ESP-3 AUDIO WIRING
Center Channel Speaker Considerations. Key to the
ESP-3's
Image Amplification
process
is
an additional center channel speaker. Your choice of speaker should be a
function of the following considerations (does that sound official or what?). It should be:
•In
the center. This may sound like we're stating the obvious, but the center channel
MUST
be placed in between the left and
right
front speakers. It "anchors" the stereo image
and
if
you skew center channel to either side, the whole gigantic Spatially Restored, Image
Amplified sound will be out
of
whack.
•
As
large
as possible. Center channel information is definitely FULL range. So,
within reason, you should use a full-range center speaker. The absolute smallest would be a
4 incher (some claim to go down to 90 Hz but we don't believe
it).
5-inch or 6x9 coaxial is
far better. We've made things easier by including a PFM filter which acts as a low-cut
filter, but the speaker should be capable of strong output right down to the cut-off fre-
quency. We said "largest within
reason"
because another
factor
enters
in
...
• Placed as up
front
as possible. Because the center channel
is
full range
it
contains
treble which doesn't fare too well if its playing at the listeners' knees. Obviously larger
speakers are harder to mount high up in the center.
•
Finally, the speaker should have the same sonic signature as the left and right
speakers. In other words,
its
frequency response should resemble that of the main speakers.
If
you have carbon fiber tri-axials with titanium tweeters on the sides, don't use a cheap,.
mushy cardboard cone "full
range"
in the center
-
it won't have the same mid and high
response. If you have separate mid/woofers and tweeters
on
the sides, consider
*e
same
for
the center if there's room.
Amplifier Considerations. The ESP-3 creates the need for an extra amplifier charmel.
If you had two before you'll need three. If you're running the ESP-3 with a really
compli-
cated multi-amp system, we'll leave you to your own mad-scientist
plans.
But
if
the ESP-3
is part of a smaller system (one
with
just front left, front right and subwoofer, for example)
you might consider taking advantage of a 4-channel amp. If the
.lfVOOfer
isn't
too
big, you
can run left, right, center and subwoofer off one channel
each.
The
other
option
is of course
to
devote a whole amp to the center channel.
If
this is the case, just size it so
it is
driven by
about the same power as the left and right front
channels.
For
example, if the left and right
speakers are being driven by 50 watts, select a 50 watt amp.
Or
use a 25-watt amp and
bridge
it.
The ESP-3's THRU Connections. Along with the regular INPUT's and OUTPUT's,
there are left and right THRU sockets. These are really two more OUTPUT's except that
the ESP-3's circuitry doesn't affect their sound. This is so you can drive other sets of
speakers where you don't want the spatial restoration effect without resorting to "Y" cords.
Center Channel Outputs. They're both the same output and are mono, so don't
entertain
ideas
about trying to get a stereo center channel or anything like that. We
provided two to give you additional flexibility in sophisticated, multi-channel installations
like the example below.
Planning
Your
Hook-up
Strategy. Okay,
time
to trot out the
flow
charts and
diagrams. Naturally, there
are lotsa
ways to hook up the ESP-3, depending on what the
rest
of
your system is like and whether
you
choose to use the
THRU
connections.
