DA-DH/DHR6802+D

Dual 1x4 or Single 1x8 with Built-in ACO, 3G/HD/SD/ASI

The DA-DH/DHR6802+D has been superseded by the DA-DH/DHR6804+D.

The DA-DHR6802+D dual distribution amplifier (DA) provides two channels of 3G/HD/SDI/ASI/SMTPE310 video distribution with cable equalizing and reclocking. Built for use with the 6800+™ modular core processing platform, the DA-DH6802+D dual DA provides two channels of 3G/HD/SDI/ASI/SMTPE310 video distribution with cable equalizing and is non-reclocking.

The DA-DH6802+D and DA-DHR6802+D dual DAs have four outputs for each input (two 1x4) and are user configurable to function as single-channel DAs with eight outputs (1x8).

The DA-DH6802+D and DA-DHR6802+D dual DAs feature broadcast-quality performance that exceeds SMPTE specifications. Software configuration of all parameters and remote indication of signal presence and alarms are standard.

Features

  • Cost-effective DA with equalizing and reclocking (DA-DHR6802+D only)
  • Dual 1x4 configurable as 1x8
  • Automatic cable equalization on inputs
  • Automatic or forced rate detection
  • Reclocking with automatic or forced bypass (DA-DHR6802+D only)
  • Identical polarity for ASI compatibility on all outputs
  • Built-in automatic changeover (ACO) protection between inputs
  • Feedback status reports input signals present and locked
  • Card-edge control with LED feedback
  • Remote control with status and alarm
  • 20 channels of 1x4 or 10 channels of 1x8 distribution in a 2RU 6800+ frame

Product Details

The DA-DH6802+D and DA-DHR6802+D DAs provide 20 channels of 1x4 or 10 channels of 1x8 3G/HD/SDI/ASI/SMTPE310 distribution in a 2RU 6800+ frame with low power consumption and non-inverting ASI compatibility on all outputs.

The DA-DH6802+D and DA-DHR6802+D protect your signal path with a unique automatic changeover (ACO) feature. With the built-in ACO, an automatic failover can be set to switch the primary input to the secondary with the loss of signal on the primary input. The user can select which input is designated as primary and which is designated as secondary. This further leverages your investment and allows a backup to live or sync feeds directly on this DA.
