The AB International Professional Series Model
4200A is a four channel full featured Amplifier.
This compact instrument (three rack unit) is
equipped
four independent balanced and unbalanced inputs,
detented
Clip” indication, convection cooled, Stereo/
Bridge switches. The 4200A delivers 100 Watts
into 8 Ohms, 200 Watts into 4 Ohms and 300
Watts into 2 Ohms all four channels driven from
20Hz
Model 4200A incorporates a three year Five Star
protection plan featuring the following unprecedented circuitry. VI energy limiters are incorporated for short circuit protection. If an extreme
low impedance exist, a current sensing circuit will
reduce the output to prevent amplifier overdrive.

If an abnormal high AC line voltage is present or an
excessive voltage surge appears, the amplifier will
detect the situation and turn itself off. If an unlikely
DC situation occurs, DC sensing circuits will trigger
the amplifier channel and turn off. Thermal sensors
are installed in each channel to prevent an over
temperature condition.

hard clipping from improper use.
Other features included are internal selectable input
sensitivity, ground lift switch and fully modular
design for service accessibility.
