Understanding repeater IR systems
What is an IR Repeater System?
In a home theater projector setup, controlling devices like your cable box, Blu-ray player, or streaming product can be tricky, especially when these components are hidden away in cabinets or mounted behind walls. An IR (infrared) repeater system, sometimes called a control extender or repeater kit, is designed to solve this problem. It lets you use your original remote control to operate devices that are out of direct line of sight.
Key Components and How They Work Together
Most IR repeater systems include a few essential parts:
- IR Receiver: This small sensor picks up signals from your remote control. It can be wall mounted or placed near your projector screen for easy access.
- Emitter: The emitter sends the remote's signal to your hidden devices. Some kits include multiple emitters for controlling several products at once, like a Blu-ray player and a cable box.
- Repeater or Extender Module: This unit processes the signal from the receiver and relays it to the emitters. Some systems are USB powered, while others use a vdc adapter.
- Extension Cable: Useful for reaching devices that are far from the receiver, especially in larger home theater rooms.
Why Consider a Repeater System?
Many modern home theater setups use projectors, HDMI switchers, and other components that are often hidden for a clean look. This can make it difficult for your remote control to communicate with these devices. An IR repeater kit or wireless pro repeater system can save you the hassle of opening cabinets or pointing your remote in awkward directions. Some advanced products, like the BlastIR or Sewell BlastIR Wireless, offer extended range khz and wireless pro features for even more flexibility.
What to Look For in a Repeater Kit
When shopping for an IR repeater system, consider:
- Price and Package Quantity: Kits vary in price depending on the number of emitters, receivers, and extension cables included.
- Compatibility: Make sure the system supports the range khz of your remote controls and devices.
- Power Options: Some kits are USB powered, while others require a separate power supply.
- Installation Flexibility: Look for wall mounted options or kits with long extension cables for custom setups.

Common remote control challenges in home theater projector setups
Why Remote Controls Struggle in Home Theater Setups
Setting up a home theater projector often means hiding devices like your cable box, Blu ray player, or streaming products out of sight. While this creates a clean look, it introduces a common problem: your original remote control may not work as expected. Infrared (IR) signals need a clear line of sight. When equipment is tucked away in cabinets, wall mounted, or placed behind the projector screen, the IR signals can’t reach the devices. This is where a repeater or control extender becomes essential.
Typical Scenarios Where IR Control Fails
- Hidden Components: Devices placed in closed cabinets or behind walls block the IR signal, making it impossible for the remote to communicate.
- Long Distances: Large rooms or projector setups with equipment far from the seating area can exceed the remote’s range khz, causing unreliable control.
- Multiple Devices: Managing several products, such as a Blu ray player, cable box, and AV receiver, increases the challenge of controlling everything from one spot.
- Wall Mounted Projectors: Projectors or other components mounted high up or behind the viewer may not receive direct IR signals.
Why a Repeater Kit or Control Extender Makes Sense
To solve these challenges, a repeater kit or IR extender kit can relay the remote’s signal to your hidden devices. These systems use an emitter and receiver setup, sometimes with a usb powered option for convenience. For example, a product like the Sewell BlastIR Pro repeater kit or BlastIR wireless pro can help you control hidden devices without moving from your seat. Some kits include an extension cable for flexible placement, and certain packages offer different package quantity options to match your needs.
When comparing products, consider the price, range khz, and whether you need a usb repeater or a wireless pro system. Some kits are designed specifically for HDMI setups, while others work with a wider range of devices. Look for features like vdc compatibility, emitter receiver pairs, and the ability to control multiple devices from a single remote.

How a repeater IR system works with projectors
How IR signals travel from your remote to the projector
In many home theater setups, the projector and other devices like a cable box or Blu-ray player are hidden away in cabinets or mounted on the wall. This can make it tough for the original remote control to reach the projector’s IR sensor. That’s where a repeater IR system comes in. It acts as a bridge, capturing the remote’s signal and sending it to your projector and other hidden devices.
Key components of a repeater IR system
- IR Receiver: Placed in view of your remote, often near your screen or on a wall. It picks up the signal from your remote control.
- IR Emitter: Small devices that stick onto or near the IR sensor of your projector, cable box, or Blu-ray player. They "blast" the signal received from the remote.
- Repeater Hub or Extender Kit: This is the central unit that connects the receiver and emitters, sometimes powered by USB or a vdc adapter. Some kits, like the BlastIR Wireless Pro, offer wireless options for more flexibility.
How the system operates in real-world setups
When you press a button on your remote, the IR receiver picks up the signal. The repeater kit then transmits this signal through extension cables or wirelessly to the emitters. The emitters send the signal directly to your projector and other devices, allowing you to control hidden equipment without line-of-sight. This is especially useful for wall mounted projectors or when using a control extender for devices tucked away in cabinets.
Some products, like the Sewell BlastIR Link, offer USB powered options and support a wide range khz for compatibility with most remotes. The package quantity and price can vary depending on the number of emitters and receivers included. For larger setups, a pro repeater or extender kit may be needed to cover more devices or longer distances.
Compatibility and integration tips
- Check if your repeater system supports your projector’s IR frequency (range khz).
- Consider if you need a wireless pro model for more flexibility or a standard kit with extension cable for a wired connection.
- Some kits are designed for easy integration with HDMI setups or can be powered via USB for convenience.
