  1. Yep. For the few months that I was auditioning subwoofers in my home audio system, until I moved them on in April of this year, I used a couple of RCA line/cable splitters from the ‘Tape Out’ on the back of my integrated amplifier & both active subwoofers were still able to operate all the way to their maximum output without any problem.

  2. My DAC has one pair of RCA outputs. I split the signal with a Y splitter to feed an amp and a self-powered sub-woofer. There is no loss of sound quality or signal strength. I don’t know if the writer has or would find it possible to try a different set of RCA outputs in the preamp.

  3. I’ve observed a 3db difference splitting XLR to monitors. Or my monitors anyway (Mackie’s). Perhaps this is just the luck of the draw with impedence differences on the in/out. I don’t believe I lose signal detail when this is done. As I understand, this is splitting a 6 volt signal and each half has more than enough current to keep from compromising signal…aside from pure volume level.

  4. When I listen to headphones through a receiver, I have the volume to my satisfaction. When using a splitter and adding another set of headphones, hence two headphones listening to same piece of music at the same time, the volume is much less per set of headphones.

  5. Perverse, moi?
    Schiit have a passive splitter, SYS.
    Almost everyone uses it ‘Two in > one out’
    But why not use it giving two out, like in todays question.

    In my setup it feeds two headphone amps; Stax or normal.
    (I got back an ok when I checked with Schiit).
