Impulse 12D ® ENGLISH Thank you for purchasing the class D powered Peavey® Impulse® 12D. The Impulse® 12D features a bi-amped power section that provides 1200 watts of peak power for the woofer and 150 watts of peak power for the ribbon driver tweeter, both with Peavey-exclusive DDT™ compression. Featuring a 12” Neo dual voice coil Scorpion® woofer and the RD™2.
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™ 70 Plus mounting bracket allow maximum utility.

The ON position is with the left side of the switch pushed in nearly flush with the rear panel. REAR PANEL TOP ACCESS PANEL FOR OPTIONAL EXPANSION MODULE This panel is to be removed ONLY when installing one of a variety of Optional Expansion Modules that will be available soon for the Impulse® 12D.
INPUT 2 (B) Input 2 is switchable between line-level gain and mic-level gain. The line-level input is medium impedance balanced. The input 2 jack (8) is a combo female XLR and 1/4” TRS connector. Input 2 also has a pair of RCA phono jacks (10) wired in parallel with the above listed inputs. These are mixed in parallel with each other and are Mono inputs (not stereo inputs). The signal to input 2 is mixed with the signal from input 1 and fed to the internal crossover and signal processing.
THIS SWITCH IS OVERRIDDEN IF THE CONTOUR/BYPASS SWITCH (20) IS IN THE BYPASS MODE. THE ASSOCIATED LED (21) WILL REFLECT THIS CONDITION. The Contour/Bypass switch (20) provides a flat response in the "Bypass" or “in” position. The "Contour" or “out” position allows the positions of the other two DynaQ™ switches to affect the tone. This switch overrides the other two switches in the DynaQ section, as the other two switches have no effect when in Bypass mode.
operating instructions Cautions The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to qualified service personnel. The heat sink on the back plate can become hot to the touch. Do not block or cover the heat sink from ventilation. There must be a minimum of 4” of space behind the heat sink. Do not allow the airflow to be become blocked by objects such as curtains or drapes, thermal building insulation, etc.
The middle screw of a smaller size in the middle of each mounting plate is a retention screw. It should not be removed from the insert mounting plate, and that location should not be used as a flying point. There is no 1/4” X 20 insert at this location. The Impulse® 12D mounting inserts are designed to be used with the Peavey® Versamount™ 70 Plus mounting bracket (00454470 black, 00454460 white), as well as the Impulse® 12” array bracket (00386920 black, 00386940 white).
Connecting a Signal to the Impulse® 12D There are a variety of ways to input a signal to the Impulse® 12D. The two inputs (7,8) provide either a balanced mic- or line-level input, allowing the use of a 1/4” TRS (ring-tip-sleeve) type phone plug OR a male XLR plug, as well as a 3-conductor Euro-style jack connector (9) on input 1. Unbalanced inputs are also provided, as the ¼” input (7,8) can take a standard single-ended (tip-sleeve) phone plug. Alternatively, the RCA phono jacks (10) of input 2 can be used.
The unit is normally shipped with the button in the line-level or “in” position. However, before each use it is a good idea to check for the proper position of the switch, as it could be toggled inadvertently during transport or set-up. Due to the 30 dB of extra gain that this switch provides, DO NOT leave it in the “out” position for line-level input signal use! This could result in input-stage clipping of the Impulse® 12D and cause unnecessary distortion.
the Impulse® 12D. If an extension cord is being used to provide the AC power to the unit, ensure that it is of sufficient current capacity and that it is not also being used to supply power to any other device. The Impulse® 12D has built-in EQ to extend and smooth the natural response of the speakers in the system. Bass boost and HF EQ give the system a nominally flat response, so it should require little, if any, additional EQ.
Architectural and Engineering Specifications The powered loudspeaker system shall have a frequency response from 60 Hz to 20 kHz. The peak SPL with inaudible distortion shall reach 131 dB with music as a source, when measured at a distance of 1M and driven to full output capacity. The system shall utilize a Peavey® 12” Neodymium Dual Voice Coil Scorpion® woofer and a Peavey RD™2.6 true ribbon driver tweeter. The nominal radiation pattern shall be 100˚ in the horizontal plane, and 15˚ in the vertical plane.
