The box in fact is made in light multilayer wood, coated in PVC and the sides are in polypropylene. The speakers of “SUB D” H.E.T. series use multichannel digital power amplifiers of last generation DIGIPACK. These highly efficient amplifiers provide high power with limited weight and dimension. Thanks to the low power dissipated, the cooling of the amplifier module does not require a fan. The digital preamplifier with DSP (Digital Signal Processing) controls the audio crossover of the acoustic components, the frequency response, the limiter, and the phase alignment. The correct switch on of the amplifier is guaranteed by an initialization procedure; during this test stage the LEDs (“LIMITER” and “ON SIGNAL”), located on the amplifier module, stay on together for approx. 2 sec. At the end of the switch on procedure, on the amplifier module, the “ON SIGNAL” green LED flashes slowly, when there is signal absence. During normal operation the “ON SIGNAL” green LED serves as Vu-meter monitoring the audio level riproduced. The \"LIMITER\" red LED lights up to indicate that the internal limiter circuit has tripped to prevent amplifier distortion and protects the speakers against overloads. SUB D (H.E.T.) are active sub-woofers designed for medium to large size rooms; are made using “BAND PASS” so that high sound pressures can be achieved in compact dimensions. These speakers are designed to function in stereo and in mono modes. It is possible to set the frequency response and turning of phase (0 or 180 degrees). The output signals can be linked or controlled by X-OVER output. For easy use, installation and transport, all subwoofers are provided with 2 plastic handles on sides, and standard (D.36mm) pole mount plate on top of box. Balanced inputs at line level. Accept “XLR” sockets. The “XLR” connectors be used to send the input audio signal to another amplified speaker.\u003c\/p\u003e","brand":"DB Technologies","offers":[{"title":"Default Title","offer_id":48408315028,"sku":"859491","price":799.0,"currency_code":"INR","in_stock":true}],"url":"https:\/\/sg-2111.myshopify.com\/products\/dbtechnologies-sub-12-d-active-12-subwoofer","provider":"SG_2111","version":"1.0","type":"link"}
