DESCRIPTION Audison LRx 5.600: Five channel car power amplifier characterised by excellent musical performances, small size and outstanding energy reserve. Its PWM power supply stage is made with two pairs of 70A MOSFETs; it is stabilised and oversize. 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.), without altering musical signal quality.
IN-OUT PANEL INSTALLATION FUNCTIONS LOGO ROTATION 1 - Remove the transparent cover which protects controls and then the 4 screws which block the metal plate by using multispanner. 2 - Remove the plate without damaging the silkscreen printed panel which will have to stay on. 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.
POWER SUPPLY PANEL CONFIGURATION EXAMPLES 3 CHANNEL FRONT+REAR FUNCTIONS Pre Out 1 REMOTE IN Terminal to connect Remote cable, which comes from the source and which controls the amplifier switching on. Applied voltage must be between 7 and 15VDC. Front Rear 2 POWER IN OUT REMOTE 1 3 FUSE 2 4 5 LRx 2 Config. 3 REMOTE OUT Terminal to repeat the switching on control (Remote IN) coming from the source. It is used to switch on another amplifier or device in the system simultaneously.

CONTROLS PANEL CONFIGURATIONS FUNCTIONS AND CONTROLS CONFIGURATIONS TABLE 1 LIMIT (orange LED) It indicates the Overload Limiter circuit is on. Caution: When this led is on (although sporadically), it means the applied load is a hard one. The activation of Overload Limiter circuit (output power limiter) will anyway allow the amplifier to function without distortions.
CONTROLS PANEL CONFIGURATIONS BLOCK DIAGRAM STEREO SIGNAL BAND-PASS LO-PASS BY - PASS module BYP12 HI-PASS 40÷150 Hz INDEPENDENT FREQUENCY CONTROL 16÷32 R Hz ON by-pass SUBSONIC subsonic 24dB / mono R SUB F1 24dB / mono 40÷150 Hz REAR TWEETER 12dB / Oct. F3 mute MIX MIX L N S F4 It permits to adjust the woofer 12dB/Oct. LO-PASS filter and the Mid-Tweeter 12dB/Oct. HI-PASS filter crossover frequencies between 150 Hz and 5 kHz. It works only in Multichannel configuration.
SETTING PANEL ACCESSORIES FUNCTIONS Installation: It permits to reach the switches for the amplifier configuration, the resistors to set subsonic filter cut-off frequency and to insert VCA modules for the subwoofer volume remote control. Setting panel Remote 1 - Remove the setting panel in the amplifier bottom in order to carry out operations. First fan Second fan 2 - Once operations have been carried out, please close the setting panel. AMPLIFIER CONFIGURATION LRx 5.
ACCESSORIES SETTING PANEL CLK2 - LRx Cooling Kit SUBSONIC FILTER CUT-OFF FREQUENCY MODIFICATION This cooling system is specially designed to provide LRx amplifiers with the right working temperature. CLK2 should be used when LRx amplifiers work in extremely hard conditions (very low loads) or in installations where space is too narrow and heat sink cooling is not enough. It consists of two units to apply onto the amplifier sides; each of them is provided with an electronically controlled fan.
ACCESSORIES TECHNICAL FEATURES VCR01K,VCRAK and VCRDK SIZE FOR FIXING 445 mm 176 mm 119 mm 412 mm LRx 5.600 can accept one of the optional kits that allow the subwoofer volume remote control. VCR01K and VCRAK are analogue and special for sub; VCRDK is digital and can be used for master volume control or for level control of any ways in a multichannel system.
