[. . . ] B SPEAKER SYSTEM USC-M30/USC-M50 OPERATING INSTRUCTIONS Read this manual carefully to ensure that you take full advantage of all this unit has to offer. Keep the manual for future reference should any doubts or problems arise. [. . . ] Consult the amplifier's instructions. Clipping or other problems may occur in the output waveform when using the speaker systems with a high output and the amplifier's tone controls set to the maximum. Avoid using them under these conditions. Never play such special signals as a tape recorder's fastforwarding signals or sine waves continuously. When moving the speaker systems, be careful not to apply excess force to the speaker nets. Doing so could damage the speaker units. INSTALLATION The tone character produced by speaker systems depends on such factors as the size and type of room, the method of installation, etc. Pay attention to the following points when installing the speaker systems. If the bass sound is overemphasized when the speaker systems are installed directly on the floor, set them on concrete blocks or other hard stands. Note that howling may be produced if the speaker systems are placed on the same stand or shelf as a record player. If there are walls or glass doors behind or in front of the speaker systems, use heavy curtains, etc. , to prevent resonance and reflection. [. . . ] Inverting the polarities will result in unnatural sound, with the phase off or no low bass sound. Also check that all two terminal knobs are tightly fastened. Connections (The red terminals on the right side are the "<" terminals, the black ones on the left side the ">" terminals. ) Loosen the terminal knobs, insert the cables' core wires, then tighten the knobs.
