Query: Not reliable

We have used this product for just over 1 year in our church. Two of the inputs are dead. The effects section is dead. The EQ is not behaving properly (for example, when setting the selection switch so that one set of EQs is for the monitor and the other is for main, only the right speaker comes on, so we are forced to configure the EQs as left/right). The feature set is nice for the price, but not if everything starts failing right after the 1 year warranty is up.
