Dimensions

WxHxD (mm) 361 x 60 x 300

Positive/negative connection

The cross section of the positive and negative cables must be at

least 6 mm

Use cable grommets to protect cables against sharp-edged holes.

Securely screw a standard 6 mm

negative cable to an interfer-

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.

The switching line must be connected when connection is carried out

using the RCA jacks or the loudspeaker jacks of the car radio.

+12V

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.

AUX-OUT

AUX-OUTs for connecting an additional amplifier (formation of chains

of amplifiers). Please also 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

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.
