All six presets contain the following fields:

Low Pass Crossover Frequency and Slope – Adjust the upper limit of your SMS-1’s frequency response. Select a crossover setting, in increments of 1, between 15 Hz and 199 Hz (or OFF) and slope at 6, 12, 18, 24, 30, 36, 42 and 48 dB/octave.

Subsonic Filter Frequency and Slope – Set your SMS-1’s subsonic filter (low frequency limit), in increments of 1, between 15 Hz 35 Hz and slope at 6, 12, 18, 24, and 48 dB/octave.

Phase – Set the phase (delay) of the SMS-1’s output signal, 0 to 180 degrees (adjustable in 15 degree increments).

Polarity – Set your SMS-1’s polarity by toggling between positive (+) or negative (-). This in effect reverses the phase 180 degrees.

Volume – Each preset can have its own volume separate from the master volume shown in the setup column. When the master volume changes, the preset volume changes in lock step.

Contour Frequency – This allows you to set a frequency to boost or cut the signal to your SMS-1 in response to specific types of source material. These have been preset at the factory according to the presets above, but any or all can be customized to taste.

Contour Level – This indicates the amount of boost or cut at the frequency specified in the contour frequency. Again, this has been preset at the factory but can be adjusted to taste.

Other controls on the Setting Setup Screen:

12 Volt Trigger Mode – When active, this control automatically shuts the SMS-1 off until 12 volts is detected via the connector at position 18 on the back panel.

Night Mode Maximum Volume – When the NIGHT mode button is pressed on the remote, this setting is invoked. Night mode is indicated on the LCD display. The SMS-1 will not play louder than this volume level until the night mode is defeated.
