safety notes
Please observe the following safety notes during
the installation and connection.
- Disconnect the negative pole of the battery! Observe
the safety notes of the vehicle manufacturer.
- When you drill holes, ensure that you do not damage
any vehicle components.
- The cross sections of the positive and negative cables
must not be less than 1.5 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 EMb 800A must be
secured in a professional way.
When selecting the installation location, select a dry
location that offers sufficient air circulation for cooling
the amplifier.
The EMb 800A must not be installed on rear shelves, rear
seats or other locations that are open to the front.
The amplifier power cable must be fitted with a fuse no
more than 30 cm from the battery to protect the vehicle
battery in case of a short circuit between power amplifier
and battery. The fuse of the amplifier protects only the
amplifier, not the vehicle battery.
Connection (see p. 2 /Fig. 1)
Connection 6 is connected to the positive pole of the
battery and connection 7 to negative vehicle ground.
The control of the EMb 800A should ideally be a two-
channel control, either via the preamplifier 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 preamplifier 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.

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°, filter (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 amplification of the bass level.
Next, use the crossover control 3 to select a filter setting
that provides a well-contoured bass. You may have to
alternately optimise the gain control setting 1 and the
filter setting 3.
A droning bass with excessive volume requires a filter
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 EMb 800A with the bass
control fully open and, if necessary, with activated loud-
ness. An overloading of the subwoofer box by selecting
an excessive amplification (pos. 1) results in a distorted
playback and can damage the loudspeaker.
