IR Extender Spacetronik SP-IR04 — cabinet IR repeater for remote control signal extension

Spacetronik SP-IR04 is an IR extender and repeater designed to receive infrared remote control commands and retransmit them to audio‑visual equipment placed inside cabinets, behind furniture, or otherwise out of direct line of sight. The unit enables remote operation of set‑top boxes, DVD/Blu‑ray players, AV receivers and other IR‑controlled devices by capturing signals from a handheld remote and delivering them to the hidden equipment.

Advantages

The device provides reliable IR signal reception and retransmission to allow normal remote control operation when devices are not visible. It supports straightforward installation in media cabinets and home entertainment setups and eliminates the need to open doors or reposition equipment to control devices. The compact design makes it easy to integrate into existing AV furniture without taking up significant space.

Suitable for

• Home entertainment systems with equipment stored in cabinets or closets
• Professional AV installations where components are rack‑mounted or concealed
• Rooms with limited line of sight between remote control and devices
• Situations requiring centralized control of multiple IR devices from a single remote

Key specifications

• Function: infrared signal reception and retransmission (IR extender / repeater)
• Compatibility: standard consumer IR remote control protocols for AV equipment
• Form factor: compact module suitable for placement inside cabinets or near equipment
• Connection: IR receiver and IR emitter interface for signal capture and output
• Power supply: designed for low power consumption (use specified adapter or power source)

How to use

Position the IR receiver where it can reliably pick up signals from the remote control and place the IR emitter(s) near the front panels or IR windows of the target devices. Connect power according to the supplied instructions and verify that the extender is active by sending commands from the remote; the connected devices should respond as if they were in direct line of sight. Adjust placement of the receiver and emitter for optimal signal strength if necessary.

Usage recommendations

For best performance, avoid placing the IR receiver and emitters behind thick metal surfaces or materials that strongly block infrared light. Keep the emitter LED aligned with the device IR sensor and ensure the receiver faces the typical remote control position in the room. When controlling multiple devices, place emitters close to each device’s IR window to prevent cross‑interference.
