RDL SF-NP40D Network to 40W Stereo Power Amplifier, Dante Converter

The Radio Design Labs SF-NP40D is an audio power amplifier that converts two Dante network audio channels to two 4 Ohm or 8 Ohms amplified outputs. Each output provides 20 watts into 8 ohms for a network digital audio level of 0 dBFS. Special software is not required to configure the module. A front-panel blue LED illuminates when the unit is powered from its included external 24 Vdc power supply. The module is equipped with both thermal and output short-circuit protection. The high-efficiency Class D output stages produce minimal heat for all levels of expected voice or music modulation. Valid synchronization to the Dante network is indicated by a green LED visible from the front of the unit.

The SF-NP40D is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured SYSFLEX® product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. The versatility of SYSFLEX® products adds enormous flexibility in the design and installation of professional A/V systems.
