If there is one subwoofer in the layout, and you have specified the
front speakers as
Small , the subwoofer will be used for the bass
and LFE. If the front speakers are Large and the centre speaker is
Small , the Front subwoofer option allows you to choose from
the following options:
Option Use of subwoofer
LFE Only * Handles just the LFE.
Bass-neutral (centre) Handles all the bass.
Bass-heavy (mono) Shares the bass with the front
speakers.
* Not available for the
Logic
layout.
If the layout includes two or more subwoofers, the subwoofers will
handle the bass and LFE for the system irrespective of the size of
the front speakers.
Specifying the crossover settings
For each speaker layout the Crossover option allows you to set
the crossover frequency for the subwoofers. This is ignored if the
subwoofers are only handling the LFE.
The Meridian digital surround controllers provide very high-quality
crossovers for the subwoofers, and for best results you should
use these instead of the subwoofer’s crossover. To do this set the
subwoofer
Width
property to
Narrow
, and remove any crossover
in the subwoofer, or set it to the highest setting (eg 200Hz). If
you cannot do this, set the subwoofer
Width property to Wide to
switch off the digital surround controller’s crossover and use Sine/
Sub mode to match the subwoofer’s crossover frequency.
The LFE low pass filter option sets the low-pass filter for the LFE
channel, for the Music and 5.1 Movie speaker layouts.
• Click the Reset button to reset the crossover and low-pass filter
to recommended values in all layouts.
Specifying the THX settings
The THX settings tab allows you to specify that your subwoofers
are
THX Ultra2 approved
, and select
Boundary gain
compensation
to reduce bass levels if listeners are close to a
wall. Click the
THX Defaults
button to set the crossover and low-
pass filter to 80Hz in all layouts, as recommended by THX.
