they exit from the apparatus.
11. Only use attachments/accessories specified by the manufac turer.
12. Use only with a cart, stand, tripod, bracket, or table specified
by the manufacturer, or sold with the apparatus. When a cart is
used, use caution when moving the cart/apparatus combination
to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused
for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way,
such as power-supply cord or plug is damaged, liquid has been
spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate nor mally,
or has been dropped.
15. Use the mains plug to disconnect the apparatus from the mains.
16. WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR
MOISTURE.
17. DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR
SPASHING AND ENSURE THAT NO OBJECTS FILLED WITH

18. THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL
REMAIN READILY OPERABLE.
Important Safety Instructions
MAGNETIC FIELD
CAUTION! Do not locate sensitive high-gain equipment such as
preamplifiers or tape decks directly above or below the unit. Because
this amplifier has a high power density, it has a strong magnetic field
which can induce hum into unshielded devices that are located nearby.
The field is strongest just above and below the unit.
If an equipment rack is used, we recommend locating the amplifier(s)
in the bottom of the rack and the preamplifier or other sensitive equip-
ment at the top.
WATCH FOR THESE SYMBOLS:
The lightning bolt triangle is used
to alert the user to the risk of electric shock.
The exclamation point triangle is used to alert the user to important
operating or maintenance instructions.
IMPORTANT
LPS Series amplifiers require Class 2 output wiring.
TO PREVENT ELECTRIC SHOCK DO NOT REMOVE TOP OR BOTTOM
COVERS. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING
TO QUALIFIED SERVICE PERSONNEL.
TO COMPLETELY DISCONNECT THIS EQUIPMENT FROM THE AC
MAINS, DISCONNECT THE POWER SUPPLY CORD PLUG FROM THE
AC RECEPTACLE. THE MAINS PLUG OF THE POWER SUPPLY CORD
SHALL REMAIN READILY OPERABLE.
Introduction
C
ongratulations on your purchase of a Crown
®
LPS power amplifier. All
three models in the series are powerful, rugged and reliable. They are
suited for applications such as churches, concert tours, stages, disco, pubs,
or any place that requires amplifier installation.
Features include XLR inputs, Speakon
®
and binding post outputs, stereo/
parallel/bridge-mono mode, power/fault/signal/clip indicators, forced-air
cooling; and protection against shorts, no-load, on/off muting and radio-
frequency interference.
Installation
Designed to fit into a standard 19-inch equipment rack, the unit takes up
only two rack spaces. Secure this unit with four rack-mount screws and cup
washers. For optimum cooling, rack amps without spaces between them. If
amps are racked with spaces between them, solid non-vented rack panels are
recommended between amps. Provide standard rack-mount clearance of 2
inches on each side and 5 cm in the rear.
This unit comes with a variable speed fan that auto-adjusts fan speed
depending on the temperature of the unit during operation. Airflow is front to
back, so do not place any object that may prevent heat from exiting the unit
from its back vent.
Provide standard rack-mount clearance of 2 inches on each side and
5 cm in the rear.
FCC COMPLIANCE NOTICE
This device complies with part 15 of the FCC rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may
cause undesired operation.
CAUTION: Changes or modifications not expressly approved by the party respon-
sible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules. These limits are de-
signed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
