Control4 CORE 3 Controller (C4-CORE3)

The Control4 CORE 3 Controller is designed to be the direct replacement for the EA3 Controller. CORE 3 is the perfect fusion of multi-room, high resolution audio and smart installment automation for mid-size projects.

Powered by a next-generation multi-core processor, CORE 3 delivers a new level of speed and performance for instantaneous, interactive on-screen access to all the systems on the job. A built-in music server with three audio outputs delivers high-resolution audio throughout the your customer’s space from their local music library, popular streaming music services, and AirPlay-enabled devices using native Control4 ShairBridge technology.

CORE 3 includes a variety of I/O to automate audio and video, lighting, climate control, door locks, and other devices controlled by IP, infrared (IR), serial, and ZigBee. With PoE+ for power, a port for Ethernet out, and its optional mounting bracket, the compact form factor of CORE 3 makes it easy to install behind any TV or projector.

OvrC Pro remote management is built-in, giving you access to the entire network of IP devices, including third-party products. OvrC delivers enhanced troubleshooting capabilities and diagnostic data that makes remote support easy, eliminating unnecessary truck rolls and enabling you to streamline your business and tackle more jobs – all from the OvrC web or mobile app.

New DACs (digital audio converters) and additional audio outputs put the Control4 series of CORE Controllers at the center of our high-resolution audio platform: Ryff. And with OvrC Pro built-in, CORE will be the foundation for networking monitoring and management, remote connections and troubleshooting. This unique feature lets you improve your customer service, streamline your business, and have more control.



The controller is the brain of your smart home. It manages your home automation system, allowing the electronic devices in your home to work together—from lighting and security, to music and video, and pretty much anything else in between. No matter the size of your home, whether you’re automating a single room or a sprawling mansion, Control4 controllers are capable of powering your entire home automation system.
