Level Setting - Soundstream Reference 200 Owner's Manual And Installation Manual

The input levels are adjusted by means of the input level controls located on the
front of the amplifier. This is a unique dual-stage circuit that adjusts both level
and gain. This topology maintains better Signal to Noise ratios even when using
sources with minimal output.
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 amplifiers, 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 314 of fult 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 Smr ratio with bw output sources is better with the
NOTE: Even
REFERENCE amplifiers than others, your best combination of output level and
Signal to Noise ratio will be achieved when the input levels are set between
