A typical headphone cable is low impedance. So, if you plug one into a normal “Y” cable it would act like a short circuit to the other instrument. All you would hear is the music player. The IA-303 package allows you to hear both the instrument and the music player at the same time. The IA-303 system allows you to connect one instrument and one portable music player into one 1/4" phone jack input on your instrument amplifier. Simply plug in your instrument and music player and balance the volume using the normal volume controls on your instrument as well as on the music player. The special circuit will combine the signals without the problems found using a typical Y-cable. This keeps interaction between the instrument and music player at an unnoticeable minimum and adjusts the volume to match what you would find with a typical single instrument. The included music player adapter is used to connect the 3.5 mm plug into the output from a normal portable music player output jack and the other end is connected into one of the GA-101 adapter jacks. Package includes one GA-101 adapter cable and one IC-31 portable music headphone adapter.
