The high impedance inputs of the LC8 will accept two, four, six or eight amplified speaker level channels (up to 400 watts!) and convert them to a high quality pre-amp signal. The pre-amp signal can then be used to drive a superior after-market audio system, utilizing an OEM source unit. In addition the LC8 has an internal summing circuit that allows the user to combine together selected channels making the LC8 ideal for newer vehicles that have factory-installed amplifiers with built-in electronic crossovers. Other installation friendly features include a unique signal sensing turn-on circuit and a 12-volt output for turning on aftermarket amplifiers. Most factory-installed systems do not have a separate 12-volt trigger to turn-on external processors and amplifiers. The LC8 actually monitors the signal at its speaker level inputs and when it senses an audio signal, it automatically powers up the LC8. Once powered up, the LC8 in-turn provides a 12-volt output that can be used to turn on after market amplifiers and processors.
