The amplifier-distributor is dedicated to the operation with video and audio signals. It enables the branching of a signal of one source into several consumers with minimum distortion. The modular design makes possible different amplifier versions:
1 x 4 composite video
1 x 4 composite video + mono audio
1 x 4 composite video + stereo audio
1 x 4 Y/C video
1 x 4 Y/C video +
mono audio
1 x 4 Y/C video + stereo audio
1 x 8 composite video
1 x 8 composite video +
mono audio
1 x16 composite video
1 x 4 Y-U-V
