Need help?Do you have a question about the SHOWTEC Single DP-1 and is the answer not in the manual?
The Showtec Single DP-1 is a versatile 1-channel DMX dimmer/switch designed for various lighting applications. Its compact and robust design allows for easy mounting on walls, trusses, or directly to fixtures, making it suitable for any location where precise lighting control is needed.
The core function of the Single DP-1 is to provide either dimming or switching capabilities for a connected light source. It operates as a DMX-controlled device, responding to signals from a lighting controller. This allows users to integrate it into a larger DMX lighting system for synchronized and dynamic light shows.
A key feature of the DP-1 is its "Highest Takes Precedence" (HTP) functionality. This means that if both a DMX input value and a manual fader value are present, the higher of the two will take precedence. For example, if the DMX input is set to a higher dimming level than the manual fader, the DMX input will control the output. Conversely, if the manual fader is set to a higher level, it will override the DMX input. This ensures flexible control, allowing for quick manual adjustments even when a DMX signal is active.
The device features a clear LED display and control buttons (MENU, UP, DOWN) on its front panel, enabling users to configure various settings. These settings include DMX addressing, selecting between dimmer and switch modes, setting a dimmer limit, and defining a dimmer preset.
In dimmer mode, the DP-1 provides gradual adjustment of light intensity from dark to brightest, offering fine control over the connected light source. In switch mode, it acts as a simple on/off switch, allowing users to toggle the connected fixture.
The Single DP-1 is equipped with a power failure memory. This ensures that the device retains its last active settings and operation mode, automatically restoring them in the event of a power interruption. This feature is crucial for maintaining consistent lighting setups and preventing unexpected changes after power fluctuations.
Setting up and operating the Single DP-1 involves a straightforward process. Users first connect the device to the main power supply and then connect their light source to the 10A Schuko output. DMX signal cables are connected to the 3-pin DMX IN and OUT connectors for integration into a DMX network.
The control panel is central to configuring the device. DMX addressing is performed by pressing the MENU button until the "A001" display appears, then using the UP/DOWN buttons to select the desired DMX address. The adjustment range for DMX addresses is from 1 to 512. Holding down the UP/DOWN buttons allows for fast address selection. The selected DMX address is automatically saved.
To switch between dimmer and switch modes, users navigate to the "d---" or "S---" option in the menu. "d---" configures the device as a dimmer, while "S---" configures it as a switch. In switch mode, further options "S-on" and "S-oF" allow users to manually switch the connected light fixture on or off, respectively.
The dimmer limit feature, accessible via the "L-10" menu option, allows users to set a maximum dimming limit value, ranging from 1 to 100. This is useful for preventing lights from reaching full brightness if desired. Similarly, a dimmer preset can be configured through the "P000" menu option, allowing users to set a default dimmer value from 0 to 100 (dark to brightest).
The device also includes a diagnostic feature for power stability. If the power frequency is unstable, the display will show "AC-0," indicating that the device needs to be connected to a stable power source or that users should wait for the power to stabilize at the current outlet.
For optimal DMX signal transmission, it is recommended to insert an XLR termination plug (with 120 Ohm) in the last fixture on the DMX data link. The device automatically detects DMX 512 data; if no data is received, the DMX LED indicator will not flash, prompting users to check cable connections, controller status, or signal integrity.
The Showtec Single DP-1 is designed for minimal maintenance, but regular checks are essential to ensure safe and reliable operation. Annually, safety-related and machine-technical installations should be inspected by a qualified expert. This includes checking all screws for tightness and corrosion, inspecting housings, fixations, and installation spots for deformations, and verifying that electric power supply cables show no damage or material fatigue.
Routine cleaning involves disconnecting the mains power supply and wiping the cover with a damp cloth. It is crucial not to immerse the unit in liquid. DMX connections should also be kept clean and dry.
In the event of a fuse burnout, which can be caused by power surges, short-circuits, or inappropriate electrical power supply, the fuse can be replaced. Users must first unplug the unit from the electric power source. A flat-headed screwdriver is used to turn and gently push the fuse cover to release the fuse. The used fuse is then removed, and a replacement fuse of the same type and specification (F10L/250V) is inserted. The fuse holder is then reinserted.
Troubleshooting simple problems involves a systematic approach:
The device is not designed for permanent operation, and consistent operation breaks will extend its lifespan. It is important to avoid operating the device in extreme heat (above 35°C ambient temperature or 80°C housing temperature) or high humidity (above 50% relative humidity at 35°C). Any operation outside the specified conditions may damage the product and void the warranty.
