The i-Kenny Kable is made to connect the headphone output from an Ipod type device to the input of any Shure wireless belt-pack transmitter. Originally developed for marching band directors to use their iPhone-based metronome with the sound projections sound machine, freedom, or voice machine models wirelessly. This 28 long stereo mini to TA4F (mini-XLR connector) includes the necessary mono-summing network to properly sum the L/R signal while protecting the headphone output from being shorted out (by using a Y adapter, a very bad idea that can let the magic smoke out of your phone). Connect your Ipad and Iphone type devices to your sound system (wireless mic) transmitter and rock on! Will work with ANY jambox, laptop, MP3 player, phone, etc. that has a 1/8 (3.5mm) headphone output jack. SHURE BELTPACK AND IPOD NOT INCLUDED. YOU ARE ONLY PURCHASING THE CABLE.
