I have two audio amplifiers (one for bass & one for mid/highs), however I only have one RCA source from my CD player, and would like to split it.
I heard there was a loss in signal if I simply split the original signal, is this true?
It's all to do with impedances - a preamplifier (or CD player) should have a low(ish) impedance output, and an amplifier should have a high(ish) input impedance.
The output impedance of the CD player, and the input impedance of the amplifier form a potential divider - this reduces the output by a certain amount, which should be negligible. Adding a second amplifier puts the two input impedances in parallel - giving half the impedance, this will cause the output to fall by another small amount - but again, this should be negligible.
For your purposes it should work fine, and you shouldn't notice any difference between one or two amplifiers connected.
