DC-1Effects

Music Surround, available in the THX and Dolby Digital versions of the DC-1, is a surround effect developed specifically for music listening. It makes full use of additional loudspeakers placed at the center, sides and rear of the room. This effect passes unprocessed left and right information directly to the front left and right speakers.

CENTER LEVEL attenuates the level of the center channel and can turn it off completely.

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.

SIDE ROLLOFF provides a high frequency cutoff for the side speakers. The optimal setting for this control will vary widely with the source material.

REAR DELAY OFFSET is an additional delay added to the rear channels. 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.

REAR ROLLOFF sets the cutoff frequency of a low pass filter in the rear- channel. Frequencies above this setting are attenuated. This control should be set high enough to give presence and airiness to the rear sound without placing distracting instrumental overtones or other sounds behind you. In systems configured without rear speakers, the settings affect the side out- puts.

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.

EFFECT LEVEL adjusts the loudness of the side and rear speakers. When there are no side speakers, it adjusts the amount of ambient signal mixed into the main loudspeakers.
