Over the years, Light-O-Rama has released several different versions of MP3 directors. Here are some pictures and descriptions to help you determine which MP3 director you have and what it's functionality:
Generation 1 LOR MP3 Directors
Generation 1 MP3 directors include the DC-MP3 and the original mDM-MP3 director.
Your DC-MP3 director may be just a plain circuit board, in a metal case that only contains the director, or as part of an LOR1602 controller:
DC-MP3 Board
DC-MP3 in Case. Some cases were labeled DC-MP3 rather than LOR1602MP3.
DC-MP3 as part of an LOR1602
The mDM-MP3 Mini Director is in a black plastic case. The mDM-MP3 and the uMP3g3 look similar. Be sure you carefully check the front of the unit. the uMP3g3 will explicitly say it is a uMP3g3, while the older mDM-MP3 will not. The uMP3g3 also has a power input connector that the mDM-MP3 does not.
The Front and Back of an mDM-MP3 Mini Director. Carefully compare these pictures to the uMP3g3 to ensure you have identified the correct version that you have.
Generation 3 LOR MP3 Directors
Light-O-Rama did not manufacture any Generation 2 MP3 directors. Generation 3 MP3 directors include the G3-MP3 and the uMP3g3 Mini Director
The G3 MP3 director was sold in a metal case, or as part of an LOR160xMP3g3 controller.
Stand Alone G3MP3 Director
G3 MP3 Director as part of an LOR1602MP3g3. LOR1600MP3g3 similar. Note: the LOR160xg3 looks similar but does NOT have an MP3 Director
This is an LOR160xG3 that does not have an MP3 director.
The uMP3g3 was sold in a black plastic case. It looks similar to the older mDM-MP3 director but has significant differences.
The Front and Back of the uMP3g3 Mini Director. To identify if you have a uMP3g3 or a mDM-MP3: the front of the uMP3g3 identifies it as such. On the back of the uMP3g3 there is a power socket, while on the mDM-MP3 there is none.
Generation 4 LOR MP3 Directors
G4 MP3 Directors come in several variants, including the N4-G4-MP3 a metal case 4 port MP3 director with Director Link, 1 and 2 port black plastic directors without Director Link, and a 2 port adapter with Director Link will be available in the future.
