Amplifier
choices
and

settings
The
following
chart
shows
Martin
Audio
power
amplifier
choices
(indicated
by
dots)
and
Martin
Audio
DX1.5
or
DX2
limiter
settings
(in
red)
to
obtain
optimal
performance
from
the
wide
range
of
O-Line
array
sizes
and
patch
configurations
possible.
Single
channels,
two
channel
and
four
channel
configurations
are
shown.
Multi
‐
channel
configurations
are
useful
where
zone
control
may
be
required.
To
avoid
amplifier
clipping
(which
dumps
excessive
power
into
the
HF
arrays
in
the
form
of
odd
‐
order
harmonics)
it
is
best
to
choose
the
highest
power
amplifier
in
the
range
indicated.
Note
that
power
amplifiers
must
be
set
to
the
industry
standard
maximum
voltage
gain
of
32dB
(x40)
with
a
correctly
limited
DX1.5
or
DX2
system
controller
to
comply
with
warranty
conditions.

ClipLim
settings
Martin
Audio
loudspeakers
are
AES
power
rated.
AES
ratings
allow
for
up
to
6dB
voltage
(4
x
power)
instantaneous
peaks.
We
therefore
recommend
that
you
set
your
DX1.5
or
DX2
output
channel
ClipLims
to
+6dB.
Controller
presets?
Note
that
we
do
not
publish
fixed
presets
for
the
O-Line
–
apart
from
recommending
a
standard
60Hz
high
pass
filter
and
the
required
limiter
settings.
The
O-Line
Software
–
used
to
optimise
the
array
shape
–
also
generates
the
controller
settings
required
for
a
flat
in
‐
situ
system
response
or
to
meet
your
chosen
house
curve
using
the
Optimise
EQ
function.
