Table 4 - Available configuration settings for front L/R speaker Butterworth crossover.
Press

speaker. This submenu is shown in figure 28.
Center Speaker Configuration
Figure 28 - Front Panel Display of the SETUP / INP / CONFIG / CENTER Submenu
This submenu of settings for the Center speaker is virtually the same as the one for the front left/right speakers, with
two additional options. When the
CFG setting is set to XOVER or FUL/LP , the low pass signal from the crossed over
center will be routed to the sub, if one sub exists, or front left/right subs if there are 2 in the front. This same low pass
signal can alternately be routed to the front left/right speakers if the
CFG setting is XOVRLR . If the center low pass
signal is routed to the front left/right speakers, and these front speakers are crossed over, the low pass signal from the
center stays routed to the front left/right speakers and the low pass signal from the front left/right will then be routed to
the subs. If the
#SUBS is set to 0 and the front left/right CFG is set to XOVER , the low pass signal of the front left/right
will be lost.
Routing the center low pass to the front left/right speakers can be useful with center speakers that have a limited bass
response (-3dB @ 100Hz). In this case, the recommended crossover frequency should be set to 160Hz.
If no center speaker is present in the system, the CFG parameter should be set to PHANTM (phantom). With this
setting, the center channel signal is routed to the front left/right speakers. When the center CFG is set to PHANTM ,
the user has the ability to adjust the level of the center channel in the front left/right speakers. This can be
accomplished via button #
6 – PHLVL (phantom level).
Note : The phantom ( PHTM ) setting for the center speaker creates the illusion of having a center speaker when the
listener is positioned equidistant from the front left and right speakers. There is, however, no substitute for a real
center speaker as it creates a solid center image even when the listener is positioned off-axis. The phantom setting is
most useful on video sources where a more prominent center image is desirable and no center speaker is present. On
music sources,
OFF may be the preferred setting as it maintains the imaging properties of the original source.
Pressing button # 1 allows the configuration of the center speaker. If this speaker is not to be crossed over, then the
CFG should be set to FULL . There is an option where the full range signal can be routed to the center speaker with
the low pass part of it also routed to the sub ( FUL/LP ) or the high pass signal going to the center and its crossed over
low pass portion being routed to the front left/right speakers as discussed above ( XOVRLR ). Whenever any speaker
is crossed over, a crossover type must be selected, and the appropriate crossover frequencies and slopes set.
The center speaker can also be set to XOVER or OFF . In the case of OFF , any center channel information will be lost.
Press button # 2 , 3 and 4 to set the crossover settings for the center speaker in the same manner as with the front
left/right. The crossover menus are the same, with the exception of the speaker name in the upper right corner of the
