LEVEL SETTING
HEAD UNIT
The input levels are adjusted by means of the input level controls located on the
front of the amplifier.
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, it 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.
Follow the below procedure for the quickest, easiest means of setting the levels:
1. Turn the amp’s input levels to minimum position (fully counter-clockwise).
2. Set source unit volume to approximately of full volume.
3. While playing dynamic source material, slowly increase the amplifier’s
input level until a near maximum undistorted level is heard in the system.
though the ratio with low output sources is better with the
Soundstream amplifiers than others, your best combination of output level and
Signal to Noise ratio
be achieved when the input levels are set between
500 and 2.5 V.
