The heavy-duty 12" woofer has a 2-3/8" voice coil diameter, and a 50 oz. magnet for 200 watts continuous worth
of chest-pounding bass. The RX14 compression driver tweeter is coupled to a Quadratic Throat constant direc-
tivity waveguide, covered under US patent #6,059,069, with smooth, even response, low distortion and good
high frequency dispersion.
This horn has an asymmetrical vertical polar response, aiming the main energy lobe down 10 degrees, so it is
directed at the audience instead of over their heads. The vertical polar pattern is +15 degrees, -35 degrees. This
helps reduce ceiling reflections for greater clarity and gain before feedback.
Advanced Digital Signal Processing (A.D.S.P.) provides the crossover function, driver limiting, as well as the
driver EQ to enable the speaker system to provide an accurate and neutral sound for any type of music. The DSP
processing uses 64 bit double-precision to ensure accurate and transparent sound processing, and the input/
output sections use a 48 kHz sampling rate at 24 bits for maximum fidelity. Low-jitter clocking and professional
grade components insure the sound quality is superb.
An extremely flexible system of EQ presets and adjustments is implemented in the speaker system's DSP comput-
ing core, and accessible via the rotary push-to-select knob and the LCD display.
The PVXp™ 12 DSP speaker system power amplifiers providing the bi-amplification are low-distortion ultra-reli-
able fan-cooled units providing a total of 830 peak available dynamic power for the system.
There is 630W peak available dynamic power for the woofer, and 200W peak available dynamic power for the
tweeter. The power supply for both amps is a switch-mode type, that provides reliability coupled with low cost.
Both amplifiers feature sophisticated signal compression, which virtually eliminates audible power amplifier clip-
ping. Cooling is provided via a low-noise fan, for reliable operation under any conditions.
Input is via a combo female XLR and 1/4" TRS phone jack with balanced input to the DSP preamp/EQ electron-
ics, and a Level control. A Mic/Line switch allows for use of a microphone via the extra gain available when in
the "Mic" position.
The included thru output consists of a male XLR jack and paralleled 1/4" jack. This output allows linking of
additional speaker systems, or feed the signal to a powered subwoofer, etc.
Applications
The Peavey PVXp™ 12 DSP has a variety of applications such as sound reinforcement, public address, side fill
system, karaoke or musical playback.
A typical signal source for the line-level inputs of the Peavey PVXp™ 12 DSP would be a sound reinforcement
mixing console (mixer) or the output from a CD player, MP3 player or tape deck. A dynamic microphone can
be connected directly via the XLR input and used when the Mic/Line switch in placed into the "Mic" position as
well.
