As such, they are produced with two input jacks for stereo operation. Since most manufacturers and customers would question a product with an empty whole in the chassis, they simply fill it with the appropriate jack and tie it into the circuit. Not only does it look better, they can claim "added versatility" as mentioned in the posts above. Sean >

Of course, one could use either (or both) whenever one wanted.
