14 MAC 101 user manual

RAW and RGB modes include the same control options as BASIC mode, but they provide 4 extra channels

to give RGB control and CTC.

See “DMX protocol” on page 21 for details of the DMX commands available in the different modes.

Tailoring performance

Pan and tilt movement

The P/T SPEED settings set the maximum speed of pan and tilt movement. FAST optimizes for speed and

SLOW optimizes for smoothness of movement. NORMAL is the default setting and gives a good

compromise between these two.

The

PAN INVERT and TILT INVERT commands reverse the direction of pan and tilt, and the SWAP

command sends pan commands to tilt and vice versa. These settings are useful for symmetrical effects with

multiple fixtures.

Cooling

• FANS gives you a choice of two settings:

- The default setting

REGULATED should suit use in all normal situations and ensure excellent service

lifetimes for all components.

FULL maximizes cooling and reduces the operating temperature of the components in the head. It is

recommended when the MAC 101 is used intensively in a warm environment or in fixed installations.

Note that it will give increased fan noise compared to the other cooling modes.

Whatever cooling mode is selected, a thermal cutout shuts down power to the LEDs if the fixture

temperature exceeds safe limits. If this occurs, you must reset the fixture via the control menus or via

DMX, or cycle power to the fixture off and on again.

If a thermal shutdown occurs, you are pushing the fixture to its limits. Clean the fixture, particularly the air

vents, and check that there is sufficient airflow around the fixture. Consider increasing ventilation,

reducing the ambient temperature, or switching to

FULL mode. Contact Martin for service if a thermal

shutdown persists.

Dimming

• DIMMER CURVE provides four dimming options (see Figure 3):

LINEAR – the increase in light intensity appears to be linear as DMX value is increased.

SQUARE LAW – light intensity control is finer at low levels and coarser at high levels.

- INVERSE SQUARE LAW – light intensity control is coarser at low levels and finer at high levels.

S-CURVE – light intensity control is finer at low levels and high levels and coarser at medium levels.

Restoring factory default settings

The MAC 101 factory default settings can be restored by applying a FACTORY DEFAULT → LOAD

command.
