The OutBox R8 CobraNet® Audio Output Interface from Attero Tech is a cost-effective, line-level wall box that features 8 unbalanced RCA outputs, that can be used either with 8 mono outputs or 4 stereo outputs. It's designed to fit into most dual gang junction boxes, and is PoE enabled, so all connectivity (both power and audio data) to the R8 is provided via a single CAT-5 cable. It's a terrific cost-effective solution for getting great sounding unbalanced audio out of the CobraNet without the degradation of signal, cable costs, and troubleshooting of working with analog. Available in Black or White.

  • Works with Consumer Electronics
    Eight RCA channels consumer devices including TVs, radios, CD players, iPods, etc.
  • Includes Advanced DSP
    As CobraNet bundles have usually already run through a DSP by the time they reach an OutBox, all you need are the basics – limiter, gain, and delay – just in case you may still need to tweak the signal for your receiving device.
  • Uses PoE Power - A single CAT-5, and now you're live
    Ethernet provides power, 8 audio channels, control signals, and CobraNet protocol from DSP, or right from some other Out-of-the-Box product.
  • CobraNet Audio Output - Durable and user-proofed
    There's just no easier, more cost-effective way to provide an analog signal from your CobraNet network, and deliver its output it to the world.
