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.
