1. LOUDSPEAKER SELECTION Your Plinius 8100 Integrated Amplifier is designed for use with high fidelity loudspeakers It should not be used to operate with any other type of appliance or equipment Choice of loudspeakers is one of personal taste providing the chosen loudspeakers are suitable for use with your amplifier Be certain that your loudspeakers can handle most of the rated output power of this amplifier You may find loudspeaker specifications confusing or misleading so you should discuss this with your audio dealer prior to purchase As a general rule the use of high power 200 Watt RMS or greater loudspeakers is recommended and desirable However our experience indicates that medium to low power loudspeakers 100 to 200 Watt RMS are quite often suitable for use on this amplifier provided the volume is maintained at a level where no distortion is audible Impedance of the loudspeaker load is important to ensure the rated performance of this amplifier Any combination of loudspeakers may be used but the total average impedance load for each channel should be within a range of 4 to 8 ohms Again if you have doubts about the impedance of your loudspeaker configuration we recommend you speak to your PLINIUS dealer SPECIFICATIONS 100 WATTS RMS PER CHANNEL INTO 8 OHMS 140 WATTS RMS PER CHANNEL INTO 4 OHMS BOTH CHANNELS DRIVEN FROM 20Hz TO 20kHz AT LESS THAN 0 1 TOTAL HARMONIC DISTORTION DYNAMIC HEADROOM 1dB or greater at2.
