Composite & Component

The LINK LEI-555 serial distribution amplifier

restores the incoming signal to its proper

amplitude. The signal is reshaped with automatic

equalization, re-slicing and DC restoration. The

LEI-555 re-clocks the input signal for distribution

over longer distance cables, up to 500 feet. Six

outputs are provided on the rear panel.

A module fault LED on the front panel indicates a

weak signal or no input signal present. The

sensitivity of the LED indicator may be adjusted to

suit the users needs.

The LEI-555 input signal is may be composite

143Mb/s or component 270Mb/s. An internal

jumper selects the desired standard. The unit has

two LED's that show power supply status and

signal present.

TheLEIseriesdigitalproductsarecompactdesign

that allow three modules to mount in the PRT-700

mounting tray.

Backed by Link's 10-year warranty, the LEI-555

will provide years of outstanding performance.
