Radius RSX12 Menus
Upon power on and initialization of the subwoofer the Main Menu is displayed. Here the user can
adjust the RSX12's output level, alignment delay settings, crossover configuration and user
preferences, 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.
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.
!
Initiating Output Check automatically or manually will cause the subwoofer to emit pink
noise. To ensure against potentially dangerous exposure to high sound pressure levels, it is
recommended that all persons exposed to equipment capable of producing high sound
pressure levels use hearing protectors while the equipment is in operation.
Auto:
Using the Auto mode, a 2-second burst of pink noise is emitted from the low-frequency
transducer. To initiate the Auto Output Check sequence, follow these steps.
1.
Rotate the DSP Navigation / Edit Wheel to select Auto.
2.
Press the DSP Navigation / Edit Wheel to initiate the automatic test procedure.
Note: Status changes from "Start" to "Stop". Press it again to terminate the test sequence at any point.
3.
A 2-second pink noise burst is emitted.
Note: When the subwoofer is emitting pink noise, its status changes to indicate "On". It changes back to "Off" after
the 2 second burst is complete.
4.
Auto status changes to "Start" to signify the end of the Output Check cycle.
