Basic Description of Colortran D192 (Dimension 192) Dimmer Rack

This equipment, D192, was available both in full sized racks (192, 2.4Kw dimmers), as well as 12 channel portable packs. Both racks and packs used the D192 dimmer modules, which were available in dual 2.4kw, 6.0kw, and 12kw sizes.  This dimmer line was particularly robust, and is still in use in many, many facilities. The original release for these racks was 1984, and they continued to be produced through 1991.  The D192 dimmers had provision for 1 multiplexed control input, typically “Colortran” multiplex. This could later be upgraded, with a simple change, to DMX-512, today's current industry standard.  The D192 rack was laid out as 3 vertical rows of dimmers, each row 32 dimmer modules tall. Each vertical row was fed from it’s corresponding phase (a, b, or c), and could be split fed from 2, 3 phase sources. (the rows split upper and lower).  The control modules lived in the bottom slot of each vertical row, and had 4 pilot lights each. The indicators are: signal (green, and indicated some signal on the multiplex or analog lines), upper and lower (each indicating a valid power feed to each half of the vertical row), and airflow (this indicated whether the blower vane switch was open or closed).  Also, analog control could be used to control certain of the slots within the dimmer rack. Turning on these slots turned on all the analog inputs to the available slots (the bottom 3 dimmer module slots in each vertical row, with a maximum of 18, 2.4kw dimmers). There is not possible to patch these analog signals to particular slots. The analog patch assignments are permanently fixed in the hardware.
