RND BENEFITS
DC
Offset
Protection
This
circuit
protects the output
of
the amplifier against
DC
voltage.
If
for
some
reason
DC
voltage is detected at the output stage, the amplifier will shut down protecting the
speakers
from
direct
current.
Short
Circuit
Protection
The
circuit
protects the amplifier
from
damage
due
to a short found
in
the speakers or
wiring.
If
one
of
the speakers or
its
wiring
comes
in
contact
with
ground, the amplifier will
shut down.
To
resume normal operation, correct the problem
and
turn
the
head
unit off,
then
back
on.
The
amplifier will
reset
and
play
again.
Thermal
Protection
To
protect
the amplifier
circuitry
against
damage
caused
by
prolonged exposure to
high
temperatures, a thermal protection
circuit
is
activated
if
the amplifier reaches
excessively
high
operating temperature.
Once
the thermal
circuit
is activated, the
amplifier
will
shut down to
cool
off.
The
amplifier will automatically
turn
back
on
once
it
cools down to a safe operating temperature.
Tri
ModeCapable
(ELR265,
ELR2100,
Jt
ELR2150)
If
so
desired, the amplifier
may
be
run
in
stereo
and
mono
at the
same
time. For example,
this feature would allow
you
to run a pair
of
mid
and
tweeters
in
stereo
and
a sub-woofer
mono
(See
Page
13).
Built-in
Crossover
The
LLELFI"amplifiers
include a built-in variable **high
and
low
pass
crossovers.
The
crossover features a variable frequency selection (50Hz'"
250Hz)
for
precise
high
or low
pass
filtering.
**Except
ELFl1190,
1300,
1500
0<
1800
which
have
a
50
,.,
250Hz
low
pass
filter.
Bass
Boost
For
added
low frequency performance the amplifiers are
equipped
with
switchable 6 or
12dB
bass boost @
45Hz.
Line
Out
One
set
of
full range line outputs
have
been
provided
for
convenient connection to
additional amplifiers
in
the system.
