INSTALLATION
The
HV sedici
amplifier is characterized by its relatively compact size considering the
performances it offers.
This makes installation possible even in the most unlikely places. For mounting use 6 self-
threading screws provided.
IMPORTANT: The wooden moulding which protects controls on top of the device must
be removed before installing. This is done by loosening the three screws through the 5mm
allen key provided. Once the installation and calibration have been made, mount the
wooden protective moulding. For excellent results it’s advised to use
audison
cable
products to complete your installation. They include: power cables, signal cables, speaker
wires, signal connectors and all accessories needed to complete the wiring.
INPUTS CONNECTIONS
Pin ABS CONNECTORS (
Inputs
). Observing polarity, connect L-R inputs to respective
preamplified outputs of radio-cassette player, preamplifier or electronic crossover. In order
to make UNBALANCED signal connections (traditional connection), it’s possible to use
pin RCA connectors used in almost all electronics on the market. In order to make
BALANCED signal connections ( taking the signal from a balancer-preamplifier outputs)
it’s necessary to use ABS signal connectors which you can find in
audison
cable
catalogue.
In case of unbalanced connection and in case the radio-cassette player doesn't share the
signal GND (preamplified outputs) with the battery GND (chassis of the device itself), the
shield of the shielded cable must be connected to the radio-cassette player chassis.
BALANCED-UNBALANCED CONNECTION
Balanced:
Position BALANCED-UNBALANCED push-button to BALANCED. For
the amplifier inputs use the ABS connectors in Audison cable catalogue taking the
preamplified signal from a device provided with balanced outputs.
Unbalanced:
Position BALANCED-UNBALANCED push-button to UNBALANCED.
In the UNBALANCED position device can be used in the unbalanced way (traditional
way) and it’s therefore possible to employ common Pin RCA signal connectors. For
sensitivity values , refer to the technical features chart on the controls area of the device.
CONNECTION TO EXTERNAL PREAMPLIFIER
Position the PREAMP push-button to OFF position (internal preamplifier exclusion). In
this case the amplifier sensitivity decreases and it is necessary to connect the device inputs
to an external preamplifier.
The sensitivity can be adjusted from a maximum of 1.0 VRMS to a minimum of 5.0 VRMS
in unbalanced configuration (
±
0.5 VRMS to
±
2.5 VRMS balanced).
With the PREAMP push-button to ON position (internal preamplifier on), the sensitivity
changes from a maximum of 0.2 VRMS to a minimum of 1.0 VRMS in unbalanced
configuration (
±
0.1 VRMS to
±
0.5 VRMS balanced).
The chart on the controls area shows the different sensitivities according to the operative
modalities of the amplifier.

PRECAUTIONS
1) In order for this device to function properly it’s important that it is installed in a spot
where the temperature is beetween 0
°
C (32
°
F) and 55
°
C (131
°
F)
2) It must be installed in a dry and well ventilated spot.
3) Power supply voltage is 12 VCC, negative to ground. Make sure that the characteristics
of the vehicle electrical system are suitable.
4) For safe driving, it’s advised to listen to music at a volume level that won’t drown out
external traffic noise.
