It is possible to Y-Split data entering pixel strip to duplicate the signal on a synchronous onto more than one length of strip to reduce the number of controllers required.

Note that this results the content on each pixel strip being identical.

To reduce the impact of noise generated in the cable or data bounce back. It is recommended to split the data cable as close to the Pixel strip as possible. – As with any pixel installation, data cabling should be kept as short as possible.

Always test your proposed setup ahead of rolling it out on an installation.
