To horizontally bi-amp your Ascent 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 4).
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 Ascent i’s
you must loosen the binding posts and remove the jumper
clips from both speakers. Starting with one speaker, con-
nect 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 pream-
plifier outputs to both inputs of the left channel amplifier
and the right preamplifier outputs to both inputs of the
right channel amplifier (see figure 5).
Active Bi-Amplification
We do not recommend active bi-amplification of Ascent i.
The internal crossover can not be bypassed. This connec-
tion method seriously degrades the Ascent i’s performance.
Bass Control Switch
On the rear panel of the Ascent i electronics module, beside
the signal input binding posts, is a two position Bass Control
switch that allows you to select the type of low frequency
response you desire.
The flat position is considered the normal setting for most
rooms. However, if you feel that the bass in your system
is
too heavy relative to the mid and high frequencies,
simply
select the –3dB position. This switch position will decrease
the output of the woofer by 3 dB.
Some experimentation with these two switch settings will
allow you to find the optimal tonal balance for your specific
taste, room and equipment.
