NEW! DYNACORD presents the new PowerSub 312 active subwoofer

Straubing, February 2008 Boasting an integrated three-channel power amplifier with a total output of 1300W, the PowerSub 312 active 12" subwoofer was specially designed to allow the swift and simple creation of a subwoofer satellite system. Two passive satellite loudspeaker systems (e.g. DYNACORD D8) are connected to the PS312 via Speakon outputs. 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. The "Sub Level" knob allows you to adjust the output of the PowerSub 312 within the range -∞dB to +10dB.
The integrated lightweight 800W  +  2 x 250W digital power amplifier is perfectly attuned in every respect to the integrated DYNACORD DND 12S400 woofer, maximizing dynamic range and audio quality while ensuring the woofer is invariably driven within its optimum working range. To provide further assurance that these operating limits are respected, performance is supervised by additional protective circuitry including voice coil protection, DC/HF protection, audio limiters, back EMF protection, and thermal protection. Together, these ensure that the PowerSub 312 continues to operate flawlessly—even in the most demanding or unfavorable conditions. The use of "Class D Digital Technology" ensures considerably less power dissipation than normal Class AB operation; thermal load on the components is therefore markedly reduced.
The robust multiplex enclosure is coated with 2K lacquer, an extremely scratch-resistant defense against rough handling during transportation and use. A robust powder-coated steel grille protects the DYNACORD DND 12S400 woofer from mechanical damage, and all the control elements are recessed.
