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 sounds the best.
• Place MSS as far away as possible from monitors and TV sets, to avoid insignificant image dis-
tortion .
Installation and operation
MS-304/MS-307 speaker system 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. The n conn ect sp eakers
to the subwoofer AUDIO OUTPUT L/R l jacks using built-in audio cables. Connect the right speaker to
the subwoofer AUDIO OUTPUT R and the left speaker – to the AUDIO OUTPUT L (see con- nection
diagram in Fig. 4).
Note. Check the fixation connectors.
• To connect the MSS to a PC, МР3/CD player, use 2RCA to mini-jack signal cable (included). Con-
nect the RCA jacks of the signal cable to the L and R jacks of the AUDIO INPUT k, and the mini-jack
(Ø 3.5 mm) of the signal cable – to the LINE OUT port of your PC sound card or to the audio output
(OUTPUT) of your МР3/CD player, as shown in Fig. 4.
• To connect the MSS to a TV set or DVD/CD player, use 2RCA to 2RCA signal cable (not included).
First connect the RCA jacks of the signal cable to the L and R jacks of AUDIO INPUT k and then
connect RCA jacks to your TV set or DVD/CD player audio output jacks, as shown in Fig. 4.
