  • Video Gain Switch (0.7V/1.0V)

  • Sync Level Switch (2V/4V)

  • Sync Polarity Switch

  • 2-U High, 1/2 Rack Wide

  • Rack-mountable with optional hardware

  • Internal Power Supply (90-140V/200-240V)

The DA1203RM is a 1-In 3-Out RGBS high-resolution video distribution amplifier designed to allow the connection of a single computer 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 utilizing the appropriate analog channels (Red, Green, and 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 a 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 cables. The DA1203RM utilizes AGC (automatic gain control) circuitry, which converts all incoming sync levels to either 4Vp-p or 2Vp-p, selectable with the Sync Level switch. This enables it to be compatible with older display equipment. The Sync Polarity switch reverses the polarity of the incoming sync for compatibility with various displays.

The DA1203RM offers an internal power supply and can be rack-mounted using optional accessory hardware.
