Note! 
If the fixture is connected to a 
controller, please disconnect it. 
The display will read the previously 
selected setting. 
Only one fixture can be the Master 
assigned fixture. However, 16 units 
can be slaved to the master unit. 
Operating Modes 
  A stand-alone mode will listen to sound and run through its diverse range of built in programs. 
  Master/Slave mode will allow the command of up to as many units you want in a synchronized 
light show to the sound. 
  DMX control mode will provide the greatest flexibility and creativity. Each fixture trait can be 
controlled individually using any universal DMX-512 controller. 
Master & Stand Alone (P6) 
In order to create the correct environment for Stand Alone 
operation, several parameters have to be set in the control 
panel. Please make the changes to the functions as listed in 
the table below.

Setting Slave Fixtures 
The Master/Slave mode will allow you to link multiple units in a daisy chain fashion. In this mode, the 
first unit in the daisy chain, the master, will automatically command all other units following. The first 
unit will operate in a Stand/Alone mode and all units following will synchronize to the first unit. Up to 
16 fixtures can be daisy chained in Master/Slave mode.
