Introduction
Congratulations on your purchase of a Light Viper 1832 fiber optic audio snake—a lightweight,
flexible breakthrough for professional sound production.
Light Viper products are designed, engineered and manufactured by FiberPlex, experts in fiber
optics with decades of experience. Our work in audio and data communications products is
known in US government applications worldwide. Light Viper products,
combine our pioneering technology with the highest standards in audio engineering.
The Light Viper
You have purchased the LightViper 1832 system, a 32 x 8 Fiber Optic Transport System (FTS)
that has the function, look and feel of a traditional copper snake; however instead of a heavy
multi-conductor cable the Light Viper snake features a lightweight, flexible fiber built to
"ruggedized" military standards.
The Fiber Advantage
Fiber optics offer many advantages over copper:
• Transmits light rather than electrons
• Transmission over greater distances (more than 11⁄4 mile)
• Complete electrical isolation
• Immunity to RFI and EMI
• Eliminates ground loop problems
• Can be routed overhead, through walls, or underground
• Avoids foot traffic while maintaining aesthetics
Functional Considerations
Although the Light Viper 1832 looks essentially the same as a traditional, passive snake, it is an
active device. Because of this, there are some aspects of this new technology that require
some slightly different thinking:
• The Light Viper 1832 requires AC Power at both the Stage Box and the Mixer
Unit(s)
• Phantom Power is delivered from the Stage Box, NOT the console
• The snake has three selectable gain settings and a clip indicator at each input on
the Stage Box
• All inputs exit the snake (at the Mixer Box) at Line Level
• DI boxes are not necessary in most cases
• Input and Output flexibility may eliminate the need for some of your outboard
gear
• The LightViper VIM-1832 is an active device, therefore do not attempt to connect
intercom into the returns
• The returns in the VIS-1832 cannot be "turned around" to provide 40 sends one
way as with a traditional copper snake, as the electronics for the returns are
contained in the VIM-1832.
