Introduction
Congratulations 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.
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.
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 equipment at the top.
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 responsible 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 designed 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:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
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.
