My audio mixer comes with only one pair of mono phone jacks, which internally in the audio mixer are wired to come out as a stereo signal that goes to the computer on a USB cable.
The piano also has a stereo output that come out on two mono phone jacks, which appropriately go into the audio mixer's two mono phone jacks and all this works fine, stereo recording is achieved by the computer.
However every time I need to add another intrument to the mixer, such as a guitar, bass or micorophone that have mono phone jacks, I have to disconnect the piano (at least one side of stereo), which is annoying.
I would like to have all the instruments connected at the same time.
What would happen if I added two mono y-connectors to each of the audio mixer's jacks, then connected two mono instruments to these two available mono jacks?
In this situation, the left piano jack would share the left audio mixer's jack with a mono instrument and the right piano jack would share the right audio mixer's jack. For a total of three concurrent instruments, i.e. one stereo piano and two mono instruments.
Would these mono instruments interfere with the piano's stereo sound? Would all the instruments lose sound level or quality or damage each other?
Indeed the mixer has two mono inputs. But it also has midi jacks, so for now I will change my configuration and have the stereo piano go through midi cables and use the two input jacks for the bass and the guitar. Not my favorite selection of piano sounds, but still good enough for now.
This way each instrument gets its own track and gets recorded concurrently.
My concern is not only about distortion or loss of sound, but I need to know if the y-connector configuration would actually damage the mixer, or even worse, the instruments sharing the same jacks.
