As AV systems become more integrated and centralized, the need to control equipment from a distance—often from behind closed cabinet doors or across multiple rooms—has become essential. Devices like IR repeaters and RF extenders offer practical solutions for extending control signals without compromising on convenience or performance.

IR repeaters help relay signals from standard infrared remotes, while RF extenders enable wireless control over longer distances and through obstacles. Both tools play a crucial role in modern AV setups, especially in home theaters, boardrooms, and whole-home automation systems.

But to use these devices effectively, you must plan for them during the design phase. This means carefully routing control signal paths, ensuring compatibility with devices, and documenting these connections clearly in your AV diagram.

That is where XTEN-AV proves invaluable. As a leading AV system design platform, XTEN-AV allows integrators to build comprehensive wiring diagrams, plan device placement, and visualize control signal flow—including IR repeaters and RF extenders. By including these components in your design, you ensure reliable, clutter-free remote control for all your AV gear.

In this blog, we will explain how to modify your AV design for IR repeaters and RF extenders using best practices and how XTEN-AV makes it easy to incorporate these tools.

Step 1: Understand the Role of IR and RF Control in AV Systems

Infrared (IR) remotes use line-of-sight technology. This means the signal must directly hit the device’s IR receiver to work. If your AV equipment is inside a cabinet or in another room, the IR signal cannot reach it.

IR repeaters solve this by using a small IR sensor that picks up the signal and relays it through a wire to an IR emitter inside the cabinet.

On the other hand, RF (radio frequency) remote systems work without line-of-sight. RF extenders expand the range of these remotes, allowing users to control AV components through walls and over long distances.

Understanding how these systems work and where they should be installed is key to integrating them into your AV design.

Step 2: Determine the Type of Control Needed

Before you start modifying your wiring plan, identify which devices need remote control and what type of control signal they support.

• IR Control is common for Blu-ray players, set-top boxes, AV receivers, and TVs

• RF Control is used in systems with proprietary remotes (like Control4 or URC), lighting controllers, and multi-room audio setups

Using XTEN-AV, you can assign control types to each device in your layout. This lets you group devices by control method and plan accordingly for repeater or extender placement.

Step 3: Add IR Repeaters to the Diagram

An IR repeater system typically includes:

• An IR receiver placed where the user points the remote

• A connecting cable to carry the signal

• One or more IR emitters placed on or near the target device

• A power supply or hub unit to process signals

In XTEN-AV, you can place each of these components in your wiring diagram. Be sure to:

• Draw the path from the IR receiver to the hub and from the hub to each emitter

• Label each emitter with the device it controls

• Indicate whether the emitter is visible or hidden (like a stick-on type)

This level of detail helps installers know exactly where to run cables and how to mount each component.

Step 4: Integrate RF Extenders into Your Layout

For RF systems, you need to plan for:

• An RF base station or extender, which picks up commands from the RF remote

• Wired outputs that connect to IR ports on AV gear or control processors

• Optional antennas or repeaters to increase RF coverage range

When designing with XTEN-AV:

• Place the RF extender centrally to cover the entire control area

• Connect it to controlled devices using the appropriate wiring paths

• Tag devices controlled via RF so the technician understands signal routing

• Add notes on programming or pairing steps needed for remote setup

XTEN-AV makes it easy to manage both wired and wireless devices on the same diagram.

Step 5: Address Potential Interference and Power Concerns

IR systems can be affected by ambient light, while RF systems can face interference from other wireless devices. To ensure reliable performance:

• Keep IR receivers away from direct sunlight or fluorescent lights

• Avoid routing IR wires near high-voltage lines

• Place RF antennas away from metal objects and Wi-Fi access points

• Ensure all repeater and extender components have stable power sources

In your XTEN-AV diagram, use layers or callouts to mark environmental risks and power requirements. This ensures these issues are considered during installation.

Step 6: Update Your Signal Flow and Control Diagrams

Once you have added IR repeaters and RF extenders to your wiring plan, update your control signal diagram to reflect:

• The origin of the command (IR receiver or RF remote)

• The relay path (wired or wireless)

• The endpoint device (AV source, display, amplifier)

• Any hubs or interfaces used to distribute control signals

XTEN-AV lets you create clean, accurate control diagrams alongside your physical wiring layout. These diagrams help your team program automation scenes and ensure proper signal routing.

Step 7: Document Zones and Control Scenarios

If your AV setup includes multiple rooms or control zones, be sure to document:

• Which IR receivers or RF remotes control which zones

• How signal routing is separated or combined

• Whether repeaters are dedicated per zone or shared across zones

• How feedback is handled (if at all)

With XTEN-AV, you can assign each component to a zone, generate a control matrix, and produce zone-specific installation guides. This prevents signal confusion and ensures a smooth user experience.

Step 8: Include Control Accessories in the Bill of Materials

IR repeaters and RF extenders are easy to overlook during initial budgeting. Make sure to include:

• IR receiver and emitter kits

• RF base stations or extenders

• Cables, connectors, and power supplies

• Mounting hardware

• Optional accessories like IR distribution blocks or extra antennas

XTEN-AV automatically generates a bill of materials based on your design. This ensures all control components are ordered and nothing is missed during procurement.

Conclusion

Integrating IR repeaters and RF extenders into your AV wiring plan is a smart way to enhance system usability, especially in setups with hidden components or multi-room control needs. These tools eliminate the limitations of line-of-sight control and allow users to enjoy a seamless experience.

With XTEN-AV, designing for these technologies is simple and professional. You can visualize control paths, identify component locations, tag signal types, and document everything clearly for installers and clients.

As AV systems continue to evolve, control flexibility becomes just as important as video and audio quality. Make sure your designs account for both, and let XTEN-AV help you deliver systems that are not only powerful—but also user-friendly.
