Description
®
The Peavey Impulse 12D is a powered, bi-amplified, two-way speaker system engineered to provide very high levels of performance
in a compact powered loudspeaker. This two-way powered system is comprised of a 1200 W peak class D power amplifier driving a 12"
Neodymium magnet based, dual voice coil Scorpion
amplifier, and is coupled to a low coloration waveguide with a coverage pattern of 100˚ horizontal by 30˚ vertical.
®
The Impulse 12D is capable of up to 131 dB peak SPL. The enclosure utilizes tough polypropylene in an injection-molded plastic modified-
trapezoidal form, with a coated perforated steel grille to offer an attractive yet durable powered speaker system. The cabinet and grille are
shaded a dark-grey (an off-white version is also available).
Two independent mixed input channels each offer a level control and a balanced input to the preamp/EQ electronics. Each channel has a
combo female XLR and 1/4" TRS phone jack. It is switchable between mic-level and line-level sensitivity. Channel one has an additional
Euro-style jack connector, while channel 2 has an additional pair of RCA jacks. A line out section has XLR, TRS ¼" phone, and Euro-style jack
connectors. These outputs allow linking of additional speaker systems feed of the signal to a powered subwoofer, or etc.
Included in the input panel is a bay for optional function modules such as a Wireless Receiver, Digital Audio Input or a 10-band EQ.
Extensive tone shaping is available via DynaQ
processing available, a woofer servo senses back-EMF that is not a result of the drive signal from the woofer voice coil and subtracts the error
so that the woofer cone follows the drive waveform more precisely. The Contour circuit is for accentuating bass and treble at low listening
volume levels.
The power amplifiers providing the bi-amplification are low-distortion, Class-D units providing 1200 W peak available power into the nominal
4 ohm load of the woofer, and a 150 W peak available power into the nominal 8 ohm load of the tweeter. The woofer amplifier uses IPR
switching technology, and the power supply for both amps is a switch mode type for low weight and high efficiency. Both amplifiers feature
