dsp sound field modes

According to the characteristics of the audio source to its individual processing, coupled with the Yamaha DSP parameter settings, will produce different results, these different results are also different sound field mode. There are several:

(1) Dolby Directional Logic Surround

When the sound track of a movie is recorded in Dolby Stereo, the four channels are composed of the left, center, right, and surround fields, which are then encoded into the two channels. A Dolby Directional Logic decoder decodes and reduces this signal to 4 channels, and after processing, there is a great deal of progress in performance, both in terms of separation, directionality, and movement of sound between channels.

(2) Dolby Directional Logic/Enhanced Mode (35mm Movie Theater Surround Mode)

This original sound field truly reproduces the sound that can only be heard in a 35mm movie theater, the feeling of the scene, and then after the Dolby Directional Logic decoding, it goes into the Digital Sound Processing Line (DSP) to do the enhancement process, so the processed signal will be able to show a The Dolby? DualBIOS? is a powerful, high-performance digital audio solution that delivers up to 5.5 Gbps of audio quality in a single cable.
