In a bi-amping arrangement the signal paths for the bass
and mid-range/treble ranges are separated before they
reach the power amplifiers.
In the horizontal bi-amping version, one stereo power
amplifier is used to amplify the bass range for both
channels, while a seco nd stereo power amplifier drives
the mid-range/treble range of both channels.
Advantage: symmetrical load on the power ampli fier
mains power supply for both channels.
Disadvantage: the power amplifier determines the
channel separation.
The bridge pieces between TT and
MT/HT must be removed!
In the vertical bi-amping version the power amplifiers
work in a strictly channel-separate arrangement.
One stereo power am plifier amplifies the signals for o ne
loudspeaker: one channel drives the treble/mid-range,
the other channel the bass range.
Advantage: maximum channel separatio n in the power
amplifiers. Power ampl ifiers can be located c lose to the
speakers, therefore short speaker leads can be used.
Disadvantage: asymmetrical load on the power amplif ier
mains power supplies due to bass processing on one
side and mid-range/treble processing on the other.
