SDP-40HD Mode Adjust

CONCERT HALL

MODE ADJUST CONCERT HALL

The CONCERT HALL mode generates early reflections and sends them to all speakers except for the LFE speaker.

The CONCERT HALL mode is a superior room simulation listening mode because it uses a proprietary reverb algorithm that is relied upon by a majority of recording engineers to add ambience to recordings.

The CHURCH mode uses a reverb algorithm to emphasize the rich, smooth, reverberant decay characteristic of small and medium listening spaces with long reverberation time relative to their size, such as churches and chambers.
