5. PREPARATION AND OPERATION

Speaker placement

• Place the speakers symmetrically to the listener at least one meter away. The subwoofer emits non-directional sound, therefore it can be located in any place of the room where it so unds the best.
• Place MSS far away from monitors and TV sets, as insignificant image distortion in these supersensitive devices is possible.

Installation and operation

MS-2050/MS-2051 speaker systems can be connected to virtually any audio devices: DVD/CD players, PCs, laptops, etc. (see connection diagram in Fig. 4).
- Before making any connections, make sure the MSS is off and unplugged. Then connect speakers to the subwoofer AUDIO OUTPUT L/R @ terminals with the help of included audio cables. Observing the polarity connect the right speaker to the subwoofer AUDIO OUTPUT R with the audio cable and the left speaker - to the AUDIO OUTPUT L. Pay attention that the plus (red) cable wires of speakers must be connected to the subwoofer plus terminals (+ ++) and the minus (black) cable wires of speakers - to the subwoofer minus terminals (- - - ) (see connection diagram in Fig. 4).
Note. Check the reliable fixation of wires in the terminals, polarity of connection and absence of contact of the bared wires with each other and the metal parts of the hardware.
