you to make optimal use of precious space on stage.
