INTRODUCTION 3IntroductionIntroductionCongratulations on your choice of theHarman Kardon HK 980 Integrated Amplifier.In order to obtain the best performance fromthis integrated amplifier, please be sure to readthis owner's manual and use your integratedamplifier only in accordance with its instructions.The special features of this unit include:HCC(High Instantaneous Current Capability)The amplifier sections react rapidly to musicaltransients, providing the instantaneous currentnecessary to precisely drive and control nearlyany loudspeaker system.Ultrawide BandwidthThe bandwidth of this unit is exceptionally wideand is independent of negative feedback. Thisimproves transient accuracy and phase linearity.Low Negative FeedbackThis unit has been designed to have low distor-tion and wide bandwidth without high negativefeedback. This further improves its dynamicaccuracy.Discrete Component CircuitryIn order to achieve the above goals, all discreteelectronic circuitry has been employed. Noavailable integrated circuits could provide thishigh level of performance.Sophisticated ElectronicProtection CircuitryHarman Kardon's unique protection circuitryguards the amplifier from short circuit ordamaged speakers and wires, without impairingsound quality by the use of current limiting oroutput relays.General instructionsAlways Use at 230V ACThis unit is designed for operation with 230V AC.Use only domestic AC outlets. Connecting theunit to an outlet supplying a higher voltage maycreate a fire hazard.Handle the Power Cord GentlyDo not disconnect the plug from the AC outletby pulling the cord; always pull the plug itself.Pulling the cord may damage it.
