Essential Info

Enhance the flexibility of your audio/video system with the Buffalo Electronics 4 Emitter Infrared Connecting Block. This device collects signals from room IR sensors, processes them and sends the signals to your audio/video equipment via an infrared emitter. With its robust construction and comprehensive noise shielding, the Infrared Connecting Block is designed to provide you with a highly-reliable and accurate audio/video control system.

IR sensor, IR emitters and 9-12VDC power supply are required (sold seperately).


What's Included

  • 1x - Four Emitter Infrared Connecting Block
  • More Info

    You can configure the Infrared Connecting Block using multiple options, depending on the size and scope of your audio/video system. If multiple connecting blocks will be used, the system allows for 2 different expansion options: one for situations where only additional flashers are required, and another for scenarios where you might need additional flashers and repeaters. You can link up to 15 infrared repeaters to the Connecting Block.

    The Infrared Connecting Block also features LED flashers, making installation a snap. If the system is installed correctly, the LED flashers will light up when IR signals are sensed. The Infrared Connecting Block features 4 voltage-regulated flasher output jacks, allowing each Connecting Block to control up to four audio/video devices. To ensure proper installation, the unit must be installed near the audio/video equipment and near a 115-VAC outlet.

    Cat. 5 cable is recommended for connections.

    This connecting block was easy to setup and use. I just powered it up and connected everything and it just works.
    GARY -- st. charles, MO   5/15/2009
    Very easy to install, just be aware that the connection order of the input wires from IR Sensors can be a different configuration than the sensor -- confused me for a while.

    Works as expected. Good value.
    FRANK -- charlotte, NC   5/4/2009
