THb 210A
- When you drill holes, ensure that you do not damage
any vehicle components.
- If the positive and negative cable are extended, ensure
that the cross section is not less than 2.5 mm

.
- An incorrect installation can result in malfunctions of the
electronic vehicle systems or your car sound system.
Installation and connection instructions
With respect to accident safety, the THb 210A must be
secured in a professional way.
When selecting the installation location, select a dry
location that offers suffi cient air circulation for cooling
the amplifi er.
The THb 210A must not be installed on rear shelves, rear
seats or other locations that are open to the front.
The installation location must be suitable to accept the
accompanying screws and provide a fi rm support (see
page 2 / Fig. 1).
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 THb 210A 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
THb 210A automatically switches off.
Connection (see p. 2 /Fig. 2)
Connection 6 is connected to the positive pole of the
battery and connection 7 to negative vehicle ground.
The control of the THb 210A should ideally be a two-
channel control, 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 portion of the music is generally identical
on both channels.
The preamplifi er outputs are connected to the cinch (RCA)
sockets of the woofer box via a shielded sound cable.
To connect the device, we explicitly recommend the use of
the original Blaupunkt RCA cable 7 607 885 093 (1.3 m) or
7 607 886 093 (5 m).
With control via the loudspeaker outputs, the input con-
nections of pos. 9/: are fed to the closest loudspeaker
cables (front or rear) on the left and right. They are sepa-
rated and connected to the input connections. The polarity
of the + or - connections must be observed. Bridge output
stages (BTL) can also be connected directly without an
additional adapter.
TIM function:
For car sound systems with activated TIM function, the
THb 210A must be controlled via the loudspeaker outputs of
the car sound system and not via the RCA inputs (see page 2
/ Fig. 2 of the car sound system operating instructions).

Settings
The following control setting is recommended as basic
setting before putting the device into operation: Sensitivity
(gain) pos. 1 to minimum, phase pos. 2 to 0°, fi lter (cross-
over) pos. 3 to approx. 80 Hz. Switch on the device and
select a musical piece with distinctive bass playback.
Increase the volume of your stereo system to the desired
volume level. Now slowly increase the gain control 1
until you can hear a clear amplifi cation of the bass level.
Next, use the crossover control 3 to select a fi lter setting
that provides a well-contoured bass. You may have to
alternately optimise the gain control setting 1 and the
fi lter setting 3.
A droning bass with excessive volume requires a fi lter
setting with a low frequency.
The phase switch must be set so that the bass is integrated
into the acoustic pattern as best as possible and not re-
cognisable as an individual source.
Also check your settings of the THb 210A with the bass
control fully open and, if necessary, with activated loud-
ness. An overloading of the subwoofer box by selecting
an excessive amplifi cation (pos. 1) results in a distorted
playback and can damage the loudspeaker.
Recycling and disposal

available to dispose of the product.
