Bass Management If you also want to High-Pass Filter the L&R outputs, check the box for L/R
HP Filter. e 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). is may result in too
much bass, especially at certain frequencies, so equalization may be required to
compensate.
Auxiliary Channels e Delta PRE has two auxiliary channels that can be utilized for bi-amping the
L&R speakers. Alternatively, Aux 2 may be used in conjunction with the Sub
output to provide a second mono subwoofer or stereo subwoofer conguration.
When congured for Stereo Subs, the Sub output channel serves as the Right
Channel Sub and the Aux 2 output channel serves as the Left Channel Sub.
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-bi-amping. Separate
amplier channels are used for the high and low frequency drivers of your
loudspeaker, but the passive crossovers in the speaker do the work of ltering 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 dierent ampliers on each
speaker, the ampliers must have the same gain in order to ensure
proper level matching between the upper and lower frequencies. All
Classé Delta, CT and Sigma series ampliers have the same gain
and may be used in any combination for bi-amping.
NOTE: When the ‘Bypass’ Output Conguration is selected, the
Aux channels will output full range signals as L&R channels,
overriding any other conguration setting that might otherwise use
Aux 2 as a second subwoofer output. e DSP would unavailable
in Digital Bypass.
