FEATURES
XR2F2 crossover is characterised by high performances and very easy use. It can solve the most
important acoustic problems that affect car hi-fi systems.
All active filters configurations inevitably have advantages and disadvantages. Our choice of one of the
numerous typologies was determined both by electrical and acoustic considerations. The configuration we
adopted is Bessel with low group delay, which insures correct acoustic alignment. Filters slope is
18dB/Oct.; it provides transducers with safer and more linear functioning than cuts with lower slope can
do. Filters frequency is adjusted through a 5 step switch, in order to be able to filter all speakers systems.
Resistors switching (1% tol.) and selected capacities (1% tol.) insure the filter constant performances and
frequency high precision. The device has 3 inputs to handle FRONT, REAR and SUBWOOFER systems
and has HI-PASS FRONT, HI-PASS REAR and LO-PASS SUBWOOFER outputs. The three outputs can
be driven by Front input only, excluding Rear and Subwoofer inputs through the proper switches on the
crossover back. Each filter section has a level control (+6 ÷ -12dB) and a cut-off frequencies switch.
Subwoofer section is also provided with a subsonic filter (30 Hz – 24 dB/Oct.) to eliminate rumble noise
from special CDs with very stressed bass. It has an adjustable boost filter (0 ÷ +6dB) set at 45 Hz that
makes Subwoofer frequency response wider and more even. It is also provided with a phase inverter
(0°/180°) and a Mono-Stereo switch that permits to mix Left and Right channels for mono subwoofers.
Subwoofer output level can be adjusted through VCR01 remote control (it is an accessory), to be installed
near the head unit; it can be activated and connected to XR2F2 Remote Sub Level section on the device
back.
PRECAUTIONS
Avoid to install the device where temperature is below 0°C or above 55°C.
The device needs 12VDC power supply voltage with negative to ground. Be sure that your car electric
system is compatible with the amplifier ordinary functioning.
For safer driving, we recommend to adjust volume not to drown external traffic sounds.
INSTALLATION
For mounting, insert the metallic supports into their location and fasten them through the 4 screws and
spacers given with the device. In order to get the best from your system, we recommend the use of
audison cable products, which include power supply cables, signal cables, RCA and RCA ABS
connectors and all accessories necessary to complete your wiring.
WARNING
If the radio-cassette player output ground is not connected to the radio chassis, the braided shield of the
shielded cable must be connected to the radio-cassette player chassis. If you hear saturation at moderate
volume level, it means a distorted signal is coming from the radio-cassette player. Possible saturation
phenomena could be caused by an input or an output signal higher than 4 VRMS. In this case you need
to adjust the radio-cassette player volume to a lower level until distortion disappears; then, adjust the
levels of the crossovers and of the amplifiers connected to it.
