Emphasize dialogue and vocals with the TX-SR3100’s Vocal Enhancer technology.

Our Music Optimizer DSP listening mode reconstructs data that can be lost when audio files are compressed (which can happen with WMA, AAC and MP3 formats). This technology brings audio files back to their original lossless quality by creating new signals to restore minor details left out during the compression process.
