AV receivers have long been recognized as the central hub for audio and video processing in home entertainment systems. However, their capabilities extend beyond audio and video control. Many modern AV receivers feature advanced integration and control options that allow them to serve as a central command center for various devices, including lighting systems and other home automation devices. In this article, we will explore how an AV receiver can harness its control capabilities to seamlessly manage lighting and other devices in your home.
The Role of an AV Receiver in Device Control:
- Integrated Control Platforms: AV receivers often support integration with popular home automation platforms, such as Control4, Crestron, or RTI. These platforms provide a unified interface that allows you to control multiple devices, including lighting systems, HVAC systems, motorized shades, and more. By connecting your AV receiver to these platforms, you gain centralized control over an array of devices within your home.
- IR (Infrared) Control: Most AV receivers have built-in IR capabilities to receive and transmit infrared signals. This functionality allows them to control not only audio and video devices but also other IR-controlled devices, including many lighting systems. By programming the AV receiver with the appropriate IR codes, you can use your receiver’s remote control or a dedicated home automation remote to command both your AV system and your lighting system simultaneously.
- RS-232 and IP Control: AV receivers often support advanced control protocols, such as RS-232 and IP control, which enable communication with other devices over a wired or wireless network. Through these protocols, AV receivers can establish direct communication and control with compatible lighting systems and other devices. This allows for more advanced automation scenarios and integration with home control systems.
- Trigger Outputs: Some AV receivers feature trigger outputs, which are low-voltage connections that can send control signals to other devices when certain events occur. These triggers can be used to activate or deactivate external devices, such as lighting systems, based on specific AV receiver operations. For example, when the AV receiver is turned on, a trigger output can activate the desired lighting scene in the room.
- HDMI-CEC (Consumer Electronics Control): HDMI-CEC is a feature that allows devices connected via HDMI to communicate and control each other. AV receivers with HDMI-CEC support can utilize this feature to control HDMI-connected devices, including some lighting systems. Through HDMI-CEC, the AV receiver can power on or off the connected devices, switch inputs, and control basic functions, all through a single remote control or the AV receiver’s user interface.
- Customizable Macros and Scenes: Many AV receivers provide the ability to create custom macros or scenes, which are predefined sequences of commands that can control multiple devices simultaneously. By programming macros or scenes, you can automate complex actions, such as turning on specific lights, adjusting audio settings, and starting playback—all with a single button press on your AV receiver’s remote or control interface.
Conclusion: The evolution of AV receivers has expanded their capabilities beyond audio and video control, enabling them to serve as a central command center for lighting systems and other devices in your home. Through integrated control platforms, IR control, RS-232 and IP control, trigger outputs, HDMI-CEC, and customizable macros, AV receivers can seamlessly integrate and control various devices, streamlining your home automation experience. By leveraging the control capabilities of your AV receiver, you can create a unified and convenient control system that enhances both your audiovisual enjoyment and the overall functionality of your home.
