It uses an energy-efficient switch-mode power section and a class-D amplifier circuit to deliver power on demand across four independent speaker outputs. Proprietary cool guide technology keeps the temperature stable for dependable operation, whether the unit sits in a permanent install or goes out on the road.\u003c\/p\u003e\n\u003cp\u003eYou can run the D4500 as a quad, stereo or 2.1 system, and each pair of output channels can be parallel switched or bridged. Channel A has a switchable 120Hz low-pass filter (LPF) for use with subwoofers, while channels C and D share a switchable stereo pair of 120Hz high-pass filters (HPF) to focus power in full-range cabs working as mid-tops alongside subs. The audio signal path is fully balanced, with four female XLR inputs and four Speakon-style SPK outputs.\u003c\/p\u003e\n\u003cp\u003eFull audio and power protection is built in, including a peak limiter to guard both the amplifier and the connected speakers. Input sensitivity is set at 0dB = 0.775Vrms, and the unit runs from a standard 220-240Vac IEC mains supply. For audio designers and sound engineers, the D-series is a flexible problem solver that adapts to a wide range of speaker configurations without taking up much rack space.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e220-240Vac, 50\/60Hz (IEC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModes\u003c\/td\u003e\n\u003ctd\u003e2 x Stereo, Parallel (mono), Bridge (mono)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput sensitivity\u003c\/td\u003e\n\u003ctd\u003e0dB = 0.775Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput connections\u003c\/td\u003e\n\u003ctd\u003e4 x XLR female\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSound output\u003c\/td\u003e\n\u003ctd\u003e4 x SPK connectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCrossover\u003c\/td\u003e\n\u003ctd\u003eInput A 120Hz LPF and C+D 120Hz HPF (all switchable)\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\u003eHow much power does the D4500 deliver?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt provides four channels at 500Wrms each.
