Default Passive Line Splitter

Does anyone know how can I split the line output from my mixer to drive separate sets of power amps?

Thanks,
Simon

Buy a Y-splitter lead, commonly available. How many power amps though?

Just two amps. Wouldn't it be better to use transformers?

add a second output terminal to your mixer.
Connect the grounds of the two output together.
Disconnect the existing output lead and insert a 100r resistor and resolder to the Hot feed of output1,
Take a second 100r resistor and solder one end to hot of output2. solder the other end of resistor2 to the far side (feed side) of resistor1.

You now have a mixer with two outputs, use none, or one, or other, or both.

Similarly, you can add a second input terminal to each of your amplifiers. this time connect the input ground together and connect the input hots together.

You can now daisy chain your power amps.
This covers all eventuallities. But remember your source (mixer) is effectively driving all the cables and all the input impedances of the receivers in parallel. The mixer will need a good buffer on it's output.
If it can already drive a 600ohm connection then the buffer is already fitted..

Two amps should be fine as the loading will not be too much. The issue may be one of grounding and yes transformers would be better in this respect but a pair of good transformers is going to cost you in the region of 100 pounds and then you have to enclose and wire them.
