Kramer 104LN overview

  • 1Description

The 104LN is a unique piece of equipment that combines the functions of a distribution amplifier and a line driver. It accepts one composite video input and distributes a signal to four buffered outputs; gain and EQ controls are used to adjust the output level and equalization. The controls are used to compensate for signal losses in such situations as long cable runs. This model offers a differential input for noise elimination.

The gain control adjusts the level of the overall signal; the EQ control boosts the upper frequencies that are inherently most susceptible to loss.
High Bandwidth
At 400 MHz the bandwidth of this unit exceeds all standards for passing a composite video signal.
Compact Size
It is able to be mounted in small areas and it is compact enough to fit into a travel bag for portable applications.
AC or DC Operation
This unit comes with an AC power supply as standard equipment but, can also be powered from 12 VDC portable supplies for applications where AC power isn't easily accessed.
Differential Input
The step up feature of this model is the "differential input" offering noise elimination features.

    Kramer 104LN reviews

    104LN 1x4 Composite Video Line Amplifier is rated 4.0 out of 5 by 5.
    Rated 5 out of 5 by from Great for 4 outputs. One remote monitor or up to 4. Compact and slim profile this design allows for shelf placement, standing or bracket mounting.

    Rated 4 out of 5 by from Works Good Not great for Broadcast Ok for basic signal spliiting. Needed some additional hum buckers and other wiring adaptations to interface to various devices including broadcast truc. Each line is not individual load balanced. So if there are disimilar runs of coax you may have issues.
    Date published: 2009-09-10
    Rated 2 out of 5 by from Only worked well for a year This worked well for a year, but after that the output was incredibly noisy, and even if using a hum eliminator, the signal would get a little better, but definitely not professional quality.
    Date published: 2014-05-18
    Rated 4 out of 5 by from Less expensive than the 123 VXL. We did not need any more than the 4 outputs. Recommended by B&H we used the 104LN. Thanks, to the technical support by Joseph.

    Rated 5 out of 5 by from Simple to use, Superior manufacturing! Plug and Play! Easy to use and far superior to the competition!
