AC-3 Effects and Parameters
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.
MASTER LEVEL adjusts the output level of the two-channel downmix.
This control should be set to +5dB unless the LFE is very heavy, inwhich
case the level should be reduced.
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.
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.
REAR LEVEL controls the volume level of the rear speakers. Although
we have selected a default value, the correct setting will vary with each
recording, the room, and your personal taste.
SIDE LEVEL controls the output level of the side speakers. Use this
control in conjunction with SURROUND LEVEL to achieve the optimum
balance between the side and rear speakers.
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.
SURROUND EX (available as of software version 4) extracts and
reproduces the additional rear channel mixed into SURROUND EX
encoded soundtracks. This parameter is automatically set to ON when
both SIDE and REAR speakers are selected in the SPEAKER CON-
FIGURATION menu, and will not operate unless SIDE and REAR
speakers are selected. SURROUND EX decoding can be engaged
during playback of non-SURROUND EX encoded 5.1 material, how-
ever, the information delivered to the rear channels may not be pleasing.
SURROUND MIX allows independent adjustment of the level of the
surround channels. Many AC-3 encoded soundtracks sound better
when down-mixed to two channels with the surround level increased by
approximately 2-3dB.
