12 MAC Encore Performance User Guide
Fixture ID
The MAC Encore Performance lets you set a four-digit ID number to ease identification of the fixtures in an
installation. When a fixture is powered on for the first time, it displays its DMX address by default. As soon
as you set an ID number other than 0 in FIXTURE ID, the MAC Encore Performance will display this ID
number by default, and indicate FIXTURE ID in the display.
Personality
The MAC Encore Performance provides several options that let you optimize the fixture for different
applications in the PERSONALITY menu:
• The PAN/TILT menu lets you swap and/or invert pan and tilt.
•This menu lets you put the fixture into FOLLOWSPOT MODE. In this mode, control of pan and tilt via
DMX or the control panel is disabled and pan and tilt movement are unlocked. This allows the head of the
fixture to be aimed by hand using user-supplied handles mounted on the back of the head. The pan and
tilt motors are energized so that they act as a gentle brake. This feature gives a damped feel and smooth
control for followspot operators and also prevents the head from moving when operators remove their
hands from the fixture.
The fixture remembers its followspot mode setting if you cycle fixture power off and on.
• The LIMIT PAN/TILT feature lets you set minimum and maximum limits for pan and tilt. This can be useful
in a number of situations. It lets you ensure that the fixture only lights a specific zone on a stage, for
example, and can also be used to prevent the head from colliding with other fixtures or objects.
• The SPEED menu lets you set PAN/TILT to NORMAL, FAST (optimized for speed) or SLOW (optimized
for smooth movement – useful for slow movements in long-throw applications). Likewise, you can select
an overall speed for all the effects by setting EFFECT speed to NORMAL, FAST or SLOW. You can also
set effect speed to FOLLOW P/T, in which effects will always use whatever speed is set for pan and tilt.
• DIMMER CURVE provides four dimming options (see Figure 5):
- LINEAR – (optically linear) the increase in light intensity appears to be linear as DMX value is
increased.
- S-CURVE – light intensity control is finer at low levels and high levels and coarser at medium levels.
This curve emulates the RMS voltage dimming characteristics of an incandescent lamp such as the
tungsten halogen lamp of the Martin® MAC TW1.
- SQUARE LAW – light intensity control is finer at low levels and coarser at high levels.
- INV SQUARE LAW – light intensity control is coarser at low levels and finer at high levels.
• TUNGSTEN EMULATOR is an option that gives the look and feel of a tungsten lamp. The default color
temperature of the MAC Encore Performance CLD variant is shifted to match the WRM variant, and a
gradually increasing red shift is introduced as both variants are dimmed down. A slight lag is also added
to dimmer and shutter response to simulate the warm-up and cool-down behavior of an incandescent
source.
• ALTERNATE COLOR TEMP deploys the CTC flags to shift the fixture’s default color temperature. This
setting can be used to match CLD and WRM variants visually in color temperature and color mixing
behavior.
• FOCUS TRACKING sets focus to automatically self-adjust, giving sharper focus when you use the zoom
effect.
• VIDEO TRACKING
optimizes performance if the MAC Encore Performance is used with a video source.
