ENGLISH NAMES AND FUNCTIONS BASIC CONNECTIONS BASIC OPERATIONS ADVANCED CONNECTIONS ADVANCED OPERATIONS TROUBLESHOOTING FEATURES The PM-KI-PEARL is a successor model for the PM-15S2, retuned using higher-grade parts developed for the PM-KIPEARL model. ¶ HDAM-SA3 Module The HDAM-SA3 is a key amplifier module for a current feedback amplifier and is mounted on the voltage-current conversion block, which is the most important part of an amplifier, for further improved circuit stability and high-speed processing. ¶ Constant Current Feedback Phono Equalizer The phono equalizer adopts a system that maintains the current feedback at a constant level within the audible range, and supports both the MC and MM cartridges. Thanks to this system, extremely smooth sound over the entire band of frequencies with less noise can be achieved. ¶ Linear Control Volume This volume control amplifier is a combination of the MAS6116 from MAS and the inverse NF-type current feedback amplifier. The amplifier section adopts a fully discrete design, combining the HDAM-SA3 and the HDAM-SA2. ¶ CD Direct Input Buffer Amplifier An input buffer amplifier that uses the HDAM-SA2 is mounted directly after the input jacks in order to directly convey highquality Super Audio CD sound. ¶ V/I Servo Current Feedback Power Amplifier To further improve the stability of the power amplifier, the V/I Servo system has been developed. With this system, fluctuations in the output offset voltage are converted into currents and compensated in Current mode. Thus, the audio quality and stability can be enhanced with this newly developed V/I Servo system. ¶ F.C.B.S. A Floating Control Bus System enables the user to connect up to four PM-KI-PEARL units for linked operation. A diversity of applications, such as complete bi-amp with two units and 5.1 multichannel connections with three units, become available. ¶ Power Amplifier Direct Input With this function, this unit serves as a power amplifier. As this function can be turned ON or OFF with a button on the front panel, this unit can be used as part of various audiovisual systems. ¶ Double-Layered Chassis ¶ Copper Plated Chassis ¶ Large Capacity Dual Shield Toroidal Transformer ¶ Large Capacity Block Condenser ¶ 5mm Aluminum Top Cover ¶ Star Cap Condenser 2 BEFORE USE EQUIPMENT MAINS WORKING SETTING Your Marantz product has been prepared to comply with the household power and safety requirements that exist in your area. - Power requirements (U.S.A AC 120V 60Hz - Power requirements (Europe AC 230V 50/60Hz INAPPROPRIATE PLACES FOR INSTALLATION To keep your amplifier in perfect working order for the longest possible time, avoid installing the unit in the following locations. • Wherever it will be exposed to direct sunlight • Wherever it will be close to a heater or other heat-radiating appliance • Wherever the humidity is high or ventilation is poor • Wherever it is very dusty • Wherever it will be subject to vibration • On top of a rickety stand or in an unstable location which is tilted at an angle • Near windows where there is a chance of exposure to rain, etc. • On top of an amplifier or other component which dissipates a great deal of heat To ensure proper heat dissipation, install the unit while leaving clearances between the unit and wall or other components, as shown in the figure below. Left 0.2 m (7-7/8 in) or more Above 0.2 m (7-7/8 in) or more Right 0.2 m (7-7/8 in) or more Rear 0.2 m (7-7/8 in) or more 7 Do not place objects on top • Refrain from placing any objects on top of the unit. Do not touch hot areas, especially around the "hot surface mark" during Hot surface mark and immediately after use. During and immediately after use, this product is hot in areas other than the controls and rear panel connection jacks. Do not touch hot areas, especially around the "hot surface mark" and the top panel. Contact with hot areas can cause burns. OTHERS
