2 independent channels of 3G / HD / SD SDI distribution, configurable as an 1×16 with A/B input failover protection.

The DRA-8804 is a 2 channel, 3G distribution amplifier, redesigned using the latest technology and optimized to achieve the industry’s best EQ performance offering cable lengths up to 120m at 3G. Equalization and reclocking is performed on all common serial digital signals, including 3G / HD / SD SDI. Non-inverting output drivers, using the -R2 rear module, makes this ideal for distributing DVB-ASI signals as well.

With up to 8 outputs per independent input channel, the DRA-8804 can be used in space critical environments as a dual 1×8 DA, when paired with the –R2H HD-BNC rear module. This configuration allows for up to 20 1×8 DAs in a single openGear® frame, using 10 cards. With the standard 10 BNC rear module, -R2, the DRA-8804 operates as a dual 1×4 distribution amplifier utilizing all the non-inverting outputs.

Each channel is fully independent, and can run at different data rates. LED indicators at the front of the module identify the presence of incoming video, and the data rate for each independent channel.

The DRA-8804 can be configured as a single 1×16 DA and enabled with A/B input failover protection to use a backup input source when the primary input source is lost.
