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
In the ideal situation, all components in the audio system reach maximum undistorted output at the same time. The reason is because an amplifier will only make what comes into it bigger. So, if you send it a distorted signal from the head unit, the amplifier is going to amplify distorted information. The same thing holds true if an outboard processor or crossover begins to distort before you have maximum output from the amplifier. By setting all components to reach clipping at the same time, you can maximize the output of your system. For the REFERENCE Class A amplifiers, follow the following steps for the quickest, easiest means of setting the levels.
1.Turn the amp’s input levels to minimum position (fully counter- clockwise).
2.Begin with the input level switch in the 0.5 - 5.0 Volt position.
3.Set source unit volume to approximately 3/4 of full volume.
4.While playing dynamic source material, slowly increase the amplifier’s input level until a near maximum undistorted level is heard in the system.
If your preamplifier / source unit has an extremely high output level, be sure to pay attention to the clipping indicators located on the top of the amplifier. These indicators will notify you if you are clipping the PREAMPLIFIER stage of the amplifier. If the amplifier's output is distorted and the clipping lights are not blinking, you are most likely clipping the OUTPUTS of the amplifier, or driving the speaker to distortion.
