Audio signal converter to DMX-512 protocol.

The  PX245  is  designed  to  synchronize  music  with  lighting  control.  This  advanced  and 

customizable  driver  is  the  only  solution  of  this  type  in  the  offer  of  the  PXM  company.   

Device was placed in a housing of a width of 6 standard module rails equipped with a color LCD 

screen. This allows to program and control operation of the equipment in more intuitively way.

The  PX245  can  be  either  controlled  by  DMX,  or  act  independently.  In  this  case,  there  are 

available  16  fully  programmable  configurations.  Those  configurations  can  also  change  the 

parameters of audio signal processing.

USB connection allows you to communicate with the computer, the PXM company has created a 

software to manage the device configuration setting from the level of a computer running under 

®

Microsoft Windows .

2. SAFETY CONDITIONS

The PX245 is a device powered with safe voltage 12 V; however, during its installation and use 

the following rules must be strictly observed:

1. The device may only be connected to 12V DC current (stabilized voltage) with current-carrying 

capacity compatible with technical data.

2. All the conductors should be protected against mechanical and thermal damage.

3.  In  the  event  of  any  conductor  damaging,  it  should  be  replaced  with  the  one  of  the  same 

parameters.

4. Connection of DMX signal should be made with shielded conductor.

5. ll repairs and connections of outputs or DMX signal can only be made with switched off power 

supply.

6. PX245 should be strictly protected against contact with water and other liquids.

7. All sudden shocks - particularly dropping - should be avoided.

8. The device cannot be turned on in places with humidity exceeding 90%.
