DGlink digital audio distribution system leverages a long lineage of analog/digital cables, connectors, and circuitry (all manufactured by Link) to produce a truly modular touring grade digital distribution system. DGlink is a digital snake designed for live events leveraging the architecture of traditional Stage Boxes. The primary objective is to offer a solution that will replace, or integrate with, traditional audio distribution systems (analog and digital) during live applications, utilizing one, or multiple, digital standards over CAT 5 or 6 cables. The Digital Protocol Modules support use of different digital audio standards(Dante, Ethersound, MADI) in a single system.
Digital Stage Box
Our company’s mission has always been to solve any problem concerning connection, transport and massive distribution of audio signals, therefore we thought we should contribute by providing a solution that minimizes the problems encountered by audio professionals.
The very first item designed and produced in line with this philosophy is a digital stage box that can be used with different audio protocols – up to two simultaneously – so as to also work as a format converter making it possible to use mixers or other equipment supporting different audio formats together.
One of our primary goals is to give a new life to equipment that may otherwise remain unused because it is incompatible with more recent or better performing standards or formats.
For this reason, in addition to hybrid digital/analog systems, it is possible to use different digital mixers – one for the stage and one for the house – by managing two different audio formats at the same time, or to convert audio signals for an HD or DAW recording system in one of the EtherSound, Dante or MADI formats.
Redundant Rugged Switches
Due to the needed high quality of audio, video, data and control signals, number of channels and low latency needs, Audio over Ethernet is a critical topic for most of the network switchers. In fact, Audio over Ethernet systems require a high bit rate and minimum latency (less than 10 milliseconds), so it’s necessary to use a dedicated LAN (Local Area Network) or VLAN (Virtual LAN), overprovisioning and/or QoS (Quality of Service) features. Being aware that to be reliable the switch must perfectly suit Layer 3 protocols, our Redundant Rugged Switch line was created with the highest performance requirements, in which we choose the third party switches chosen after tough and prolonged tour grade tests. So we’re proud to supply to audio industry and professionals switches nearly free from problems like low throughput, dropped packets, bit errors, jitter, out-of-order delivery and with very low latency.
Our Switches are housed in sturdy 19” cases, with redundant power supplies and include LEDs indicating the activity. These solutions can manage primary and secondary ports and are totally compatible with the stringent Dante and AVB standards.
Multinetwork Optical Backbone
Being aware that today’s entertainment industry uses many different protocols and technologies, like audio, video, and lighting, we integrated our DGLink range of products with MultiNetwork Optical Backbone, a discrete modular based solution providing a discrete channels for the various protocols, and able to cover distances up to 120 km!
Our modules comply to ITU G.695 and G.696 ITU o T G.652 (11/2009) standards and provide up to 18 channels that can be used for the connection of different signals such as 3G HD-SDI, MADI, AES, Dante, Ethernet, and storage data (8G/4G/2GI 1GFibre Channel), and any convertible data, like DMX and RS232, without complex protocol conversion technologies. The 4, 8, 16 or 18 channel modules, combine and split optical signals coming from and heading to our units; furthermore, DGLink MultiNetwork Optical Backbone modules perfectly combine with all major broadcast products and with different Fiber Optic connectors: LC or SC for local wavelength channels, and Lemo, OpticalConn or Expanded Beam connectors for the long distance unit-to-unit mobile connections.
