my D410XLT has two inputs . . . why?

  1. can anyone give me an answer on this? i know my eden WT400 has two outs (4 ohm outs) and i don't think it makes a difference which one i plug into for my outs from the amp, but what about the in's on my 410XLT? it's an 8ohm 410XLT model, btw.

    There are two jacks on most speaker cabinets so they can be "daisy chained": that is, a speaker cable is run from the amp to one cabinet, then another speaker cable is run from the first cabinet to a second cabinet. That way two cabinets can be run from one amplifier output.
    When doing this, caution must be used to ensure that impedance is within the limits for the amplifier, but you could run two 8-ohm D410XLTs from one output jack because two 8-ohm cabinets combine for a 4-ohm load.

    Careful though, combining an 8 and a 4 ohm load will give you 2.67 ohms. Here's the formula:

    If C1 and C2 represent the impedance loads of two speakers (or more), hooked up in parallel.

    (C1 * C2) / (C1 + C2)

    Never give your amp a lower impedance load than it's rated for.
