Fuse replacement. Amplifier configuration. Subsonic filter cut-off frequency modification. Amplifier fixing. Electric connections. Input stage is provided with a special circuit LNS which allows the system disturbances rejection, reducing noise that is usually due to the vehicle electric parts alternator, electronic injection, etc. Driver stages are characterised by a very linear circuitry.
They have coupled differential transistors and an A Class complementary voltage amplifier. Thanks to its great capacity to supply current, to the use of a pair of BJT for every channel and of two pairs for the sub, this amplifier can easily drive even the hardest loads and satisfy whatever power needs.
Differently from what occurs with other amplifiers, LRx 5. Its big power reserve, its constant control at low frequencies and its exquisite timbre qualities make it an ideal amplifier to realise systems designed to attain outstanding musical features and very high sound pressures SPL. LRx 5. Constant Bass function is also available; it permits to control the subwoofer level whatever the head unit Fader adjustment is.
They also permit to configure the preamplified output OUT as additional input to accept the source output for Rear system. It will have to be equal to the sum of the values of all fuses in case system consists of several amplifiers or in case amplifiers have several fuses. In case LRx amplifiers are used in extremely difficult conditions very low loads or in installations where space is too narrow and their heat sink cooling is not enough, they can be employed together with CLK2 cooling system optional.
Once the causes which implied protection circuits intervention have been checked and solved, the amplifier is reset by switching it off and on again. The amplifier is also provided with another general protection which is insured by an internal strip fuse, very easy to reach. We suggest that you seize both plate grips with your hands and pull them by blocking the silkscreen printed panel with your fingers against the amplifier chassis at the same time. This will permit to remove the plate from the panel without damages.
Connect the speakers cables to these outputs according to polarity. Terminal blocks accept cables up to 9 A. We recommend the use of audison cable products. In three channel configuration 3 ch , the right channel R drives Front outputs in mono, while the left channel L drives Rear ones in mono.

The amplifier can go on functioning in these. F2 LEFT. LRx 5. Need help? Post your question in this forum. Report abuse Libble takes abuse of its services very seriously.
