GME GR100 - Manual (Page 13)

Page 13 GR100 Instruction Manual
the GR100 is supplied with two speaker adapter leads which are designed to accept
the standard bullet connectors found on some GMe marine speakers and most marine
and automotive speaker cables . the plugs on the speaker adapters plug into the
matching the sockets on the rear of the GR100 . the plugs are fitted with protective
flexible covers .
When connecting the speakers, observe the correct polarity as shown in the diagram .
Incorrect polarity will result in a reduction of bass response and stereo effect . the use
of speakers with an impedance of less than 4 ohms is not recommended as they will
cause excessive loading of the GR100’s output circuit .
the GR100 is a two speaker system that requires one pair of wires for each speaker .
avoid shorting the speaker wires together or touching them to the supply voltage or
to ground .
Once the GR100 is connected, you can adjust the balance between the left and right
speaker using the Balance function .
antenna Connection
the antenna should be mounted in a position as high as practical to ensure good
reception especially in areas of low signal strength . When installing the antenna,
ensure a minimum clearance of around 20 cm from bow or stern rails or windscreen
frames etc . It is also recommended the antenna be placed at least one metre from
two-way radio antennas to minimise interference from radio transmissions .
to connect the antenna to your GR100, simply plug the antenna lead into the flying
antenna socket on the rear of the unit .
waterproofing the connections
after installation, the power, speaker and antenna connectors should be wrapped in
waterproof tape or similar to minimise the risk of corrosion or water damage . Do not
use normal electrical tape as this will not provide an adequate seal against water .
the connectors should then be positioned where they are not directly exposed to the
elements .
Fuse replacement
If the fuse in the DC lead should blow, it should be replaced with a 2 amp 3aG type .
In the event of a failure, the use of a higher value fuse could result in damage to your
GR100 which would void the warranty .
