[. . . ] 3 % THD - Tolerance: +10 %; -5 % - Continuous power given by RMS Voltage measured on resistive load - The nominal power of the amplifier is measured upon a battery voltage of 12 Volts with a 4 Ohms load and with all channels in function. The outstanding features of its sophisticated circuitry are : "FRONT END" stages realized by two complementary differential stages, final stages made of transistors in Darlington connection, final transistors with in current capacity of 15 A and MOSFET PWM power supply with high energy reserve. [. . . ] LR 605 XR is designed in order to be used with an accessory kit for the SUB volume remote control. VCR01K consist of three parts: 1) Volume control (VCR01); 2) Module to put into LR 605 XR (VCA); 3) Connecting cables between VCR01 and the proper pins on the LR 605 XR power outputs panel. 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 (32°F) or rise above 55°C (131°F). Make sure that the caracteristics of the vehicle electrical system are compatible with this device. For safe driving we advise to listen to music at a volume level that won't drown external traffic sounds. 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 wires, 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. If a crossover filter is used, be sure its two channels don't have a common ground. [. . . ] IN Turn on control for the amplifier coming from radiocassette player (or from any sources provided with remote control for amplifiers). It has to be connected to the REMOTE IN of the following amplifier to allow the simultaneous turning on of the whole system. [. . . ]
