Speaker Connections; Antenna Connection; Auxiliary Inputs - GME G-Deck Instruction Manual

imPortant:
Your G-DEK is able to maintain its memories
when it is switched off by the button by drawing power
directly from your battery via the Yellow 'mEmorY B+' lead.
although the memory backup current is very small (about 20
ma) it could eventually discharge your battery if left connected
indefinitely. the time taken to completely discharge your
battery could vary depending on its amp-hour rating and
battery condition.
if you do not run your boat's motor regularly or your battery is
not kept charged between outings (e.g. solar or wind charger),
we recommend you disconnect the Yellow lead each time you
secure or trail your boat. this is easily done by connecting the
Yellow 'mEmorY B+' lead via a master switch, which can be
switched off after each outing. this will mean you will lose all
your preset station memories and clock settings.
the blue (auto antenna) wire on the wiring loom supplies
12 volts when the G-DEK is switched on and can be used to
turn on an external device whenever the G-DEK is switched on.

sPeaKer ConneCtions

Caution: the G-DEK is a four-speaker system that requires
two separate wires for each speaker. Do not touch the speaker
wires together or allow them to touch other wiring.

a range of GmE speakers are available from your local GmE retailer.
When connecting the speakers, observe the correct polarity
as shown in the connections diagram on page 13. 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 G-DEK's output circuit and may result in the
radio overheating.
connect all four speakers as shown in the connections
diagram. adjust the Fader control for the required front/rear
balance. if you wish to connect only two speakers, connect
these to the rear speaker wires. the remaining speaker wires
should be insulated to ensure they cannot short circuit
together or to the vessel's 12 volt or negative electrical Bus. if
using only two rear speakers, adjust the Fader control to the
rear speakers.
antenna ConneCtions
the G-DEK includes an am/Fm tuner (the Gm550 also includes
a DaB receiver). as these operate on different frequency
bands, a separate antenna is required for each. For information
on suitable am/Fm and DaB antennas, contact your nearest
GmE dealer.
connect the am/Fm antenna to the larger antenna socket
(bayonet connector). the DaB antenna connects to the smaller
sma socket (Gm550).

there are two auxiliary inputs to allow connection of audio/
video from other external sources. auxiliary input selection is
made using the SRC button on the remote head unit.
