22. To manipulate a parametric EQ, you can now use the LEFT and RIGHT arrow keys to move
the frequency up and down, and the SET + and SET – keys to change the Q value. Use the
UP and DOWN arrow keys to adjust the level of the EQ as before. A selected EQ that has
been moved, with its level raised and Q adjusted is shown below:
CAUTION: Using this feature could pose a danger to your subwoofer! It is possible to “stack”
EQs - that is, setting them to identical or similar frequencies and boosting the signal at that
frequency. Some users have configured their EQs to stack EQs at the lowest frequencies, such
as 15 – 20 Hz, thus increasing the bass output of the subwoofer. The SMS-1 will deliver this
signal directly to the subwoofer, and without adequate overdrive protection this could cause
damage to the subwoofer even at normal playback levels.
23. To unselect the EQ, press SELECT again, then use the right and left arrow keys to position
the cursor on another EQ if desired, and repeat step 22, until the room is equalized.
24. Once the room has been equalized, you may want to return to the SYSTEM SETTINGS
screen (by positioning the cursor over the NEXT field on the EQ setup screen and pressing
SELECT) and review/modify the presets. This step is required ONLY if you wish to
customize the presets. Before doing this, LOCK the Setup column by positioning the cursor
over the LOCK screen and pressing SELECT.
