The AB International Professional Serie51590B is
a two channel stereo amplifier. This compact
(two rack unit) instrument features individual
channel level controls and 11 LED display,1/4"
jack inputs (unbalanced), XLR inputs (balanced),
ground lift switch, and a Stereo/Bridge switch.
The159OB delivers 500 Watts per channel into 8
Ohm, 800 Watts per channel into 4 Ohm, and
1050 Watts into 2 Ohm from 20Hz-20KHz at .1 %
distortion.

The159OB employs only 20dB of negitive feed-
back to reduce forward transfer distortion compo-
nents to minimum levels. VI energy limiters are
incorporated for short- circuit protection and a
thermal sensor prevents an over-temperature
condition.

Other features includes three dual speed temperature

actuated DC fans, " Soft Clip" speaker protection
circuitry, selectable input sensitivity, and a fully
modular construction for service accessibility.

The AB International Model 15908 features the
"Logic Operated Gated Output" supply system.

High current , fully complimentary output stages are

powered by dual tri-level supplies that gate the
operating voltages around the output wave form.
This is used to control and eliminate unused and
inefficient headroom.

The159OB operates from 100-240V 50-60Hz AC

mains and measures3 1/2 " high (two rack unit), 19"

wide and 15 " deep.
