If you also want to High-Pass Filter the L&R outputs, check the box for L/R
HP Filter. The crossover will pass the higher frequencies and correctly direct
the low frequencies to the subwoofer(s) based on your frequency and slope
settings. If this box is unchecked, L&R channel signals pass full range and the
lower frequencies are duplicated by the subwoofer(s). This may result in too
much bass, especially at certain frequencies, so equalization may be required to
compensate.
The CP-800 has two auxiliary channels that can be utilized for bi-amping the
L&R speakers. Alternatively, Aux 1 may be used in conjunction with the Sub
output to provide a second mono subwoofer or stereo subwoofer configuration.
If either the single-ended or balanced Aux channel outputs are enabled and no
more than one subwoofer is being used, then the aux channels are considered to
be active in bi-amp mode. Technically, this is called power-biamping. Separate
amplifier channels are used for the high and low frequency drivers of your
loudspeaker, but the passive crossovers in the speaker do the work of filtering low
and high frequency signals. In this mode, the two auxiliary channels produce the
same output as the Main Left and Right channels.
NOTE: When bi-amping with two different amplifiers on each
speaker, the amplifiers must have the same gain in order to ensure
proper level matching between the upper and lower frequencies. All
Classé Delta and CT series amplifiers have the same gain and may
be used in any combination for bi-amping.
The Display Setup menu page, shown below, allows you to configure the
brightness and display timeout used for the touchscreen display.
