GME GA9800 Instruction Manual page 25

The GR200 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 GR200 . 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 GR200's output circuit .
The GR200 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 GR200 is connected, you can adjust the balance between the left and right
speaker using the Balance function .
auxiliary audio Input
Connect an MP3 player or other external audio device to the 3 .5 mm socket on the
Auxiliary Input lead mounted on the rear panel . To select the AUX input, press the Band
key repeatedly until 'AUX' 'In' is displayed .
A 3 .5 mm to 3 .5 mm accessory lead (Le74) is available separately from your GMe dealer .
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 GR200, 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 6 Amp 3AG type .
In the event of a failure, the use of a higher value fuse could result in damage to your
GR200 which would void the warranty .
