DTS Effects and Parameters

DTS THX (Including Surround EX)

This Effect provides THX 5.1 AND Surround EX enhancements for film soundtracks recorded in the DTS format. This processing compensates for the acoustical differences between large mixing theaters and the typically smaller home environment. When SIDE and REAR speakers are selected in the SPEAKER CONFIG menu, SURROUND EX is automatically set to ON for proper decoding of Surround EX soundtracks.

Parameter	Initial Value	Range
SURROUND EX	ON	ON, OFF
RE-EQUALIZER	ON	ON, OFF
LFE MIX LEVEL	+0.0dB	-20.0dB to 0.0dB
SUBWOOFER LVL	+00dB	OFF, -30dB to +05dB

DTS Effect Parameters

BASS ENHANCE derives stereo bass to provide low frequencies that are noticeably less localizable and more spacious in the playback room.

Note that results will vary depending on room acoustics and the low frequency capacity of the surround speakers. As side and/or rear speakers are used for bass enhancement, the effectiveness is im- proved with speakers capable of reproducing reproducing low frequen- cies (LARGE). Using speakers that are not capable of producing low frequencies (<80Hz) may cause damage to them.

CENTER MIX adjusts the level of the center channel applied to the two- channel downmix. The appropriate value for film is 16. The appropriate value for music is 11.

CENTER DLY SAMPLES adjusts the time offset of the center channel. The appropriate value is +0 unless you know that the center channel is not properly timed, as well as the amount by which it is off.

MASTER LEVEL adjusts the output level of the downmix. This control should be set to +5dB unless the LFE is very heavy, in which ase the level should be reduced.

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.
