Review on Enhance Audio Flexibility with ART Splitcom Pro 2 Way Microphone Splitter and Combiner by Brad Collins

If you have a drummer with two kicks but only one kick channel, this will help you a lot. You can even use it to mix two rack mics to save channels. If you play two-key keyboards, you can combine them into one signal to send to the sound engineer. But what makes it really useful is when you use in-ear headphones. You plug your mic into this guy. You connect the FOH mic cable to this guy so the sound engineer doesn't interrupt your signal. You then connect your IEM to this guy to give yourself the exact same signal with complete control. This little box makes life on stage easier. The best secret of stage sound.
