INSTALLATION STEP 5 Class A 5.0 LEVEL SETTING The input levels are adjusted by means of the individual channel input level controls located on the front of the amplifier. This is a unique dual - s circuit that adjusts both level and gain. This topology maintains better Signal th minimal output. In the ideal situation, all components in the audio system reach maximum undistorted output at the same time. The reason is bec ause an amplifier will only make what comes into it bigger.
