Harman Kardon CITATION 15 Owners Manual - Page 5

INSTALLATION The Citation Fifteen produces very little heat and may be installed without regard to normal ventilation requirements. However, if you are installing the unit in custom cabinetry, it is recommended that you avoid placing the tuner directly over heat producing units such as a basic amplifier or tube-type preamplifier. (A handsome walnut enclosure or custom cabinet is available from your dealer as optional equipment.) POWER REQUIREMENTS The AC line cord plug may be inserted into any outlet furnishing 117 volts, 50/60 Hz AC current. (Voltage may vary between 105 and 125 volts.) For use in areas which provide 210 to 250 volts AC, 50/00 Hz current, the Citation Fifteen may be rewired as shown on the schematic diagram in the Technical Manual. However, rewiring should be done only by an authorized technician. Unless otherwise indicated, all Cila lion Fifteen tuners have been factory wired to operate at a nominal voltage of 117 volts AC. AC CONVENIENCE RECEPTACLE An AC convenience receptacle is provided on the rear panel of your Citation Fifteen. Any equipment connected to this receptacle will he controlled by the on/off switch of the tuner. It is therefore recommended that this receptacle be used for tuner associated accessories such as an antenna rotator, antenna booster, quad decoder, etc. FUSE The Citation Fifteen is protected by a STANDARD FAST BLOW fuse located on the rear panel. If this fuse is blown, it is to be replaced only with one of the SAME TYPE and SAME RATING. It is important to note that replacing the FAST BLOW FUSE with a slow blow type or with a fuse of higher rating, WILL PREVENT MAXIMUM PROTECTION of the tuner and could result in severe damage. Such damage will not be covered by the Factory Warranty. VOLTAGE (50/60 Hzl 105-125 VAC 210-250 VAC FUSE TYPE 3AG or AGC 3AG or AGC FUSE RATING 1.5 Amperes 1.0 Amperes ANTENNA In selecting an antenna system for use with your Citation Fifteen please keep in mind that your tuner's full potential and performance capability can only be achieved when you provide the best possible signal to the antenna terminals. If you live in a metropolitan area (or if you wish to receive signals from many directions) an ordinary crossed .dipole, conical or three element. in-line antenna should serve adequately. The three or four element in-line (uni-directional) type is the most satisfactory of the group, but due to its high directivity, it becomes necessary to include an antenna rotator to change the direction of the antenna for best reception. For near-fringe and fringe reception, a six-to-eight-element logperiodic or Yagi is recommended. Both types are excellent and offer superior front-to-back ratio, (ratio of forward pickup Lo that at the rear, greater gain and rejection of noise. Both types are highly directional and require a rotator. Far fringe reception requires an antenna with eight or ten elements. This type antenna is usually quite heavy and requires extra support and bracing when installed. Remember, FM stereo reception requires greater gain than standard monophonic FM. It is therefore, advisable to purchase the antenna which can "pull in" a station with the greatest gain and lowest possible noise. Are there high-rise buildings in your area? Water towers? Gas tanks? Mountains? They can all cause serious reception problems by reflecting FM signals which, when received, will result in audible distortion. This form of distortion is known as multipath interference and is similar to "ghosts" on your TV set. Multipath interference can be reduced or eliminated by purchasing a highly directional antenna with a rotator. Proper orientation of the antenna may tune out multipath completely, or alternate it below audibility. If installed properly, an outside antenna will reject unwanted signals, local noise, multipath interference, and provide greater signal strength than any elementary type. Increased signal strength usually results in the reception of additional stations with amazing clarity. 4
