TheVIM‐1808/0808
YouhavepurchasedtheLightViper1808/0808system,an8x8linelevelanalog/AESdigitalinputfiber‐optictransportsystem(snake).
Insteadoftraditionalheavymulti‐conductorcoppercable,LightViperfiberopticsystemsutilizelightweight,flexible,militarytacticalgrade
fiber‐opticcableorduplexPVCandplenumratedfiberforinstallationuse.
TheFiberAdvantage
Fiberopticsoffermanyadvantagesovercopper:
Transmitslightratherthanelectrons
Transmissionovergreaterdistances(morethan2Km[1.25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
TheLightViper1808/0808isanactivedevice.Becauseofthis,therearesomeaspectsofthisnewtechnologythatrequiresomeslightly
differentthinking:
TheLightViper1808/0808systemrequiresACPoweratboththeStage(VIM‐0808)andtheconsole(VIM‐1808)
The1808/0808systemcontains(8)LineLevelAnaloginputsOR(8)AESdigitalinputs,and(8)analogAND(8)AES
digitaloutputs.Therearenomicrophonepreamplifiersaswiththe1832system
AllinputsexitthesnakeatLineLevel
InputandOutputflexibilitymayeliminatetheneedforsomeofyouroutboardgear
TheLightViperVIM‐1808/0808isanactivedevice,thereforedonotattempttoconnectintercomintothereturns
ThereturnsintheVIM‐1808/0808cannotbe“turnedaround”toprovide(8)sendsonewayaswithatraditional
coppersnake,astheelectronicsforthereturnsarecontainedintheVIM‐1808.
