The Octo Signal Buffer is an 8HP 8 input, 8 Output buffer and mult module that lets buffer up to 8 copies of a signal signal. Each of the 8 inputs are cascaded allowing you to mult any signal with ease. Each of the outputs is equipped with a bi-polar LED, which is perfect for monitoring the output of each signal. The OSB also features 8 switches which allow you to invert the outputs individually.
