Radius RSX18 Menus

Upon power on and initialization of the subwoofer the Main Menu is displayed. Here the user can
adjust the RSX18's output level, alignment delay settings, crossover configuration and user
preferences, setup cardioid mode and initiate a test of the subwoofer's output.
If the Home Screen (see below) is displayed, pressing or turning the DSP Navigation / Edit Wheel
reveals the Main Menu.

Level

Selecting Level allows the user to adjust the subwoofer's output level in 0.5 dB increments ranging
from -10 dB to +10 dB. Rotating the DSP Navigation / Edit Wheel changes the level value and pressing
it returns to the Main Menu. After 5 seconds have passed with no change to the Level parameter the
Home Screen is displayed.

Crossover

Selecting Crossover allows the user to optimize the subwoofer for use with with other RADIUS models
simply by selecting "with RSX Top".
Selecting Variable allows the user to enter a specific corner frequency to optimize the subwoofer for
use with other loudspeakers. Rotate the DSP Navigation / Edit Wheel to highlight Var and then press
it. Rotate the DSP Navigation / Edit Wheel to dial in the preferred frequency in 1Hz increments. Press
DSP Navigation / Edit Wheel to enter the value.
Selecting Polarity allows the user to invert the subwoofer's polarity. Norm is the default mode.
Rotating the DSP Navigation / Edit Wheel changes the selected crossover settings in real time. Pressing the DSP Navigation /
Edit Wheel, or after 5 seconds have passed with no press or turn of the DSP Navigation / Edit Wheel,
the Main Menu is displayed.

Cardioid

Selecting Cardioid allows the user to configure the subwoofer for Cardioid functionality. In Cardioid
mode, 2 or 3 subwoofers must be stacked together with one facing toward the rear. In a 2 subwoofer
Cardioid setup, the top subwoofer faces to the rear. In a 3 subwoofer Cardioid setup, the middle
subwoofer faces the rear.
Pressing then rotating the DSP Navigation / Edit Wheel allows for selection of 1 (normal mode /
non-Cardioid), 2 or 3 (Cardioid mode) subwoofers. Once the proper configuration is selected (for 2 or
3 subwoofer Cardiod configurations) pressing then turning the DSP Navigation / Edit Wheel allows
the user to identify the position of the subwoofer in the Cardioid setup (top or bottom in a 2
subwoofer setup and top, middle or bottom in a 3 subwoofer setup). Once the proper position is
selected, pressing the DSP Navigation / Edit Wheel returns the user to the Main Menu. This procedure
should be performed for each subwoofer in a cardiod setup.

Delay

Selecting Delay allows the user to adjust the subwoofer's alignment delay in 1ms increments ranging
from 0 to 150 ms in 0.1 ms increments between 0 and 10 ms and in 1 ms increments above 10 ms.
For reference, the equivalent distance is displayed in meters and in feet. Rotating the DSP Navigation
/ Edit Wheel changes the delay value, and pressing it returns to the Main Menu. After 5 seconds have
passed with no change to the Delay parameter the Home Screen is displayed.

Output Check

The subwoofer's transducer and amplifier can quickly be checked without the need for an external
noise generator and any associated cables. It can be tested manually or via an automated sequence.
