THE SELF-POWERED ADVANTAGE
Having manufactured self-powered sound reinforcement loudspeakers
since 1995, Meyer Sound has pioneered and refined this technology to
produce systems that are powerful and reliable. Self-powered systems
eliminate heavy, expensive, amplifier racks and large loudspeaker
cables, thereby lowering costs. With no need to calibrate gain and
crossover settings, self-powered systems are easy to use and go from
the truck to fully rigged and back in minutes.
UPJunior incorporates a proprietary two-channel, class AB/bridged
power amplifier and sophisticated control circuitry housed within the
cabinet, dramatically simplifying setup and installation. UPJunior’s
integrated amplifier delivers 300 watts of total burst power, while
the onboard processing includes an electronic crossover, phase and
frequency response correction filters, and driver protection circuitry,
including peak and rms limiters on each channel that prevent driver
overexcursion and regulate the temperature of the voice coil. Limiter
activity is easy to monitor with high-color limit LEDs on UPJunior’s
rear panel.
The optional RMS remote monitoring system module continuously
reports the status of all key system parameters from a remote
computer running Windows OS. Other options for UPJunior include
weather protection and custom color finishes for applications requiring
specific cosmetics.
The modular, field-replaceable amplifier/processing package also
incorporates Meyer Sound’s Intelligent AC power supply, which
automatically adjusts for any line voltage worldwide and provides both
soft turn-on and transient protection.
Meyer Sound self-
powered systems
enclose their
complex crossovers,
protection circuitry,
and power amplifiers
entirely within the
enclosure, resulting
in the greatest ease
of setup and use.
