The sensitivity of the D Beam controller can vary depending on the 
amount of light in the vicinity of the controller and the object (e.g., 
hand, bass neck) used to operate it. Perform this adjustment so you 
can control the tone in the intended range.

 

• First, hold the object you will use to activate the controller (your 

hand, bass neck, etc.) at the point farthest from the VB-99 in the 
range you want the controller to respond, and press [F1] 
(SetMIN).

• Next, hold the object at the closest point in the range you want 

the controller to respond, and press [F4] (SetMAX).

 

• The D Beam controller’s response may also vary with the stage 

lighting used. Confirm operation of the controller by testing it 
onstage under the actual illumination.

• If the set range is too narrow or if the positioning is not suitable, 

the message “OUT OF RANGE! SET AGAIN.” appears. To keep 
this message from appearing, change the range or position and 
recalibrate.

• The controller may not function properly with spot lights or 

other such lighting shining directly on it.

• Be sure to adjust the CALIBRATION directly above the D Beam 

controller.

• When the message “MISSING THE TARGET!” appears, it 

indicates that the calibration is not being performed correctly.

• The CALIBRATION setting is a system parameter, so the Write 

procedure is not required.
