Congratulations on purchasing the Samson dB500a! The dB500a speaker system by Samson takes the concept
of powered PA systems to a new level. By combining 500 watts of power, advanced active processing and the
highest quality speaker and cabinet components, the dB500a provides studio quality sound for any kind of live
application. The monitor features a super heavy-duty, custom designed 15-inch low frequency driver and a 1.75
inch titanium diaphragm high frequency driver on a 1" throat, wide dispersion horn. The dB500a offers crystal-
clear audio and an ultra-wide sound field. The top end is clean, smooth and vivid. The low-end is enormous. The
dB500a is powered by a Class G amplifier that pumps 400 Watts to the low frequency driver and a Class AB amp
that provides 100 Watts to the high frequency section—more than enough power to fill any large club. The effi-
cient Class G amplifier design provides the power to deliver transient spikes with incredible punch and sonic puri-
ty. The dB500a goes beyond concert-quality to studio-quality thanks to Samson’s exclusive Optimax processing.
Optimax processing uses sophisticated circuitry to compress and limit output at ideal levels. This allows the
dB500a to provide huge volume levels without sacrificing low end. The dB500a 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 Optimax dynamics 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 dB500a’s are also designed to
operate as wedge-style monitors. The cabinet’s right and left side panels are joined at different angles, so
depending on the side you choose, you get a different dispersion angle, allowing for greater flexibility on stage.
Adding to the dB500a’s practical design is a catalog of mounting options. The compact cabinet can be easily
stacked, permanently installed, mounted using the integral 1 3/8" pole mount receptacle or suspended using the
ten built-in fly points. With the dB500a, setup and break down is quick and easy. Heavy-grade steel grill, scuff-
resistant textured finish and rigid corners offer excellent protection against wear and tear. As fixed sound rein-
forcement or as a durable, great-sounding road PA, the dB500a active monitor is ideal for sound professionals
and performers looking for serious power and studio monitor sound quality from a PA speaker system.
