Figure 3. Bi-wire connection. One channel shown.
Please take note of the jumper clips installed under the
binding posts. These clips attach the high and low frequency
sections of the crossover together. Leaving these in place,
connect the (+) wire from your amplifier to either red
binding post and the (–) wire from your amplifier to either
black binding post (see figure 2).
Bi-Wire Connection
This connection method replaces the jumper clips installed
under the binding posts with individual runs of speaker
wire from your amplifier. This doubles the signal carrying
conductors from the amplifier to the speaker, thus direct-
coupling each portion of the crossover to the amplifier.
To bi-wire you must first loosen the binding posts and
remove the jumper clips. Connect one set of wires to the
upper set of binding posts which connect to the panel of
the Ascent i. Then connect a second set of wires to the
lower binding posts which connect to the woofer. Next,
connect both sets of wires to the appropriate terminals
on your amplifier. Please take care to connect both (+)
wires to the (+) amplifier terminals and both (-) wires to
the (–) amplifier terminals. This is known as a parallel con-
nection (see figure 3).
Passive Bi-Amplification
For those that desire ultimate performance, the Ascent i may
be passively bi-amplified using the existing internal passive
crossover elements.
WARNING! Only after jumper clips are removed
may you connect individual runs of speaker cable
from your amplifiers to the high pass (ESL) and
low pass (WOOFER) signal input binding posts.
Damage will occur to your amplifiers if the jumper
clips are not removed.
This method takes the bi-wiring concept one step further.
You will have a dedicated channel of amplification directly
connected to the high and low pass sections of the Ascent i
crossover. There are two different methods for bi-amping
with two stereo amplifiers. The first and most common is
referred to as Horizontal Bi-amping. The second method is
referred to as Vertical Bi-amping. With either method you
may use two stereo amplifiers or four mono amplifiers, or two
mono amplifiers and one stereo amplifier. Get the idea?
With either form of passive bi-amplification, your pream-
plifier must have dual outputs. If your preamplifier is not
so equipped, you must either purchase or construct a “Y”
adapter.
Horizontal Passive Bi-Amplification
Horizontal bi-amping allows you to use two different types,
models or brands of amplifiers (i.e. tubes on top, transistor
on the bottom). However, we recommend that you use two
identical amplifiers (i.e. same brand and model). If you
must use two different amplifiers, it is essential that they have
the same gain or that one of the two have adjustable gain
so that you can match their gain characteristics. If the ampli-
fiers of choice do not have the same gain characteristics,
then a sonic imbalance will occur. With horizontal bi-amp-
ing, one amplifier drives the high pass (ESL) section while
the second amplifier drives the low pass (WOOFER) section.
