apparatus.
11. Only use attachments/accessories specified by the manufacturer.
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 normally, 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. WARNING: THIS APPLIANCE SHALL BE CONNECTED TO A MAINS
SOCKET OUTLET WITH A PROTECTIVE EARTHING CONNECTION.
18. DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR SPLASHING AND
ENSURE THAT NO OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES,
ARE PLACED ON THE EQUIPMENT.
19. THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REMAIN
READILY OPERABLE.
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.
WARNING: PAY ATTENTION TO A PROCEDURE, PRACTICE, CONDITION
OR THE LIKE, IF NOT CORRECTLY PERFORMED OR ADHERED TO, COULD
RESULT IN PERSONAL INJURY OR DEATH.
CAUTION: PAY ATTENTION TO PROCEDURE, PRACTICE, CONDITION OR
THE LIKE, IF NOT CORRECTLY PERFORMED OR ADHERED TO, COULD
RESULT IN DAMAGE OR DESTRUCTION TO PART OR ALL OF THE
COMPONENT .
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
T-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.
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.
Declaration of Conformity
Due to line current harmonics, we recommend that you contact your supply authority before connection.

Installation Instructions
Unboxing the Amplifier
Please open the packing box and check whether the equipment has been damaged during transportation. If damage is found, please notify the transportation company
immediately. Only you can make a claim for shipping damage. Crown is happy to help as needed. Keep the shipping carton and use it as evidence of damage to the
equipment when the shipper checks it.
In addition, we recommend that you save all packaging materials for future transportation of the device. Do not transport equipment without factory packaging. You will need
the following items to install the amplifier (not provided):
• Input cable
• Output cable
• Bracket used to support the amplifier when mounted in the rack or a stable table to place the amplifier on (the amplifier should always be supported from the bottom)
WARNING: Before you start installing the amplier, make sure you have read and followed the important safety
instructions listed at the beginning of this manual.
WARNING: Before starting the installation, make sure you have disconnected the amplier from the power supply, set
the power switch of the amplier to the "off" position, and adjusted all volumes to the lowest (fully counterclockwise)
position.
Installing the Amplifier
CAUTION: Before you begin, make sure the amplifier is disconnected from the
power source.
Use a standard 19-inch (48.3 cm) equipment rack (EIA RS-310B). Please refer to the
specifications (see “Specifications") for the specific power amplifier size.
NOTE: During transportation, support must be provided on the front and back of the
amplifier.
Proper Cooling
Air flow is front to back as illustrated in Figure 2. If using equipment racks, we recommend placing
sensitive equipment at least 20 cm away from the amplifier. When using an equipment rack,be sure to
use empty panels to close all open spaces. Do not block the front and rear vents. Leave at least 5.1 cm of
space between the brackets on both sides and the amplifier, and at least 10.2 cm between the brackets on
the back and the amplifier space.

available to us free and clear of all liens or other encumbrances. The refund will be equal to the actual purchase price, not including interest, insurance, closing costs, and
other finance charges less a reasonable depreciation on the product from the date of original purchase. Warranty work can only be performed at our authorized service
centers or at the factory. Warranty work for some products can only be performed at our factory. We will remedy the defect and ship the product from the service center or our
factory within a reasonable time after receipt of the defective product at our authorized service center or our factory. All expenses in remedying the defect, including surface
shipping costs in the United States, will be borne by us. (You must bear the expense of shipping the product between any foreign country and the port of entry in the United
States including the return shipment, and all taxes, duties, and other customs fees for such foreign shipments.)
HOW TO OBTAIN WARRANTY SERVICE
You must notify us of your need for warranty service within the warranty period. All components must be shipped in a factory pack, which, if needed, may be obtained from
us free of charge. Corrective action will be taken within a reasonable time of the date of receipt of the defective product by us or our authorized service center. If the repairs
