G65 includes the full range of DSP presets from Meridian, including cinema and discrete, as well as a trifield system setting, which uses the entire surround playback system to bring an immersive listening experience to two-channel content. Trifield fully decodes the stereo stage for left, center and right front-stage loudspeakers, instead of solely left and right, giving it a more stable image.
Meridian says that central to the G65 is its DSP engine made up of five Freescale processor devices delivering 750 MIPS (million instructions per second). All processing is carried out at high sample rates and with up to 48-bit precision, far beyond human hearing. This DSP engine is also responsible for G65’s comprehensive bass management system which can support up to three separate subwoofers, and for managing the up to 60 filters created by Meridian’s Room Correction software.
