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 conguration.
When congured 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
amplier 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 dierent ampliers on each
speaker, the ampliers 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 ampliers have the same gain
and may be used in any combination for bi-amping.
NOTE: When the ‘Bypass’ Output Conguration is selected, the
Aux channels will output full range signals as L&R channels,
overriding any other conguration setting that might otherwise use
Aux 2 as a second subwoofer output. e DSP would unavailable
in Digital Bypass.
