DSP User Control Menu Operation
A two-line, 16-character per line LCD and a rotary push-to-select encoder make up the interface for this prod-
uct.
The DSP processing control accessible by the user, consists of a 9-band graphic equalizer (GEQ), choice of output
Polarity, selection of Bass Enhancement, and signal Delay. This is applied to the powered speaker system, and in
some cases, to the processed output. The user can also select from a menu of preset Program EQ settings that are
applied to the graphic equalizer and Bass Enhancer.
User interface:
Rotating the encoder takes the user thru the top level menu screens. These screens will display current infor-
mation such as a Input Level meter, configuration and current user settings. Pressing the encoder on a top level
screen will take the user to related selection screen(s) when relevant. The configuration screens play an im-
portant role in preparing the speakers for the intended application. The configuration screen comes up after the
initialization screen when the speaker is powered on. If the configuration screen is not selected within 5 minutes
the Input Level screen is displayed . The user can still select this screen at any time by rotating the edit knob.
The configuration screens help the user set up the SP®2P system for optimal operation. By answering a couple of
questions, the processor is configured and proper connections displayed. When complete, the user is returned to
the main menu.
The LCD backlight will dim after 5-minutes without interface activity but returns to full brightness when the
encoder is moved. When the backlight auto-dims, the display returns to the Input Level screen. This prevents
inadvertent changes from occurring while reactivating the LCD backlight.
The main menu screens are:
