It can be used for simple point-topoint connections or can form a distribution backbone for sending up to 16 audio channels to multiple remote locations. [. . . ] All locations have access to 16 channels of digital audio without concern over ground loops or induced noise. se K8 as a mini snake for sending audio feeds from an auditorium out a remote broadcast truck. U ount a K8 device in a cluster of powered speakers and drive the entire cluster with a single category 5 cable. M se K8 as a digital snake between the mixing console and the amplifier racks. Put another K8 branch and output U device on stage to drive the stage monitors. Distribute central background music and paging out to individual venue systems in cruise ships, entertainment facilities, convention centers, schools and conference facilities. K8-AI8 ARCHITECT & ENGINEERING SPECS The audio transport system shall carry 16 channels of digital audio integrated with bi-directional remote control and monitoring data over a single category 5 cable up to 200 meters in length without being actively refreshed. The digital audio format shall be uncompressed, 48kHz sampling rate, 24 bit quantization depth and shall have a total latency from analog to analog through the transport system of less than 0. 5 milliseconds. The system shall pass audio when powered up with no software configuration required. The input to the digital audio system shall be via an 8 channel analog encoder with XLR/1/4" female combination connectors mounted in an EIA standard 1 unit rackmount case with universal voltage power supply. The signal to noise ratio of the system shall be greater than 100 dB and the audio input device shall drive 2 individual category 5 cables to a length of 200 meters. [. . . ] Termination of the digital audio and control lines shall be made with DIP switches on the rear panel. The analog audio input to the digital audio system shall be K+H K8-AI8.
