Important Safety Instructions FCC COMPLIANCE NOTICE This device complies with part 15 of the FCC rules. Operation is subject t

14、o 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 c

15、ould 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 harmful interference in a residentia

16、l 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 ins

17、tallation. 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 relocate the receiving antenna

18、. 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 K Series amplifiers require Class 2 output wiring. MAGN

19、ETIC 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 devices that are located nearby. The field is s

20、trongest 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.

It is designed to provide

34、 very high power in a lightweight package, without using a cooling fan. This means your amp runs quieter (no fan noise) and cleaner (no need for filters). The K Series amplifiers are very energy- efficient as well. Modern power amplifiers are sophisticated pieces of engineering capable of producing

35、extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed. In addition, the K Series amplifiers include a number of features which require some expla- nation before they can be used to

36、 their maxi- mum advantage. Please take the time to study this manual so that you can obtain the best possible service from your amplifier. 1.1 Features Accurate, uncolored sound with very low distortion. High damping factor for tight, clean bass response. Advanced design for energy conservation. Ve

37、rsatile, handling a wide range of speaker impedances and outputs. Switchable input sensitivity. “Soft Start” feature prevents the amplifier from drawing large currents when it is first turned on. Can be mounted in standard 19-inch (48.3-cm) rack. Uniquely molded, cast- aluminum front panel provides

38、exceptional air circulation. Exclusive BCA (Balanced Current Amplifier) power design provides high efficiency for quiet, fan-free operation. Advanced protection circuitry guards against shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads and internal f

39、aults. Mono mode switches allow you to set up your amps/speakers in the configuration that best suits your needs, with combined amp inputs, combined amp outputs, or both. Patented front-panel design. Backed by the industrys ONLY three-year, no-fault, fully transferable warranty. 2 How to Use This Ma
