Congratulations on purchasing the Samson dB300a active loudspeaker! The dB300a speaker system by
Samson takes the concept of powered PA systems to a new level. By combining 300 watts of super clean
power, advanced active processing and the highest quality speaker and cabinet components, the dB300a
provides studio quality sound for any kind of live sound reinforcement application. The loudspeaker features
a super heavy-duty, custom designed, 12-inch low frequency driver and a 1.75 inch titanium diaphragm high
frequency driver on a 1" throat, wide dispersion horn. The dB300a offers crystal-clear audio and an ultra-wide
sound field. The top end is clear, sweet and articulate. The low-end is enormous. The dB300a is powered by a
Class H amplifier that pumps 250 Watts to the low frequency driver and a Class AB amp that provides 50 Watts
to the high frequency section—more than enough power to fill any large club. The efficient Class H amplifier
design provides the power to deliver transient spikes with incredible punch and sonic purity. The dB300a goes
beyond concert-quality to studio-quality thanks to Samson’s exclusive Optimax processing. Optimax process-
ing uses sophisticated circuitry to compress and limit output at ideal levels. This allows the dB300a to provide
huge volume levels without sacrificing low end. The dB300a offers a practical back-panel, mixer-like preamp
section that provides mic and line inputs with individual input level controls. Controls for the selectable low
pass filter and extension output selection are also included. The trapezoidal shape of the speaker cabinet
offers more than just superior acoustics, not only is it a front-firing PA speaker, the dB300a’s are also designed
to operate as wedge-style monitors. Adding to the dB300a’s practical design is a catalog of mounting options.
With the dB300a, setup and break down is quick and easy. The compact cabinet can be easily stacked, using
the built-in stacking bumpers or stand mounted using the integral 1 3/8" pole mount receptacle. For per-
manent installations, the enclosures can be fixed to a wall or ceiling using the optional MB300U U-bracket
mounting kit. The dB300a can also be suspended using the four built-in fly points and fixed in arrays using
the MB300A array kit. If you are traveling to different venues with your loudspeaker system, the heavy-grade
steel grill, scuff-resistant textured finish and rigid corners offer excellent protection against wear and tear on
the road. As fixed sound reinforcement or as a durable, great-sounding road PA, the dB300a active monitor
is ideal for sound professionals and performers looking for serious power and studio monitor sound quality
from a PA speaker system.
