DC-1Effects

This Effect, available only in DC-1’s equipped with Dolby Digital process- ing, enhances playback of Dolby Digital music recordings, or Dolby Digital film soundtracks with strong musical content. This effect contains many of the features found in 5.1 LOGIC 7, with settings that are more appropriate for music.

AC-3 STATUS displays the current status of incoming AC-3 data. The displayed items are not user adjustable.

COMPRESSION enhances the intelligibility of Dolby Digital material at low volume levels (-6dB or lower). When set to AUTO, this control auto- matically limits peak signals and boosts low level signals. The amount of compression increases proportionately as volume is decreased. This is quite useful when listening to Dolby Digital soundtracks at low output levels. When set to ON, full compression is applied, regardless of volume.

RE-EQUALIZER equalizes the left, center, and right channel outputs to match the overall frequency balance of the original recording. Without this re-equalization, many films and some television programs will sound too bright.

SURROUND LEVEL controls the volume level of the side and rear speakers. Although we have selected a default value, the correct setting will vary with each recording, the room, and your personal taste.

REAR DELAY OFFSET is an additional delay added to the rear channels when listening to LOGIC 7 and MUSIC SURROUND. This delay increases the apparent size of the listening space by increasing the rear delay time. Feel free to experiment to find the setting that works best.

LFE MIX LEVEL allows separate level attenuation of the LFE channel, which is ultimately mixed to the subwoofer output. As the bass from as many as five other channels is added to the LFE, it can significantly raise subwoofer output levels — and create the risk of damage to a system. Careful adjustment of this parameter will allow you to achieve proper tonal balance and reduce the risk of damage.

SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the normal subwoofer level is set during the calibration procedure, with some recordings it may be desirable to increase or decrease this deep bass level.
