Figure 29 - Front Panel Display of the SETUP/INP/CONFIG/LT/RT/Link-R Sub Menu Press button # 1 and select a Linkwitz-Riley crossover frequency for the front left/right speakers, then button # 2 to set the high and low pass slope. Button # 3 allows the user to invert the low pass phase from 0 (+) to 180 degrees out of phase.

Press SETUP once to return to the front left/right configuration sub menu, then press button # 4 (BWORTH) to set up the Butterworth crossovers. This submenu is shown in figure 30. Figure 30 - Front Panel Display of the SETUP/INP/CONFIG/LT/RT/BWORTH Sub Menu Press button # 1 and select a Butterworth high pass crossover frequency, then button # 2 to set the high pass slope. Press button # 3 to set the low pass crossover frequency, then button # 4 to set the low pass slope. Generally speaking, the high and low pass crossover frequencies should be the same unless compensating for unique room or speaker characteristics. Button # 5 allows the user to invert the low pass phase from 0 (+) to 180 (-) degrees out of phase. 52 AVAILABLE SETTINGS BUTTON 1 2 3 4 5 PARAMETER FR-HI FR-HI-SLP FR-LO FR-LO-SLP LP 40 6 40 6 50 12 50 12 + 63 18 63 18 80 24 80 24 100 100 125 125 160 160 Table 4 - Available configuration settings for front L/R speaker Butterworth crossover. Press SETUP twice to return to the speaker configuration sub menu, then press button # 2 (CEN) to set up the center speaker. Center Speaker Configuration Figure 31 - Front Panel Display of the SETUP/INP/CONFIG/CENTER Sub Menu This submenu of settings is virtually the same as the one for the front left/right speakers, but applies only for the center speaker. All of the same guidelines and procedures apply except for the case where no center speaker is present and the destination to where the low pass signal (if the center speaker is crossed over) can be routed. In this case, the low pass signal from the crossed over center will be routed to the sub, if one sub exists or front subs if there are 2 in the front, when the CFG setting is set to XOVER or FUL/LP. 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 still 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 since it has no where to go. This can be advantageous if the user wants to roll off the low pass signal to the front left/right speakers at a very low frequency. Routing the center low pass to the front left/right speakers can be useful with center speakers that have a very 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 signal for the center channel is routed to the front left/right speakers.
