This works fine. I used to split my preamp signal and send it to the sub x-over as well as the main amp. I added another set of outputs so, I no longer use the Y cables.
Using Y-adapter to duplicate preamplifier outputs
Is there any loss from using y-adapters to duplicate an output on an amplifier? Case in point; I want to duplicate my preamp output to feed a ss amplifier and a tube amplifier. Both will not be used simultaneously. I just don't want the hassle of having to remove interconnects each time I am going to use one amp or the other.
