Operation

The unit has two working modes. It can be used as a four-channel chaser or as a 1, 2, or 4 channel DMX dimmer pack. Please follow up the instructions below to operate the unit for your desired performance.

Chase Mode

Choose this working mode only when you want the device to act as a 4-channel chaser. This device has 16 built-in programs. You can select to run any of these programs specifically, or set the unit to chase in a random sequence among all 16 built-in programs for a more dramatic show effect. The chase speed can also be adjusted.

Connect your light fixtures to any of the eight power sockets available on the pack.
Use the mode button to select a chase mode: Chase mode is indicated in LCD display as “PA” followed by numbers 01-16. “PA” stands for Program Applied. If an “A” appears in the LCD display, you are in DMX mode.
Once you have selected CHASE MODE function, use the MENU button to select your desired program. The chase pattern is represented on the LCD display by “P” followed by two numbers. You may select any of the 16 built-in programs to run at a single time by pressing the UP and DOWN buttons.
To change your desired chase speed press the MENU button until the “SP” followed by two numbers is displayed on the LCD display. Use the UP and DOWN buttons to adjust the chase speed. A value of 99 will give you the fastest chase speed (about one step per 0.1 second). A value of 01 will give you the slowest chase speed (one step per 30 second).
You may change the light intensity by pressing the MENU button to select “d” on the LCD. Use the UP and DOWN buttons to change the light output intensity. 00 will give the lowest output and 99 will give you full intensity.

DMX Mode

Use this operating mode only if you plan to use the device as a DMX dimmer. This function will allow you to turn on or off and control the intensity of non-DMX with the use of a DMX controller. You may also set your dimmer pack to function as a 1, 2, or 4 channel DMX dimmer pack so you can combine the output functions.

Connect a DMX controller to your DP4 dimmer pack via the 3-pin XLR connector.
Connect your lighting fixture to any of the eight power sockets on the front of the pack.

a. Control the output to all four outlets with one DMX channel.
b. Group outlet channels one and two and group outlets channels three and four. The first group will be controlled by one DMX channel and the second group will be controlled by another DMX channel. This gives the pack a DMX value of two.

Use the MENU button to select the address settings, this will be indicated by an “A” in the first character of the LCD followed by three numbers.
