Most quality loudspeakers have two or more sets of input binding posts for
connection to the amplifi er. These separate the signals that are going to the
woofer(s) from the signals going to the tweeter (and sometimes a third set of
speaker wires isolates the signals going to the midrange). Normally, there are gold
or tin plated metal shorting straps connecting the single speaker wire to both the
low and high range drivers on each speaker.
As the speakers vibrate to reproduce sound coming from the amplifi er, the drivers
also act like small generators, creating a signal of their own, which is forced back
down the speaker wire. This is called back emf. The woofer, due to its cones' larger
moving mass, generates the bulk of back emf. This relatively messy signal mixes
with the more delicate midrange and tweeter signals on the speaker wire and has
the net effect of clouding the sound.
At minimum, you could run separate pairs of speaker wire to each input on the
back of the speaker. This is called bi-wiring. Your dealer can confi gure special
cables that have four separate connectors at the speaker end, and are joined into
two banana jacks at the amplifi er end. The sonic improvement in a bi-wired
speaker over a single wired speaker can be noticeable. This isolates the back emf
from affecting the signal in each speaker wire, but still combines the wires at the
amplifi er end and mixes the back emf with the pure signal coming out of the unit.
However, some improvement in sonic clarity is gained due to the low output
impedance of the Cinepro.
Clarity is markedly improved by BI-AMPLIFYING
When you bi-amplify your speakers, you gain complete isolation of the woofer
signals (and its back emf signals) from the midrange-tweeter signals. Each speaker
element (woofer, midrange/tweeter) is driven by its own amplifi er channel.
This has the additional advantage of relieving the power amp of the duties of
reproducing very low bass notes and the delicate high frequencies at the same time.
The amplifi er is able to "split the task" to two separate channels, and a cleaner,
more relaxed sound is the result.
In addition, instead of just 475 watts of available power to each speaker, you
now have 950 watts of pure power on tap. This, of course, allows more dynamic
reproduction during very robust music and special effects passages.
Hook up is quite simple. First - Remove the shorting bars from the back of
the speaker. Then, hook up a separate speaker wire from channel 1 to the high
frequency inputs on the speaker, and yet another separate speaker wire from
channel 2 on the amplifi er to the low frequency inputs on the speaker. Repeat this
for each individual loudspeaker in the system that you wish to bi-amplify. Use an
RCA "Y" adaptor to feed each two channel pair from one preamplifi er source.
With the six channels available on the 4K6 MK-4 SE-Gold, you can fully bi-
amplify three speakers in your system. For example: front left, center, and front
right. With an additional 4K6 MK-4 SE-Gold, you can power 4 surrounds and 2
passive subwoofers, using 12 channels total.
TRI-AMPLIFYING
Tri-amplifying is the very best possible hookup. This is only available to you if
your speakers have three sets of speaker input terminals. To tri-amplify, simply run
an additional and separate speaker wire from a third amp channel to the tweeter
inputs on the back of the speakers (if available). Please call us at the factory for
more information.
