ABOUT YOUR DISTRIBUTION AMPLIFIER 2

The DA1203RM Distribution Amplifier is designed to allow the connection of a single computer or other video source to as many as three scan-rate compatible display devices.

Though primarily designed to pass RGBS format signals, the DA1203RM can also pass RGsB, Component Video (Y, R-Y, B-Y), S-Video (Y/C), and Composite Video by using the appropriate analog channels (Red, Green, Blue).

The analog channels (Red, Green, Blue) are designed to pass video levels up to 1.5V p-p offering a 0.15% differential gain and 0.16 degree differential phase to assure the highest quality video signal.

The DA1203RM offers switches for Gain, Sync Level, and Sync Polarity. The Gain Switch boosts the output of the amplifier by 35% for use, with long cable runs. The DA1203RM uses AGC (automatic gain control) circuitry, which converts all incoming sync levels to either 4V p-p or 2V p-p. This AGC circuitry is selectable with the Sync Level switch. This enables it to be compatible, with current and older display equipment. The Sync Polarity switch reverses the polarity of the incoming sync for compatibility with various displays.

The DA1203RM Distribution Amplifier is a state-of- the-art product with a video bandwidth of 350 MHz, enabling it to remain transparent to the video signal passing through it. Each output is individually buffered and is not affected by other output loading.

The DA1203RM offers an internal 90-140/200- 240V power supply and can be rack mounted using optional accessories hardware ( DA1299RM – rack ears for single unit and DA1298RM – rack shelf for two units side-by-side).
