Datasheet (1.69Mb) | Feature Highlights (1.42Mb)

12G / 6G / 3G / HD / SD-SDI Re-Clocking Distribution Amplifier.


Key Features

Multi-Rate: Auto-sensing and distributing 12G / 6G / 3G / HD / SD-SDI inputs.
Adaptable Cable Equalization: Compensates for signal losses and improves signal transmission distances beyond 500m (SD-SDI via 1694a coax cable).
Automatic Output Re-Clocking: Restores signal integrity and reduces jitters over long cable runs.
Flexible Signal Routing: Easily configured through DIP switch settings.



The Pacific DA-204 is a modular card-based, high performance reclocking distribution amplifier.
Featuring automatic input data rate detection, the Pacific DA-204 is capable of distributing multi-rate SDI signals over long distance without signal degradation. All active components, including two types of cards supporting up to 12G and 3G-SDI respectively, are hot-swappable and field-serviceable that aim to facilitate maximum flexibility and minimize unnecessary downtime. Each card features 2 inputs and 4 outputs; up to 8 independent cards can be installed in an 1RU rackmount chassis. The Pacific DA-204 incorporates adaptive cable equalizer, reclocker, and low-jitter cable driver, ensuring long cable runs while maintaining optimal signal integrity for high resolution videos. Automatic signal presence detection and easily configurable DIP switch settings allow flexible signal distribution. The Pacific DA-204 supports easy integration into both new and existing AV systems. It is also a powerful complement product to Avitech multiviewers and wall processors.

Manual Routing Configuration

By configuring the DIP switch setting corresponding to each modular card, the Pacific DA-204 can be set to perform signal distribution in one of the 3 manual routings as follows:

Automatic Routing Configuration

By configuring the DIP switch setting to automatic routing, the Pacific DA-204 will intelligently perform signal distribution based on the presence of valid inputs. It requires less than 60 milliseconds response time to detect signal presence and finish altering signal routings.

Reliable Backup Solution

Featuring automatic signal presence detection, the Pacific DA-204 automatically switches to the valid input in case signal loss of either input, forming a low-cost backup solution in signal distribution.

Compact SDI Distribution Amplifier

The Pacific DA-204 12Gs and 3Gs are standalone, multi-rate SDI reclocking distribution amplifiers designed for small-scale signal distribution. Each accommodating 2 SDI inputs and 4 SDI outputs, as well as routing flexibility and adaptive equalizer as the modular model, these compact distribution amplifiers ensure unmatched quality and reliability with the simplest installation.
