You can change any value in the presets column, then use the TEST key to review the curve with these settings active. This is shown below.

Features of each preset are:

EQ. There can be a completely different set of EQs for each preset. Simply select the preset you want on the “SYSTEM RESPONSE” screen where indicated.

Volume. This setting deviates the preset’s volume from the established system volume of the SMS-1. So, if you found during setup that 30 was a good setup volume for the SMS-1, then if you increased the volume for preset one to 40, the 40 volume would be invoked when preset one were selected for listening. If the system volume is changed (using the VOL + or VOL – keys on the remote), the preset volume is adjusted in lock step with the system volume.

Crossover, subsonic filter, phase and polarity settings. Normally these will not change from preset to preset. However, it may be that you are using different satellites for different listening modes and wish to set these settings individually for a specific preset. Note that the “setup” values cascade to the individual values for the presets, but you can change all the individual values if desired.

Contour frequency and level. These act as an “extra” EQ that can be used to
manipulate the frequency contour of your SMS-1 when this particular preset is invoked.
For example, notice that preset one raises the level by 3 dB at 35Hz – this is to
accommodate action/adventure movie content.
