Safety precautions
Instructions for installation and connection
Fit a fuse in the amplifier power line no more than 30 cm from the vehi-
cle battery, in order to protect the battery in the event of a short-circuit
between it and the power amplifier. The amplifier's own fuse protects
the amplifier itself, but not the car battery. Disconnect the negative
terminal of the battery before carrying out installation and connec-
tion work.
Observe the vehicle manufacturer's safety instructions (regarding air-
bags, alarm systems, trip computers, vehicle immobilisers).
The final stage must be installed professionally for reasons of safety.
The mounting surface must be suitable for the screws provided, and
must provide firm support.
When drilling holes, take care to avoid damage to vehicle components
(battery, cables, fuse boxes).
Fit the amplifier in a suitable location, e.g. beneath the seats or in the
trunk (Fig. 1). The mounting location must also be dry, and provide suf-
ficient ventilation for cooling of the amplifier. Use cable grommets when
passing cables through holes with sharp edges. Use loudspeakers with
an impedance of 2 to 4 Ω (see table or installation drawing). Observe
the max. power handling specifications (music output). Do not connect
the loudspeakers to ground; only use the terminals provided. The cross-
section of the positive and negative cable must be at least 6 mm
GTA 2200 amplifier
The amplifier is suitable for connection to car radios with Cinch connec-
tor. Use the Blaupunkt ISO Cinch adapter to connect the amplifier
to car radios with ISO connector. (7 607 893 093/ 7 607 855 094)

Positive/negative connection
We recommend a cable cross-section of not less than 6 mm
standard commercial positive cable to the battery and connect to the
fuse holder. Use cable grommets when passing cables through holes
with sharp edges. Bolt a standard commercial negative cable to a ground
point free of induced noise (car body bolt, body panel) - not to the neg-
ative battery pole. Clean the contact surface of the ground point down
to bare metal and coat with antiseize graphite petroleum.
Integral fuses
The integral fuses within the amplifier protect the final stage and the
entire electrical system in the event of a fault. Never bridge fuses or
replace fuses with a higher current rating.

+12 V power source.
This enables the amplifier to be switched on and off with the radio's On/
Off switch.
Level control
The Level control enables the input sensitivity of the final stage to be
matched to the output voltage of your car radio preamp output.
The range of adjustment extends from 0.3 V to 8 V.

Adjust the input sensitivity in accordance with the manufacturer's spec-
ifications when connecting the amplifier to other radios.
Important: Turning the Level control clockwise increases the input sen-
sitivity of the amplifier, and thereby also the volume. The Level control is
however not a volume control; an increase in volume is not achieved in
the maximum position, even if this subjectively appears to be the case.
The system merely increases the volume more quickly when the vol-
ume is turned up on the radio.
Loudspeaker connections
(If the amplifier is to be connected in a bridged mode, proceed with the
section "Bridged loudspeaker connections".)
As with any audio component, connection of the amplifier and speakers
with the correct polarity is essential for good bass reproduction. Ensure
therefore when connecting that the positive (+) amplifier terminal is con-
nected to the positive (+) loudspeaker terminal. The same applies to the
negative (-) terminals. The left-hand amplifier channel must also be con-
nected to the left-hand loudspeaker and the right-hand amplifier chan-
nel to the right-hand loudspeaker.
Bridged loudspeaker connections

.
The GTA can also be bridged in a mono configuration. This enables you
to use the amplifier for one or more subwoofer(s) or a mid-range speak-
er. In this configuration the amplifier sums the right-hand and left-hand
channels, delivering a single channel (mono) output.
Note: The amplifier can sum the right- and left-hand signal information
only if both the right- and left-hand RCA connections have been made.
CAUTION: The amplifier must be presented with a load of 4 Ohms
or higher in bridged mode. A lower load will cause the amplifier to
overheat or switch off. This can lead to permanent damage of the
unit.
GTA 2200
The type of crossover (i.e. "low-pass" or "hi-pass") and the desired cros-
sover frequency can be selected on the GTA 2200. If, for example, you
wish to drive a pair of subwoofers, connect in accordance with the low-
pass diagram (fig. 2a).The crossover frequency is dependent upon the
loudspeaker frequency range (consult the loudspeaker manufacturer's
data for the recommended frequency range).
"High- Pass" frequency control
This control is active when the switch is in the "Hi-pass" position, and
permits selection of the desired crossover frequency. Example: at a of
65 Hz, the loudspeaker has a frequency range of 65 Hz to
26.000 Hz.
"Low-pass" frequency control
This control is active when the switch is set to "Low-pass" and permits
selection of the desired crossover frequency. Example: at a setting of
40 Hz, the loudspeaker has a frequency range of 40 Hz to 10 Hz.
