Description and Features Harman Kardon's HK 3470 is the world's first stereo receiver to offer VMAx®. VMAx is a proprietary signal-processing technique that creates an open, spacious sound field when only two loudspeakers are available. VMAx circuitry is able to decode the ambience of a concert hall or theater from a stereo recording. The HK 3470 is a full-featured Stereo receiver, with five inputs and an FM stereo/ FM/AM tuner with RDS capabilities that provide for the utmost flexibility. A high-quality phono input is available so that you may continue to enjoy your existing record collection as well as the latest CD recordings. The HK 3470's powerful amplifier uses traditional Harman Kardon High-Current Design philosophies to meet the wide dynamic range of any program selection. Harman Kardon invented the high-fidelity receiver more than forty-seven years ago. With stateof-the-art features and time-honored circuit designs, the HK 3470 is one of the finest receivers ever offered by Harman Kardon. s Harman Kardon Designed High-Current, Ultrawide Bandwidth Amplifier s VMAx Processing Mode - Exclusive to Harman Kardon Receivers s Phono Input Section s Speaker 1/Speaker 2 Outputs for High- Quality Sound in Two Locations s Pre-Out/Main-In jacks for use with External Amplifiers, Equalizers or Speaker Processors s Programmable Learning Remote Control s Subwoofer Output s Tuner with RDS Data Program Information Displays INTRODUCTION 3 Important Information Important Safety Information Verify Line Voltage Before Use Your HK 3470 has been designed for use with 220-240-volt AC current. Connection to a line voltage other than that for which it is intended can create a safety and fire hazard, and may damage the unit. If you have any questions about the voltage requirements for your specific model, or about the line voltage in your area, contact your selling dealer before plugging the unit into a wall outlet. Do Not Use Extension Cords To avoid safety hazards, use only the power cord attached to your unit. We do not recommend that extension cords be used with this product. As with all electrical devices, do not run power cords under rugs or carpets or place heavy objects on them. Damaged power cords should be replaced immediately with cords meeting factory specifications. Handle the AC Power Cord Gently When disconnecting the power cord from an AC outlet, always pull the plug, never pull the cord. If you do not intend to use the unit for any considerable length of time, disconnect the plug from the AC outlet. Do Not Open the Cabinet There are no user-serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modification to the product will void your guarantee. If water or any metal object such as a paper clip, wire or staple accidentally falls inside the unit, disconnect it from the AC power source immediately, and consult an authorized service station. Installation Location s To assure proper operation, and to avoid the potential for safety hazards, place the unit on a firm and level surface. When placing the unit on a shelf, be certain that the shelf and any mounting hardware can support the weight of the product. s Make certain that proper space is provided both above and below the unit for ventilation. If this product will be installed in a cabinet or other enclosed area, make certain that there is sufficient air movement within the cabinet. Under some circumstances a fan may be required. s Do not place the unit directly on a carpeted surface. s Avoid installation in extremely hot or cold locations, or an area that is exposed to direct sunlight or heating equipment. s Avoid moist or humid locations. s Do not obstruct the ventilation slots on the top of the unit, or place objects directly over them. Cleaning When the unit gets dirty, wipe it with a clean, soft, dry cloth. If necessary, wipe it with a soft cloth dampened with mild soapy water, then a fresh cloth with clean water. Wipe dry immediately with a dry cloth. NEVER use benzene, aerosol cleaners, thinner, alcohol or any other volatile cleaning agent. Do not use abrasive cleaners, as they may damage the finish of metal parts. Avoid spraying insecticide near the unit. Moving the Unit Before moving the unit, be certain to disconnect any interconnection cords with other components, and make certain that you disconnect the unit from the AC outlet. Unpacking The carton and shipping materials used to protect your new receiver during shipment were specially designed to cushion it from shock and vibration. We suggest that you save the carton and packing materials for use in shipping if you move, or should the unit ever need repair. To minimize the size of the carton in storage, you may wish to flatten it. This is done by carefully slitting the tape seams on the bottom and collapsing the carton down to a more twodimensional appearance. Other cardboard inserts may be stored in the same manner. Packing materials that cannot be collapsed should be saved along with the carton in a plastic bag. If you do not wish to save the packaging materials, please note that the carton and other sections of the shipping protection are recyclable. Please respect the environment and discard those materials at a local recycling center. 4 INFORMATION Front Panel Controls 27 26 25 24 23 MUTE T-MON RDS PTY CT RT TA AUTO TUNED ST MEMORY PRESET SLEEP VMAx VMAx 1 2 3 4 5 6 7 8 9! ) # @$ % ^ & * ( 20 21 22 1 Main Power Switch 2 System Power Control 3 Power Indicator 4 Headphone Jack 5 Mute 6 Speaker 1 Selector 7 Speaker 2 Selector 8 Phone Input Selector 9 T-Mon Input Selector ) Tuning Button !
