FiberPlex Expands LightViper Line

32 Input AES3 fiber optic ?digital audio snake? offers advanced technology solution (March 11, 2005)

FiberPlex, Inc., the leading fiber optic supplier to the professional audio industry, adds the VIS-4832 bi-directional digital snake system to its LightViper range of military-grade fiber optic products for the professional audio market.

The new LightViper VIS-4832 digital snake system is an AES3 digital audio alternative for the companys highly-acclaimed VIS-1832 Fiber Optic 32 x 8 Analog Snake Head and consists of two (2) 1U electronic rack mount units and the requisite fiber optic cable. The VIS-4832 stage ?head will accept sixteen (16) AES3 digital inputs (32 audio channels). The systems outputs consist of four (4) AES3 digital outputs and eight (8) analog line level outputs. Two (2) additional Fiber Split outputs are available for monitoring. A dual fiber optic ?tactical grade cable connects the systems two components to provide a ?pure digital signal transmission path of up to thirty-two (32) channels of remote microphone preamplifiers. By simultaneous use of the systems digital and analog outputs, it can transport digital mix busses to a digital, analog, or a mixed drive rack.

The VIS-4832 will also handle an optional 10/100 Ethernet portal over fiber and it features both 48 and 96 kHz Word and Super Clock outputs.

In a related announcement from the company, starting in April 2005, all LightViper 1832 systems will support 48 kHz sampling rates (VIS-1832, VIM-1832, VIM-1032, VIS-4832, VIM-1808/0808). The 48 kHz mode is selected by feeding 48K word clock into the clock input. This new feature allows for greater channel density when interfacing with digital consoles (e.g. Yamaha PM5D, DM2000 digital consoles with ?Y cards) and is also useful for direct digital feeds to computer-based recording systems. Additionally, all 1832 Systems will support an optional 10/100 Ethernet portal over fiber (VIS-1832, VIM-1832, VIS-4832, VIM-1808/0808) with the use of a four (4) fiber connectors and a 4-core fiber optic cable.

A primary application for the VIS-4832 digital snake is the transmission of signals from the output of existing high-quality microphone preamps directly to the inputs of a digital console. This eliminates the need to convert signals from the digital domain into an analog signal, send these converted signals through a conventional copper snake, and then, subsequently reconvert them from the analog domain back into a digital one at the mixing console.

The digital snake system may also be deployed as a ?drive rack snake. Digital outputs of a mixing console may be sent directly through a LightViper fiber optic cable to the digital inputs of power amplifiers; this topology maintains an all-digital signal path throughout the entire audio signal chain. In addition, the digital snake system will simultaneously route the consoles digital output to both high-end power amps with digital inputs and to conventional monitor amps with analog inputs.

LightVipers fiber optic cable offers total signal path isolation between both stage and mixer as well as between the mixer and power amplification; the cable is totally immune to ground loops, RFI, EMI and electromechanical noise, and runs of up to 1 1/4 miles (6,600 feet) can be easily accomplished without signal loss or degradation.

FiberPlex includes a limited lifetime warranty with all of its LightViper system components.

The suggested Professional Audio user price for a typical VIS-4832 LightViper digital snake system configuration is $6,446.00; this includes all components [(2) VCB-DDXM-10, (2) VCB-DDXF-10, VCB-DDXM4-10, VCB-DDXF4-10, VFC-0100] and all cable terminations with 100 feet of fiber optic cable for a pure digital solution.

About FiberPlex
FiberPlex designs and manufacturers an extensive line of proprietary communications products that address the most challenging applications. They use fiber-optic technology to solve security, noise and distance problems. FiberPlex products allow the system integrator to bridge between the several interface standards that may be present in a communications network. Proprietary timing and buffering products help keep networks in synchronization even though they have separate clock sources.
