<strong>DHSE6800+</strong>, <strong>DHSD6800+</strong><br />
Dual HDTV, ASI, SDI Reclocking Distribution Amplifier<br />
The <strong>DHSE6800+</strong> and <strong>DHSD6800+</strong> dual DAs provide two channels of HD/SD-SDI video distribution with<br />
cable equalizing (and reclocking on DHSE only). The DHSD/<strong>DHSE6800+</strong> Dual DA will provide four outputs<br />
for each input (2-1x4) as well as a jumper that provides a method allowing for a single-channel DA with<br />
eight outputs(1x8). The DHSE/<strong>DHSD6800+</strong>(D) has a unique LOS (loss of signal) feature. With LOS, an<br />
automatic changeover switch can be set to switch input one to input two at loss of input one.<br />
FEATURES<br />
• UNIQUE LOS FEATURE OFFERS BACKUP AT LOSS OF SIGNAL<br />
• HD/SD-SDI, ASI COMPLIANT, AND SMPTE310 DISTRIBUTION ON ALL OUTPUTS<br />
• PERFECT FOR DUAL-LINK APPLICATIONS<br />
• TWO INPUTS, FOUR OUTPUTS PER INPUT<br />
• ONE INPUT TO EIGHT OUTPUT SELECTION CAPABILITY<br />
• AUTOMATIC CABLE EQUALIZATION<br />
• AUTO/MANUAL RECLOCK ON DHSE ONLY (143/177/270/360/540 AND 1.5 GB/S)<br />
• MANUAL (FORCE) RECLOCK BYPASS OPTION<br />
• INPUT SIGNAL PRESENCE DETECTION<br />
• ALARM OUTPUT<br />
• FOR USE IN FR6802+X(F)<br />
