It splits the incoming signal between the low and high frequency drivers at a crossover point of 4kHz, keeping each driver working within its intended range. If your existing crossover has failed or you are rebuilding a cabinet, this board gives you a straightforward like-for-like fit.\u003c\/p\u003e\n\u003cp\u003eWe supply this component as a direct match for the QTX QS12 cabinet (part 178.562UK), so it drops in without the need to work out compatibility yourself. Because it is a passive design, it runs off the amplified signal already reaching the cabinet and needs no separate power supply. That makes it a simple part to fit during a repair or a speaker build.\u003c\/p\u003e\n\u003cp\u003eThe board measures 25 x 140 x 115mm and weighs 0.11kg, so it sits neatly inside most standard cabinet enclosures. It handles a nominal 300W and works with an 8 Ohm load, matching common full-range PA and speaker setups. A crossover is sometimes called a crossover network or dividing network, and all three terms refer to the same job of routing frequencies to the correct drivers. Keep the wiring polarity correct when fitting to maintain proper phase between the drivers.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower handling : nominal\u003c\/td\u003e\n\u003ctd\u003e300W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrossover frequency\u003c\/td\u003e\n\u003ctd\u003e4kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eImpedance\u003c\/td\u003e\n\u003ctd\u003e8ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e25mm x 140mm x 115mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.11KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhich cabinet is this crossover for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt is intended as a replacement for the QTX QS12 cabinet, part number 178.562UK.
