Extron P/2 DA2 Plus 分配放大器可使计算机的输出信号传送至两台显示器。 P/2 DA2 PLUS 是一款1 路输入2 路输出VGA 分配放大器，具有300 MHz （-3dB）的RGB 视频带宽；能用Extron VGA 微型高分辨(Mini HR) 电缆，将VGA-UXGA 计算机信号驱动远至80 米。P/2 DA2 P 能将一路高清晰度 VGA-UXGA 输入信号拆分成2 路输出，带有一根标准VGA 输入电缆。
特性
·1 路输入、2 路输出、VGA-QXGA 信号分配
·2 路输出均单独缓冲
·兼容所有VGA/XGA/QXGA 直达监视器、投影机和LCD 屏幕
·能将所有视频卡的识别位连接至本机监视器输出，使DDC1 与DDC2（即插即用）卡和投影机能自动进行分辨率选择
