M ORE ON SPEAKERS
Break-In Period -
We recommend that you use your
E
combo at
low
to moderate
vo
lume
levels
for approximately ten
hours
hemselves
and the
speaker
to
break in. This
is
very
similar
in
,
c oncept
to breaking in the
engine of a
new
car. It wil
I
actually take about 24 to 50
hours
of
total
playing
time to fully
break
in your
speaker system
.
If desired, you can
plug
a CD
player
into
your
amplifier and play a CD through your enclosure
to
accomplish this break-in.

With Additional
Cabinets
-
We
des
igned
the
E
series combos to provide
maximum power without the
need
for
additional
cabinets. That's why the
impedance
of
the
internal speakers
is
4 Ohms.
In
order
to
protect
the
amplifier from misuse and
abuse,
the
extension speaker
jack is
wired
in
series,
so
the
amp can't
be
forced
to
operate in
an
unsafe
mode.
What
th
is
means
to the user
is
that, when you connect
an additional cabinet
to your
E
combo,
you will
not
get quite as much
power to
the speakers. However, because of
the
added speaker
s
urface
area, you will still notice an
increase in
volume
-
just
not
quite as much as you
might
expect.
Also,
keep in mind that simply adding amplifier
power
will not
necessarily
increase
your
volume
significantly.
The
addition of more
speakers
will
usually
have more impact on your
overall volume
level
and
improve
your
overall presence
and
tone.
C
abin et
Place
ment
-
The
placement of
your
cabinet
can also
have
an
impact
on
the
amount
of
bass
it
produces.
Placing the
unit
on the floor increases
the
amount of Bass you get
by
an
additional
+
3dB
.
With each additional
wall
surface
placement
you
get
another 3
dB
increase.
This is due
to
the reinforcement of
bass
frequencies
by the
adjacent
surfaces.
The absence of reinforcing
surfaces
is the reason why outside settings are
so
problematic
for
bass amplification. A
system
that
may
be perfectly
adequate in a fairly large
club
can
be
rather
disappointing
on
an outdoor stage.
If
you have plans to perform in
such
a
setting
and are not
confident
that the
P.A.
system can provide
you with
sufficient reinforcement
(both
out front
and
v ia
monitors),
you should
consider using
additional
equipment
to
support
you
r
own
sound
.
O THER
CONSIDERATIONS
Headphone Jack
as
a Line
Driver
-
On
some occasions (such as high-volume or outdoor
situations)
it may be
des
irable
to use your
E
combo along with an additional
power amplifier
and added cabinets.
A
standard shielded
instrument
cable
may be used to connect
from
the
headphone
jack of
the
unit
to
an
unbalanced
input
of a standard power amplifier.
This
will
provide a signal
that is post-EQ
and after
the
Master Volume
control,
allowing
the
entire system
to
be controlled from the E. This
way, you only
have
to adjust one
set
of
knobs.
This is a
Really
Neat
Thing,
huh?
