One of the great things about the REL's is they are very easy to integrate with any system and any listening room. They operate with your speakers. They can be adjusted at 1 Mhz intervals. There is no crossover between the preamp and power amp cutting off and or changing the signal to the main speakers. The high and low inputs can be adjusted, and both be set up so you can easily switch from Audio (high input) to Home Theater (Low input) if you have a dual purpose system.
