1. Vertical Biamping
Vertical biamplification requires the dedication of a single stereo amplifier for
the left speaker, and another stereo amplifier for the right speaker. This con-
figuration improves channel separation and can improve imaging slightly.
2. Horizontal Biamping
Any two stereo amplifiers may be utilized in horizontal biamplification. Many
audiophiles prefer the "sweetness" of tubes on the satellite portion of the
loudspeaker while favoring the "control and weight" of solid state amplifiers
on the bass section. The biggest drawback of such a marriage of amplifica-
tion is that the two amplifiers may have different input sensitivities or output
polarities. Small differences in the input sensitivities may be overcome by
using the Whisper Processor. It's also a good idea to check the owner's
manuals to establish if the amplifiers are inverting or non-inverting. If the
two amplifiers are of opposite polarity, then you should reverse the polarity
at the inputs of either the subwoofer or satellite binding posts.
NOTE: This only applies to loudspeakers that incorporate the subwoofer and
satellite section in a single enclosure. It does not apply towards the separate
powered subwoofer/satellite configuration. You must always observe the po-
larity when connecting the speaker wire to a powered subwoofer.
