Wantind to add mics to my karaoke machine-Vocopro GiGMan karaoke system
I'd get a small mixer, then run mics into that, mix em down to 2 channels then send em to the karaoke machine, that way you have control in mixing multiple mics down to 2 channels, I wouldn't bother with 1/4 " mini plug mics or splitters personally.
A D.I. box ( direct injection ) takes an instrument or line level signal through a step down transformer and it comes out the other end as a mic level signal, the purposes of it are for running an electric instrument into it wich is split into 2, one for going to the input stage of a mic pre, the other can go back out to an instrument amplifier, this way you can run a direct signal into the console via " direct injection " into the mic pre as a mic level signal and also can run it to your instrument amplifier in order to be able to also mic the speaker cabinet acoustically at the same time, there are many benefits to this, for instance in live shows if the speaker cabinet or mic fails then you still have the direct signal, also since the direct signal tends to be punchier and clearer, cleaner, than an acoustically mic'd signal, they can both be mixed together at the console to give a a desired blend of each signal. Since there is a small delay between the direct signal and the acoustically mic'd signal because of distance of the mic from the soundsource delaying the direct signal a bit may be desired.
D.I. boxes are only for instruments, they are superflous for vocals, the quality of the D.I. box does matter and active D.I.'s are the way to go, passives are as they are in speaker crossovers, less than desirable quality.
There are also many tube D.I. boxes, generally a D.I. box isn't necessary for running an instrument into a consoles mic pre because most consoles take line level inputs as well, and there are other ways for getting a line level signal into a console by bypassing the mic pres anyways, If you have quality mic pres it's good to use them for the initial gain stage though as opposed to boosting instrument level to line level using a crappier preamp, for instance running an electric instrument input through an effects pedal will raise the instrument level to line level but of course an expensive mic pre will do a better job of it than an effects pedal will, since the first gain stage is paramount to quality......................
