33. DIMMER PATCH
Piccolo has all its channels ordered numerically and related to the
first dimmers outputs in the DMX line. The rest of the dimmers
outputs (up to 512 of the DMX line), are free and have no-
assignment. The relations of channels to dimmers are in the
dimmer patch table, and can be changed. Open the dimmer patch
by pressing:
[CHANNEL][CHANNEL] or [MENU][0][2]
In this table is the list with all system dimmers (or Dmx
addresses), ordered numerically. Each dimmer has a channel
associated (Cha), a response curve (Cu) and a limit value (Li).
A channel can control as many dimmers as needed.
A dimmer can only be controlled by a single channel.
Dmx
: List not editable. It is used for searching the table and is the table index
Li: Value for the limit function. The dimmer output level will never be higher than this level. If
the limit is FF (100%), the dimmer will be controlled in full range
Cu: Response curve of the dimmer (See later)
Cha: Is the associated channel
Fxt: Only a flag, showing the number of a possible assigned fixture that is using this dimmer for
its control. In this dimmer table it is no possible to edit this Fxt value
In the patch, it is possible to test any dimmer that is selected with the cursor; for this, turn the
Encoder. It is possible to capture the Test level as limit value, pressing [INSERT] key to Li
33.1. PRE-PROGRAMMED CURVES
Graphic presentation of the 5 pre-programmed curves of Piccolo. The vertical axis is the output
channel (in power) and the horizontal axis is the control level:
Linear curve, (1: LIN). Curve for linear
response in relation to the power. At the
50% control level, the output is the 50% of
the total power.
Square curve, (2: SQR). Is the curve
with a steep-start. At the 50% of control
level, the output is 70% of the total power.
This curve is used in TV studies, and in
Theatres, to compensate the slow start of the
lamps with a slow start.
Invert square curve, (3: INV). It’s the
curve of slow-start. At the 50% of control level, the output is 30% of the total power. This curve is
useful with fluorescent fixtures, and in Theatre, to compensate the fast start of some lamps with low
power.
On-Off Curve, (4: O-F) Is the Non-Dim curve. This curve does not dim. At 0% of its control
