such as EQ and gain are usually the cause of clipping and distortion. These
functions are easily provided by either an outboard mixing console or outboard
EQ devices.
POPS15a features an onboard digital signal processor (DSP) that performs
analog to digital conversion, equalization, high-order crossover, delay and
system dynamics processing.
POPS AND HIGH AMBIENT TEMPERATURES
POPS15a has been designed to work in a wide range of ambient temperatures.
When using POPS15a however, consideration must be given to both the ambient
temperature and the added heat produced by exposure to direct sunlight.
In a “shaded” environment, POPS15a is rated for normal operation up to 40
o
C
(104
o
F). In environments where POPS15a is subjected to direct sunlight, a
portion of that direct solar energy is absorbed by the enclosure and the external
heat sink. POPS15a’s color and resin formulations have been specifically
designed to minimize the thermal/solar gain of the enclosure and the heat sink
has been clear- anodized to minimize its solar gain as well.
It is recommended that whenever possible POPS15a should be used in either a
shaded area, or shade provided via an external “umbrella” type of sun shade.
Solar gain precautions should be taken any time the ambient (air) temperature is
90 F (32 C) or higher and if POPS15a is intended to be used in direct sunlight.
SETUP AND USE OF POPS15a
All connections to POPS15a are made on the rear amplifier panel. The input
panel is shown below:
