With horizontal bi-amping, one amplifier drives the high
pass (ESL) section while the second amplifier drives the
low pass (WOOFER) section. To horizontally bi-amp your
Aerius i’s you must loosen the binding posts and remove the
jumper clips. Connect the low frequency amplifier to the
lower set of binding posts of both speakers. Connect the
high frequency amplifier to the upper set of binding posts.
Next, connect the left and right preamplifier outputs to the
appropriate left and right inputs of both amplifiers (See
Figure 3).
Vertical Passive Bi-Amplification
The very nature of vertical bi-amping dictates that both
amplifiers be identical. With vertical bi-amping, each of
the stereo amplifiers is dedicated to one speaker. For
instance, the left channel of each amplifier drives the low
pass (WOOFER) section while the right channel drives the
high pass (ESL) section. To vertically bi-amp your Aerius i’s
you must loosen the binding posts and remove the jumper
clips from both speakers. Starting with one speaker, connect
the right channel to the lower binding posts and the left
channel to the upper binding posts. Repeat the same procedure
for the other speaker. Connect the left preamplifier outputs
to both inputs of the left channel amplifier and the right
preamplifier outputs to both inputs of the right channel
speaker (See Figure 4).
