An MA 4 can be set to automatically switch to another of its own channels or switch
to a channel of another MA 4.

n terms of power
density, reliability and
features, there’s never
been a 1U power ampli-
fi er like the new MA 4.
From its internal
limiter and redundancy
channel switching to
Power-Factor-Corrected
universal power supply,
the MA 4 is designed for
a lifetime of predictable,
reliable operation.

reduces rack cooling
demands.

#
Accurate info.
Load sensing monitors
average load impedance; display shows
open, normal or low
load. Headroom meter
is accurate regardless of
load impedance.
&
No power
sequencing
required with up
to 8 MA 4s on a
single 15-amp AC
breaker.
*
Clickless
power-up and
power-down.
$
Same AC draw and
heat at 4 or 8Ω; % No
loss of intelligibility due
to voltage or current clipping;
^
Amp channels
never overheat…
all thanks to the internal
limiter’s ability to adjust
for constant power.
BM
Remote fault

control system.
BN
Loudspeaker
protection from
excessive low
frequency
excursion and…
BO No low fre-
quency saturation

BQ
Clickless mute and
unmute from switch.
BR
Input cannot be clipped
regardless of sensitivity
setting! There’s an automatic
limiter behind the +4 dBu to
+22 dBu sensitivity controls.
BU
Less current draw from
AC line. Run thirty-two
MA 4 channels per AC line
breaker: less copper, less
conduit, fewer breakers.
CL
Very low AC line distor-
tion thanks to Power-FactorCorrection.
CM
Works anywhere; toler-
ates brown-outs. Universal
power supply runs on 85 to
260 VAC, 50 or 60 Hz.
BT
Peace of mind. Doubly
redundantly redundant automatic switching to back-up amp
channel with no external relays
required.
NEW!
Dense but well-behaved.
4 x 100 watts in 1U! Twenty-one reasons that
our new MA 4 is the most reliable, high-density
power amplifi er ever.
