1.0 Safety Precautions
The LRAD 1950XL is capable of producing sound pressure levels that have the potential to cause
temporary or permanent hearing damage if not used properly. Always follow the safety
precautions described in this manual as well as on the unit’s operator interfaces.
The following conventions apply in this manual. Please note the warnings and take adequate
measures to ensure safe operation of the unit.
WARNING –Risk of injury or death.
CAUTION –Risk of equipment damage.
Before operating the LRAD 1950XL, do the following:
1. Read these instructions.
2. Keep these instructions in a place known to and accessible by the potential operators of the
LRAD 1950XL.
3. Heed all warnings contained in this document.
4. Follow all instructions detailed in this document.
5. Install in accordance with the instructions contained in this document.
6. Do not install near any heat sources such as radiators, heat registers, stoves, or other
apparatus that produce heat.
7. Do not connect or disconnect any cables to the unit while the primary circuit is live unless
the area is known to be non-hazardous.
8. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug
has two blades with one wider than the other. A grounding type plug has two blades and a
third grounding prong.
9. The wide blade or the third prong of the power cord is provided for your safety. If the
provided plug does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet.
10. Protect the power cord from being treaded upon, excessively bent, creased, or pinched
particularly at the point where the cable assemblies connect to the apparatus.
11. Only use attachments/accessories specified by the
manufacturer.
12. Unplug this apparatus during lightning storms or when
unused for long periods of time.
13. Refer all servicing to qualified service personnel. Servicing is
required when the LRAD 1950XL has been noticeably or
substantially damaged in any way, including cord or plug
damage, seriously dented or breached housings, or if liquid
has penetrated the interior of the device, or any
accessories.
14. The LRAD 1950XL power cord shall be connected to a main
socket outlet with a protective ground connection.
15. Follow the Operation Zones graphic on the back of the LRAD
for guidance on exposure to high acoustic levels.

2.0 Introduction
The LRAD 1950XL Long Range Acoustic Device is a powerful acoustic hailer that can be used to
project loud, clearly intelligible messages to targets at distances up to 5 Kilometers (3.1 miles).
The acoustic output from the LRAD projects from the Acoustic Array in a focused 30 degree
“cone” of sound. Sound levels outside of this cone are greatly reduced as a result of the
focused nature of the LRAD’s sound projection.
The LRAD includes a ruggedized MP3 player unit that can be used to store digital audio of any
type, as well as a handheld microphone for reproducing live spoken messages. The LRAD’s MP3
player features a built in “Alert Tone” button that instantly broadcasts a loud, piercing alert
sound that can be used to gain the target’s attention.
The LRAD 1950XL has the ability to produce a maximum continuous sound pressure level (SPL)
of 155dB at one meter from the front of the device. With this high output, clear audible
messages can be broadcast to targets at ranges of 1600 to 5000 meters, depending on weather
conditions. This high acoustic output is achieved with a peak power consumption of 1120
Watts.
The LRAD operates using AC input power from a 90 to 260 VAC power source at 50 or 60Hz.
The LRAD must be plugged into a grounded electrical outlet.
The LRAD is constructed of materials that are designed to survive in a marine environment with
proper care and maintenance. A carbon-fiber speaker housing is fitted with 316 stainless steel
hardware and other parts that are either powdercoated or hard anodized. The remote portable
amplifier pack and remote MP3 control unit are environmentally sealed and can be used in all
weather conditions. For further information on environmental specifications for this product,
see the Specifications section of this manual.
