CONNECTION DIAGRAM

Check that the power is off before you proceed with the connec-
tions. Always remember to switch the power off if you decide to
change the connections while you are using the model.
SPEAKER SYSTEM
As shown in Fig. 1, connect the R (right) channel
speaker to the M-25's R speaker output terminals,
and the L (left) channel speaker to the M-25's L
speaker output terminals. Both speakers are clearly
marked with plus and minus polarities (red and
white, respectively). The M-25's speaker output
terminals are similarly marked. Make sure that you
connect like poles (plus to plus, minus to minus).
PREAMPLIFIER
As shown in Fig. 2, use the accessory connecting
cords to connect the stereo preamplifier's output
terminals to the M-25's input terminals. The
terminal which is closer to you is for the R (right)
channel, and the connector furthest away is for the
L (left) channel.
