Features

Power-over-Ethernet

There are two audio inputs, Audio over Ethernet (Dante) and Line input with RCA Connector. The power supply can be provided by an external 24V or a PoE PD module.

Digital Amplifier

The AMP-NAP-140C4 has 4 digital amplifiers ADI Maxim MAX98397, which can support 4 x 30W into 8ohm and 4 x 20W into 4 ohm load at THD+N = 1% (Need to use external 24V supply when total output power larger than 50W). 

Pre-Certified for Decoding

AMP-NAP-140C4 has been certified for decoding a wide range of audio formats: Dolby Atmos, DTS/DTS:X (including IMAX Enhanced), MPEG-H, MPEG-4 AAC, Sony 360RA and Auro3D.
