Additional information


If you’re looking for whole house voice controlled music, routines, paging, intercom and smart devices, look no further than the NERO-VOX. Super easy installation, perfect for upgrading traditional in-wall volume control using existing pre-wire.

The NERO VOX from OSD Audio is an in-wall amplifier that harnesses the capabilities of Alexa and the Echo Dot and allows you to stream music from room to room without switches, dials, or touchscreens. With its six-inch square flush- mount faceplate, this amplifier provides 40W of power to a pair of in-ceiling or in-wall speakers so you can experience remarkably better sound quality than the Dot’s internal speakers and play what you want, when you want, all with hands-free voice control, or use the exposed control buttons on the top plate of the Echo Dot.

An Elegant Multi-Room Audio Solution
The NERO VOX amplifier supplies 40W of power (20Wx2) and connects to in-ceiling, in-wall, or bookshelf speakers with cables and wires hidden from view. Similar to installing in-wall speakers, the NERO VOX is flush mounted and installs directly into a drywall surface with dog ear clips. The Echo Dot fits securely inside the docking station enclosure, the hidden amp and paintable cover trim blend into any décor. The audio/input/output and power wall plate, which is typically installed near a power outlet, includes dual RCA inputs to add a subwoofer to your sound system as well as a 3.5mm aux input to connect the Echo to your TV.

The NERO VOX in-wall amp transforms the little Echo Dot into a high-performance audio system and unleashes the power of Alexa. You’ll have voice-controlled access to your music library and Amazon Music as well as services like Spotify, iHeartRadio, Pandora, and TuneIn. Add the NERO VOX to the living room, kitchen, den, or any room with speakers and ask Alexa to play whatever you’re in the mood to hear either in a selected zone or throughout the house. [Please note that the Nero Vox in-wall amp is designed to work with the Echo Dot Gen 3 and is not compatible with previous versions.]
