The amplifi er power cable must be fi tted with a fuse no more
than 30 cm from the battery to protect the vehicle battery in

case of a short circuit between power amplifi er and battery.
The fuse of the amplifi er protects only the amplifi er, not the
vehicle battery.
Switching on/off
One of the special features of the GTb 200 A is its automatic
switch-on.
The subwoofer box automatically switches on if a music
signal is received.
If there is no music signal for more than 60 seconds, the
GTb 200 A automatically switches off .

battery and connection
control of the GTb 200 A should ideally be a two-channel con-
trol, either via the preamplifi er outputs or the loudspeaker
outputs of the car sound system. A control solely via the right
or left channel is also possible since the low-frequency por-
tion of the music is generally identical on both channels.
The preamplifi er outputs are connected to the cinch (RCA)
sockets of the subwoofer box via a shielded sound cable.
With control via the loudspeaker outputs, the input connec-

For car sound systems with activated TIM function, the
GTb 200 A must be controlled via the loudspeaker outputs
of the car sound system and not via the RCA inputs (see
