It packs built-in WaveDynamics DSP loudspeaker management into a 2U 19-inch chassis and accepts an optional Dante\/AES67 card. It is built to drive low-impedance installed loudspeakers in gyms, houses of worship, event venues, hotels and corporate spaces.\u003c\/p\u003e\u003ch2\u003eHow does the AUDAC SMQ750 work?\u003c\/h2\u003e\u003cp\u003eEach channel takes a balanced line feed on XLR or 3-pin terminal block, with link-through outputs for sending the same source to more amplifiers. The WaveDynamics DSP applies loudspeaker presets, EQ, crossovers and a configurable limiter before the Class-D output stage. Setup runs from the front-panel 2.5-inch LCD, and presets can be loaded from USB. AUDAC publishes a library of presets for its own speakers and set solutions, so an AUDAC system can be tuned by loading a file instead of measuring from scratch.\u003c\/p\u003e\u003cp\u003eOutputs are on Speakon-compatible and terminal block connectors. Pairs of channels can be bridged for 1500 W into a single 8 Ω speaker, which is how a quad amp drives two tops plus a bridged subwoofer. The switching power supply runs on 115–240 V AC, each channel has its own auto-standby, and cooling is by a temperature-controlled fan. RS232 control and TouchLink compatibility allow integration with control systems, and installing the \u003ca href=\"\/products\/audac-adc-ani44xt-dante-network-interface-module-for-use-with-smq-pmq-sma-vexo-active-loudspeakers\"\u003eANI44XT\u003c\/a\u003e card puts the amplifier on a Dante network.\u003c\/p\u003e\u003cp\u003eThis is a low-impedance amplifier.
