AV receivers are the central hub of home theater systems, orchestrating audio and video signals for an immersive entertainment experience. One commonly found feature on AV receivers is an infrared (IR) input. While often overlooked, the IR input plays a crucial role in enhancing the control and functionality of the AV receiver. In this article, we will explore the purpose of an infrared input on an AV receiver and how it enables seamless control in your home theater setup.
Understanding Infrared (IR) Control: Infrared control is a widely used method for remotely operating audiovisual devices. It utilizes infrared light signals to transmit commands between a remote control and the controlled devices. Most remote controls, including those that accompany AV receivers, use IR technology to send signals that instruct the receiver to perform various functions, such as changing inputs, adjusting volume, or switching between audio modes.
The Purpose of an Infrared Input on an AV Receiver:
- Centralized Control: AV receivers often serve as the command center for multiple audio and video devices, such as Blu-ray players, gaming consoles, and cable boxes. The IR input on an AV receiver allows you to consolidate control by connecting external IR emitters or extending the receiver’s built-in IR sensor. This centralizes the control of your entire home theater system through the AV receiver, streamlining your interaction with multiple devices.
- Remote Control Extender: The IR input on an AV receiver acts as a remote control extender, ensuring that commands from your remote control can reach devices that may be hidden or out of direct line-of-sight. By connecting an external IR emitter to the IR input, you can place the emitter in a visible location near your AV receiver, allowing it to transmit the IR signals to hidden devices in a cabinet or equipment rack.
- Overcoming Line-of-Sight Limitations: Infrared signals require a clear line of sight between the remote control and the device being controlled. However, the IR input on an AV receiver enables you to position the receiver in a more accessible or unobstructed location. This allows you to control devices without the need for direct line-of-sight, as the AV receiver acts as a relay for the IR signals, transmitting them to the intended devices via the connected IR emitters.
- Flexibility in Device Placement: The presence of an IR input grants you greater flexibility in the placement of your audiovisual devices. Instead of arranging devices solely based on line-of-sight considerations, you can position them in a way that maximizes functionality and aesthetics. The IR input and associated IR emitters allow you to control devices even when they are located inside closed cabinets or placed in less visible areas of your home theater setup.
- Enhanced User Experience: By utilizing the IR input on an AV receiver, you can enjoy a more seamless and intuitive user experience. Controlling multiple devices through a single remote control and having the flexibility to place devices in more convenient locations enhances convenience and eliminates the need for manual interaction with each individual component. This simplifies operation and creates a more immersive entertainment environment.
Conclusion: The infrared (IR) input on an AV receiver serves a crucial purpose in enhancing the control and functionality of your home theater system. By enabling centralized control, acting as a remote control extender, overcoming line-of-sight limitations, and providing flexibility in device placement, the IR input ensures a seamless and convenient user experience. Take advantage of this often-underappreciated feature to simplify control and unlock the full potential of your AV receiver and audiovisual devices.
