Marshall VDA-104-3GS-2 1×4 3G-HD-SD-SDI Re-Clocking Distribution Amplifier

Safety Instructions

The VDA-104-3GS-2 1×4 3G/HD/SD-SDI Re-clocking Distribution Amplifier has been tested for conformance to safety regulations and requirements and has been certified for international use. However, like all electronic equipment, the VDA-104-3GS-2 should be used with care. Please read and follow the safety instructions to protect yourself from possible injury and to minimize the risk of damage to the unit.

Follow all instructions and warnings marked on this unit.
Do not attempt to service this unit, except where explained in this manual.
Provide proper ventilation and air circulation and do not use near water.
Keep objects that might damage the device and assure that the placement of this unit is on a stable surface.
Use only the power adapter and power cords and connection cables designed for this unit.
Do not use liquid or aerosol cleaners to clean this unit. Always unplug the power to the device before cleaning.

Introduction

The VDA-104-3GS-2 receives one SDI input, perfectly duplicates it, and re- transmits four SDI outputs for real time multi-viewing. It is a reliable video device splitting a SDI, HD-SDI, or 3G-SDI video source to four SDI compliant displays at the same time. Besides, built-in re-clocking & equalization features provide the best performance for SDI distribution amplifier.

Features

3G/HD/SD triple-rate distribution
Four separately buffered and re-clocked outputs
Supported SDI format
» 3G-SDI (SMPTE 424M, 425M level A,B up to 2.97 Gbps)
» HD-SDI (SMPTE 292M, 296M up to 1.485 Gbps)
» SD-SDI (SMPTE 259M, up to 270 Mbps)
Cable equalization (Belden 1694A) and signal retiming
Video bandwidth: 2.97Gbps, 2.97/1.001Gbps
Automatic detection of 3G/HD/SD-SDI signals
Dual color LED indication of input lock and rate
Passes all ancillary data
Provides automatic cable equalization
» [3G-SDI]* >120m (394ft)
» [HD-SDI] >200m (656ft)
» [SD-SDI] >300m (984ft)
Re-clocks SDI signals for cascading and thus longer transmission
Inter-locked power supply for better fixedness

Note: The cable length depends on the characteristics and quality of the cables.
