AES3 inputs are transformer coupled and should be wired using 110 ohm shielded-pair digital audio cable, with pin 2 (+), pin 3 (-), & pin 1 (ground). Input pairs 1-2 & 3-4 may each be selected for SPDIF input, and input pairs 5-6 & 7-8 may each be selected for TOSLINK input (see Rotary Encoder above). SPDIF inputs are provided on RCA jacks and should be wired using 75 ohm coaxial cable, with Tip (+) and Sleeve (ground). TOSLINK inputs utilize optical digital audio patch cables. Word Clock Out: This BNC connector provides clock output from either CobraNet or a selected input source (see Rotary Encoder above). Logic Inputs: These eight Logic Inputs allow remote control of preset configurations. Preset configurations may be assigned to Logic Inputs 1~8 using the front panel Rotary Encoder (see above), and can then be selected via external contact-closures (wired from the corresponding logic inputs to ground). CobraNet: These two RJ45 connectors provide the CobraNet digital audio interface. CobraNet allows multiple AUDIA units to share digital audio (and DSP resources) on a system network. This also allows AUDIA units to be used with CobraNet compliant devices from other manufacturers. A 10/100Base-T Ethernet switch (not hub) is required when networking multiple units. The maximum distance between any unit and an Ethernet switch is 100 meters. Additional Ethernet switches, or even fiber-optics, can be used to further extend distances between units on a system network. The primary and secondary CobraNet ports are redundant. CobraNet supports 64 channels of digital audio (32-in & 32-out) over Fast Ethernet, using CAT-5 cable. CobraNet transmits (32) channels of digital audio on (4) 'bundles' of (8) channels each. The same is true for receiving digital audio over CobraNet. Bundle numbers are used to determine where digital audio is transmitted and received. Typically, 'unicast' bundle numbers (256~61,439) are used to exchange digital audio between two specific devices. With 'unicast' bundles, each CobraNet device can transmit to no more than (4) other devices within a network. With 'multicast' bundle numbers (1~255), digital audio can be exchanged with multiple devices. Due to network delay, CobraNet has a limitation of seven (7) 'hops' (one-way transmissions) within a network. In order to integrate AudiaEXPI-D into a AUDIA system, an EXPI-D (or CobraNet) input block must first be placed into the design layout. AUDIA units intended to receive digital audio from the AudiaEXPI-D must have their CobraNet jacks connected to the same network. Both the AudiaEXPI-D unit (hardware) and the EXPI-D input block (software) must be assigned matching bundle numbers, before digital audio can be successfully exchanged. AudiaEXPI-D bundle number assignment can be changed in real-time to allow routing of digital audio to different EXPI-D input blocks within the system. CobraNet Latency settings must be identical in all devices, system-wide. Also, unicast and multicast bundle numbers can be used to route digital audio to individual or multiple EXPI-D input blocks. Similar considerations may also apply when using AudiaEXPI-D with other CobraNet compliant systems or devices. AudiaEXPI-D and AudiaEXPO-D can exchange digital audio directly (outside of a system network) using either a simple 'cross-over' CAT5 cable or an Ethernet switch. 2 AudiaEXPO-D - Front & Rear Panels BIAMP SYSTEMS -D Rotary Encoder & LCD Display: This control and display are used for initial setup of the AudiaEXPI unit.

To promote the adoption of AES67, The Media Networking Alliance (MNA) was formed in October 2014.

  • EDUCATION Connected Lecture Hall with a Hybrid Solution of Networked
    APPLICATION BRIEF EDUCATION Connected Lecture Hall with a Hybrid Solution of Networked and Centralized AV, Audio Reinforcement and Intuitive Control OPPORTUNITY Large learning spaces like Lecture Halls go beyond the audiovisual content sharing needs of smaller spaces. While technology that supports intuitive content sharing is still critical, so is added audio reinforcement for voice and content. It may also be important to capture and stream content to overflow spaces. SOLUTION HARMAN Professional solutions offers a wide range of choices for any audiovisual requirement. The solution example in this application brief includes podium-friendly technology solutions for the instructor offering system control and access to a variety of content options. It also includes wallplate connections for additional visiting devices to share content. The core video distribution system distributes high-resolution video to large screens and displays for clear audience view; while the audio system provides reinforcement for both content and voice. Finally, networked AV connections enable content captured in the lecture hall to be shared to overflow spaces, throughout the campus, and even over the internet to other sites. The system can support virtually any source. Here, a Blu-ray player, document camera, and accessible connections for BYOD devices like laptops are included in the podium. An AMX HyrdraPort connectivity solution provides access to connections at the podium, while a Modero G5 7" wall mount control panel installed in the podium allows instructors to control both content and equipment. The system also has access to a room-PC and/or additional sources in the AV closet, and can stream content to and from the campus LAN.

  • Public Address System Network Design Considerations
    AtlasIED APPLICATION NOTE Public Address System Network Design Considerations Background AtlasIED provides network based Public Address Systems (PAS) that are deployed on a wide variety of networks at end user facilities worldwide. As such, a primary factor, directly impacting the reliability of the PAS, is a properly configured, reliable, well-performing network on which the PAS resides/functions. AtlasIED relies solely upon the end user’s network owner/manager for the design, provision, configuration and maintenance of the network, in a manner that enables proper PAS functionability/functionality. Should the network on which the PAS resides be improperly designed, configured, maintained, malfunctions or undergoes changes or modifications, impacts to the reliability, functionality or stability of the PAS can be expected, resulting in system anomalies that are outside the control of AtlasIED. In such instances, AtlasIED can be a resource to, and support the end user’s network owner/manager in diagnosing the problems and restoring the PAS to a fully functioning and reliable state. However, for network related issues, AtlasIED would look to the end user to recover the costs associated with such activities. While AtlasIED should not be expected to actually design a facility’s network, nor make formal recommendations on specific network equipment to use, this application note provides factors to consider – best practices – when designing a network for public address equipment, along with some wisdom and possible pitfalls that have been gleaned from past experiences in deploying large scale systems. This application note is divided into the following sections: n Local Network – The network that typically hosts one announcement controller and its peripherals.
