Sunfire home theater processors and receivers have a bass management sys tem that allows you to redirect the bass frequency range of each channel to the subwoofer The advantages are The overall bass of the system is improved as subwoofers such as Sunfire s powered True Subwoofers are specially designed for this frequency range e 1116 subwoofer can simultaneously play the bass from all of the loud speakers in addition to it s own low frequency effects channel LFE There is no loss in perception of the position of movie or music sound effects as the ear cannot easily locate the position of bass sound sources e Compact loudspeakers can be used for front center and sur rounds as they do not have to reproduce the low frequency range This leads to a saving in room space e Your amplifiers do not waste power reproducing the low frequency range Sunfire User s Manual Crossover adjustment We recommend that you set your home theater processor s crossover to 100 Hz and set the channels that use the Cinema Ribbon loudspeakers to small Your subwoofer receives frequencies below 100 Hz from all loudspeakers whose size is set to small in addition to the LFE channel 20 100 20k Frequency in Hz All loudspeakers set to small receive frequencies above 100 Hz Louder Output level dB Quieter Set your subwoofer s own crossover control if it ha

4. trouble free operation Sunfire has found that our ears are very sensitive to certain frequencies which our brains use to develop clues as to the size and location of sounds Bob Carver and team created an electrical circuit called Sonic Holography back in the 1970s that took this into account and to this day it s included on Sunfire s processors and receivers In the CRM 2 Cinema Ribbons these critical octaves are output primarily from the two side firing drivers This introduces the room as part of the musical instrument by intentionally bouncing the sound off of walls and floors creating a time delay to enlarge the sense of acoustic space in all dimensions This is a noted difference from what we looked at previously with the ribbons it is a very calculated and very important distinction The CRM 2C features front firing drivers to maintain focus for dialog in center channel ap plications Conclusion The combination of a focused front firing ribbon and the omnidirectional side firing woofers creates a large sense of space with very precise imaging within that space Depending on the loudspeaker location and demo material you also are able to discern a sense of front to back depth with layered textures of musical instruments playing and performing in thin air Happy listening 4 Sunfire User s Manual Rear Panel Features 3 1 Boundary Compensation Switch This switch
