Positive/negative connection
The cross section of the positive and negative cables must be at
least 6 mm 2 .
Use cable grommets to protect cables against sharp-edged holes.
Securely screw a standard 6 mm
ence-free earth connection point (bolt connected to the car body,
car body sheet metal) - though do not connect it to the negative
terminal of the battery. Scratch the surface down to the bare met-
al at the point at which the earth contact is made and apply graph-
ite grease.
Connection examples
Connecting the voltage supply ................................................... Fig. 2
Connection to car radios with RCA AUX-OUT ........................... Fig. 3
Loudspeaker connections .......................................................... Fig. 4
Connecting the wire remote control (REMOTE GAIN) .............. Fig. 5
The switching line must be connected when connection is carried out
using the RCA jacks or the loudspeaker jacks of the car radio.
GAIN control
You can use the GAIN control to adjust the input sensitivity of the
Velocity power amplifier to the AUX-OUT voltage of your car radio's
preamp AUX-OUT.
The setting can be adjusted between 0.3 V and 8 V.
When connecting a car radio produced by another manufacturer, you
must adjust the input sensitivity in accordance with the information
provided by the manufacturer.
Please note that the GAIN control is not a control for adjusting
the volume!
REMOTE GAIN
Connection for the supplied wire remote control (5 m).
This gives you the convenience of controlling the bass GAIN remotely
(see Fig. 5).
If you want to use the remote control, the device must be operat-
ed with the low-pass filter activated (XOVER switch set to posi-
tion LP).
INPUT
Preamp inputs for the right and left channels. Please use high-quality
Velocity RCA cables for this connection.

XOVER switch
Before installing, adjust the XOVER switch on the power amplifier to
set the low pass filter (LP), high pass filter (HP) or full range (FULL). If
you select the FULL position, the full frequency response will be used
at the output.
Using the integrated XOVERs is particularly useful in the case of mul-
ti-channel sound systems with a separate subwoofer.
In order to obtain the best sound when a subwoofer is connected, the
subwoofer must be separated as far as the frequencies it receives are
concerned, i.e. it must only be fed with low frequencies (bass).
To ensure that this is the case, select LP and use the XOVER frequen-
cy control to adjust the upper frequency to between 50 Hz and 250 Hz.
This ensures that every subwoofer is optimally separated as far as the
frequencies it receives are concerned.
If HP is selected, you can use the associated XOVER frequency con-
trol to adjust the lower cut-off frequency to between 50 Hz and 250 Hz.
If you want to precisely optimise the acoustic settings of the XOVER,
we recommend you obtain advice from a Velocity dealer.
It is very important that you take into account the specifications
of the loudspeakers being used whilst you are adjusting the
XOVER.
XOVER frequency control (LOW PASS + HIGH PASS)
If the XOVER is activated (LP or HP) by adjusting the position of the
XOVER switch, you can then use the corresponding control to adjust
the XOVER frequency of the respective filter to anywhere between 50
Hz and 250 Hz or 50 Hz and 250 Hz (i.e. continuously variable set-
ting). This control has no function in full range mode.
Settings for a subwoofer
In order to obtain the best sound when a subwoofer is connected, the
subwoofer must be separated as far as the frequencies it receives are
concerned, i.e. it must only be fed with low frequencies (bass).
1. Firstly, turn down the GAIN control on the amplifier to minimum
and set the LOW PASS frequency control to its centre position.
2. Now play some music on your car sound system that you are very
familiar with and that contains some low bass (e.g. pop music).
Now slowly increase the volume of the subwoofer by turning the
GAIN control on the amplifier in a clockwise direction until you feel
that the sound of the music is well balanced, i.e. the bass is neither
too weak nor overpowering.
3. Now listen to the relationship between deep male voices and the
upper bass and also take note of the relationship between the up-
per bass (kick bass) and the lower bass. The bass should ideally
+12V
sound crisp and have a clear low bass component, and male voic-
es should neither sound too weak nor should they billow out. You
can stop making adjustments if you are happy with the sound. If
not, move on to steps 4 and 5.
4. If male voices seem to billow out or the low bass is too weak, you
should turn the LOW PASS frequency control slightly towards min-
imum and then continue making your adjustments as described in
point 2 onwards.
5. If the bass sounds low but dirty and booming or the male voices
sound too weak, you should turn the LOW PASS frequency control
slightly towards maximum. Next, continue making your adjustments
as described in point 2 onwards.
If you want to precisely optimise the acoustic settings of the XOVER,
we recommend you obtain advice from a Blaupunkt dealer.
It is very important that you take into account the specifications
of the loudspeakers being used whilst you are adjusting the
XOVER.
SUBSONIC
The subsonic filter is used when a subwoofer is connected to the am-
plifier. It can be adjusted in order to protect the subwoofer against
mechanical overload due to low bass frequencies that fall outside our
hearing range.
