This circuit lets you split up an input signal to an arbitrary number of outputs using only resistors. The bad news is there is an attenuation of the signal. Enter the desired impedance and the number of outputs to find out the correct resistor value and the attenuation.

If you want to attenuate a differential signal just use resistors in both legs - and divide the series values by two.
Here is an alternate attenuator form. Change any value and the other three values will change as well.
