Important Safety Instructions FCC COMPLIANCE NOTICE This device complies with part 15 of the FC

14、C 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 par

15、ty responsible for compliance could void the users 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 harmf

16、ul 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 wil

17、l not occur in a particular installation. If this equipment does cause harmful interference to radio or televi- sion 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

18、 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. IMPORTANT Commercial Audio Series

19、amplifiers require Class 2 output wiring. MAGNETIC FIELD CAUTION! Do not locate sensitive high-gain equip- ment 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 d

20、evices that are located nearby. The field is strongest just above and below the unit. If an equipment rack is used, we recommend locat- ing the amplifier(s) in the bottom of the rack and the preamplifier or other sensitive equipment at the top.

If damage is found, notify the transpor- tation company immediately. Only you can ini- tiate a claim for shipping damage. Crown

38、will be happy to help as needed. Save the shipping carton as evidence of damage for the shippers inspection. We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory pack. YOU WILL NEED (not supplied):

39、 Input wiring cables Output wiring cables Rack for mounting amplifier (or a stable surface for stacking) WARNING: Before you start to set up your amplifier, make sure you read and observe the Important Safety Instruc- tions found at the beginning of this manual. 2.2 Install Your Amplifier CAUTION: B

40、efore you begin, make sure your amplifier is disconnected from the power source, with the power switch in the “off” position and all level controls turned completely down (counterclock- wise). Use a standard 19-inch (48.3 cm) equipment rack (EIA RS-310B). See Figure 2.1 for ampli- fier dimensions. Y

41、ou may also stack amps without using a cabinet. NOTE: When transporting, amplifiers should be supported at both front and back. 2.3 Ensure Proper Cooling When using an equipment rack, close any open spaces in rack with blank panels. DO NOT block front or rear air vents. The side walls of the rack sh

42、ould be a minimum of two inches (5.1 cm) away from the amplifier sides, and the back of the rack should be a minimum of four inches (10.2 cm) from the amplifier back panel.

You can also u

44、se either bal- anced or unbalanced wiring. Figure 2.3 shows balanced connector pin assignments for XLR and phone. Figure 2.4 shows unbalanced connector pin assign- ments for XLR and phone. Figure 2.5 shows barrier strip input wiring for a balanced signal. Both channels should be wired using a common

45、 center terminal for ground connection. NOTE: Custom wiring should only be performed by qualified personnel. Figure 2.3 Balanced Input Connector Wiring Figure 2.4 Unbalanced Input Connector Wiring 2 Setup 2.5 Choose Output Wire and Connectors Crown recommends using professionally constructed, high-

46、quality, two- or four-conductor, heavy gauge speaker wire and connectors. You may use terminal forks or bare wire for your out- put connectors (see Figure 2.7). CH and CL Series amplifier ter- minal strips accept up to 10 AWG terminal forks which fit over a #8 screw. To prevent the possibility of short circuits, wrap or otherwise insulate exposed loudspeaker cable and connectors. Also, a no- touch cover, which covers the terminal strips, is provided to help prevent short circuits. To remove this cover, 1. Loosen screws inside top and bottom holes of cover (see Fig
