(Please note:
If
you
intend to use the ELR265. ELR2100
and
ELR2150
in the Tri-mode
configuration,
it
is necessary
to
set
the
crossover
control
to the
"FLRT"
setting
in
order
to
receive
full
range output)
The
"ELR"
amplifiers
are equipped
with
a
built-in
crossover
network
allowing
you
to select
the
crossover
type
(Le.
Low-Pass
or
Hi-Pass) and the desired
crossover
point. For example
if
you
wish
to
drive
a
pair
of
subwoofers,
you
can select the "Low
Pass"
setting
on
the
amplifier
to
filter
out high frequencies. This
will
send only
low
frequencies
to
your
subwoofers
(see example
settings
below).
Select the
crossover
type
on
the
amplifiers
side panel.
(Low-pass is selected in
this
example
for
subwoofers)

The
ga
ins

it

con
t r 0 I
for
the
"E LR"
amplifier
is located
on
the side panel. This gain
control
has been included to allow adjustment
to
properly
match the output
of
the radio. This is
one
of
the most
misunderstood adjustments.
By
rotating
the
control
in
the
clockwise
direction,
the
amplifier's
input
will
MIN MAX become more
sensitive
and
the music
will
play louder. This is
not
a volume
control
and
you
will
not
get
more
power
out
of
the
amplifier
in the maximum
position!
It may seem to
deliver
more output. but actually the system is only playing louder
faster
as
you
turn
the volume
control
on
the radio. Ideally, to
properly
level match the
system
the goal is to achieve maximum output
from
the
amplifier
without
distortion
at
about
3/4
of
the volume
control.
To
determine
if
the
amplifier's
gain is
set
properly,
turn
the system
on
and
slowly
increase
the volume
control.
You
should
be
able
to
use about
3/4
volume
before
the system gets loud
but
not
distorting.
It is
very
important
when making these adjustments
that
you
do
not
over
drive
the speakers (at point
of
distortion)
this
will
cause permanent damage to the
speakers.
If
you
are unable to achieve
3/4
volume
before
distortion
you
will
need
to
adjust
gain
control
(in
this
case
you
would reduce the gain).
The
gain
controls
should
be
adjusted
very
slowly. It may help
to
have
another
person to
assist
you
by
adjusting the
gain
controls
while
you
listen
for
distortion.
