Sure it came with a crossover all the USA series from USA-400 up to the USA-6000 came with sub HZ control 5HZ to 500HZ and the USA-800 also came with a bass slope control witch I have never seen on any other USA series amp. It also came with a defeatable subsonic filter.
I have to agree with helotaxi i know for sure that the black 1999 model usa-400 amp does not have a crossover! Im look'n at mine wright now. maybe the newer ones do, but they are also a lot lower wattage than the 99 model!
USA - 800
