CHARACTERISTICS:
LR 3042, LR 3062: Two-channels amplifiers with compact dimensions and excellent
musical performances.
The outstanding features of their sophisticated circuitry are: "FRONT END" stages
realized by two complementary differential stages, final stages made of an inverted triplet
at pure complementary symmetry, final transistors with current capacity of 15 A and
MOSFET PWM power supply with a high energy reserve.
The design of the LR 30 (LR 3042 - LR 3062) dimensions allows their easy functioning on
2 Ohms nominal loads in stereo configuration and 4 Ohms nominal loads in bridge mono
configuration.
These features allow a great use versatility both in driving multiway systems and in the
SUBWOOFER mono connection in TRI-MODE configuration.
PRECAUTIONS
· In order for this device to function properly it's important that it is installed in a spot where
temperature doesn't fall below 0° C or rise above 55° C.
· It must be installed in a dry and well ventilated spot.
· The power supply voltage is 12 VCC negative to ground. Make sure that the characteristics
of the vehicle electrical system are compatible with this device.
· For safe driving we advise you to listen to music at a volume level that won't drown out
external traffic noise.
INSTALLATION
For mounting use 4 self-threading screws and protective plastic rings provided.
For a very good result we suggest to use audison cable products to complete your
installation. These include:power cables, signal cables, speaker cables, RCA connectors
and all accessories needed to complete the wiring.
WARNINGS
· INPUTS: If the radio-cassette player doesn't share the output GND with the chassis, the
braided shield of the shielded cable must be connected to the radio-cassette player chassis.
· OUTPUTS: Never connect the -R and -L outputs to ground or to each other.
If a crossover filter is used, please be sure its two channels don't have a common ground.
· REGULATIONS: If you hear saturation phenomena at moderate volume levels, it means
a distorted signal is coming from the radio-cassette player.
Turn radio-cassette player down until there's no longer any distortion.
Then adjust the calibration levels of the amplifier until you can hear only light saturation
phenomena.
