12 Stagebar 2 user manual

Fixture setup

The control panel and backlit LCD display on the Stagebar 2’s rear panel allows you to set DMX addresses

and alter various fixture settings. The Stagebar 2’s onboard battery makes the most important fixture setup

functions – such as DMX address setting – available when the fixture is not connected to AC power.

• Press Menu to access the menu or go up one level.

• Press Enter to confirm a selection.

• Press Up and Down to navigate in the menus.

The current menu level is displayed in capital letters and sub-menus or menu items are displayed in small

letters in the LCD display.

See “Onboard control panel menus” on page 23 for an overview of the menus available in the control panel.

DMX mode

Color control mode

Martin use the highest quality components based on the most advanced technology available. However,

despite rigorous quality assurance and manufacturing tolerances, there are very small variations in color

rendition between LEDs. Stagebar 2 fixtures are therefore tested and set up at the factory so that pixels give

evenly matched color in RGB, HSI and HSIC modes. Settings are stored in EEPROM on fixtures’ main

PCBs.

The DMX MODE → control mode menu allows you to set the fixture to respond in one of four color

control modes:

RGB (red, green, blue)

In RGB mode, all LEDs (including amber and white) are active in red, blue and green color output. The

intensity of each color is controlled on one DMX channel, giving RGB additive color mixing.

RGBAW (red, green, blue, amber, white)

RGBAW is a ‘raw’ control mode in which the intensity of each color LED is controlled on one DMX channel.

LED intensity is thus not managed by the fixture software based on its factory settings, but is controlled

directly by the user. The factory settings are designed to ensure even color rendition across pixels and

fixtures. By bypassing these, RGBAW mode can allow slightly more saturated color.

HSI (hue, saturation, intensity)

In HSI mode, one DMX channel controls hue (selects a color), one channel controls saturation (adjusts

depth of the selected color) and one channel controls intensity (brightness of the selected color).

HSIC (hue, saturation, intensity, color temperature)

HSIC mode is identical to HSI mode, but with the addition of color temperature control on a fourth DMX

channel that allows easy adjustment of the color temperature of white light output.

Pixel grouping

The DMX MODE → pixel grouping menu also allows you to set up pixel control (one pixel is one of the

six blocks of LEDs in a Stagebar 2). You can control each pixel individually, so that each pixel displays its

own color and is controlled using its own DMX channels, or you can control pixels in groups. Pixels in a

group use the same DMX channels and behave identically. The options available are:

• 1 (each pixel is controlled individually)

• 2 (pixels are controlled in pairs, giving three groups of 2 pixels)

• 3 (pixels are controlled in two groups of 3 pixels)

• All (all pixels are controlled together in one group)
