HOW TO SELECT LIGHTING COLOUR
You can choose three different colours, green, red and orange, in order to make VCRA lighting suitable to
the car dashboard it is installed on.
In order to set the colour you like, remove VCRA chassis through the two rear screws and connect the two
jumpers to the connector as indicated below. There is a short caption on the printed circuit board inside
VCRA that explains how to carry out this simple operation.
• Red (R):
position 1 and 2
• Orange (O): position 2 and 3
• Green (G): position 1 and 3

the device).
Warning: Make sure alcohol does not
damage the possible plastic where you drilled
the hole using it on a hidden place first.
Remove one of the two protective films from
the bi-adhesive tape and apply it on VCRA

FEATURES
VCRAK is a kit for the subwoofer volume remote analogue control that permits to easily adjust the
amplifier output level without moving from the listening point. It consists of:
1. VCRA level control to place close to the listening point; it has variable lighting (red, orange and green)
and intensity (Dimmer).
2. VCA (Voltage Control Amplifier) module, to put inside the amplifier to control.
3. Connection cables kit.
VCRAK, based on VCA functions, can be only used with the components that are suitable to accept this
module.
When designing it, we minded not to affect the
signal path in order not to affect sound itself.
SUBWOOFER
VCRA varies VCA module reference voltage,
that is proportional to the signal level to
modify; this makes preamplified signal stay
unchanged.
REMARK: VCA module is stereo. This
VCRA
level
allows the amplifier subwoofer section
VCA module
control
mono/stereo modes not to change according to
the amplifier features or to the chosen configuration.

INSTALLATION
There are six sockets in VCRA rear panel, supplied with small spring terminal blocks to connect to
power supply (battery) and amplifier. Please follow instructions and connections diagram for a
correct installation.

GROUND: -12 VDC, to be connected to battery negative (-).
REMOTE IN: Input for the cable coming from the source or the amplifier; it switches
on internal lighting.
+12 VDC: Battery positive (+).
LIGHT SW: Control to decrease internal lighting when the car lights are turned on. To
be connected after the lights switch.
VOLUME CONTROL: Outputs to connect to the amplifier VCR sockets.
REMARKS:
1. The two contacts of VOLUME CONTROL sockets are equivalent and not polarised. They can be
connected to the two VCR sockets of the amplifier through the white-yellow wire as you like.
2. Please refer to the amplifiers owner’s manuals in order to install VCA module.
We recommend the use of audison cable products in order to have a very good installation.
PRECAUTIONS
In order to insure the system good functioning, avoid to install VCRA in hot or damp places.
Respect power supply voltage polarity.
For safer driving, we recommend to adjust volume not to drown external traffic sounds.

CONNECTIONS
Press the screwdriver point on the terminal block, then insert
the peeled cable to the hole bottom. Release the terminal block
insuring the cable perfect fastening. Repeat the operation with
the other contacts.
WARNING: Use the cables given with the device.
Otherwise, please use cables with 1 mm maximum diameter,
peeling their ends for about 10 mm.
Cables preparation:

VCRAK USE
VCRA level control has a knob with central tripping (“0” position). If the knob is adjusted on this
position, subwoofer volume stays unchanged.
If you turn the knob counterclockwise, you gradually decrease subwoofer volume until it is completely
silent.
If you turn the knob clockwise, you gradually increase subwoofer volume until its output level
doubles.
ADJUSTMENTS
1. Set VCRA knob on the central tripping.
2. Adjust output levels of the system channels through a standard calibration.
3. Adjust subwoofer volume by turning VCRA knob according to your needs.
