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). It can also be used with the Peavey ® Wall-Mount Speaker Stand (00922940 black, 00487390
white), which will fit into the built-in stand mount cup on the bottom of the cabinet.
CONNECTING AC POWER TO THE IMPULSE
®
12D
The Impulse ® 12D comes with a 6-foot IEC connection AC power cord. If you are using an extension cord or
power strip with this powered speaker, make sure it is of good quality and of a sufficient current capacity to
maintain safety and maximize the power output capability of the Impulse
® 12D. For maximum undistorted
output, do not connect any other device to the same extension cord that the Impulse ® 12D is connected to. Do
not exceed the rated current capacity of the extension cord with the sum total of all units connected to it.
When first plugging in the AC cord, make sure the power switch is in the Off position, and then turn it On only
once the power cord has been connected. Built-in muting will engage when the proper sequence of steps is
taken.
SPECIAL NOTE FOR PERMANENT INSTALLATION
When installing the Impulse ® 12D, AC power runs will
be used and a certified electrician should be consulted to be sure that all AC wiring complies with local codes
and regulations. It is also advisable to use a cable clip properly affixed to the cabinet to relieve strain on the IEC
power cord connected to the amplifier module at (2) so the power cord cannot be pulled out or vibrate loose.
USE OF THE IMPULSE
®
12D WITH A SUBWOOFER POLE TUNNEL
The built-in stand mount cup allows use with the Peavey SP ® 118 Sub and the accessory pole that it is designed
to use, Peavey part #00326530.
The pole used is 51-3/4” long and has a nominal diameter of 1-3/8”.
Always be sure to place the subwoofer used in this manner on a flat, level and stable surface.
USE OF THE IMPULSE
®
12D WITH A SPEAKER STAND
The Impulse ® 12D has a stand mount cup molded-in so that the system can be stand mounted on a standard 1
3/8” (36mm) diameter stand pole.
WHEN USING STANDS OR POLES, BE SURE TO FOLLOW THESE PRECAUTIONS:
Check the stand or pole specs to make sure that it can support the weight of the Impulse
®
12D (39 lbs./17.7kg),
and observe all safety precautions stated by the stand manufacturer, including the maximum height for which the
stand is rated.
Always place the stand on a flat, level and stable surface, and be sure to fully extend the stand legs as per the
stand manufacturer’s instructions.
Orient the stand legs for the least danger of tripping to those in the vicinity of the stand. Never block a doorway or
hallway with the legs of a stand.
Route cables so that people will not trip over them or tip the speaker over. Use of duct tape, cable channels or
guards, or other appropriate tie-down/cover-up devices should be carefully considered and implemented.
When installing or un-installing the speaker on the stand, it is a good practice to have a helper if possible, as it can
be hard to “thread the needle” and mate the stand cup to the stand pole while holding the Impulse
®
12D speaker
system at arm’s length. It is also helpful if someone holds the speaker stand and pole down while the Impulse
®
12D is removed from the stand pole; this prevents the Impulse
®
12D from pulling the pole up with it.
When using stands outdoors, never attach banners or flags to the stands or the Impulse
®
12D speaker system, as
strong winds may cause the speaker to blow over. If there is a possibility of windy conditions, it may be prudent to
consider weighting or locking down the stand legs to prevent the Impulse
®
12D speaker system from being blown over.
