  • Includes: (1) power adapter

 

The DA1804NT is a 1-In 4-Out distribution amplifier designed to allow the connection of a single video source to as many as four display or recording devices.

The DA1804NT can pass NTSC, PAL or SECAM-type composite video signals. It can also pass high-resolution monochrome computer video such as grayscale signals used in medical imaging. The DA1804NT can handle video signals with levels up to 1.5V p-p.

Utilizing state-of-the-art ICs, the DA1804NT offers a bandwidth of 350 MHz with very flat frequency response up to 200 MHz. It also offers a differential gain of 0.15% and a differential phase of 0.15 degrees.

The DA1804NT distribution amplifier has a pre-set gain of 1.05. Each output is completely independent and can withstand shorts to ground indefinitely. Extremely rugged and compact, the DA1804NT fits easily into tight spots. Using high quality 75 ohm coaxial cable, it can drive an NTSC signal 400 feet or more.
