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 15˚ vertical.

The Impulse 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

our patented DDT™ compression, which virtually eliminates audible power amplifier clipping. Cooling is via natural air convection - no noisy fan!

Molded-in hand grips on either side of the front and a full handle on the right side provide ease of transport, while multiple mounting points (top, bottom and right side) for the Peavey Versamount

The combination of the signal-processed servo-controlled woofer with the ribbon tweeter provides a clarity and impact far beyond conventional powered enclosures. The Class D power amps and switch-mode power supply, along with the neodymium magnet systems on the drivers, provide this high level of technological sophistication at a very light weight and very reasonable cost.

Applications

The Peavey Impulse® 12D has a variety of applications, including sound reinforcement, public address, side fill system, karaoke and musical playback.

A typical signal source for the line-level inputs of the Peavey Impulse® 12D 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 and used as well.

CIRCUIT BREAKER (1)

The unit is AC power line protected from overloads and fault conditions with a 5 amp circuit breaker. This breaker should not trip unless there is a fault in the amplifier circuitry or an abnormal operating condition which causes excessive mains current to flow. If the breaker trips, set the Power switch (3) to OFF, wait a brief period of time for the breaker to cool, then reset the breaker.

If the circuit breaker trips, the center button will pop outward approximately 1/4”, and can be reset by pushing upward and inward. Under normal (not tripped) conditions, the center button is relatively flat.

If the unit continues to trip the breaker, or trips it immediately after being reset, do not keep resetting it. The system should be taken to a qualified Peavey Service Center for repair.

IEC POWER CORD CONNECTION (2)

This receptacle is for the IEC line cord (supplied) that provides AC power to the unit. It is very important that you ensure the proper AC line voltage is supplied to the Impulse® 12D. You can find the proper voltage for your Impulse® 12D printed next to the IEC line (power cord) on the rear panel of the unit.

Please read this guide carefully to ensure your personal safety as well as the safety of your equipment. Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not have a ground pin, a suitable grounding adapter should be used and the third wire should be grounded properly. To prevent the risk of shock or fire hazard, always be sure that the mixer and all other associated equipment are properly grounded.
