4.7.3.6 Low Pass to Other Speaker
Certain speakers have an option to have the low end cross with another speaker, instead of a subwoofer.
This may help to keep the positioning of the speaker's low end sound, and also to avoid a large number
of speakers being crossed with the subwoofers. This can only be done if the corresponding speaker is
defined as a large speaker.
The following speakers can be crossed to other speakers:
Ls/Rs may crossed to L/R
Lb/Rb may be crossed to L/R
HL/HR may be crossed to L/R
HC may be crossed to C
T may be crossed to L/R/Ls/Rs.
4.7.3.7 Phantom Center Option
The Phantom Center option allows you to direct the Center channel to the Left Front and Right Front
speakers if there is no Center speaker. There is an offset configuration used to increase or decrease the
Center channel level. Note that 0dB offset is the default and includes the 3dB signal level attenuation
needed to account for the sound being sent to 2 speakers.
4.7.3.8 Phantom Surround Option
The Phantom Surround option allows you to direct the surround channels to the front speakers. This is
used for an installation without the surround channels. The Left Surround channel will be mixed into the
Left Front channel and the Right Surround channel will be mixed with the Right Front channel.
4.7.3.9 HP/LP Filter
The slope can be set at either 12dB/octave or 24dB/octave. The cutoff frequency can be set between
31Hz and 160Hz.
4.7.3.10 Offset
The offset control appears only for phantom speaker options. It allows the level for that speaker to be
adjusted before being mixed with the Left or Right speaker. The offset level can be adjusted from +3dB
to -10dB.
