Gold Series A/V System

SL-1977-x

4x6 Video Buffer Isolator Module

SpecificationPinoutsInstallation Note

Features and Functions
  • Lightweight, modular design
  • Use to eliminate Ground Loops interference on Video Distribution networks.
  • Ultra high graded audio isolation transformer provided superb transfer characteristic.
  • 4 Isolated, Identical, 1 to 6 buffered Segments layout for easy diagnostic and installations.

Description

The SL-1977 module splits 4 Video inputs into 6 outputs per channel, bringing the total output channels to 24.  The module provides ground isolation to minimize the ground loop effect, resulting in improved video quality.  The flexibility provided by this design will allow for multiple A/V rack setups, while retaining high quality audio output.

 

Application
  • Buffer and distribute the video sources from the main source rack to six A/V distribution racks.
  • Provide ground isolation to minimize the ground loop effect
