FlatPanel Audio ships our demo systems complete, with the LEA Amplifier installed in the rack case, and the custom patch panel installed in the rear of the amplifier case.
The patch panel has 11 wiring connections in a very tight space, and there are some very specific steps to follow to ensure proper fitment of the wires and the patch panel itself.
