    I understand the impedance problems with basic Y splitters for active lines, but what about passive outputs?

    My situation: We want to run a monitor line to a mixer for the drummer to plug his earphones in to but we're one output short. Can I split the passive output cable going to the powered floor monitor with a Y splitter to run a line to the drummer's headphone mixer without affecting the floor monitor?

    Doesn't the monitor have a 'thru' patch?
     
  3. Yes, it's a line level feed, and it shouldn't affect the powered monitor.

    EDIT:
    ^^^ This, use the thru/out.

    No trouble. Most modern electronic bits can drive a number of devices with little or no reduction in capability. Mics can drive several consoles with no problems.

    Err... When have you run a single mic through a passive splitter into "several" different mixers? Did you mean to say "mic PREAMPS" can drive multiple devices?

    To the OP:
    I think I understand what you mean, but just for clarity's sake, the monitor output is not passive, it is just unpowered. The reason what you want to do WILL work is because that output is active, has low output impedance, and will not be noticeably affected by splitting to both a monitor and a headphone amp. Both devices will work just fine.

    Owing to the signal level of a mic, yes, it would be a mic preamp.

    I misread the question. A mic can feed a number of preamps with no trouble.

    A preamp can feed a number of line inputs with no trouble.

    Get a headphone amp or small mixer with balanced line input ability and patch an XLR to TRS from the powered monitor thru/output jack to a line in (not a mixer XLR mic input) Done

    (Small mixer may work better as you would have some EQ ability if needed and could also use second channel to patch off of FOH mix the same way and blend them if desired by patching from a FOH powered cab or from an amps parallel line out.)

    all the time, a plain ol' SM58 into a splitter cable will drive two mixers easily.
