First off, I don't own one. However, you can check on whether the meters are connected properly by making sure that your connections from your preamp are correct, and then turning the balance control on your preamp all the way to either the right or left, and put on some music. The meter on the left side should move if you have turned the balance all the way to the left, and the one on the right should move if you turned the balance all the way to the right. This is also assuming that your preamp has not been improperly wired

. If the wrong meter moves, then something is wired improperly.
