Removal Replacement Before turning on the amplifier's power switch: · Make sure that the positive (+) and negative (­) speaker cables do not contact each other. Otherwise, a shortcircuit may occur, causing damage to the amplifier. · Be sure to connect the speaker cables with correct polarity (connect the speaker's positive (+) and negative (­) terminals with the amplifier's corresponding speaker terminals). Reversed polarity results in impaired bass-range reproduction, causing mislocalization of the sound image. Also, be sure to connect the Right and Left speakers with the amplifier's corresponding speaker terminals. · Pull lightly on the speaker cables to ensure that they are connected firmly. 2 Placement The sound quality a speaker system reproduces varies greatly depending on the construction and area of the room where it is installed, as well as the location and size of the furniture.
