Connecting the DVD receiver
Connect the supplied FM antenna to the FM ANTENNA
socket on the unit.
If reception is poor, connect the outdoor antenna.
Note
• Before attaching a 75 ohm coaxial cable, disconnect the supplied
FM antenna.
Caution
• To avoid noise, keep antennas away from the system, the
connecting cord and the AC power cord.
Caution
• To avoid damaging the speakers with a sudden high-level
signal, be sure to switch the power off before connecting
the speakers.
Before connection
Check the impedance of your speakers. Connect speaker
with an impedance of 4
Ω ~ 16 Ω.
The black speaker terminals are “-” (negative).
Generally, the “+” side of the speaker cable is marked to
make it distinguishable from the “-” side of the cable.
Connect this marked side to the “+” terminal and the
unmarked side to the black “-” terminal.
How to connect
