Gefen's AV over IP solutions continue their tradition of providing high performance, scalable, expandable, and secure AV routing and distribution over a standard Gigabit Local Area Network. The Digital and Analog Audio over IP Sender (EXT-ADA-LAN-TX) and Receiver (EXT-ADA-LAN-RX) are a much-needed audio-only option for background music, public announcements, and other applications where stand-alone audio needs to be distributed through the AV system. Audio input and output options include L/R Analog, Coaxial Digital, and Optical Digital. When using the digital inputs and outputs, 2-channel PCM and up to 5.1 channels of Bitstream can be distributed through the system. In addition to audio, RS-232 and 2-way IR can also be independently routed and distributed for source and amplifier control. The entire Gen 2.0 product line, including the audio models, feature backward-compatibility with our first-generation products.
