Stereo 3.5mm Monitor Splitter Cable

This Male 3.5mm TRS to Dual Female 3.5mm TRS cable provides a headphone monitoring connection at the sound source output.  The second port of the splitter connects to the Line-In on any mc_PuP handheld Mixer. 
The headphone monitor is essential for mixing live vocals or instruments with the sound source when the downstream path to the speakers is subject to excessive delay.  Excessive delay can come from wireless audio connections, digital signal processing, or just the delay of sound waves returning to the performer from the speakers in a large venue.
