hall, a dance floor, or virtually any size room at all. This ability to create sound fields at will is exactly what Yamaha has done with the DSP system. DSP programs consist of some parameters to determine apparent room size, reverberation time, distance from you to the performer, etc. In each - Yamaha DSP-A970 | Owner's Manual - Page 42
direct sound. The "ROOM SIZE" parameter provided in many of the DSP programs alters the timing between these reflections, thus changing the shape of the sound, and its control range. 1.
