I’m wondering if it is possible to split the L/R of an external device (e.g. MP3 Player) such that a click track is on R and only goes to the monitors and the R is a backing track that can go to the mains.
You could plug it into two separate mono channels…

Just obtain a 1/8-inch stereo plug to 2 quarter-inch plugs and connect the player to two mono channels, as Chris suggested.
…and cross fingers that channel separation is good enough to not hear the click on mains.
