Subwoofer Connections - Indiana Line HC 505 Installation And Use Manual

SUBWOOFER CONNECTIONS

All connections have to be made before the power cord
is plugged in the socket.
If your amplifier is equipped with stereo signal outputs, link
them by using a shielded cable (RCA) to the 1 LINE IN
subwoofer inputs, keeping the "R" and "L" channels.
If your amplifier is just equipped with mono signal output
(subwoofer/LFE), link it by using a shielded cable (RCA) to
the 1 LINE IN L/mono input of the subwoofer.
If your amplifier is equipped only with powered outputs
(speakers), link them to the 8 HI LEVEL IN terminals.
It's possible to realize a 2.1 channel system by linking a pair
of speakers to the filtered 7 HI LEVEL OUT terminals.
Connect the plug to a 220-240 Volt (50 Hz) socket.
SUBWOOFER USE
Set the 4 switch to the "AUTO" position (red-coloured 3 led).
The subwoofer automatically switch-on as soon as a signal is
present (green-coloured 3 led) and turn to the stand-by
mode some minutes after the signal is not present.
If you would like turn-off the subwoofer, set the 4 switch to the
"OFF" position (red-coloured 3 led).
Setting the 4 switch to the "ON" position, the subwoofer is
always running (green-coloured 3 led).
Adjust the cut frequency of the subwoofer by the 6
CROSSOVER control: put the knob to the centre of
its excursion and turn it until you find the right
position for your system and for the listening room.
Adjust the bass frequencies level by the 2 VOLUME control,
choosing the right position for your system and for the
listening room.
The right phase relation between loudspeakers and
subwoofer depends on the boxes placement inside the room:
try to adjust the position of 5 PHASE control, then choose
the right one for your system and for the listening room.
Placing the subwoofer, please remember that the distance
from the walls plays an important role on its performances:
try to move the box to find the right position.
Place the subwoofer in a location away from heat sources,
dust and moisture. Do not cover the subwoofer. If you
experience blown the fuse, replace it with same type one;
doing otherwise, the warranty will avoid and the subwoofer
can be damaged. To prevent electrical shocks, do NOT open
the cabinet before having disconnected the power cord.
Disconnect the power cord in case of a long inactivity.
