{"product_id":"rdl-sf-np40d","title":"RDL SF-NP40D – Dante 40 W Stereo Amplifier, US Cord","description":"\u003ch2\u003eWhat is the RDL SF-NP40D?\u003c\/h2\u003e\u003cp\u003eThe RDL SF-NP40D is a Dante network stereo power amplifier that converts two Dante channels to two amplified outputs. Each output delivers 20 W into 8 Ohms, or 15 W into 4 Ohms, for a network level of 0 dBFS. An external 24 Vdc power supply is included, and the SF-NP40D includes a North American power cord. It is a compact way to drive local loudspeakers in conference rooms, huddle spaces and classrooms from a Dante network.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/sf-np40d.jpg\" alt=\"RDL SF-NP40D Dante 40 W Stereo Amplifier, US Cord\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe SF-NP40D receives two Dante channels and converts them to two amplified outputs, switch-selectable for 4 Ohm or 8 Ohm loads. Special software is not required to configure the module, and it supports Dante sample rates of 44.1, 48, 88.2 and 96 kHz. THD+N is under 0.1% from 20 Hz to 20 kHz, with 0.015% typical at 1 kHz, and crosstalk is better than -75 dB. The high-efficiency Class D output stages produce minimal heat for expected voice and music program. Thermal and output short-circuit protection are built in. A blue front-panel LED lights when the amplifier is powered from its included 24 Vdc supply, and a green LED confirms Dante sync. The included supply accepts 100 to 240 Vac, 50\/60 Hz, through an IEC C14 inlet and outputs 24 Vdc at 2 A. RDL states that the SF-NP40D includes a North American cord and the SF-NP40DE excludes the power cord; see the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-sf-np40de\"\u003eRDL SF-NP40DE\u003c\/a\u003e if you need the other version.
