(Calibrated Level Eliminates Audible Noise) setup system. From the driver's seat, you'll be able to adjust the amp's output level and monitor its incoming signal for distortion. After using C.L.E.A.N. technology to set your amp's gain, just keep an eye on the PLC2's light. It'll turn red when the musical source is distorting, warning you to turn the receiver's volume down before your speakers or subwoofer suffer any damage.
